Hi all,

Doing some work to my r34 and at the same time trying to do a wire tuck and tidy the engine bay up abit,

Theres some wires that i cant account for, if somebody with a GTT (GTS is probably same?) could have a look it would help me massively..

The most confusing wire is located on the drivers side next to the fuse box, it may have gone through the plugs on the strut tower, Black wire splices off into 4 wires.. Possibly earth?

Starting with the red and black wire circled in green, i think i cut it awhile ago when i first put my manifold on but want to know what it was from, as seen the one wire splices into 2..

Can somebody also let me know what color wires go to the MAP sensor? I cut the plug off thinking i wouldnt need it since i am installing a haltec Platinum Pro, but now i think it may utilize the factory sensor wiring?

On the front of the engine circled in red where the top radiator hose goes in there is 4 earth wires that go into 2 lugs, Why do they do it like this instead of terminating the 4 wires at 1 point? I am now only left with 3 wires but i believe 1 was for something i no longer use, i am also going to earth it on the manifold further back so it is hidden,.

Thanks mate,

Do you know what the red and black wire is an earth from?

The earth's circled in red are 4 wires from 4 different sources,they still only have 1 earth point but 2 share 1 point and 2 share the other.. just curious why the 4 wires don't terminate at 1 point. ..

I have put the earth from multimeter on the same earth as a coolant earth before and had the coolant gauge behave erratically and thought this might be a similar scenario

    • Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.
    • Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler
