More help with idle + megasquirt.

Post by Scottinva »

I still don't have idle, I have glen's garage board properly installed in. I double checked my idle valve on another m30 its working perfect. Something shorted out with the other board made by the previous owner, I put in the glen's garage and still no idea. Is there a way to check the F-IDLE output. I have an oscilliscope and was wondering if I can check it for htat, and if so any idea what the wavelengths should look like. I have looked over the basic megasquirt wiring diagram, and can't really see what would toast if the f-idle shorted or something. My quess is a mosfet on the megasquirt board. Any ideas?

Have you accessed the Idle PWM table and the Idle Wizard?

Yes, i'm actually using brads msq as a starting point. No changes affects the movement of the ICV. It is flat out not working, the F-Idle wire shorted due to a bad solder(ya i know).

I suppose it's possible that the Fidle circuit on the board is hosed. I say scope it and see if you have any kind of life there at all.

I scoped the fidle megasquirt output. It showed no life, so I need to figure out how the f-idle circuit is setup on megasquirt. Someone come help lol, wiring diagrams give me a headache.
