I have an MS Labs MS3 Basic + MSLabs CANBUS Module on a 97 with ODB1 Rewire
, and a home made grounding kit w/ 4guage copper wire at
Battery Negative to Chassis (stock location)
Alternator to Chassis (engine bay)
Cylinder Head to Chassis (engine bay)
I think there may be a ground loop cause there's a lot of noise when I use the aux input on my radio with anything charging in the car. i.e. aux connected to phone, phone charging thru car 12v accessory it'll produce a lot of noise and whine when I'm driving.
WB Input through the CAN module is set up properly. It reads correctly 40% of the time in TunerStudio. Sometimes it reads the error amount (set to 14.8) or it'll get stuck on a number. Other times it works flawlessly and updates really fast.
Grounds seem to be the obvious answer. What if I ran the ecu ground directly to the battery would that help? I'm going to remove my grounding kit and see if there's any difference.
Appreciate any input on this Thanks!
