Post by shimei »

Return to stock before anything else and see if the problem persists. Take care to power off after the upload finishes. Drive a mile or two and see if the sub system error clear.

If you do take the vehicle to the dealer, which I don't recommend, then you absolutely must return the ECU to stock and unlock the FlashPro.

Already tried returning the ECU to stock and the errors persist. It acts like the flash never stops there's no clear indication of when it is done. Some major differences from the previous version 3.4 to 3.6. Just about every system rolls through the dash as erroring. Not even the economy mode will engage now.

Second time, flashed to stock but this time went for longer drive. The errors went away. When I returned I was able to reflash with my calibration. Problem resolved. Thanks for your support!

Good. Once you get those sub system errors, subsequent reflashes will still show then unless they are cleared.
