when you plug in the jimsitm to the MS. run a wire from the second trigger position to pin 32 of the ms3x.

it's pretty simple, want me to take a pic and show you?

OHH OK! Haha sure a picture would certainly help, if you wouldn't mind. I'm not exactly sure where the 'second trigger position' is that you are referring to.

here, i have my 2nd trigger jumper going to iac1a for all my non-expansion installs. so i use a jumper from iac1a to pin32 (cam in) of the expander to bring the cam signal in when using the stim.

Should I have all of those jumpers installed? Cause I don't have a single one.

you just need the one.

those were useful back in to day for ms1 and ms2 installs where I could test outputs, I've just never removed them; I suppose I should.

Since everything is running off the ms3x card they are useless, and I need this: JimStimX Expansion Board - Assembled DIYAutoTune.com

Oh ok then hah. I haven't had a chance to test it yet due to school. But I ordered another pot from diy. Hopefully I can get around to messing with it tomorrow and have it going by weekend.

Added the jumper for the 3x cam in, but it's still going crazy. About to replace R56 in a couple minutes.

New pot R56 installed and it's still doing the same. Full counter clockwise, I'm geting .04v across the resistor. and 6-7 turns, I'm getting .09v What is going on here? Am I'm measuring the right place?

I'm assuming you'd want the black lead on a ground and the red lead on the spot where you have the black above.

Yep, that's what I needed to hear. Got that set to about 2.8V and the max I can get out of R11 is 2.25V at R17 on the expander

Didn't have a lot of time today, but it seemed to have fixed the sync loss issue. Which I'm super pumped about. I still cant get the idle sorted out without it hunting, and it still has fluttery RPM deceleration.

1.1 Beta 21. It's probably because my idle settings aren't right. Do you use PWM closed-loop?

Flashed the firmware this morning, fixed the WUE, and now the thing is running amazing! I been driving and tuning all day and I'm so excited that it is running so well now. It is getting poopy gas mileage though

Is the middle red LED supposed to stay on? Mine is on sometimes, sometimes never lights up, and sometimes flashes

Middle LED (assuming you've not re-purposed it for something else), is a WUE indicator.

I.e. when it's on you're in WUE

Ok that would make sense. And I'm assuming the right one is accel enrichment. Tried to do a couple mid range pulls and it feels kinda sluggish after 3k

Well now my tunerstudio hangs up on start up. It checks for updates, then says loading fonts or something and then it just hangs up. Tried reinstalling and updating java.
