I have some photos of the PCB (component + solder side) at: http://www.techedge.com.au/vehicle/gm277.htm Also, there's a list of the Delco part numbers. I'd be appreciative if anyone can shed some light on this ECU. Also, what is the US version (if it exists) of the GM "J-Car" and what ECU did it use? regards, -- Peter Gargano
