Ok so I have EFI live and just bought an Edge Insight CTS to use as my DSP5 switch. I wrote the tune and made sure it is in serial not hardwired and I did a "full reflash" and everything went smooth truck starts and drives great but I can't change my tunes! I hit the up or down arrow on the CTS and nothing happens I am still in "power level 1" what did I do wrong? Is it possibly my switch voltage?
