Ive been trying to convert my S2 to efi for a while now but i just cant get thye car to run right it's got a Mk4 cab efi loom, ofab chipped ecu,3 bar map sensor,escort cossie fuel pump,biege injectors, but the car runs at idle fine but just wont rev up at all it just cuts out? so i swapped two wires to the map sensor now the car revs with a bit of a miss but wont tick over can anybody help??

 

fit a FRST loom.

 

weell

with te escort efi loom you may have to change the pins on the ecu to match a frst

does your chip allow the use of a 3bar map sensor?

did you wire the supressor in the loom for the map sensor for the ofab
i was told this is needed
