Just curious because I was going to sell a '94 ECU on ebay that I don't need anymore. BUT, my friend gave me the wrong one ('90 ECU - 37820-PT3-A01)

It doesn't really matter which I sell to me because I just wanted some spare change. But I was curious if one is better (more valuable) than the other.

Any info here will help me. (I thought I heard that some year accord ECU's could be chipped and some couldn't).

 

thats the controller for the trannie most likely. i got one im trying to figure more about it right now. do manual transmissions require these i know they do on the ones bolted in by the steering column under the dash. there are 2 controllers from what i have seen on an automatic one beside the ecu and the one i was just talking about.

 

on pre 96 ECUs they required a separate ecu for the tranny, now they are built in. a manual tranny doesn't require an ecu, hence the reason it's called a "manual" tranny.

 

accord ecu's areall pretty much low value items.
the pt3 is a dime a dozen in junkyards.

 

well maybe you can answer a question for me now since i have been searching for this answer for weeks i ripped a '92 prelude trannie and all the control modules i have one thats for the srs another that is the actual ECU P13 Which is now Useless for the motor i have. its up for sale if anybody needs one $80. but i have a little black box with an 8 pin plug on it made by shindengen part # 37740-p12-a01 any help would be useful.

p.s. thanx for the clarification on '96 +

 

i have one too but im still figuring out is it useful or not...

 

lol.....This thread is almost 6 years old.....

What one do you have? The 8 pin black box or the P13 ECU. The P13 ECU could be usefull if you have an H22. The 8 pin box (37740-p12-a01) akkordh23 was talking about is the rad fan timer. You might be able to get $80 for a used one. They are $120 brand new.
