Thread: Dirty Tach Signal From 6BTM

    Default Dirty Tach Signal From 6BTM

    I'm having an issue on my VW, with the ignition parts listed in my other post (LINK). I'm using a 6BTM box with a Terminator EFI system that's having issues breaking up over 4000 RPM. The tach signal is very erratic. I don't see any evidence of EMI noise. Is this an issue with the box?
