Pig Rich during and just after wot shift
So I posted this over in the SST forum first, then had it moved to the X tuning section... still not much feedback from others. Wanting to see if anyone else has noticed very rich mixtures during wot shifts and just after....... This what I have been feeling as a bit of hesitation just after the shift..

Trying to figure out if this is something unique to my car or if all the stock turbo or even x turbo swapped ralliarts tend to do this.

Yeah mine does this. I seem to recall having logged this a while back, even caused some mild knock when the change to rich was extreme (like more than 1.5 afr)

I'm gonna start logging IPW and see if that sheds any light on the situation.

Is there any light knock associated with that drop from 11.65 to 10.43, down to 10.00 (which is probably lower, I'm assuming this is just like my Pro Sport with a range of 10-20afr)?

No knock that i have ever logged, but yes the wideband is a 10 - 20 range (PLX). The wideband does have some minor voltage output variation (fixing that this weekend I hope), but the rich dips are for sure pegging the wideband at 10:1 or a second or so.
