Ms2e 99-00 ac control
 

I got my car to run and drive fine buy the only problem is the ac doesn't work, if I go in the ac control and select idel up pin, I'm not sure what input to chose. When I press the ac button it lights up but nothing happens. Any help would be nice as I daily drive this car in florida .

Anyone?

Exactly what MS2 variant is this?

this

It's a rev built ms2 e

email rev for support.

I have pm him and emailed and no response yet I'm just seeing if anyone knew

not entirely sure the a/c control in that unit are even tied into the ECU, but his enhancement board.

These are the setting that show up when I enable it
I dont know what pins for the input and output.

youre assuming the ms labs ms2-e uses the standard firmware and a/c controls...

No, I put the pic to see if anyone can see what I have wrong.

This is one of the oldest units out there.

The A/C control does not go through the ECU, so the firmware is irrelevant.

The control board looks at the RPM and TPS signal to actually activate the A/C once your press the A/C button.

The first question though is, does it see the A/C button? Is there enough refrigerant in the system?

The ac worked fine before so there is enough refrigerant when I hit the ac button the clutch isn't engaging. The rpm guage on my car also is not working as well once I put the megasquirt in could that be am the reason the ac isn't kicking in

Probably so. If you updated the firmware on the unit (looks like so), make sure that tach output is enabled and set to TACHOUT.

Thanks I'll try that when I get home.

These are the setting and the tach still doesn't work.

so set it to TACHOUT from JS10 like Reverant said...

I don't have TACHOUT as a selection

oh, i see, you flashed your firmware incorrectly...


exactly why did you flash your firmware in the first place, let alone for the wrong baseset?
