cosworth it

Hi there

Can anyone help me???
iv got a sapphire cossy 4x4 iv just uprated to dark greens and got the chip to go with them. the car starts up and idles fine but when you rev it qwickly it spluters through the rev rang but if you build the revs up slowly it fine. I think its over fueling. iv put top noch plugs in and it made no diffrance. please help me.

What map sensor you got on? maybe need a 3 bar

Check with the maker of the chip what other changes you need, i.e. map-sensor, fuel pressure, etc.

iv got a 3 bar map sensor on the way. so with a bit of luck that willl sort it out.

Most setups for dark greens will need a 3bar map!

Surely the chips instructions tell you what map sensor, fuel pressure, co and plug gaps etc you need to be running?
