Sometimes running VEAnalyze will lean my car out to the point where it stalls
Been running VEAnalyze, and it's been great, but once in a while when i'm tuning with it, it'll just start leaning out my cells. If i'm driving and not watching it, sometimes it'll take a 40 cell down to the teens, and i'll start losing the ability to accelerate.
Any idea what could be causing this? |
I have the same thing. When cruzin at around 5% throttle it'll get really lean like 18-19. Then the car starts sputtering.

Change the authority limits under advanced settings. This way ve analyze live can only change the cell by X or X%. I have mine set to "Maximum cell change of 10" & "Maximum cell change percentage of 10%". Also is your cell change resistance set to low?

Does that happen everywhere in the VE table, or just in the lower row? My experience was that it tended to lean out my 20 kPa row too much, so I manually tuned that and set the min kPa for autotune to like 34 kPa (something a few kPa above your typical idle range) so it won't touch them.
Also, run your cell change resistance on "very hard." |
And make sure you have closed loop off....

What does your target table look like?
