I have a Lotus Esprit Turbo, Its bloody quick but its completely standard. Its been hardly used for the last 11 years, now I intend to use it as a daily drive. Worth Remapping?
Possibly, but i'd be worried about the extra stress it puts on components. With a car so old, i'd be making sure I can get hold of a replacement gearbox / diff / engine! Just in case the worst happens.

Afraid I don't know a huge amount about these. How mappable are they? I presume they are EFI of some sort? I suspect a piggy back upgrade might be possible or you might be looking at replacing the ECU to something aftermarket.That said, as a long term investment it's well worth researching. Suspect Megasquirt or Emerald could be adapted.
I'd also want to check out what sort of limits the engine and drivetrain can take. I don't know if Lotus changed them for the V8's, if not then it's just a matter of not nuking the motor.

Really enjoying this topic,
Iv been toying with having my 3.0TDI A5 mapped for a while, Promises of up to 50bhp and 60lbft increases.
it fast enough as it is, but maybe afterwards it will somewhere close to a 335D
Nah, I heard Chuck Norris test drove one (335D , remapped) and got out white as a sheet, crying like a baby, he got on his Turbocharged Hayabusa and left with his tail between his legs.Iv been toying with having my 3.0TDI A5 mapped for a while, Promises of up to 50bhp and 60lbft increases.

Rather more than just a remap but I had my old CL600 'done' by Kleeman with their K3 stage tuning pack and the difference was shall we say noticeable!
From 493bhp - 700+ and from 800nm - circa 1200nm
I do believe a fair chunk of that was down to the ECU remap the rest being improved airflow, cooling and decat etc.

I had a 1.6 Focus remapped, waste of money, did nothing for the car but that was a good few years ago so you live and learn. I tried so hard to find a difference, but it just wasn't there. It was a load of crap.
Had my MG ZR TD remapped when I had it, massive difference, took it up to 160bhp and about 250IB FT (clutch limited)...best thing it do just do your research on how well your engine responds to these things, obviously turbos generally well as it can increase boost, or VTEC can be bought in earlier on Hondas.
Friends Ibiza TD is on a stage 2 remap with 190bhp and 380IB FT. He went for a torque map, not a HP map and it flys, can out pull a stock Focus RS.

I understand a remap on how it is sold and having had a few in my time there are a couple of caveats.
MPG increased, this is fallacy in a lot of cases as the way the car works out mpg is sometimes convoluted and complexly but a lot of remaps will inject more fuel, where as the car still thinks it is the less qty, thus showing a increase in mpg as you now will have less throttle higher up the range. (the placebo effect works well here)
Another is the bhp claim, even tested on rolling roads (which also vary between 0 -10 %) this figure is meaningless as you will have increased 'fueling' and over boost but to accurately know this, would require a lot more than the 200-300 pounds some will spend.
as long as you go in with eyes open then fair enough. I also have some software where i can tailor my own maps, which is quite fun..

Put a remap on my 123d in the UK after a lot of advice and getting used to the standard car. Took a good diesel to a level that i never thought possible, simply stunning through the gears. 400GBP from a place in/near birmingham, really nice fella.
On the right car definitely worth doing.

errrr not EFI, twin weber carb.That said, as a long term investment it's well worth researching. Suspect Megasquirt or Emerald could be adapted.

the car has only done 60k from new, runs on a renault gearbox so that would be easy enough to replace. I am thinking of fitting a stainless exhaust rather than old rotty one so a remap for the difference in back pressure and a possible slight power increase. I dont want a huge power increase as the car is already lightning fast. Might of already been done, I havent driven any others to compare though
also the drivetrain and the engine are the same as the SE which has a different chip and is chargecooled. That puts out an extra 60 horses or so and I know of people that have increased that with no issues. Obviously the chargecooling makes a difference but how much?

Had a nice deal at JKM in Portsmouth who remapped my Mk.1 Skoda Octy VRS.
A power increase was obviously desireable, but I was more interested in getting rid of an annoying flatspot just off a closed throttle, and the fact that the engine seemed to get wheezy at anything over 5,000rpm.
They were doing a deal on 'Revo' maps at the time - £199. As I was expecting to pay the usual price of £299, I spent the extra £100 I saved
on a Pipercross replacement filter and a nice shiny recirculating alloy dump valve.
The map and the other little mods got rid of the flatspot, and now the engine also pulls like a train right to the rev limiter. They tell me it takes the total BHP from 180 to around 200 too - and it certainly feels like it has, although I didn't pay for a rolling road session to confirm it.
But altogether, I am delighted with the changes for 200 quid. Money well spent IMHO. And 20,000 miles later, the car's never been running so good.

I'd like to get my Golf Editon 30 remapped, but I can't see how it will handle the claimed 300bhp as it struggles enough with the 230bhp it has at the moment.
The simple answer is to not press the throttle to the floor...?You'll really enjoy the added go when overtaking, slip roads etc.

what did you get out if I may ask ? got a 9-3 tid auto and thinking to get it done up...
I went from 150bhp to 212bhp (torque 236 to 327)This was on a '55 plate car. CelticTuning did the work.
Apart from the £1000 bill for the Flywheel, I loved the remap. Completely transformed the car and I'd do it all again.
Still gets around 55mpg without trying too.

Think like a manufacturer. If you are upping the power, perhaps you should modify other parts to suit.If you up it to 300bhp, it might be worth getting better tyres and/or a LSD/ATB:

Then you would have more power and a drivetrain which can deploy 300bhp better.
