How much fuel split is acceptable?
I just recently installed my LT headers and got the car back on the road after a spring/shock swap...
I was watching my short term fuel trims in Autotap and noticed that when all plugs are firing right there is a slight split from one bank to the other.
They'll be within say 2-3% of each other, with bank one almost always being higher than bank 2...
And my long term fuel trims haven't moved any... they're odd...
-.8% for bank 1
-1% for bank 2
Always, regardless of fuel cell or TPS, RPM or MPH...
