I bought the Flashcal tuner after changing my gears. Today I stopped at a busy intersection so the vehicle turns off due to ESS, I release the clutch and at this point the vehicle should turn back on but it does’t. I keep pressing the Turn on button and nothing, all of this while I’m blocking traffic. Finally after about a minute the vehicle turns on with the check engine light on. I get home run the scan with Flashcal and get the following codes:

U0432, P080A, U0010.

I tried to unmarry/return the Flashcal to stock but the device fails anytime.

I go for a drive again to see if it will happen again sure thing it does. I turn off the ESS and doesn’t replicate the issue, so seems to be an issue when the ESS kicks in.

Anyone experience any such issues?
