rich spike?
hey guys when i take off from a dead stop wheather its a hard or light take off, i alway get a rich spike at first, i know i cant completely get rid of it, but i would like to reduce it, at time the afr will to to 8-9 AFR on my wideband setup. From what i understand i have to adjust the table Accel Enrich VS. Differential TPS. Would i increase or decrease this table?

depending on exactly how the rich spike goes, it could be in the AEvsTPS or the AEvsMAP table. you will want to reduce it.
Also, if it only does it when you put it to the floor, you only need to take some AE out of the high delta TPS or delta MAP sections of those tables.
Hope that helps. AE on our cars is a real pain to tune.
