Where's your IAT? (CSL guys)

[marksae]

Okay, I want to move mine to the area below the snorkel too. Looks like I will get the E34 or E36 sensor and rescale the sensor calibration using ECUWorx.

I relocated mine to the air duct below the snorkel/intake, it was after the one on the Turner box was heat soaking so Hassan recommended I relocate to around here. Has been pretty solid since:

What is the point of this instead of using the CSL IAT? Why not just relocate the original?

The other sensor is threaded/with a nut so mounting is easier and the sensor portion itself is less prone to breakage due to the difference in design.

Sorry, I should have worded my question a little better. I am currently running a CSL tune with the stock CSL IAT in its original location. I want to relocate the sensor using an e34 or e36 sensor. Will I need to recalibrate my ECU?

Yea, you need to correct resistance calibration for your sensor. I think you can do it with MSS54 ecuworx software.

Did you ever find a 14mm cap to plug it? Where did you put your IAT?

I did, I found a rubber stopper (like wine bottle tapered cork, but in rubber) at local hardware store. I ended up cutting the stopper so it was only about 1/2" long, right in the middle of the size range that was right for the hole - something like 13.5mm to 14mm. Stuck in now, hasn't moved, and I've been driving the car a bit lately.

IAT is secured to bottom of headlight assembly right now, which is right infront of the air path from eventuri scoop to airbox "mouth."

If you ever need cap/plugs check out www.caplugs.com (free samples). I got the perfect cap for the lower inlet on the Karb box here (again, free samples)

I have a converted ECU that's running the CSL software and MAP sensor. I want to relocate my IAT. Which sensor do I use? Is the E36 IAT (p/n13621725323) the correct one to use?

That helps thanks! I can get a 14mm cap, and it should squeeze in.

Yes, that's the CSL sensor, not the gold-ish colored (maybe cad plating or is it brass?) E34 M5 iat.

Thanks very much.

Just moved mine tonight and switched to US Spec. Scaling to account for the different sensor.

Could anyone confirm which spec IAT this is? My cursory understanding is that there is a "E46 CSL" vs "US" spec? I believe the one I have pictured has CSL scaling? I am just trying to confirm for my tuner which scaling this one has. I think they have an idea but want us to confirm it.

Thanks
