my p12 ecu

[$KAT3R_rc]

hello everybody i justed switched out my stock ecu out of my 93 honda accord lx auto. i pluged the p12 ecu in but i have no tack and i can't get out of park. the ecu i bought was out of a prelude manual but everyone has been saying that the ecu controls engine TCU controls tranny.

EDIT: if i put my key in the thing where i switch gears. i can go but its like staying in limp mode or something. 1st gear doesn't work it just stays in overdrive. it has no power what so ever.

ok what the hell. i don't have the plug in the very small one of the three that plug into the ECU. i think it is a 16 pin connector. i didnt know i had to plug that one in. i only pluged the ones that are on either side of that 16 pin connector.

ok the ecu would control the tach or so i would think being a engine function.....also the fact that you have a extra 16 pin or so connector unplugged that could be where the tach pins out and it's simply unconnected....but the not shifting when the tranny has a tcu leaves only one thing that the fact it is a manual ecu and leaving out something between the ecu and tcu causing it to run in your limp-mode possibly being the same 16 pin connector not hooked up .......i would try automatic ecu or check out some pinouts of the ecu and on your car maybe you can do some jerry riggin if you gotta have the extra 6 or 7 hp.....PEACE

No, don't bother with a auto ECU. I had a manual P12 in my auto and it worked fine.

And did you even read his post?

He left one of the connections disconnected. I'd venture to say that is 99% of his problem.

You are a re tard

Thanks for the helpful comment! I hope you get banned for it.
Never mind, looks like a mod took care of that unwanted post.

he pluged it in backwards and the tcu instead of the ecu have fun with all that torque

[lowandslow_88]

congrats....your ECU is fried.......many failed attempts with a ECU not completely plugged can cause hell of electrical problems...

oh about the Fried ECU part i was just messing around...lol..but the rest is true..

[deevergote]

If your CEL is on, fix the problem.

[$KAT3R_rc]

but deevergote the f22a1 out of the prelude the MAP sensor isnt on the TB? do i just need to get a TB out of the prelude?

[deevergote]

Why does it matter where the MAP sensor is... hook it up properly, or replace it if it's faulty.
