Its 2.13, I'm gonna reload it again this evening and see if I've over looked something. THANKS for the help

Where would i find the custom tune on my predator? All i see is 93/87 performance and factory tune

I bought the harness from DLH2006 on PT.net

yeah, when i turn ac on one fan comes on. The other never comes on even when up to the 180*.

Is there any way i can check my tune to make sure the fans are activated on pin 42 or what degree the kick on/off? I'm on my second tune and they still are not coming on. The ac trigger works but not through the pcm. I have ls1 fans and a 3 relay harness

I'd like to ...

alright sounds good to me. Thanks

I have the u7198 with ver1.03 for my 2000 chevy silverado 5.3, I'm sending it to you guys to update it to ver 2.13. What changes can I expect after it is updated?
