Mine does it no matter if it is maf only, vve only or blended
On a side note- Mine only does it in Manual TUDU mode. I'll post a screenshot of my VVE histo later tonight.

Yeah mine does it in SD, MAF only or Blended. I have not tried to dial in VVE while blended though. Maybe that will help work around the issue but I dont think it will in my case. I have tossed an additional 5-15% fuel in that RPM range with the VVE table and it still spikes.
Okay what is that, lol.
My honda buddy said he has an easy fix for it. Go Haltech, haha.
beat me to it...lol
I think TUTD (Tap Up/ Tap Down)
damn...definitely feel stupid now...lmao.
Dont feel bad, us manual guys are superior haha.
It's "manual" mode of an automatic - interesting as y'alls are manuals doing it and his only does it in manual mode....

so it's perfection fine with the trans shifting on it's own???
This was actually why I had mentioned earlier in the thread I was waiting to hear back from him - the log he had sent me then didn't have it in it. Think the transmission was shifting how it was designed then.

Damn, yet another variable in this problem
In normal driving mode the trans shifts fine and no stumble. Go to manual mode (tap up, tap down) it stumbles.

Hmm, that is strange indeed. Maybe I do need to go to a standalone! But that always brings along a lot of other issues.

There's got to be a solution to the problem via hptuners. I don't think you need to go standalone. I'm just baffled by the amount of ctsv that have been tuned that NO ONE is sharing a solution to this problem. Either that or they want to keep it a secret
I really hope the tuner I reached out gets back to me. I even told him I would toss him some cash for his trouble. He is probably the most popular remote tuner on most of the facebook groups for GM LSA's. Im sure he is on here also. But guessing he is just super busy.

Cool, let us know if you get anywhere. thanks. I remember asking Pat G about this problem a few years ago and he mentioned that my "coeffcients" have to be tuned. Now I'm not sure if he was referring to VVE coeffcients or the prediction coefficients. From what I've read though the prediction coefficients can't be tuned.
