Procharged SS Tach drops to 0 at around 70mph
I recently (end of May) procharged my 2020 Camaro SS auto and for the past month, I have had issues with it. During larger pulls (around 70mph) the tach drops to 0 and the ESC light flashes on the dash. This has happened twice now and each time it has happened the traction control has been turned off. It’s even more strange because it doesn’t happen every pull. When the light flashes and the tach drops, the car lurches (like traction control is kicking on, even though it is supposed to be off) but I can hear that the engine rpm doesn’t decrease. The tach then stays at 0 until I turn the car off for a few minutes, then it runs like nothing happened. Like I said, I haven’t noticed it until recently, because I rarely do pulls, and when I do they are small ones. Also, the car is also not on the procharger tune. I had it dyno tuned and it made 595whp and 505wtq. Has this happened to anyone else before or does anyone have any idea what the issue could be? Thank you in advance!

What are your supporting mods for the procharger? Knowing your full mod list will help the forum find a potential issue.
I dont want to make any guesses until i know more.

My ZL1 started to acted similar one time while on the highway when I stomped on the go pedal. Turned out to be the engine harness or some other wires that were fraying under the engine from what Chevy service said. Would have liked to see where and how they repaired (think just tape and secured the wiring) but the repair was completed before they called me. Good luck!

No supporting mods. Just the p1x stage 2. And I’m glad to hear that fixed your problem! I heard it could possibly be due to grounding but didn’t think it could be that simple. I’ll definitely check into that.

Not yet. If it happens again I will post the code. In the meantime, I think I’ll just baby it and bring it to Chevy when I get the chance to have the harnesses and wires checked and see what they find
