Ok here is the deal i bought a v2.2 from a kid that put one on his 2nd gen. He loaded the base map and said it worked, he gave me a sorta bad wiring diagram, i spliced it into my harness ran a few wires and whala it started up. I am stumped on were to hook my oxygen sensor, cant reach the kid and want to use it. I believe its pin 23 on the connector can anyone verify this. Also what program do i use to update/modify megasquirt, is it called megatune ?, any tips suggestions, also car idles at around 1500 ?, and causes in the settings to check for Please Help me someone with this

 

pin 23 is o2 input.
You can use easytherm to change your therm files and flash firmware. The firmware package also comes with .bat files to flash, and .bat files to setup .ini's.. check the readme with your code version ...
Megatune is your settings and tuning interface.
I would suggest reading the tuning section in the megamanual ... a few times ... tons of good info there. The FAQ by muythai here should cover the rotary specific settings, and you could always post your msq if you are really stuck! hth...
