TPS Settings?

[1_bar_of_boost]

On light throttle usually in 1st gear around 1500-2000 rpm, cruising in the car, it will slowly start bucking and getting worse like momentum reaction? The engine isn't smooth at that point? would this be adjustments to the map or tps settings?

This is a difficult thing to explain so if you don't understand its cool...Ill eventually figure it out, just wondering if someone know off top of there head thats all.

thx

Make it richer

i know what you're talking about. i was actually working on that earlier today. +1 on making it richer. my wideband o2 was pinned at 21.7 when it was doing it. VE analysis in megalogviewer fixed it eventually.

Make "it" richer? It, meaning lower TPS or low MAP adjustments richer?

[BabyBlue240]

yeah, if you've got a wideband just put in your target AFRs in the table and let Megalogviewer fix the problem. if you don't, just drive around and see where it is in the VE table that it has the stumble, richen it up there (increase VE numbers) until it goes way.

Cruising has nothing to do with the TPS. Or MAP acceleration, either. Accel enrichment is only active when the throttle is being rapidly opened, the motor likes a little extra gas then. Otherwise, at a steady state it's going off the VE table.

However, the way yours sounds like it settles into a lean condition, the AE might be covering up lean spots in your VE table for a short period.
