I'd encourage the OP to discuss the matter with Lloyds, I've only ever found them to be fair and show a genuine desire to do right by their customers. For the record I run a Canems engine management system, it was one of their first installations and in the last five plus years has never given me the cutting out issues described.

As the first company to really offer TVR Griff and Chimaera owners a true drive in drive out engine management solution with loom, Lloyds have completed hundreds of these conversions and tales of problems do seem conspicuous by their absence. I'm just saying its important to put things into perspective, do keep in mind while you do get a new loom with the Canems ECU none of these engine management conversions replace all of TVR's interesting wiring efforts.

I'm sure Lloyds will find the fault, the truth is it could be a thousand different things so may or may not have anything to do with the Canems ECU and/or it's loom, until the fault is traced we are all just speculating. I would take confidence in the fact there are hundreds of Canems installations out there all working with 100% reliability, indeed it's probably the most common after market ECU fitted to these cars.

On the other hand, the original TVR wiring is well known for it's err ( and lets be charitable here) rather questionable quality! It's a little early to blame the Canems ECU, loom or the Lloyds installation as in my experience there's a far greater probability there's a bad earth, or the now 20 year old TVR rats nest fuse board hash up has a bad connection, or the poorly wired alarm/immobiliser system is your underlying issue.

Just three examples in a long list of potential issues that have nothing to do with the engine management installation or ECU.

So why havnt they found the bad earth.
Hundreds of installs. That's actually funny.
Someone managed to thrash the engine on a dyno but couldn't find this fault, ( or didn't look)
Charges for the privilege then the guy stutters home for 6 hours.
Some expert that is.
Dave, Tvr wiring horrors like you talk of don't exist. It's your imagination.
There's hardly any wires in a Tvr FFS.

WTF are you on about Alun confused

Because clearly its an intermittent fault.

Why would facts be funny Alun?

Your use of the word 'Thrash' is clearly designed to be inflammatory, what RPM did your beloved Powers Performance take your engine to to give you your dyno graph?
Classic Chim said:

If it presented itself it would have been addressed for sure.

Classic Chim said:

From what I've read he didn't stutter home so more inflammatory language there, disappointing Alun, from what I read the OP had an intermittent fault that clearly didn't present itself when it was with the experts

I assume this is a joke?

Honestly mate, I can see how keen you are to find issue with other engine management installations, that's only natural if you've invested in the offering from a competitor, but such an attitude is more than a bit short sighted. What you need to know is like all industries the TVR world is full of people who work very hard to prove they are the best which is fine but it's those that work equally hard to prove their competitors are incompetent who show themselves in a poor light. Its important this over eagerness to see others fail or prove one has made a better decision doesn't translate into embellishing a problem on forums without even seeing the car, by cleverly coaching their customer base certain specialists don't even need to publicly do this dirty work themselves as they know how disrespecting a competitor looks to others.

Coaching your customer base in this way is quite sad, much better to let the quality of your work do the talking, and no body buys "I've never made a mistake, and all my work is flawless" bull, don't be manipulated Alun and used as a puppet by others. You may feel you're displaying loyalty and so securing a stronger relationship with your specialist because you've become reliant on him if things need tweaking, but I'd encourage you not allow yourself to be drawn into that game especially as you really don't know the full story behind the OP's issues.

I say it as I find it, I can only give my personal experiences of Lloyds which has always been positive, I'm sure from time to time they've made mistakes as I am equally sure Powers have made many mistakes in the past too. I'm not defending anyone here but merely trying to put some perspective on the situation and give my personal experiences with Lloyds. As tempting as it must be for you to jump on a post like this and smugly insinuate incompetence, your eagerness to do so does not show you in a good light and reveals an uncharacteristic side I can only assume is being coached out of you by your specialist.

As I said in my original response none of us know the full story here, so we really shouldn't be making the type of comments highlighted above, what we do know is Lloyds have hundreds of extremely reliable Canems installations under their belt and thousands of happy customers, these are facts. Don't fall into the trap of jumping on something like this when you don't really know the full story just because you want to prove to yourself and others you made a better decision. The truth is in any competitive business situation an unhealthy over eager desire to see your competition fail is usually born of a fear of that competition, as such you have to take it as flattery rather than the criticism it appears to be on the surface.

I recommend the OP returns to Lloyds to discuss his problem as I am sure they will want to resolve it just as Powers will want to resolve the issues they will undoubtedly have from time to time, using a forum as a waepon to get something fixed your unhappy with is not the way to go about things. Issues are just a function of the type of industry both specialist are in, unless Powers have grown wings and a halo don't tell me they get everything 100% right first time always, and as we don't even know what the issue is with the OPs car it's extremely unfair to assume at this stage it's down to something Lloyds have done

Like I say I'm not defending anyone here, no one is perfect, I'm just stating the facts as we know them which is different to jumping on a few limited details and piecing them together to make assumptions that fit our own objectives.

What a total load of nonsense.
It's you clearly blinded by faith.
I'm on this thread because I have an after market Ecu and don't want any of us to suffer problems with any of them.
We are all stuck in the same situation regards who can fettle our particular brand of Ecu and I'm only saying what others can't.
What I will say is if you take an interest Jason will openly teach( help you ) learn mapping.
If this was MBE I'd be just as keen to find out what's wrong.
This has nothing to do with brand loyalty
Your some boy you, instead of thinking about what the problem is you attack me. On your bike.
Your post was loaded with sales pitch ffs.
I happen to know what the wiring looks like on both Ecu.
You are the one who persisted in blasting on about the brilliance of Canams and regularly listed MBE at the bottom of your list.
I've just consistently informed folk of my experience on Mbe and frankly I'm blowing you away.
Re maps, problems on installation.
I'm absolutely sure POWERS have had any and all these faults to deal with over the years.
I pay the same as others do for the work,any insinuation I'm getting looked after is totally incorrect.
And to be clear about one thing. Dyno thrash your engine to get the numbers and pit it at risk! Road balance can never be re created and vibration/ loading on the engine isn't great.
The less you do it the better.
Let's not get into yet more spats as this is simply distraction.
Soemethings very wrong if the car had been to a respected specialist ( whoever it may be) with a known fault before going in there, then comes back with the same fault. The customer found the fault on the way home. All,I can think is whoever the specialist was they didn't test drive the car for long enough to see the fault or the fault didn't appear, but it did for the poor customer on his journey home. It's been recorded that others have had what amount to minor faults on this particular Ecu.
I'd be very interested to know from people who have had problems with MBE or related issues, namely other electrical problems since install that cause problems with ignition or Ecu that apparently isn't the fault of the system or its installation.
As Dave makes the point, we don't know this is Ecu but you'd think the experts could find it and tell you what it is. What's the op meant to do now.
Brilliant.

This is daft Alun, re-read my post, its not an attack on you.

I'm just trying to help you think a bit before making comments and assumptions about a situation you or I know little about.

These are people's livelihoods, all I'm saying is its very unfair to stir a pudding when you don't have all the facts.

There's only one piece of good advise in such situations and that's to discuss it with the specialist who I'm sure will correct the issue which could as easily be the immobiliser or a thousand other things that aren't connected with the ECU or it's installation.

A few corrections for clarity:

Classic Chim said:
Sounds like Ecu to me
How can you possibly say that from the comfort of your arm chair having never seen the car?

Classic Chim said:
Do you have the resistive plug caps or have they been removed, you really should use resistive plugs.
Laughably obvious first principle stuff Alun, but please feel free to call Lloyds to tell them this little known fact, I'm sure they will thank you for your expert advice in this matter.

Classic Chim said:
Charges for the privilege then the guy stutters home for 6 hours, some expert that is.
You really should read the OP's comment properly, he had a terrible journey home mostly because of traffic, what should normally be a 3 hour drive from Warminster to Dover turned into a six hour nightmare due to traffic, the intermittent fault didn't help I'm sure but to say he stuttered home for six hours is stirring the pudding again.

Classic Chim said:
Has the earths inside the car been checked. I'm sure Canams use the bolt on top of the transmission tunnel left side of gearblever, hidden under carpet by dash. It has a number of wires earthing there, maybe that's at fault. But why I'm saying this I'm not at all sure.
I'm not sure why you're saying it either Alun confused, the Canems ECU earths to the negative battery terminal not the the bolt on top of the transmission tunnel, stirring the pudding is one thing, offering complete misinformation is another.

Classic Chim said:

Actually if you look back I have always been clear to state MBE, Emerald, Camems, MegaSquirt all do the same thing, with the exception of the recent developments to fit the GEMS system to our cars in engine management terms all the above are just batch fired wasted spark systems which is really just mid nineties tech.

This is not an attack on you Alun, just a reminder to be fair on the forum when you don't know all the facts, while I appreciate how tempting it must be to jump on this to insinuate the Canems product and its installation is at fault doing so just isn't fair. For the record there are literally thousands of Canems ECU's out there and many of them are not fitted to TVRs, Gardner Douglas use them exclusively as do many others.

Here's my mate who's just come back from a 2,800 mile blat around Europe in his Canems equipped 1967 Porsche 911, like my car it never missed a beat wink



There's really nothing wrong with the Canems product as fundimentally it's no different to an MBE, MegaSquirt or all the others as they all use the same electronics inside their boxes, don't tell me the components in all the above aren't sourced from China, because like all the electronics in our homes China is where electronic components are made these days. On the other hand do a search on PH for 'Random Cutting Out' and you'll find it's not uncommon on 14CUX equipped cars, it's an inarguable fact the wiring on these cars was poorly executed so with all this in mind the likelihood the OPs issue is TVR wiring related is far greater than it being Canems ECU related.

Just be careful painting a picture for others reading your comments when you don't know all the facts, LSD are honest decent people that don't need that kind of unfair criticism and bad press on a forum when it's difficult for them to defend themselves without being drawn into a business damaging spat. I'm sure they will defend themselves in the way they always do, no not my responding on this post, but by looking after their customer, its clear from all this why PH need to adopt their name & shame rules.

The op says the condition was there prior to the fitting of the Canems and has remained since the fitting of the new ecu.

Accepting Carsy's point above that a shunting problem was there before the install does not excuse the garages - whoever they may be - from playing darts parts to solve the problem and charging the OP a huge amount of money for nothing. The fuel pump has been replaced which is a simple job especially in a garage with a lift and a Bosch replacement is around £120. The claim that another garage found bad wiring to the pump seems to be a red herring as the car performed exactly as it did before and after the so-called fix.
I'm struggling to see how this could be anything other than an electrical fault. I'm not familiar with Canems but if it has a data logger facility that might be a help surely?
A simple test would have been to fit a different ECU with a basic map to allow the car to be driven to see if the fault recurred. That would have eliminated the Canems instantly if the fault persisted.
The rolling road achieved nothing other than to suggest, to me at any rate, that the fault appears when the car is driven on the roads. This points towards a poor/bad/loose connection that is triggered by vibration. However, I would not discount Kate's experience above which is entirely plausible.
I am surprised that well known garages have not carried out in-depth testing of the wiring as there really is not a lot in an old school car - no canbus etc. Even a simple 'wiggle test' as used by Ford can often find faults in pre canbus wiring.

What I find inexcusable is that garages are taking a lot of this customer's cash for effectively doing absolutely nothing. If they do not want to take on 'intermittent faults' as they can be a nightmare, then they should say so upfront.
A very disappointing experience for the OP.

P.S. If the Op or anyone else out there is not familiar with the lengthy posts by our old friend Chimpongas and his relentless posts about the wonders and benefits of his Canems system with LPG, please do take the time to read this thread with particular emphasis on the posts by SimonYorkshire, an undoubted expert in his field of LPG. You may find the rather childish replies by our old friend less than helpful....

?
OP purchased the car in June of this year and Canems was fitted in 2013. There's no mention of a condition existing prior to fitting of Canems.

This really should not be rocket science and if the loom etc as been inspected/confirmed all good its very easy to substitute a known good ECU with the cloned map from the possibly/maybe suspect current ECU just to take this out of the equation nerd I think this should be rectified at no further cost to the OP'er if you cant fix something you cant charge for it regardless who are the garage and I am not suggesting a hanging here of whoever maybe responsible for overlooking/missing this fault its how things are dealt with from now on IMO scratchchin give the garage/specialist time to deal

My exasperation is nothing to do with what Ecu it has but the lack of collective brains that have worked on it,rolling roaded it and not been able to find a fault yet the customer finds it on his way home. He also went there with the fault.
Whatever my friends problem with his system was it was an Ecu problem.
As you well know Dave I was not exactly interested at the time as I had my mind on other very desperate details to deal with but essentially this is what it amounted to. The fact Rich re worked that loom at all is a good point.
Talking about people's livelihoods, COG
Isn't it time you answered the very real questions asked by a real expert in LPG who has no doubt been brought into question by you Dave before you rip into another Tvr owner trying to help understand this problem.
You have offered no such advice, who's being manipulated now is the real question.

I might be inaccurate which is sort of inexcusable and as I've also tried to say a few times, this could be something else but if you read my first posts on this hopeful thread I'm all in favour of all these Ecu.
The fact the MBE install and ability is second to none is just a fact. smile
Customer care from many places leaves a lot to be desired once the monies in the bank.
Don't be kidded by any of them.
You get what you pay for and in all these Ecu cases it's pretty much the same cost whoever installs it.
If I lived south I'd probably have a Canams by now as it makes sense to be close to the expert.
I fully believe this will or even is being sorted as I speak.
If an injector or other reason is causing issues that fault diagnosis surely will be charged for as that's not a system failure. Tracing it to a connection at the alarm or other which is related to Ecu install is still an installation fault as wiring correctly attached and protected should last decades not 5 years!

I'm out. frown

Glad to hear you were properly looked after, a public hanging on the PH forum for what likely amounted to a loose wire causing an intermittent fault that couldn't be replicated on a test drive may seem acceptable to some, but as you haven't had the car long, the Canems system was fitted some 4 years ago, and it's history since is less than clear since I really think this one should be put down to a case of 'These Things Happen'.

I haven't had any loose wire issues with my five year old Canems insulation, but I can certainly see how a ham fisted previous owner hauling out his battery in a clumsy way to replace it could strain the main ECU live feed wire and stress it's connection, you could hardly blame Lloyds for that and its something that could happen just as easily on any such ECU installation that takes it's live off the battery. The good news is you were properly looked after so people can climb off their hobby horses and put away their pitchforks safe in the knowledge LSD stand by their work and the Canems product isn't the unreliable pile of junk some will try to have you believe.

Its never nice to have an intermittent issue like this especially when you paid top dollar for the car, I hope your TVR experience improves and your faith is restored in the excellent Canems system?

It's pretty obvious we all support the people who we feel justify the praise.
Lloyds as we all have come to respect seem to have found a very basic fault and good on them. This thread wouldn't exist if it was found sooner. wink

Well done for persevering with it V8 Junkie. I stand by my comments that this should have been done at the beginning, not after the 'parts darts'.
As some of us have tried to point out, these cars are not rocket science. Most ECUs have a permanent live, a switched (ignition) live and an earth. Simple really.
Anyway, enjoy the car driving
