Ecu upgrade, what to expect ?
Discussion
^^^^^^^ this.
Just a little update, Doms rolling road is being calibrated, I'm patient,,sometime next week I'll be dropping the car off for full mapping session/s and to sort my sticky gear shift. It's had a new clutch but getting gears is not clever!
I might be doing stage two of my France trip
but this time in the Tvr,, new ucu, hopefully everything running tickity boo, see if I can get say 23-24-25 mpg out of a 4.6 ?
So I'm still only using the car occasionally and do get an amount of stutter,,, but seems better on fuel
Smells much less, even with the odd bit of shunting it's easier to drive,
Cooling system, and temp is far more stable, never to hot,,,,
It's a transformation of how it feels and a different level of confidence comes about, total belief it will start and run smoothly,,,
So next week get her upto speed and onwards and upwards

What you twittering on about; how do you think you turn a bike at anything more than a dribble? Not be steering left for going left that's for sure! Yeah, Mallory is ok I guess
Without that Mickey Mouse chicane the bikes are deemed to be coming down the hill onto the pit straight to fast,,
I've seen a side car get it wrong and sure enough,, riders nearly ended over the fence and into the pits,,,,
Safety,,,,ruins the flow but in some cases you can see the point.

Snap! Mine will be there too next week. Hope the new unit can handle all this power....So next week get her upto speed and onwards and upwards
Then we can do some serious
. 
I don't think they have enough days in the week at Doms place right now ? Even on my standard engine spec it can be two days work to get a map running well, my view is, it might take a number of sessions to get your map working in all ambient temp situations,,
Having had it installed the benefits are right in your face so to speak,, obvious, better than I'd hoped, a little tweaking hear and there over a period of time,,,should be good for years after that, without the rolling road issue my car would have been mapped weeks ago.
Im easy about though,, the changes made are there for a long time to come, hopefully.

On a rolling road
You'd be better calling Dom and asking him?
I'll develop an interest one day but I'm never going to map the car so right now I'll let Jay do it and see what I can learn from there.
COG Has been talking about closed loop, controlling idle,, that has sparked more interest in reading up but right now Daz I'm just interested in the results,,,
I've also decided I want drivability and economy and forget about horse power,,, my car is fast enough for what I want the car for, I'm not even going to increase Plenom size,,, I quite like it standard...ish...
The economy debate,,, Daves massive success with Lpg does get you thinking,,,
If I'm to use the car as regularly as I'd like it's important I get a usable car, ultimate power never comes into my thinking anymore, I'm not interested, but a car that can do hundreds of miles everyday and give a healthy fuel return does matter to me,,, old age maybe,, nah,,, just good sense because I'll drive it for longer and further
My engine right now seems smooth as silk, if I could maintain that equilibrium over 10's of thousands of miles,,,,
I've cracked it;)

Yeah it seems like good sense to me too.
The fuel economy debate,, I was once of that opinion,,it's a Tvr, it's fast, it's gonna drink fuel, but the more I think about it the more I think getting the fuelling perfect for the daily driving, slow, light throttle openings etc is a must if these cars are to be kept on the road, as cars have better economy figures than ever before,, it's the only drawback from using the Tvr more!
I've never known a time when I don't consider fuel expensive,, so I've always got the best economy out of my cars,,
I enjoy getting good figures, the fastest drivers are also often the ones who use the least fuel too it's a good trait so as I feel like some long distance driving is coming on,, I want to see what this Mbe system can do,, it's not going to be drastic but 23 mpg is better than 19 and so on.
As with Dave COG has a fasination with lpg, I've realised I have a fasination for getting good running economy figures,,,
Dave bugs me with his pics of cheap fuel,,,
and his numbers,,, impressive to say the least,
I rode my two cylinder motorbike across a thousand miles of mid France at 90 mph and it returned at least 75 mpg,,,,
Door to door it cost 60 quid in petrol,,,,,, it's f
king unbelievable but it happened,,,,
At that sort of cost,,, if you can hack it,,, the worlds your oyster on a bike as cheap as that,,,
So it brings me smack bang back to the car, if the car could do say25/26 mpg on a steady throttle setting,, long runs etc,,
Rather than 20 mpg and worse in traffic,,, over time that's a real saving but more importantly you feel good about it and use your car more,,,, hence keeping them on the road for longer and more often.
The fuel efficiency debate should be hotted up,,, with decent after market Ecu etc, we have the technology to maximise this area as we can the ultimate power curve etc,
So an after market Ecu install costs a couple of grand,,, considering the doors it opens up and how your car should run there after,, no disi caps/rotors,,,never over/under fuelling, consistent electrical signals and readings,,,
We buy tyres cos we need them,, buy a decent Ecu install and only then will you realise how much you've given the car,,
It will pay that couple of K back in no time,, just in peace of mind.
After all that I found a good point,,, peace of mind,,,
That's it in a nutshell,,,,,, even when my Cux ran well I was always listening for the odd misfire or when something was going to go down,,, my guts always a bit tight,,,, as soon as I turn the key now the engine runs with this proficiency and clean burn that's confidence boosting, very rarely do I sit at lights and smell the fuel,,, stuff like that,,,
I've had a few good engines,, Xj6 for one,,, I bet I could Rev my Tvr engine and it would settle back to tick over and still the 50p would be standing,,,, I'm not the only one I'm sure,
This last big step replacing the engine management system has been the best thing I've done,,,,,, just thought I'd waste an hour telling you that

Ain't that a flipping ace bike,, the more I look the more I see,, it's magnificent and that nutter of a rider,,, who's he think he is,
He's all counter steer and bar pushing
top boy,,, What does/did that bike weigh?
I was in ore of those pictures a few weeks ago,,, s
t up by them,,,then rode a bike for 3 weeks,,, Now I just have massive respect for both the rider and that gloriously prepared bike,

Totally achievable Alun, I'm very nearly that on LPG, and we all know you lose some direct economy on gas.I've seen 31.5 MPG on petrol cruising on the motorway which is amazing if you think its a 4,000cc V8 and one that was designed in the late 1950's.
Flick the magic economy switch and she jumps to the cost equivalent of 45-50mpg, but best of all she runs, idles and performs way better than when she left the TVR factory 19 years ago.
That's progress
My instinct says I could achieve better than 25 mpg but until I've actually done some testing I'll stay on the side of caution Dave,
Chatting with Jay regards mapping, he said he'd be on it at least 1 day,,, possibly two,,, so the fuel usage sounds about right too,
I realise Doms got cars backed up for mapping right now so I'm trying to give him enough time to get through the list a bit,,,
I can hardly wait but they say good things come to those who wait,,, so here's to a beautiful map and happier running,,,
Davey, so your happy with your upgrade too,,,mines only been in there a few weeks and I'm over the moon with it so far and that's without it even being on the rolling road, just Jay doing his best up and down the busy M6,,, which as Dom pointed out is all bks and I can't do it properly without the road.
Ok I went with Dom and the Mbe, any decent install is a tremendous upgrade compared to what we had.
Nothing wrong withCUX14 but it's all so old and the wiring etc, just to many variables to faff about with when things aren't right. Best 2k I've spent since the day I got the car over 4 years ago and many thousands spent on other areas,,

My cars booked in for 8am tomorrow at Tvr Power / Powers Performance for some mapping tweaks and a fiddle here and there
I drove the car a fair way today,, shunting,, annoying or what,,, with that ironed out I think I'm really happy with the car/ it's spec/ condition,, this should be the icing on the cake so to speak . Fingers crossed .

and masking the shunt on your spec should pose no problem at all

I've been waiting since July..........
Edited by N7GTX on Tuesday 13th October 21:33
I'm only getting mine done so I stop calling
I do need the car at the mo and Dom knew this months ago so he's just keeping his end up
I just hope it all goes to plan, I'm really enjoying driving the car so with the map tweaked it should be a bit of a joy.
I've now covered almost 1,000 miles with the MBE and it's a great improvement, even though its's mapping is limited just to get me started for running in the rebuilt engine. I'm hoping for full remapping next week if poss after I cover another 1,000 miles or so and while I'm unable to drive for a week following a minor knee op.
Glad you're finally getting yours sorted Alun, I have to say I'm very impressed with Jay's work and his helpfulness etc.
