Am getting a Haltech MAP sensor based ECU installed & tuned on my RB25 R32 & need an air temp sensor.

Have been told I can use an RB26 item.

I thought these were incorporated in the AFM but am hoping now that I was wrong.

Was also told I could use a Delco item which is something I assume could be bought from automotive parts stores but surely they sell more then one type...

Has anyone used a MAP sensor based ECU & had to source an air temp sensor & if so what did you get & where from?

Cheers,

Brett

the GTR air temp sensor is the same part # as the water temp sensor that the ECU uses

so find the part # for that and away you go

be sure to note there are two water temp sensors

one will be the for the ECU (this is the one you want)

and the other is the dash gauge

drop past meridian, they usually have a good assortment of Delco and bosh AIT's.

If not osaka or type m should have a few about the place. I just checked and dont have any laying around.

There probably are, but i havent investigated. If you have a look at an aftermarket sensor, it is a small diode or a piece of nicronium wire, which is sensitive and reacts quickly. The nissan one reacts very slowly, which is fine for what it does with the stock ecu, but its role is far more important with a map sensored ecu.

Ok, I am about to put in an EMS Stinger 4424 into my RB20 R32 and was not aware that I'd need an air temp sensor... can someone point me in the right direction to sus out what I need to do please?

Thanks in advance

    • Old Son, did you re-use the Holden ABS in the new shell or try a different module?
    • Yeah, nah. I had the actuator rod off it today. The arm will not move at all. Neither out, nor in. Yeah, you'd think so, but I've been thinking about that. Even when the actuator rod fell all the way off at the beginning of this saga, it would build more boost and faster in lower gears than it would in higher gears, and you'd think that that was the opposite of what should happen. But I strongly suspect that there is a thing with the gearing getting the revs to rise faster, that there must be some transient effect with the gas flow rate rising quickly, that you don't get with the more steady state case of the higher gears. Keep in mind - the gate is not shut in either of my weirdnesses. So things are not "normal". We normally think about a turbo spooling up (below the wastegate target) with the gate shut. I have all sorts of mental models running now where the gate is a little bit open, and having it stuck open allowing gas out while it should be going through the turbine has all sorts of weird effects (in these mental models). I'm thinking in the higher gears, the ex mani pressure builds to the point where enough gases spill out the wastegate to just prevent the pressure rising much more at all, or just creeping up, all the whole the revs are increasing and getting closer to the point where a gear shift becomes necessary.
    • Is it possibly wastegate actuator itself is sticking, or even the rod to flapper? Otherwise I reckon things are getting a bit rusty/worn   Also odd it won't boost in 3rd to 5th, but will in 1st, I'd expect the other way around with it slightly open as there's more time on your way to redline for it to spin up
    • Does anyone know ow what these two plugs are for and if they should be unplugged? Just put the dash back together and can't remember if these were plugged in before or unplugged! (Blue and white plugs) 🤦🏽‍♂️
    • Did some FASTing ...got the impression that the actual part# was a moot point ; seems all of these hardlines for coolant are discontinued/NLA... like, I take it you're after the hardline that bolts onto to the manifold...that's NLA according to amayama & nengun .... ...just to clear up some confusion, they typically mounted the AAC valve to the intake manifold somewhere near a coolant passage, so the body of the valve heats up & holds it open when engine's up to temp - no coolant flows through the valve, it's a mechanical, thermal connection.
