it's really uncommon to have issues with these ecms
the vpp voltage has to be in a very narrow range
you never answered me what the ecm voltage is according to the eehack datalog.. connect, go to the tab that says *Main, and look for [IGNVOLTS]
if you're willing to open the case you could probe pin 1 on the eeprom chip an see what the vpp voltage actually is once it's set high. it needs to be 11.4-12.6 volts.
