Hi guys I have fitted a new vr6 engine and transferred all performance parts of my old one and fitted S2 fuel injectors etc .but it smells like its over fuelling. The ecu was already remapped. I have phoned about 6 different rolling road pleases and nobody seems to do chip tuning any more .because it's easy though a obd port Can any one point me in the right direction or and other ways to sort it Thanks Lee
You don't need S2 injectors if you are naturally aspirated. Just use FPR. If OBD1 car you can use removable chip from socket. Example techtonics tuning. I have one for coilpack ECU.
Because S2 injectors are larger than the standard VR6 12v items. I would suggest refitting the correct injectors for the AAA engine. The ECU can be remapped, but it is a slow process and most places have moved on from DIP28 chips and PLCC44 eproms. In your case, it is just a case of you used the wring hardware on the vehicle. Regards.
Am I best pulling them out and finding standard fuel injectors then mate . It's a obd2 coilpack I have .is that the company you got it from
I just gave you solution. Mapped 12v cars be it M2.7, M2.9.1 or M3.8.1 ECUs, with stock or cammed engines, do not need larger injectors than stock.
