i am im in the process of fitting a zvh engine to my f reg rst and have been told that the fuel management chip needs to be changed.

if so what chip would be best? car is F reg so has Bosch system and is not EFI, has been chipped already but unsure what chip it has.

any help much appreciated

 

There isn't a fuel management chip as such in a series 2 (mfi).. you would need a chip though for the spark ecu if you intend to run more than standard boost (no doubt you will).. give any reputable tuner a call for info..
