I guess the Stock ECU also should be running the tach, but I could work that out as well.
I'll have to see what I have left in the way of pins on the MS2 unit.
For AC control, does the condenser fan come on any time the button is pushed? (assuming I ground the AC relay).
I was just planning to leave the stock ECU since it should in theory do a fine job of running those 4 things. This is a budget car for me, not my daily driver nor a show car.
