ecu chip upgrade or not ?

[bone]

hi,can anyone tell me is it worth £400 plus to fit a mark adams chip to my 400hc ,is there much difference to the standard cars performance or am i better looking elsewhere for gains?,thanks.

Haven't used a Mark Adams chip, just went straight to an Emerald unit fitted by Dave Walker http://www.emeraldm3d.com serious performance gains and a lot lot smoother ride. Better fuel ecomomy also.

Worth a day out in Norfolk too right!!!

The Emerald is a top product and I also went straight to it rather than chipping the old Lucas.

But AFAIK, Emerald doesn’t do a fitting service. Try Trackcar for supply, fit and mapping. Emerald supply for DIY installation, then map it for you.

The extra gains of mapped ignition make it a far better bet.

I had Mark upgrade my car recently to one of his Tornado chips.

Not a lot of power gained (about 7%) but much smoother and more reliable idle and smoother low speed driving.

It was also a very interesting few hours and Mark was very nice.

Probably is going to be more dramatic if

a) your car is really out of tune
b) you have made some serious mods

but worth it just in terms of drivability improvements

You can do some fuel trimming with a variable fuel pressure regulator for much less than a chip. TVR have already remapped the cars, so further gains will be small.

The main benefit of Mark setting up a Tornado is when you have had a lot of induction work done to the engine. This is what i did with my 500. After it was remapped the engine ran very sweet and returned better mpg than the 400 engine before!

Emerald do a fabulous fitting service - thus my reference to my day in Norfolk and who better to fit your emerald than Dave Walker himself. Anything else just has to be compromise shirley..

Never even considered an actual measurement! My point was purely based as a comparison. Considering when i drive the TVR it is because i want to go for a proper drive. No mercy on the fuel guage. The remapped 500 uses no more fuel than the 400. And I'm going a whole lot quicker!

I felt the MA chip was the route for me since I bought a 500 short engine, loads of induction mods and reused all the old 400 EFI stuff. This then needed completely remapping to suit the new engine.
