Idle TPS won't go over 21% after MAF fails?

[IDRIVEAG8GT]

Anyone else have this issue? I start the car the TPS is sitting at 25% the MAF fails and it instantly drops to 21% and maxes the idle timing at 31* which nearly causes it to die on a cold start.

Any help/fix? I flashed back to the stock OS, and it performed flawlessly

Here's the tune:

It acts like the throttle blade goes back to a maximum default TPS when the MAF fails. Is there a way to raise the max default up to about 28%? Hopefully this is something that can be added to the beta.

i ran into this before.... in your main spark table in the idle region where is your timing? is it at 31 max?? set it to like 40 or 45 in that region of the main spark table. for some reason that table seems to limit the overall idle timing, which also limits your idle underspeed table.... i ran into this a bunch of times with this OS on c6 z's and g8's.... sorry cant see your tune right now, i am on another laptop

edit: saw your tune, that is your issue... set that area to 40-45 degrees, that will give your idle underspeed table some ceiling to work... like i said ran into this issue with this os a few times...

Yeah but that's not the problem. It shuts the throttle. The car has a decent cam in it, and cold starts it won't idle over 600 rpm because of the throttle blade shutting right after the MAF fails.

I need a fix for the TPS lol. Anything over about 32* idle timing and she starts knocking. Lol.

If you raise the "Max fail" value in the Idle, Airflow tab this should allow more throttle blade area at idle with the MAF failed I think.

If you were a woman I'd make sweet sweet love to you right now.

Lol, you were right on the money. Thank you so much
