cth671 Posted August 31, 2023 Report Share Posted August 31, 2023 Hello, I’m trying to get my g4x xtreme to read speed from my t56 magnum with gm vss. It is wired in to DI 1 input. Vehicle is a 1998 Toyota Supra . Quote Link to comment Share on other sites More sharing options...
Adamw Posted August 31, 2023 Report Share Posted August 31, 2023 Ok, and what is the question? Have you assigned DI 1 to a speed input? Assuming it is a two-wire sensor and you have the other pin connected to sensor ground? Ensure the pull-up is off and your calibration is a non-zero value and you should have speed.

cth671 Posted September 1, 2023 Author Report Share Posted September 1, 2023 Yes I tried assigning to a digital input and put 235 in for the calibration and saw no speed. My speedometer reads though. I will try turning off the pull up resistor. I did have it turned on. Quote Link to comment Share on other sites More sharing options...
