also, if anyone knows what year range ecu will work, that would be helpful too!

sure, feel free to check the numbers!

ok, that helps a lot!! thank you. it seems almost impossible to find another ecu from a manual trans D21. i have located an auto trans ecu at a fair price and was hoping that the ecu from the auto trans D21 would work in my 5spd D21.

fair enough. i'll just have to pick up a copy for myself rather than be lazy and wait for someone to copy it, lol

the ecu will control the trans as well or wil it have its own ecu?

have you thought of scanning it and putting the manual in a pdf format so people may download it?

i'm interested in purchasing an ecu for my Hardbody pickup (i've been spending a lot of time here, as i have learned a TON from the Pathfinder guys here) and it is p/n MECS-G605 the heading on the sticker is 12. my ecu (currently fried by the previous owner) is an MECS-G625 with a heading of 02. my HB has the VG30I with a 5spd and 4wd. do you guys know if this ecu will cross reference and work or if the fuel maps will be completely off? i'm just rteally trying to get this truck up and going. thank you for the help. i can post pics if you guys want.
