At idle goes into Accelenrich with no trigger

I recently upgraded to a wideband O2 sensor. So I'm in the process of adjusting/retuning. I keep stalling out at idle so I datalogged. It kicks into Accel enrichment, but I don't see it reaching the threshold, which of course it shouldn't be at idle. I am only using the TP for the accel trigger. It goes way rich and stalls out. I'm using Tunerstudio MS v3.0.03. Im also using megasquirt-II _2920.ini, Monitor_v2.920.abs.s19. I've attached my current tune and 2 datalogs. If you scroll to the end of either datalog you can see where it goes into accelenrich. I can't figure out why????

It may be the trigger event was a bit of noise too quick to register in the log. Where is the TPS grounded?
Also, try using less pulse width at zero TPSdot.

If it was up to me, I would turn off Map Accel entirely........

Its grounded back to the common ground for all my sensors. I'll try using less pulsewidth at zero. Just to better understand what effect will that have?? Ken. Im using only tps for my accelenrich trigger
