I just purchased the Vems bluetooth to serial adapter and I am getting interference with my TPS and Map sensors. I have the plug powered using pin 28 5v power supply. I do not get interference until I am connected to my pc via the bluetooth signal. I haven't had the time to test if other bluetooth products cause this same interference.
Interference was verified using an oscilloscope.
Did I install this wrong? Is this normal and I need shielding? Any other ideas?
Thanks.
