So i've been working on getting my boost spikes when i upshift and just to try if it had an effect on that i did a few runs in S-Sport found something that i can't explain (i don't really drive in S-Sport often so i never really noticed before...).
When i upshift the AFR takes a nose dive to the rich side and the most interesting part to me is that it only happens in S-Sport mode. I have tried to set the "max rich clip" table to my target AFR above 171* but it did not help.
Anyone seen this before?

 

I forgot to mention that the AFR stays rich for like 1-2 seconds and then it just jumps back to target AFR. This is the same log with INJ duty to better show what's going on.
Also, INJ duty jumps up before the upshift...

 

There is a lower bound fuel map, just like the lower bound timing map(s).

 

Is limiting the lower bound fuel map the way to fix the problem or could there be an underlying issue with the tune or car etc?

 

I changed the table that razorlab is referring to and it did fix the problem.
