driftz240 Posted January 16, 2008 Share Posted January 16, 2008 i ordered a gm iat sensor and it came in one wire, should there be too? i dont think it will work if its not grounded via screwed in the engine or grounded in some way, witch it will not be if it is installed in my ic pipe. the other one they had at napa was plastic and looked like it went in a air cleaner box. what part number is everyone using to put the iat in intercooler tubing, or is a mat sensor better?

mobythevan Posted January 17, 2008 Share Posted January 17, 2008 The part number for the IAT is in the mega manual, it also has pictures of the open and closed element sensor so you know what you are looking for. Quote Link to comment Share on other sites More sharing options...
Matt Cramer Posted January 17, 2008 Share Posted January 17, 2008 GM sensors have two wires, one for the signal to the Megasquirt and one for ground. So they don't have to be installed in a grounded part. Quote Link to comment Share on other sites More sharing options...
badjuju Posted January 17, 2008 Share Posted January 17, 2008 ground your ic pipe, and shave off the paint right where it mounts in. or... go to http://www.diyautotune.com and buy Matt's: http://www.diyautotune.com/catalog/open-element-sensor-with-connector-p-116.html Done a lot of business with Matt for a project as low key as mine, great fella, and he's always been there for techie support if I needed him.

z-ya Posted January 17, 2008 Share Posted January 17, 2008 I run twisted pair for both the CLT and IAT sensors. Ground the sensor back at the MS, not on the engine. The engine ground can be very noisy. Quote Link to comment Share on other sites More sharing options...
