I was just wondering if anyone has the pinout of this specific ecu?? My friend has an auto gsr, and we grabbed this ecu for it (37820-p72-902). When we slap it in it always throws codes 21 and 41 (which are vtec sol, and os2 heater). Soon as we swapped back in the 5spd Gsr ecu, everything is cool once again.

Also, I've read that this ecu has traction control... it's not effecting anything that I can see yet, so I just need the pinout to make the CELs go away for now so the vtec works again!

What ive noticed w/ auto gsr ecu hooked up: Soon as you start it, there is voltage going to vtec solenoid (do to the fact that we have a light hooked up to the vtec to see when it comes on), and soon as we get going into about 3rd gear the light shuts off (vtec turns off).

Just wondering if any1 can help with the pinout! Thank you guys!!

 

this is kinda an old post, i was just wondering if you had any further developements with this auto gsr? i need to convert my gsr to automatic cause i was disabled in an accident. not even sure how to do it exactly, having a problem finding someone to wire it up..

 

Might be easier to use an auto ECU and flash a GSR fuel map to it
