I have attached a log showing my success and failure. Here is my outline of it. I am running XP with a Tactrix 2.0 Rev E:
1. Stock ROM - ECUFlash successfully downloads the ROM into memory.
2. Open Vishnu's Stg 1 tune in ROM Raider. Save as to give new checksum.
3. Write ROM to car. Gets an error at the end of writing:
[00:40:52.330] checksum routine start refused.
[00:40:52.330] interface close
4. Try to read ROM:
[00:41:15.794] OBDII communications failed - trying OEM bootloader...
[00:41:15.824] OEM bootloader communications failed.
[00:41:15.834] interface close
5. Power off car. Power on. Try again. Same error.
6. Start engine. Works great. Amazing tuning, Shiv! Freaking amazing. When you hit 4k rpm, VTEC kicks in, yo!
So I drive around. Car works great. Come back to garage.
7. Try to write stock ROM that is still loaded in ECU Flash. Get an error:
[01:10:15.064] writing area 00008000-0013FEFF...
[01:11:50.261] J2534 error [ERR_TIMEOUT].
[01:11:50.261] download transfer failure at address 0012EF00.
[01:11:50.271] interface close
8. Shut off car. Turn back on. Try to start engine. NOTHING. Oh dear.
9. Reflash Stg 1 tune. Get same error:
[01:15:42.655] checksum routine start refused.
10. Shut off. Turn on. Engine starts.
So I have Shiv's tune installed and running. However, I cannot read the ROM nor go back to stock. Ideas?
Thanks!
