Just uploaded and flashed DSP5 tunes last night. Went well, Went to install DSP5 switch, and have spent almost 8 hrs trying to diagnose the following problem.
Let me start with saying Nick at Duramaxtuner.com provided the entire package (hes been great!) I have checked and rechecked the pin position, and had two others verify...IT IS IN SLOT #46. Have done all the trouble shooting with Nick and we are at a loss!!
The switch is not changing to the different tunes. Have checked the Ohms through the switch and they match EFI's perfectly! Even checked to the opposite side if the harness, the part that actually connects to the ecm and all is great. Have abandoned the ground to the harness and attached to the hood ground... IT IS GROUNDED! Connect with efi scan tool software and do a real time logging and/or moniter of the E35 PID (DSP 5 switch voltage) and it stays constant at 4.68 volts... no movement when the switch position is moved. Even pulled the switch and checked the the thoothed washer and verified it is in position #5 when the switch is full counterclockwise.
At a loss and not sure what to do. Anyone with any ideas, please email me at dwilliams@gwstephens.com (easier to review) HELP:shock:
