Check Engine Light, Fuel related
Alright, my friends car tripped a CEL. It's fuel related and it's pretty wierd. It happens like 5 seconds AFTER boost. Car runs fine off boost, like if he keeps his foot at 10% steady throttle all the way to redline and keeps the engine under vacuum.
ALSO, it doesn't happen all the time. Kinda wierd....
I'm thinking he may be running a little rich. 370 ccs with S-AFC set at -35% at idle and steadily increasing to -25% @8K at low throttle and -35% at idle steadily increasing to -20% @ 8K at high throttle...
He has a 12:1 FMU and 370 ccs and an inline fuel pump after the fuel filter.
Even with a -35% @ idle, his air/fuel is still pegged at rich. Should it be leaned out even more?
