Silly question :-)
If you get a failed upload (Code 0x27 Step 7 Address 0x000000), is the previous calibration still intact?
Or does the new calibration half-install, and you end up with a bit of the new calibration and a bit of the old calibration?
(The ECU status has the green check, it's not in recovery mode).
Does a failed upload mean the previous calibration is intact?
Re: Does a failed upload mean the previous calibration is intact?
Old calibration is still in the ECU. Step 7 usually means that you just need to power cycle the ignition. Or the ECU has been previously reflashed by someone who has changed the security keys.
