But your engine is not so radical that it should need these modifications. Think about a new driver who keeps stalling the truck when letting the clutch out on hills. The new driver blames the hills while the experienced driver sees it differently. You could set out to level all the hills but is that really the right approach?Yeah, being able to do this would solve my problem and still allow CL in most situations.
Those can be tough areas to address. What do the logs show? Rich or lean operation?My issues all center around decel, idle, and just off idle accel.
IIRC the logs should still show O2 readings. And you should be able to confirm OL operation by monitoring CL flag.Now I have a new problem. Not sure if it is connected with running in OL only or if it's something else.
Not really. Most likely your cold enrichment plus power enrichment is adding enough fuel to cover an incorrect VE table. But the problem could also be spark timing, or a combination of spark and fuel.But when it's cold it'll do the same scenario fine. Weird?
I try to tune warm steady state conditions first then move to warm transitions (accel/decel) and finally the cold start. That doesn't mean I ignore other issues, but I don't waste time trying to make them perfect. The code is set up so the VE and main spark tables are the baseline for most other conditions. If these are not right then any attempt to tune anything else usually results in problems showing up elsewhere in the cal.
