p12.ecu with f22a1 mpg ?

[Teddy]

hi do you think my mpg will go down when i put in a p12 ecu ?

[Oja]

I doubt it, probably not nitcable if soo

[Gman86]

just installed mine today, ive seen no difference in 87miles of driving.



But on a sidenote, my alternator crapped out, and my heater hose burst!!!!

Of course the ECU being installed the same day has nothing to do with those events, but man everytime i make an addition/modification/maintainence to my car a different problem surfaces. lol

[Teddy]

cool great to hear about no loss of mpg

[deevergote]

Probably about the same MPG as a 1992 Prelude S.

[OldMan'92Accord]

when i had my p12 on i got around 25-26 mpg freeway driving.

[kouzie]

For as long as I remember, I haven't notice any difference at all.

You can't tune a p12.

thank you all for helping me ..when i get the ex headers on i might use the
p12 ecu or the ex ecu dependes on how much $$ i got ..

You cannot tune any Accord or Prelude ECUs.

People REALLY need to stop thinking of the P12 as some miracle mod. It's a stock F22A1 ECU, made for a stock F22A1. That's it. That's all it does. It does not add 10hp to an H23, or F22B DOHC. It does not add 10hp to an F22A6. It cannot be tuned... and if it could, it would defeat the purpose of "being a P12" anyway.

According to the dyno around here, it only adds about 3WHP to an F22A1.

Not only would doing the A6 parts on an F22A1 result in more power, it would probably give better MPG as well, at least based on my experience.

I had my P13 tuned. Well he removed the speed limiter and changed the VTEC engagement and Rev limiter. Also said he changed the fuel maps for partial throttle cruising so I'd get better highway mpg.
