ok rite now i got a jdm gsr motor w/ bolt ons and im about to get it tuned on e85. i live in th emidwest so we have these all over lol.well heres my question..i was wonderin if i should jus buy the hondata s300 and run it on my p72 ecu or should i buy it with the p28 ecu. and sell my p72 on the streets.... i did some research and i read that i should buy the p28 and run that cuz if i would of run my p72 it would read the dual butterflys in the intake mani and would throw a check engine light and the stock p72 ecu is looking for the IABs (btw i switch the mani to edelbrock performer x so i would delelte the dual butterflys) i hope im sayin this rite lol but then i did more resaech and they said that its always better to run the stock ecu to make it run 100% or somethin lol... i dunno if anybody that has more knowledge then me help me out here.... thanks

 

The p72 ecu does not care if you have the dual butterfly system in place or not.
The only difference between the p72 and the p28 would be the native dual butterfly support & knock sensor support (useless).

 

so wat should i do

 

do whichever would come out cheaper to you as both ways are fine but if i'm not mistaken, wouldn't there be more outputs with the p72?

 

Run either ecu. They both will work for your application.

 

they both will work for you..

 

money aitn a problem.. i jus wanna kno wats better for it

 

....

 

ok waking this from the dead just to make sure on my own parts i can use a OBD2 p73 type r ecu with s300 and have no check engine lights or cel codes?

 

You can't use a s300 with an obd2 ecu.

Buy my chipped/converted p06 ecu. Same thing as a p28

 

If your car is obd2a or obd2b. You must use an obd2 to obd1 ecu jumper and run an obd1 ecu or use an ecu which has obd2 plugs adapted to it.
