anyone now where I can find out about the harness on the P11 ECU???? I just bought an Apex-i Multichecker and just want to make sure I don't screw up...anyone now where I can get it??
or if anyone knows anything or have installed one...Thanks

Tony

You need a factory service manual. It has all the ecu wires explained. What do you need I can look it up for you. I installed my Apex'i rev/speed meter. No problems.

Whats all this about can you explain a little about this application.

What does it involve, what add ons, what gains????

Thanks for the hel G-forces:bloated:

The multicheck that Tony want's to install can be used for tuning purposes. It will read out injector duty cycle, MAF voltage, rpm among other things.

The rev/speed meter I have it purely a toy that looks cool. :) Meter's revs speed some timing functions, 0-100/200/400m, 0-100/200/300km, peak hold functions and a trip odometer. Speed and rev trigger outputs. There may be others but I forgot them.

Is there an apexi gizmo that will let u set your rev limiter a little higher or even change your fuel/air mix with out having to open thing's up!:bloated:

That would be the apex'i AFC (Air Fuel Controler)

:sun: Than-x budy!

G-Force do you have a service manual for a P11? or maybe even P10??? If you do help me out please...

i want to know the exact wires that the multichecker taps into on the ECU...The picture I included is from the Apex manual and it says the P11 is N2 harness but I need to make sure it is before I start splicing wires....thanks for your help guys...

DONT use the S13/14 ecu settings to use it on your P10/P11...it's different. As jason mentioned, check with the service manual for that, it's fairly ez to obtain, just go to the dealer and ask for a copy, that's what i did to hook up my turbo timer, EGT, boost, oil temp, oil pressure and my AFC...now i just need to put the turbo in :)

:o Hey Luke you think you can give us a good pic of your engine, I would liketo see how some of your stuff is done under the hood, I know you said you like a classy clean ride, so I was wondering what your engine bay looks like.:licker:

G-Force can you help me out??? I need to know the pin numbers of the Injector #1 and #1 Ignition signal and crank 1 degree and crank 120/180 degree and MAF and speed signal if you can help thanks...I am getting super frustrated with this...thanks if you can help me out...

Ok this is for the 99 ECU only. I can't be 100% if this will work for any other year. The pic is a scan from the 99 FSM. Anyway.

Injector #1: Pin 102; color R/B (red/black)
Ingnition #1 (try): Pin 3 (tach); Color L/OR (blue/orange)
MAF: 47; color OR (orange)
Speed: 26; color Y/G (yellow/green)

The crank position sensors are a little trickier. I'll give you the pin outs but it looks like they all key off the same 0-1 degree area.

Cam Position (reference) 40 and 44; color both L (blue) (2000rpm is a 5v signal every 10ms (spike signal))
Cam Position (position sig) 41; color B/W (black/white) (2000rpm is ~5v signal at 0.2ms the signal looks like a square wave that goes to ~0v at 0.1ms)
Cam Position (ODB); color W (white)(wave signal around 0v +/-5v it's a little hard to tell the frequency. Looks like 0.7ms frequency at idle. 2000rpm is to hard to tell.)

That's about the best I can do bro.

G-Force you are the man!!!! thank you for your help...I didn't expect anyone to help me this far...damn!!! thank god I have friends like you...anyways all the pins you told me are the same I have spliced already....but I'm not getting speed and ignition...thanks for your help again...thanks

right now it's nothing much to look at...only a JWT POP, Stillen strut bar, Greddy oil-catch can (for my coolant reservoir)...pretty much looks like everyone's motor...BUT after a couple of weeks, when the motor goes in...hehehe, there will be lots of goodies there...SARD fuel regulator, another Greddy catch-can, bronze (color of the TE37s) valve cover, possibily an aluminum ARC radiator, Blitz intake, Blitaz Dual Drive BOV, HKS intercooler..as you can see, i got lots of stuff piled up in my garage wiating to put in hehe...but the engine will for sure look clean...cant wait!!!
