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?

I'm sorry if this was a stupid post, i just found my answers... i still don't know whats the deal with the IAC stepper...

Aussie Driver

The big deal with the IAC stepper is that MSnSE won't control one. But as you said, we don't have an IAC stepper so it's not important.

Mouglie

so what do we have?

Aussie Driver

We have a 3-wire Bosche IAC/ISC valve. If you do the PWM idle board mods then MSnSE will happily control the idle.

Mouglie

kool... i'll do the PWM mod...

but i just went back through the steps and
i skipped step 22... to make this quick, should i use
a gm sensor or what should i do in this step?

arhhh i see red letters, i don't wanna burn anything,
ok i got a MSII so that means i'm not burning anything right?
(i'll take a brake now)



thanks in advance...

Go with your first instincts on this one. Leave it skipped.
