im using the black cable with the usb/serial converter, i honestly gave up on getting the laptop to work for now (ill wait until i get the cable you're using)
you can actually tune very well with just the unit itself and my scanmaster 3 of course
if i didn't already own a laptop id be kind of upset to have bought one just to tune the maftpro...its totally unecessary IMO
I hooked up my AUX wire to the power wire of my water/meth pump and ive currently got a rough tune where I pull 5% fuel at 2800rpm and 10% fuel from 3400rpm to 7600rpm
i forgot how much fuel w/m injection really adds, the wideband a/f dives from 12.3:1 straight down to 10.1:1 when it activates
i have AFR tracking set to give me 12.5:1 across the board, how will the activation of the AUX wire affect this exactly?
