My car is boosted, and my IAT sensor is not in my charge pipe, just hangs in my bay. Should i remove the corrections? It throws off my IDLE afr REALLY bad.

install your IAT where it belongs, period.

xenocron has a sweet little mounting aluminum plate that an obd1 IAT sensor screws to. i got it welded to my charge pipe..its great really.

The only right answer.... This is the 2nd important sensor there is underneath the hood. Its very important to measure the right temperature!

whats the most important sensor?

map...

why not tps?

because the tps does only tip-in enrichment and that sort of things. map does the amount of fuel and timing. IAT has the biggest correction on that.

What about heat-soak of the IAT in the mani?

Very informative thread Thanks! MantisX

Does the IAT sensor even react fast enough to warrant putting it in the charge pipe?

Heat soak is never a good thing and has to be avoid as much as possible. I see the best AF results with IAT sensors further away from the head. I run an IAT sensor like on the EK civic's and I never have problems like running lean when idling for a long time. When the IAT sensor is on the right place, the temperature does not change very fast so the IAT correction will be better then when the sensor measures heat soak. I had a B16A a while ago with a performer X manifold. The IAT sensor is at the back of that manifold and that gave perfect readings also.

when the IAT sensor gets heat soakes, idle will go lean correct? i get this problem car goes so lean it will not idle

Fix the iat correction for idle then

it is in the engine bay i even added '50' as the correction and still too lean
