new setup, quick question - SRT Forums

HTG · 01-25-2013, 09:32 PM

finishing up my turbo build, car is off at my tuners place waiting for weather to clear.

tuning with dsp and using a n2mb boost box to control boost. i converted my aem cai into a sri by removing the bottom half. now i dont have a hole for the AAT sensor.

will leaving this sensor out of the intake make ANY difference in performance with the setup i am using? would it be better for the sake of the tune to have it plugged in?

if so, ill see if he can drill a hole and have it inserted.

thanks!

No the Amb temp don't do anything. For performance.

Just let it hang.

I ran mine just hanging when I was stock on pcm controlled with no issues what so ever

Did mine the same as ^^^^ when I was stock turbo on pcm controlled. Then, switching to e85 and mbc, let it hang and also being bigger turbo and running open turbo and 33-35psi, sensor being disconnected didn't hinder or rob any power.

Just let it hang out in the engine bay.

That temp sensor isnt as important for performance as say the charge air temp sensor.

Why would they put an ambient temp sensor IN the intake? Usually D/C puts them in the fender or behind the bumper and they are used for HVAC.

NorthNJSRT4 · 01-26-2013, 10:24 AM

The ambient air temp sensor is mostly used for emissions control calculations and in '05 cars it doubles as the battery temp sensor to, in part, control alternator output. If you datalog, you can use it to calculate intercooler temperature efficiency. Beyond that, like Tunerlover said, it's not as critical as the inlet temp sensor so hanging it in the fender won't hurt anything.
