Ok guys I did more testing. Started pulling wires off and checking to see if the fireware was still corrupting after being turned off and back on. There is only the TPS and crank position sensor wire along with power and ground. Thats all that is hooked up and it still corrupts the fireware. I did find out that it only corrupts when the 420a decoder is selected. When thats off then the firmware does not corrupt. So that makes you think its a problem with the fireware maybe, but ever the 420a decoder worked fine in the house test. Im almost out of ideas, please give me some advice guys.
