1780lly steel forged big valve head straight thru stainless steel pipe stage 2 hybrid new injectors new 488 pump new cossy fuel pump harness pulled good MFI figures but ran super lean and running over fuel low down , just need a bit help in choosing what to do haven't got a clue about stand alone or efi conversion i have spent a lot on the car already so funds are low whats the cheapest and easiest thing to do

 

Didn't the RR place give you any opinions?

 

yeah told me to go EFI ,,, but i really like the idea of having a high BHP mfi car , i have just been back ti it today and found it running lumpy and i found that the ACT sensor was taking in air in the plenum chamber after i re sealed it it ran real nice , would this make my car run lean at the top end ?

 

dont think you would get much more out it on MFI i had the same problem loads of fuel down low and and on the limit top end.
i will be going standalone management.

 

Either go cossie management and pic up all the bits as cheap as poss or spend more on newer software as things have moved on since the cossie stuff was created.
MFI is too prone to issues, last thing you want is to melt your engine

 

Maybe wrong chip Neil

 

hey i have another ecu i can try ...thanks bud
