Bowler All-In-One Wrong Speed

[AU Doc]

My ECM can be adjusted to handle either input, but this is showing up on the All-In-One app. So the crazy speed fluctuations are what the All-In-One is seeing directly from the transmission and that’s being sent to the ECM.



I’m using the 40ppr output, and have my Holley ECM set to the same. In troubleshooting the erratic speedo readings I went back to the Bowler unit to see where the problem is.
