MSII v.3 unassembled kit...
OK, i'm building the thingamabobber and first option...
Tach Signal: Hall effect or VR? I chose Hall optical, is this correct?
I don't understand IAC stepper, our engine isn't stepper right, ...
erm, C-12 is empty (tach signal?)
Oh and i caught a mistake (step 54 or 55), with the whole thing about Ford and Mazda,
i put in a 2.49k Ford resistor instead of the 2.2k Mazda for the sensor table, go figure, but
my question is would i have to de-solder this and use the correct one
or can this be recalibrated in MegaTune?
