Originally posted by SilvrEclips Can someone just post a nice big pic of what the v2.2 board is suppose to look like so I can change mine around to match it. Instead of figuring out whats going on I planned on just removing all of the alterations and starting from there. Also I started building my wiring harness and noticed that they gave me a lot of IAC wires but not a crank position sensor wire. The pic of the 2.2 board wiring doesn't show a CPS but the 3.0 wiring does. Do I just hook the wire to the same pin?
I dont know whats going on there with LED 18. In Megatune, LED 18 can be configured for output 4, which can be fan control or any temperature/hysteresis controlled switched output. So the connection to the negative side of the LED 18 hole is ok, but why they took that wire to pin 6 of JP1 or Processor pin 16, is beyond me. That is an output pin, although I cant find anything in Megatune that uses that pin for any special features..I dont know, i havent messed around with MS1 in quite a while, mostly MS2 stuff now. It's hard to tell about the other jummpers, but it seems the input and output mods for spark and the crank sensor are there, although its hard to see if they are correct.
Anyway to find out who built the board? It may help to ask them whats up with it if you can. As for the crank sensor wire input to the MS, you just use the normal "tach or coil" input wire. Look over the 2.2 schematics very closely and try to follow the circuit mods from the diagram to your board. It's not that hard to follow if you really try.
Also, have you opened up Megatune and seen what LED18 is configured for? That may help..assuming the MS1 chip has been pre-programmed by the seller/builder.
