I have a P72 on my GSR and I want to dyno tune my car with a hondata. I dont want any downtime on my car because its my daily driver and I dont want to send it off my ecu to get socketed. Anyways my question is does it matter if the P28 ECU came from an automatic car? I dont think it will make a difference but I want to make sure before I buy it. Let me know if I can use the P28 OBD-1 that came off of an automatic ex on my OBD-1 Gsr motor. Thanks

 

Yes, it does matter. It will not work.

 

correct me if I'm wrong but can't you remove a jumper wire from the ecu? I could have swore I read that you can convert the ecu to manual....fuck now I gotta look that up.

 

Yes, that P28 can be converted. I can also socket that P72 for you.
Actually I might have a P72 I can swap you if you need something to use while it gets chipped.

 

Wrong. A auto ECU will work in a manual car but a manual ECU will not work in a auto car.

You can convert it to auto man

 

you contradicted yourself.....
He has an auto ecu and manual car.
You can convert it to manual.



Oh my god the allmighty 0psi was wrong!!!!the world is coming to an end.....

 

Actually an auto ECU in a manual car will work like ass unless it's converted to manual. It will work, but it will be running off of the auto parameters, which are tuned a bit different than the manual parameters. So yes, you could, but you don't want to.

 

Sorry, i was on the way out the door typed to fast and didn't think at all

i meant to say it will work but be best if it is converted.

 

is it OBD1? wanna sell that P72 to me for a good price?

 

Actually I'm holding it for until the owner pays me for chipping it, so I can use it as a loaner but not for sale, sorry..
