    Perfect warmup sensor for my aircooled MS3x bus

    Posted by Anton Iancu on Jul 25th 2020

    While this sensor initially fit an M6 screw I was able to easily modify it to install it in the m8x1 TS2 head temp location on the type 4 head. Works like a charm and helped me tune my cold idle easily with this in place.

    Install with sensor ground and signal to ECU and just pick thermistor calibration. Thank you Mario for the walkthrough and answering all my questions!

    Great product and Service

    Posted by Sam on Oct 2nd 2019

    I bought one of these to use on my KZ1000 that I'm converting to MicroSquirt. It's well a made product, and Mario went above and beyond in the customer service department patiently answering lots of questions from a guy who wasn't gonna spend much money. Already have and will continue to recommend The Dub Shop and these sensors.

    Easy to install and It does the job

    This works perfectly as a CTS on an ACVW. As a bonus, it also gives you an idea of what your CHT is. While certainty not as accurate as a proper CHT gauge, it’s comforting to see the indicated temperature go down as cooling fan speed goes up.
