Chips in a OBDII PCM?

[JeepsAndGuns]

You guys are going to keep this up untill you get it and then I am going to want to swap to a 411 and CNP ignition....lol

I'm sure this is a dumb idea but what about leaving the chip in place on the board but solder the Moates solder-on header directly to the pins on the chip. You could plug a ribbon in on the PCM side and then into your chip burner if you got another solder-on header. Not sure how the burner might affect the PCM circuit board though.

you stated the issue: powering up the PROM will power up the rest of the board, and the 68332 won't want to sit there doing nothing....

maybe if it's reset line was being dealt with at the same time(to prevent it from trying to read and execute instructions), it might work?

[Scott68B]

I'm suggesting powering down the PCM while burning the chip.

[RobertISaar]

well, that's a problem.... to burn the chip, you have to power it up first. the circuit that the PROM uses for power is more than likely the same +5V circuit that the 68332 uses. so applying power to it will power up the 68332 as well.

might be able to cut the trace and perhaps install a switch to only allow the PROM to be powered and in the other position, allow power to everything else that uses it.

Then there's a new flash cable coming out for around $200...

[RobertISaar]

one already exists for ~$300, though it does have restrictions as to how it's used.

$200 with no licensing would get a LOT more people in the game.
