Watsup guys, I have a 94 gs-r that i'm rebuilding, a friend a mine has a chpped p28 ecu that he's willing to sell me, whould that be better to use instead of the stock p72 gs-r ecu.

O yea, if anyone has a OBD1 gs-r wiring harness for sale i got your money right here. (theives cut mine, bitches )

 

Only a P72 ECU will operate the IAB (Intake Air Bypass butterflies in the intake manifold). You can wire an RPM switch to do this as well. Is your engine stock?

 

If its stock leave the stock ECU. If you get a chipped ECU chances are if its not tuned for your particular car, it will run like ****.

 

yea i have a stock motor. my original ecu was stolen dats why i was wonder whether to get a chipped p28 because i was having some trouble finding a obd1 p72.
The friend who's selling the p28 ecu says the vtec kicks in earlier and the fuel settings where changed to give a higher flow.

 

OBD1 P72's are hard to come by............. id stay away from the chipped ECU though.

 

ha ha that sucks man... i am also rebuilding a 94 gsr and they cut my main harness and my dash harness. i am running a pr3 for now i think

 

oh but i am also going b20vtec cause they stole the motor and trans too.

 

Koo p72 it is. I just found one for a $100. All i need now is a harness..the work continues.. thanks for your input guys

As the others have stated, stick to the stock obd1 p72 (94-95). Once you start modding your motor and getting cams, pistons, etc...then a chipped p28 might be something to look into.

Keep checking the classifieds on here...I know earlier today, I saw someone selling a GSR harness..let me see if that topic is in my recent topics.

 

I am running a chipped P72. There is really no reason to downgrade to a P28. You will lose control of your knock sensor...and for a daily driver, that might be a good thing to have.

 

thanks for all your help guys i now have two p72s and i'm rewiring my ecu harness, what funn!!!!! (was cut)

 

P72 just keep it stock.. Rewiring sucks! Theres alot of double wires that can be put on backward

I have a 95 gsr dash harness.. I'll sell for 100
