ive got a s2 running efi using ofab the loom is from a xr3i efi ive fitted it to my s2 and done the pin changes at the ecu fitted an frst air temp sensor and cut wire 2 at the edis, its got a 165 superchip and beige injectors.

the problem ive got is when it starts it runs like a bag of $h!t missfireing and chugging its fueling up massively smoking black and grey smoke it stinks of fuel dont no what to do, it was doing the same when it was running as an ofac setup if i disconected the map sensor it would idle and rev but now it just dies

any help will be great

I thought you only use beige injectors with 195 chip i am no brain box when it comes to this but try bule ones they go with 165 chip may be thats why it could be over fueling

the beige injectors need to be used with the 195 chip yes but ive done this conversion 3 times on 3 cars now using standard injectors and no chip,all 3 of them have overfueled when ticking over,then when you try driving it and it starts to come on boost it just starts to kick back and not want to drive,the only way i got this sorted was by running the brown wire that went to pin 46 on the ecu to the negative on the battery instead,i want to tidy the wiring up so want to wire everything up correctly but cant figure the wiring out as everything seems to be in the correct positions
