If you have any questions, please email us directly, phone or just post here. I'll try monitor things as best I can between writing template data and testing vehicles. There's a 10000 character limit in the post, so I had to split it up.

You'll note I didn't post the trouble code listings. You'll have the option to enable or disable the trouble code test in the software, also.

Note the pricing options on our website in the software section of the price list.

Thanks, Lyndon - I appreciate the effort and time taken to assemble these lists

[AndyL]

Major Thanks Lyndon,

Do any of your reflashes come bundled?

[ECMProgrammer]

When you order a personal version, we also send the calibration that was for your truck based on your VIN.

so with all the parameters you can edit, is it possible to drop in a 12v cummins in place of the 6.5 and still have the computer control the 4l80e and the gauges? I want to drop a cummins into a 98 ext cab 4x4 body and have the gm ride with all the benefits of the cummins. Can you do something custom for this application?

I'm guessing using a 12v say 94 to 98 all that would be needed would be a tps & speed signal to run a 4L80e while leaving the IP harness disconnected (its would throw codes relating to IP).

I've spent lots of time trying to get a standalone tranny controller for my burb but the autotrac t-case becomes an issue because it's intergrated into the ABS too.

You'd just disable the codes relating to IP.
