How are you going to downgrade the firmware if you can't connect via serial?

EPROM burner. Obviously thats last resort, after speaking with AEM. I don't think he even has a map saved anymore.

Sucks, what happened that started this? You just connected and got the error out of the blue? I was upgrading the firmware a few years ago with a USB adapter that went fubar and wasted the chip. AEM is good about sending out replacement chips quickly.

I am pretty sure if it is running at all, there is still a cal on it. Not sure on the connectivity issue. Good luck, Mitch.

Right, but if we have to hardflash the chip without being able to connect, won't that delete the cal on the PROM?

i would bet the last time i had it connected was two years minimum. if that counts as out of the blue then yup ha.

not only am i worried about having to buy another one but i dont have a backup cal. yea. weak. means i cant even start it with a new one.

Problem solved. Upgraded AEMPro and it worked on the first try.

Ha. Mitch, I thought you tried 3 different installs of AEMPro? Glad you got it working!

That's only happening when they update the firmware from 1.11 to 1.19. It's something in the cal conversion I think. Just don't update the firmware until you're on the dyno ready to tune?
