Ok RS autosport went through it so that explains why some things are different than when I built it. I wasnt saying it wasnt mine just that its been altered.

Tell you what, send it back to me, let me install it into my car and fire it up. I wouldn't charge you for it so dont worry about that.

The problem has existed ever before you sent it to rodney? That means they are putting it on a Stim and its working fine for them, IF they are paying attention to what it is really doing. The V2.2 board is semi failsafe. Its not likely a ground issue on the board. I want to try swapping out the ECU chip as well if it does do it for me.

I dont understand why you cant load the 024 firmware. You are jumpering the bootloader correct? Its possible your USB adapter is the problem and the code isnt getting loaded correctly. Do you have a desktop with a serial you can try?
