hey im wondering if anyone knows exactly where each of the ignition wires go and what they are exactly,

 

White/Black =

Red =

White/Red =

Black/Red =

Black/White =

 

these are the wire colors, i can test with multimeter if i undo everything and get to it or i can guess what should be what but i am wondering if someone actually knows what each one is without guessing and saying red is probably constant 12 and this is probably that etc etc...

RED: From 20A ACC fuse -->  ACC Relay 2  --> Junction Block --> Keyswitch

BLACK/RED: Front 10A IGN fuse/signal for IGN relay --> Keyswitch and tee's off to ECU also

WHITE/BLACK: 10A Fuse --> Tee's to signal both ACC Relays and goes to Keyswitch

WHITE/RED: ECU --> Keyswitch

BLACK/WHITE: Starter Motor, Inhibitor switch (Auto Only)

 

This is what my wiring diagram says anyway, looks fair enough

      If you take the top half of the intake off you can unbolt the flap off the shaft and leave the shaft in there blocking the hole. Then you can remove the little vacuum canister off from under the manifold and get a spare vacuum line to run to the ECU. I can take some photos of it later. Probably best to get the vacuum source to the ECU sorted first though. Mine all worked mint with the base map from the GTT an I've pretty much let the closed loop sort the fueling and took 1 degree out of the whole timing map.

      This IS something you also have to configure in Haltech (or at least I did in the past when going from onboard-to-ECU map sensor and an external MAP sensor in haltech land).

      I'm hoping it's something as simple as the ECU is looking for an external MAP sensor, but he is trying to use the onboard MAP sensor.

      You won't need to do that if your happy to learn to tune it yourself. You 100% do not need to do that. It is not part of the learning process. It's not like driving on track and 'finding the limit by stepping over the limit'. You should not ever accidently blow up an engine and you should have setup the ECU's engine protection to save you from yourself while you are learning anyway. Plenty of us have tuned their own cars, myself included. We still come here for advice/guidance/new ideas etc.  What have you been doing so far to learn how to tune?

      Put the ECU's MAP line in your mouth. Blow as hard as you can. You should be able to see about 10 kPa, maybe 15 kPa positive pressure. Suck on it. You should be able to generate a decent vacuum to about the same level also. Note that this is only ~2 psi either way. If the MAP is reading -5 psi all the time, ignition on, engine running or not, driving around or not, then it is severely f**ked. Also, you SHOULD NOT BE DRIVING IT WITHOUT A LOAD REFERENCE. You will break the engine. Badly.
