That should be sufficient, I dont even run extra grounds more than to the OEM ones myself.
Can you get a datalog and composite log of the loss of sync? that would really help to figure out the cause.
we can see if it's the cam signal, crank signal, or anything else...
edit: Oh I see you have already, I'll have to look when home.

But here are some logs for you fine gents hope these are better
I also have a few new questions.
1. What do you all use for idle control? And, could you screenshot your settings? I am currently using PWM closed-loop, and it would idle way high because it was constantly pulling air through the IACV, so I capped both end and it idles normal, except really low during warm up. Low enough that it will die if I try to drive before it warms up some.
2. With my idle VE on, it idles around 10AFR, and with it off, it wants to idle over 18AFR. I'd like to know you all's settings with this as well. Is it just as simple as taking away fuel from the idle VE map?
3. More settings I would be ecstatic for you all to help me with: Acceleration enrichment. Also, it goes extremely lean when trying to cruise with little gas or just giving it little gas in general. It also bucks when I give it a little amount of gas. I will also attach a log of this.
I would love to supply any settings of mine that would help. I appreciate all of the help I pulled my ECU and brought it to school with me to check over the innards and fix my LEDs, which I somehow put in backwards

Took my MS apart today and hooked it up to the stim. Having weird problems with the tach input. Turning R56 until i get something and the tach signal go absolutely nuts. Data log says constant sync loss reason 38 (4g63). I also can't get any voltage above .17v on R54, turning R56. I am measuring voltage across the resistor right? Pos. probe on top leg and neg. probe on other leg of resistor?

I'm looking at the composite logger but again, idk what the heck I'm looking for. Just a bunch of lines going crazy. I don't have the stim for the expander card, could that be a problem possibility since the expander controls the cam input and such?

you just need to send the second trigger into pin 32 of the db37 of ms3x.
then when you sync and turn the rpms up, you can see if the top green line drops off or the bottom blue line, then you know what resistor is causing the issue.
