Yes. Just don’t go wide open throttle with the stock tune (although your combo isn’t radical anyway).

[Jonathan91]

Ok will try it. I replaced my foot pedal and noticed the old one was too soft to press down u like the new one that is firm. I’ll give you guys an update when I install and recheck all the wires

I recommended flashing back to your tuners base file as you stated your tuners base file didn't have the issue and you drove around on it just fine for 200 miles. Flash this file back and see if the issue goes away. If it does not then its not the tune. If it does, then its the tune. With your mods, I don't think running the stock tune is an issue either, just don't do anything other than part throttle driving around. No WOT on the stock tune.

If you're adventurous, you could also look at your tuners files vs your stock file and see if any of the tables relating to throttle and throttle/gear correlation are changed. There is a table that can sometimes be inadvertently copied over from a base file and it has to do with throttle and it can cause erratic and odd throttle behavior. And I am not talking about the Driver Demand tables.

^Agree

Yea I tried flashing the base file which I drive for about 200 miles and the problem is still there. I havent seen the throttle changes other than drivers demand. I’m tired of looking for damaged wires but can’t seem to find any besides the o2 extension wire that was burned through the wire. I’ll be replacing both o2s and the extension tomorrow. Car doesn’t throw any codes. I’ve replaced tb, maf, map sensors. I also replaced foot pedal but I’m waiting for the o2 sensor to get here to turn it on. I’ll post an update tomorrow

[Jonathan91]

What are these intake cam angle and control module voltage? I seen with the log when everything was working fine the angle seemed to be at 0 degrees almost all the time and the voltage at 12.40. With the two logs I did the cam angle is at almost 5 degrees all the time and the voltage at 14.4. Idk maybe it’s nothing

What has GPI said about it?

Did you check the ECU/TCM of the tune for tire height changes due to the slicks that were on it before?

Are you sure the TB's you're using are known good units?
Are you sure the wiring at the TB plug isn't damaged?
Are you sure the wire bundle on the passenger side of the engine isn't touching the headers?

If you put your log in a zip file you can upload it here. I believe you just right click the file and select compress on a Windows OS. Creates a zip file that you can upload.

[Jonathan91]

I havent checked the tire height on the tune. I got the tb at the dealer I checked the wiring at every plug and they seems good. The bundle looks good. I wrapped the whole thing with heat wrap and used a metal zip tie to keep it away from the header, I checked it yesterday. He said “its hard to tell, but the voltage being that low would more likely be an issue than anything to do with the camshaft". So the zip file with the name "wot towards end" is when everything was working fine and the "new compressed" file is the most recent one with the problem, let me know if you guys see something off, thanks, i also attached the file and my last revision with just fbo so you guys can look at. I did see compared with the two he disabled all the misfire under the engine diagnostics. idk what that'll do?

[Jonathan91]

Anyone see something off with my logs? ��

[Megahurtz]

When the throttle is acting up I see the Predicted and Immediate Torque source switching back and forth to Trans/Trans S and Axle/None.

This is indicative that the Transmission is momentarily able to influence the throttle control. It could even be the ABS system kicking in too.

Are you sure that your front wheel to rear wheel ratio isn't too far from stock? If they are, ABS will kick in and tell traction control to do crazy things. You can test this by putting your stock tires back on and seeing if the issue remains. Then you would know for sure which direction to go.

Again, what did GPI say?

Usually the Speedo part in the tune is updated for slicks. Not sure if GM did something in the 2022+ models to make this a problem. We also usually tune the TCM as well so we have never run into this issue even with our cars with 'drag packs' on them.

[Jonathan91]

When I put my stocks back on this problem started. So I put my slicks back on and problem stayed for good. I haven’t emailed gpi regarding the tire size’s. How would I fix this problem if it is abs ? Would I see the light flashing in my dash tho? I’m not sure I they are inflated to the right pressure I think the fronts are barely on 30psi to avoid the abs from turning on when I had my slicks on. I’ll try inflating them all four to the right tire pressure and see if that does anything.

How many miles did you drive with the stock tires


If you turn traction control off does it still do it?

[Jonathan91]

Like for 5 miles then turned back home. I can’t remember if I tried with tc off
