Hi lads I'm just after picking up a fd3s and a problem I have now is when the engine hits 69 degrees my revs start jumping from 1000 rpm to over 2000rpm and the injector duty jumps up and down from 0 to 10 percent and when I'm driving every thing is perfect drives very well but when I put my foot on brake to slow down the injector jury stays at 0...I've search and can't find a answer to this

Just to let ye know car is totally stock apart from Pfc and map

Any ideas?


Thanks

 

it should go to zero on decel.

the temp correlation would make me want to look at the coolant temp correction maps. check out the power fc section of the forum for more info

 

Sounds like the wrong wires were cut when the pfc was installed.
