Thread: MAT needed or not?

  1. #1

    Default MAT needed or not?

    I have a Stealth low rise intake. There’s no place on the intake for a MAT sensor There’s a place for the MAP on the bottom, but not for a MAT. If it's needed anyone have a part number for the right one. Then the next part would be placing it. I'd have to drill and tap a hole for it.

    I have a place on the bottom of the intake I can install a sensor. I found this GM 25036751. Will this work? For some reason the guy that wired the ECU cut and removed this plug all together. I was looking at what was on my Chevy ll and saw it on it. Found the wires, got a plug, now the sensor. If I can use the GM one, I should be able to get it at a dealer today.

    @3DTim: You can also put the MAT sensor in the intake pipe ahead of the throttle body. I prefer the quick response Rife sensors. V6 EFI has the calibrations in the drop down.

    If you prefer a push-in style GM sensor that can go into a 1/2" grommet, look at ACDelco PN 213-4663. Use the Holley MAT calibration for it.

    And...it's definitely not optional. Fuel compensation for intake temperature is a critical part of the fueling strategy. I also always pull spark timing if temps go above 140°F, although this rarely happens with naturally aspirated engines. Andrew
