Ecu upgrade, what to expect ?
Discussion
it's not a bad idea 
thats a nice kinda dont need to look for the power motor enjoy it 
even before I took it back for mapping Simon, I kept thinking,, this engine seems really sweet, better than ever, just the sound of it on tick over etc.
Yes it's time to leave it alone to do its thing,,,,,
I like the fact it still looks fairly standard in the engine bay,
I might do the odd track day ( funds permitting) but it's a road car and after rather to long,, yesterday's drive with the new softer shocks etc, the cars going in the direction I want and it feels really good,,
Some Audi got to close to my Arse last night,, a few seconds later it was gone,, I was chuckling like a kid,
4th and 5th gear it's so much faster than standard!

Sat in the que at Doms awaiting an MBE if he has any left! Boy this modding malarkey gets expensive.
No doubt I will feel better when Dom has sorted it
You in the right place for proper workmanship......and proper bills!!!!!!!!!!!!!!!!!!!No doubt I will feel better when Dom has sorted it
Edited to add: Proper workmanship is well worth paying for ! Can't fault the overall service I've had from Dom and his lads, sometimes he even makes you a mug of tea !!!!!

Just a final update,,,,,
I've had the car back a couple of days now,,
As with most if not all our cars mine has always suffered from a loose transmission system,,,, always had to ride clutch to negate shunting etc,
the first obvious thing is how I can run along in 4th at say 30mph and transmission stays quiet, I've saved the price of some CV joints already
The driving experience is very different to before, much much easier to drive around town, I estimate its at least 30% less effort to keep everything taught.
Throttle response is pin point accurate, changing gear is a joy.
Starting the engine from cold or hot it's consistent
The power and torque feel tremendous and the engines manners are now impeccable,,,
Sheel another local Tvr owner had a drive of it,,, first time I'd been in the passenger seat,,,
We both enjoyed that drive I reckon, I really enjoyed how the car felt as a passenger,
As others so rightly have mentioned, I now have a very sorted package, I hope to just run the car awhile now and enjoy it, a couple of years down the line the money it cost will be a memory but the cars ability should not alter to much.
I've done it at last,,,,got the car to a point I believe in its reliability,,,
That my friends is a priceless feeling and one I find hard to explain, it's a Tvr,,, common consensus tells us it's a shed,,,,
With help from folk on here who share knowledge and the talents of a few people who worked on my car, namely Tvr Power,,, yes it's expensive but then so is fuel, tyres, oil, clutches and transmission components,,
The Ecu install has many benefits and knock on effects that already seem to far out way the cost.
The install is very neat and tidy,
A combination of new ACT intake pipe and Jays mapping has given it a power hike for sure so its just a win win situation,
Whatever Ecu you might be considering I now consider it the first and possibly the most important Mod or addition to your car,,
You simply remove, wiring, alarm, starter circuit, and in my case immobiliser issues in one hit, oh I've already stopped thinking about stepper motors,,, priceless.

Al been having trouble signing in....pleasure driving yours yesterday. Turbine smooth and very refined. So takes the hard work out of driving these when they perform like this, leave it alone now and enjoy .........get mine up and running with the canems and we can put the two together and see how they do!!
Now bugger off to France in it and fullfill your next dream!!
Sheel aka rich

yes Rich, they'd be neck and neck. I've just had the most enjoyable drive this afternoon since I owned my Tvr,I've been adjusting the new Ptotech duel adjuster shocks,, their magic,,, transformed the slow speed driving and no nodding dog syndrome at speed, country lanes are a breeze,
I've managed to get the rears to be soft enough to be compliant yet I've wound the re bound up a tad and now the car doesn't bounce, the front feels totally planted and stable at all times,,,
I've noticed they have a good few more windes of steel than my old shocks, thinner steel,,,, so they react to the pot hole type bumps far quicker and less harsh,
If this experiment in softer springs hadn't worked I would have said so,, a bit like the Mbe, the shocks are so much better now,,
The two things that I feel ruined my pleasure of the car namely, shunting and crap road holding, I've removed them both,, what a result. I thought the shocks would feel about the same as say GGP's (old spec)but with more control of the rebound rate, but in fact they are far more compliant yet firm, they do exactly as it says on the tin,,,
I'm well impressed with them

This modding malarkey is mega expensive. My Aston was cheaper than this! Mine is still at Dom's being mapped (waited since July for this!) and now he's found the exhaust manifolds are both split in the middle. Monday he's fitting some ACT ones that he has in stock so goodbye to another £1,000. I just hope this is the last set-back.... Boy this modding malarkey gets expensive.

I'm about to start poking about trying to sort my over fuelling issue.
Anything that's bust or needs fettling that gonna cost over a few hundred quid and I'm next in line for one of Jason's MBEs.
I don't see the point of paying, say £500, to get my old CUX fixed if then the dizzy blows up 6 months later and then the AFM 6 months after that.

Another +1 for Powers, the MBE 9A9 and Jay's patience and considerable talent as a mapper. Thoroughly nice bloke too. We got Kate back last week after the intercooler to complement the SC kit (the water injection proved inadequate on its own which to be honest was always going to be the case). Kate is smooth, linear, well mannered and has acceleration which can only be described as savage if you boot the throttle. 456bhp, 455lbs of torque and drives like a learner car if you want her to. Glorious. Thanks Dom and Jay, been a long process (only just avoided the ''journey' word beloved of reality shows, phew) but well worth it in the end. Like Alun, I do believe we now have our car exactly how we like. Only taken four years and god knows how much stress but definitely worth it. Beware all who set foot on the slippery slope of modifying though, it's not easy and most certainly not cheap.
Ps nice looking car you have there Alun by the way, yours was on the rollers the day I went down to bring Kate home.
Pps Good luck Richard, you're in for a treat and should benefit from Jay's experience on Kate (I believe the first Chim to get the 9A9 so a bit of a development car).

That is insane! How on earth do you get that power from an SC 4.6? Have you got the graph to hand, I would love to see what the torque looks like.MPoxon said:

Hi, I've revised the figures down slightly to 452bhp and about 451lbs to stay in line with the 18% transmission losses mentioned elsewhere on this thread (I was working on 19% following a conversation with Jay about how conservative their 15% is; Mark Adams uses 24%). To be honest it's academic, the car feels immense in any gear yet is so smooth and manageable. I have found the graph now and tomorrow will attempt to get a decent photo of it in order to post it on here. As for how it's achieved, only Dom knows what happens when he disappears into his machine shop and he's not saying. But look at the impressive power he got from Alun's fairly standard 450 via MBE, they know what they're doing. I've seen our graph overlaid on that of the fabled 5.0 SC owned by a certain J Dodger (not rebuilt by Dom, just measured on his dyno) and there's very little difference. Even Dom and Jay were taken aback by the end product. What surprises me more than anything is that we're still only running half bar, not that much really. Sincere apologies to Alun for the thread hijack by the way, I only posted to reinforce the point that while Powers may not be cheap they do understand our V8's. No apologies nessasary Mark, yes please put up your gragh,,
I can't agree with you more re Jays mapping,,listen to my engine and it's smooth as a smooth thing, so Doms not bad at engine building either,,
I know this isn't physically possible but driving my car yesterday the mapping just seems to get better by the minute,
I now consider my car to be far better than the car Tvr produced, they did what they did with what they had and that was some 20 odd years ago,, to have such a glorious engine managed in such a complete way is like owning a Porsche, total belief and security in the engineering,,, as everyone always mentions Dom charges for the work,,, in line with any one stop engineering/car management shop really,
Ok to save a fortune you do it yourself,,
Garage, tools, skills, countless spare hours to complete, what if things don't work properly, you may need more tech support, extra mapping sessions,,, what's a rolling road like Doms cost,,,,
Trailer costs, fuel and it all adds up,,,
I've seen Sheels car in bits,,, he's doing an Ecu install, moved battery and fuse box etc, stripped interior for re fit,,, Rich is an experienced engineer with an abundance of skills, technically he's ahead of the car,,,
But by eck it's a big old job,
Seeing Rich pull and replace wiring loom etc,,,he's doing a wonderful job, looking at my install,,,,it's a lovely job,,,
There's a lot of work involved,,, with what a new Ecu brings you in benefits I'm now considering the cost as a fair deal,,
Fit and forget but feel the difference every occasion you drive!!!
Having looked into it, agonised over which Ecu to use etc, one conclusion I've come to is there's at least three kits available
Mbe, Canams, Emerald etc,,they all would have given me the same results.
