link g4 air temp sensor

[tez n u]

Hey guys just wondering how this gets wired in, can we use the factory intake temp sensor plug in the v6 sti to wire in the aftermarket air temp sensor for the link g4? Do we need to do something else wiring wise to make it work? Also what color plug is for the intake temp sensor as on my car the sensor and afm was removed when i bought it as it was running a possum link ecu I can see the afm plug but dunno which plug is used for the temp sensor ???

you need an expansion loom, its only about $50, it plug onto your main board and gives you extra inputs, you can't wire it to where your old air temp sensor was

really? crazy thats one step backwards compared to the g3.

i guess they wanted the extra $$ for expansion loom

[Stoffa]

Theres only 1 analog temp on the main board and thats used for engine coolant temp, the other 2 analog temps are both on the expansion loom

I wen to torque performance today and was told i can wire it in using the factory wiring and just have to swap a wire down at the ecu ???

Are we talking an accessory sensor here or is this a sensor you need to run the G4?

Its not needed to run the g4 as im currently driving my car around with no air temp sensor but its more of a safety feature , i have already bought a air temp sensor from torque and having it fitted to my intercooler pipe tomorow, hopefully we get it sorted by wednesday :-[

Is it so you can set a fail safe or something to turn the boost down if things get a bit hot?

Is it needed to remove AFM?

I run a blitz boost controller so it cannot turn boost down unless you run a link boost control system which is controlled by the ecu, it will pretty much retard timing if intake temps get a bit hot

It sort of fine tunes your tune depending on the intake temp, keeps it running smoothly with big temp changes. temp sensor goes after the intercooler just before the throttle body, one of big differences over the possum link

Ah yep, makes sense. Definetly a pretty important bit of kit if you have spent the coin to get G4 then.

Sweet connected the sensor using an expansion loom ;D

U can do it without the expansion loom. I did it that way but yeah easier just to spend 50 and do it the easy way lol. I soldered a jumper on the underside of the board to the purge solinoid trigger pin on the header then used the factory wiring in the engine bay. (custom fuel setup so no charcole canister) Saved me running extra wires thru the fire wall and buying a loom but wouldnt reccomend it to a random person lol.
