or if anyone knows anything or have installed one...Thanks

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

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!

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

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...

[G-Forces]

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!!!
