Sorry Bent Wrench I skipped over your post. I am going to post in MSExtra forum tonight but let me try to fill you in on my system. I need all the help I can get though I did get the tach signals working. I had to adjust R56 potentiometer up to 2.5V

When I do a MS install I use the MS Extra manual exclusively, mixing manuals can produce poor or unexpected results.
Also the Extra manual is very up_to_date.
I built the board 6 years ago using the build manual at the time (it was not very good) with the instructions from DIY Autotune's article on the Ford Probe/Mazda MX-6 with Mazda KL engine.

I don't think Mazda and Ford used the same electronics on that motor. So that may be throwing you off track.
These two do as Mazda built both.

Do you have separate crank and cam sensors or are they both in a cam driven CAS unit?
and
Are the sensors powered or passive?
(Optical, Hall, or VR?)
I have a VR crank sensor and Hall cam sensor.

Are you trying to use a "base tune" or are you making setting changes to the default tune?
Here are the changes I have made.
Set the following under Tach Input / Ignition Settings.
• Spark mode: Toothed Wheel
• Trigger Angle / Offset: 0
• Ignition Input Capture: Rising Edge
• Spark Output: Going Low / Normal for MS2, Going High / Inverted for MS3 It is critical to get the Spark Output Inverted setting correct, as setting this wrong can result in damage to the ignition module or coil.
• Number of coils: Single Coil
• Spark A output pin: D14 (MS2) or MS3X outputs (MS3)
Use these trigger wheel settings.
• Trigger wheel arrangement: Dual Wheel
• Trigger wheel teeth: 6
• Missing teeth: 0
• Tooth #1 Angle: 60
• Wheel speed: Crank Wheel
• Second trigger active on: Rising Edge
• and every rotation of: Cam
I tried but not go on the MSQ file here.
Now the current problem is that I have no spark.
Tunerstudio tach is working and it is synced.
I put a scope on the Crank pulse and the ignition pulse that turns on the igniter and the ignition pulse is only 2.32V that seems low to me?
I have been looking on the forum and will post there. The Name is the same MYTF
