I just changed over to a 2 bar map and eliminated the maf. How ever when I read my scan it's telling me my intake air Temps are -31c. What sensor tells the computer this so I can try to figure out how to fix.

01 LQ4 lower end, with LS3 heads and L92 intake.

Did you have a 3 or 5 wire MAF? If you had a 5 wire the IAT sensor was in your MAF and your going to have to get a IAT sensor and wire it in.

It was a 5 wire MAF.


So My guess is I have to Wire in a IAT sensor but would want that after the IC right?

Any suggestions on where to put it or what one to get?

Is the MAF still in the car or did you remove it entirely? If it is still in the car, couldn't you just keep the temp sensor/MAF plugged in? Then just disable the MAF.

If not, I installed mine in the front bumper.

I like to run the IAT right before the TB to see what the actual air temp going in. You can either get one for a 98-02 camaro that uses a rubber grommet to install or there is another one (cant remeber the vehicle) but its all metal and threads in.

What is your opinion on installing in the front bumper or inline before the TB? I know I was seeing heat soaking with mine inline , that's why I put it in the bumper, now I get the actual outside temperature.

You dont have a part number do you? Or even better a sponsor on the site I could call to get sensor and pig tail?

Will this work? http://www.ebay.com/itm/GM-Delphi-Pa...-/331515217715

I sure dont, that looks like what I used to use though.

I've always wondered just which air position was proper
for a boosted vehicle. All along the tract you are trading
pressure, volume, temp yet the SD air mass calculation
would need manifold pressure and manifold temp to be
proper. I'm guessing that the PCM has a scheme to figure
manifold temp from IAT temp by BARO-MAP pressure drop,
in the NA stock form. But what this -should- be, for a
setup far from stock, I have no good idea and so far have
found noone who convinces me they know.

And when you have boost, and air temps, swinging wide
and fairly fast, the IAT's slowness could make for some
interesting transitional fueling issues I expect, if you are
looking for it to follow reality and quick in some after-
impeller position.
