MSII with fidle and ignition control

Post by hippled »

Hello
I am running MSII on a v2.2 board and running 2.36 code with MT 2.25. I am a little confused.
If you are not using a FIdle valve (using an IAC for example), you can remove Q5 from the V2.2 MegaSquirt PCB, and connect a jumper from JP1-5 to the hole for Q5 closest to R29 (i.e., towards the 'bottom' of the board, if you have the silk screen writing the correct way around). This will give you an ignition control signal on the DB37 pin #30.
if you do this do you need to tell MS that you did this so it turns off fast idle?

or
If you are using the ignition control, but not the IAC, you can connect the ignition control wire to any of the X11 to X14 holes, and retain your FIdle function.
if you do this, what pins on the db37 are X11 - X14. and is there relay board spots for these pins. Also do you need to tell Ms that you did it this way.
