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.
