I have an area of the VE table around 3700rpm that typically when steady state tuned always wants less fuel. When taking off from a stop as it sweeps through that area of the map in first and second gear so fairly quickly, it will always lean out to around that spot, around 15.5 AFR. If I add to that area that lean spot will go way when running through gears, but then stead state it will be too rich 13.6 AFR and EGO correction will fix it. I have generally just been splitting the difference so it doesn't go as lean passing through and has to correct a bit less at cruise. Anyone have any thoughts?
This would be where you'd use acceleration enrichment to solve the problem.
I had considered this also, but since typically the throttle is not moving rapidly while just running through gears in traffic, if anything it may be even maintaining the same throttle angle or slightly declining shouldn't it not be using any accel enrichment anyways? Taking off from the light it obviously kicks in getting up to speed but as I move through gears like maybe second and third the throttle movements are much less than takeoff. Sometimes just hanging out around the 20-30 percent tps range.
