no dice on the populated reversion and dynamic gain tables. Made my car very jerky and the lean spot is still there. I even tried just the reversion table, but that didn't work either. The short log below is with both the reversion and dyn. gain tables populated with ZL1 values. If you go to 4:38 you can the populated tables actually gave me MORE lean spots instead of getting rid of them.....maybe there's something to that. You can see the three humps

Hmm, does seem your spikes are happening more often, 1600, 2200 and 2500rpms. Not only that but the spikes happen are few hundred rpms different now sometimes. I see it at 2700 rpms instead of 2500rpms on the end of the log. This is the 1st time ive seen a change from a change in the tune.

Scott- Compare the files I sent you from 6.22 and compare to 5.31. Those are the most recent changes that made the difference for me.
Sorry guys. I've changed so many things from stock that it wouldn't be worth it to post the tune I am using.
Jay- PM me your email addy and I can send you the tune if you want to see it.

did this ever get solved? if not pm me.
I have an 09 CTSV, I dont have any lean issues around 2500. Maybe you can find what youre looking for in my tune, i'll post it when i get to work. Also, if you see something that you believe to be wrong, please dont hesitate to let me know.

I'm sure I have a WOT pull somewhere. I'm gonna throw it on the dyno tomorrow and I'll be able to grab one for you.Attachment 134461
No problem buddy, hopefully it'll help

I am guessing you will have the lean spot since you have ID850 injectors. My theory is that the spray pattern of the factory LSA injectors is different than other factory (and aftermarket) fuel injector spray patterns. Presumably this could be overcome with a transient fueling correction...but...this one hasn't been solved yet, so who knows.
A standard approach will give you standard results.
