Does anyone have experience with this system? The car starts and idles but when RPM's come up it starts backfiring and missing. Mice got into the engine harness. I've inspected the harness engine to computer and repaired chewed sensor wires. The throttle body has 2 electrical connections to it and the wires are unaffected, as far as I can tell.

I need to connect diagnostics to the system, which I've never done. What software and hardware is needed?

Does anyone have an online training reference?
