Hi all I have a M plate 94 850 auto T5. It breaks up badly under acceleration with the modded ecu. I have managed to get a std ecu fitted and it runs perfectly. Do you think it's the chip or is it the ecu it's located in. Any response would be great as I really don't want to waste money having it removed and transferred to a new unit only to find out I wasted my time.

Thanked 295 Times in 174 PostsIt's more likely to be an ignition related misfire, cap, leads and rotor arm are most likely.

Thanked 0 Times in 0 PostsHi Tim yep that's what I thought but I have replaced everything. Plugs,leads,cap,rotar arm,coil pack & even the fuel pump and filter. So I thought it could be the ecu or possibly the map on the chip has somehow failed, if that can happen over time. Perhaps even a cracked circuit board. Would be good if I had another car to try it in.

Thanked 1,393 Times in 1,068 PostsIt's commonplace that a remap or chipped ECU will often unearth hidden gremlins on a stock car.
Assuming you carried out a full 'Stage 0' before you added the chipped ECU??
......if not, you should remove and refit the stock ECU and then complete a full 'Stage 0'. Then you'll be in the best place to start modding.2014 V60 Polestar 6spd Auto :: Polestar map peak boost 17.4psi :: IPD 3" DP + 150cel :: Polestar 2.5" exhaust :: Paddle Shift Geartronic :: Black glass :: Maxton Splitter :: K+N Filter :: IPD Aluminium Top engine mount :: Brembo 6 pots :: 20" Polestar rims :: Brembo 371mm floating discs :: Sensus RTi + DAB + BT + WIFi :: D3S XENARC 6000k Active bending headlights

Thanked 511 Times in 367 Postsit wouldnt hurt to replace all vacuum lines too as the PCV, the fuel pressure regulator and the turbo wastegate work off the vacuum

Thanked 1,393 Times in 1,068 PostsSo the receipt from RICA states they carried out a 'stage 0', I find that hard to believe! Originally Posted by Storm1n
