Hi All,

I swapped in a silly rabbit fuel system with one walbro pump with -6 going all the way back to 1000cc injectors. Flashed the car with a 91oct base flash from Mitch @ Cobb. On a cold start the AFR is around 19.0 then once it warms up it drops to 14.7. After a min or so of idling the AFR starts creeping up and will get really high on bank 2. Any suggestions?

The point of the fuel system upgrade is to run e85 but starting with the 91 file.

Thanks in advance for any suggestions.

its in the tune not the hardware. check the scaling datalog and retune. under closed loop afr will fluctuate quite a bit

 

Ok Thanks. i'll data log again tomorrow and send it to Mitch and have him look over.
