10th Gen Accord Very Odd Behavior After Flash
Posted: Fri Feb 03, 2023 7:48 pm
The FlashPro software is up to date.
The software says to turn off the ignition after I upload a tune. I do that. Nothing else prompts me to turn the car on. I start it and every error possible, to include check engine light is on. It's not the normal drive a few blocks and everything resets. The only way I can get this to turn to normal is to cycle the engine off and on SEVERAL times. Slowly, the errors disappear. Eventually, only the MIL remains on by itself. One last engine ON/OFF/ON cycle and the MIL turns off. Very odd behavior.
One time I flashed the car, it was almost undriveable. Engine wanted to stall and throttle was unresponsive. Had to flash again.
This cannot be normal. FWIW, I have a 2019 Accord 2.0 10AT w/CARB FlashPro
