All around good news today. I got my jeep back from the shop. Plugged in the ECU I just socketed and it fired right up! Looks like the SBEC-II is alive and well!
I also got my rom burner in the mail today. It's old school and uses a parallel port. Luckily I have a cache of old computers and got it working and dumped the eprom file from the ecu I socketed.
This is for a 94 Grand Cherokee A/T 4.0L with Federal emissions. The ECU part number was 56028310 and the date code is 10/07/93
Here is the file:
