going lean during shifting
I'm getting a stumble/backfire under load after a shift, especially around cold start. I've read this is a known(?) tip-in issue...At operating temps (180), it's goes away.
Basically, when I press the clutch pedal, A/F goes to 17:1, and when I engage it under good load, I get a stumble.and then the A/F eventually goes back to normal 12:1-15:1). This is on a t4m0 eec with an LMAF stock curve, and 60# inj using Ford's advertised slopes/breakpoint.
I've changed the VE and turned off tip-in, and even clocked the MAF, but just can't get rid of this problem. Any ideas? Do I need to adj the accel pump tables or HEGO tables (stock EGO locations)?
