Programmers seem to be puzzled by not seeing everything a typical truck should have when it establishes communications with the ECM... When using an aftermarket programmer, it'll "look" at all of the electronics the truck should have. It'll interrogate each system and look for a response. The IP panel gauge cluster is one system that a programmer spends some time with, checking the fuel gauge, checking the oil pressure gauge, tach and so on... I'm not sure how yours might respond if you decide to use a programmer.

I can use a programmer on Lil Red, but it ponders things a bit longer than normal cuz it's looking for the airbags, ABS and the factory HVAC controller. My truck doesn't have these three things. I need to cycle the ignition a couple more times than normal to get it through the upload process, but it works fine otherwise. Again, I'm not sure how yours might respond when using a programmer and without an IP gauge cluster.

Otherwise, the Edge Attitude and VanAaken modules work great, without any issues. I'll be trying a Kennedy ECM here shortly.... one that's been tweaked for perhaps 600 on nitrous....
