I experienced some difficulty in flashing a map to a 2003 WRX with the latest version of ECUFlash and firmware on a Tactrix OpenPort 2.0.
Device Firmware Version: 1.15.4126
EcuFlash Version: 1.44.4247
J2534 API Version: 04.04
J2534 DLL Version: 1.01.4247 Apr 18 2014 16:14:37
While attempting to write (note: test writes were all successful) ECUFlash would present an error saying the programming voltage was out of range, at 13.02v (sometimes 13.04v). I found that many ECUFlash/OpenPort 2 users resolved this issue with the introduction of draw on the battery by turning on the brights and trying to flash until the OpenPort read a low enough voltage. I had this same experience 2 weeks ago on a 2004 WRX and this resolved the problem, the map flashed, and the car is running great. Trying this solution did not work on the 2003 WRX however, when the OpenPort voltage reading got low enough for ECUFlash to write, the multimeter had a reading of less than 10v on the battery and mid-flash the car died with ECUFlash repeatedly displaying "read failed" until the "***DO NOT TURN IGNITION OFF***" dialog popped up and said to retry the flash immediately without turning the ignition off.
The car was parked next to another, so without touching anything in the 2003 WRX, I hooked jumper cables up to another car's battery and attempted the flash again. ECUFlash can still communicate with the ECU but I'm back to the point where I'm getting the "programming voltage out of range" error with a reading of ~13.04v again. When ECUFlash does the map compare before attempting to write and before displaying the voltage error, it shows that all of the CRCs with the exception of 3 all match. (See log paste below).
I'm petrified of turning the ignition off, trying to put draw on the battery again, disconnecting the test connectors or flash block, or disconnecting the OpenPort for fear of bricking the ECU. Right now the car is sitting in my garage with the ignition in the on position, a trickle charger hooked up to the car in "maintain" mode at 3A to prevent the battery from dying again, and my laptop hooked up with sleep mode disabled and ECUFlash open, all to prevent the connection from being lost. It has been sitting this way for 18+ hrs now...
As far as the original voltage issue, I've tried 3 different OpenPort 2 devices, and 3 different laptops...
Does anyone have any suggestions as to how I can successfully finish flashing this map to this vehicle under these conditions?
Thanks in advance for any advice!
