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.
