HP tuners cable issues??
the cable, and everything to do with the power inverter I
was running the laptop off of and the unvervoltage situation
on the truck. Underdrive pulley made it run about 10.5V at
idle, which is the cutout voltage for the inverter, and when
the IGN bounced the inverter kicked in & out and after several
of these, serial no worky.
Ground loop bad.
