I'm currently running a P30 ECU in my 95 EG w/B16. I'm wondering if running the P72 ECU I also have in my tool box will make any difference. Both are OBD I, so which is best? Thanks for any help

 

Its best to use the ecu that is made for your motor. Stick with the p30.

 

i'd love to know why you think running the wrong ecu for your motor would be beneficial.

 

sorry, I guess all of us can't be as smart as you.

 

It's common sense man. How would an ecu that is made for an 1.8 work well for an 1.6? DEDEDE.

 

this is a common question when getting into this sort of thing.
larger engine = more power. so use the ECU from that for more fuel and more power.

with our engines it doesn't work that way. Tuning is everything.
If you have a stock engine with basic bolt ons, stick with the stock ECU.

 

Thanks for helping me out. I've been in the game for a while just was a question I'd thought maybe someone could help me with. I've got a turbo B16 that has a great tune by jeff Evans, but for my beater I've just got bolt ons and didn't know if maybe the p72 could make a difference. So now I've learned that it isn't the correct ECU and to stick with the P30. Thanks to everyone for all their help
