I think I've picked up in other threads that this is normal but I want to be sure. WUE on the TunerStudio interface and the WUE led on the MS box both seem to be functioning proper relative to CLT. But I have no IDL led on the stim. Like I put in the subject, the MS is configured for a stepper IAC. Is what I'm seeing okay?
Thanks for any insight! Doug

Doug,
Yes, that's the appropriate behaviour for the stim when you have the code configured for a stepper motor IAC.
For testing warm-up enrichment on the stim, you can reconfigure the IAC as a PWM, and set the values from 0 to 100%, and you should see the LED dim and brighten with large temperature changes. That won't tell you much about the stepper's behaviour, though.

Re: IDL led won't light on V3 MSII wired for stepper
Set the values under FUEL SETTINGS > IDLE CONTROL? I didn't see where I could specify anything from 0 to 100%. My apologies if this is obvious. I may be showing my newness here.Lance wrote:Doug,

On a side note I did jumper pin 20 to 34 as I have seen in other posts that this is a method to test the IDL led on the stim and it does light up. So thats good.
Thanks for the help Lance!

Re: IDL led won't light on V3 MSII wired for stepper
Doug,
See the "Idle Steps" and "Idle PWM Duty Cycle " table described here: http://www.megamanual.com/mt29.htm#ed
The same physical table (i.e. the same locations in memory) is used for both PWM and stepper motor logical table valves, but the values aren't generally compatible (PWM runs 0-100%, steppers run 0 to 300 steps). I believe the defaults are for a stepper motor. If you change the idle valve type (under 'Idle Control/Algorithm') you generally have to change this table's values as well.

Just ran that test and acheived expected function. Thank you very much Lance!
