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!

This is strange...

I will attempt to read my ECU afterwork today. I am currently running Shiv's OFT E85 map on my car,

I have had success flashing and running the car with and without letting ECUflash correct the checksum error.

[01:11:50.261] J2534 error [ERR_TIMEOUT].
[01:11:50.261] download transfer failure at address 0012EF00.
This is the same errors I was getting that left me immobile for weeks, but it would give this error regardless of what I tried to flash, Stock, OFT stage 1, made no difference. I still get this error on occasion, but it wll retry several times now before terminating the flash...It has completely failed to flash 2X but subsequent attempts have allowed success...let me tell you, there was severe pucker factor while parked at McDonalds uploading E85 maps for the first time...and I kept getting failures...I was wigging out bad, then i got a clean flash and all was unicorns and pixie dust and stuff...
