First time I've ever heard of this, and I have this in a number of locomotives that have sat for over a year and work fine when I fire them up again. This has also never been reported by the hundreds of users that have installed the Chuff-Generator. There's no reason it should ever forget the calibration, it's stored in FLASH when you do the calibration.
I suspect you're seeing an issue with the tach strip or sensor spacing that is resulting in not reading every stripe on the tach tape. That's a lot more likely than the FLASH forgetting the calibration.
Chris,
I agree with GRJ’s response in regards to your situation. The Chuff boards are non-volatile memory and flashed during programming/calibration therefore they should never reset. Possible wiring issue or like GRJ said, misalignment of the sensor? Please let me know if you figure it out.
