|You are shooting in the Dark.. If you get ECU Talk or Consult Software. you can see some of the Inputs the ECU is Looking at, then things will become more obvious..
1) Lap Top.. I run an Old XP Machine.. $150 E-Bay
2) Consult Software.. Licensed..
3) Consult Cable Compatible wit Ports and Drivers of the Lap Top.
I also Chipped my ECU and am Running a Moates E-Rom Emulator and TunerPro Software.. I can change my ROM on the Fly through the USB Cable..
