Hi all, I broke my aftermarket air intake temperature sensor and can't remember what one I used!!!!
It was one with known graph curve for entering into an adaptronic ecu.
it had a plastic/ceramic grid to protect the sensor the numbers and letters stamped on it are - ACR - 12V - 3
and also has 1801 stamped on it.
It also has a 2 pin plug

Probably General Motors/ GM AIT sensor.

Yep, Adaptronic gives the values for the GM open element sensors on the forum.

Thanks for that, Adaptronic also sell the sensors.
I remembered the company in the US i purchased the original from - DIY AUTOTUNE,
Same info as Adaptronic.
Thanks again, just bought the sensor from Adaptronic
