P72 or P73 ecu for GSR B18c motor?????

[B18cbubble]

i have a B18c motor and i have both the P72 and P73 ecu's. which should i install?? the P72 because that's the stock ECU for a GSR motor?? OR the P73 which is for the type R motor??

will the P73 give more power??

The P73 is 9000 redline and my motor is 8200. also the P73 is a little different with ignition timing.

which should i install??

p72. install the ecu that was meant for your car. are you doing future mods?

you i have a P73 also but i just chipped a p28 with ITR specs works great!

Would i see any gains from a P73 ??/

if i use the 73 i'll have to have all the sensor hookd up

what motor do you have? if its a GSR motor you will loose power running the p73 ITR ecu
