Default Upgraded ms1 to ms3 couple questions

So ms3x...

rewired for sequential spark and fuel.

Upgraded my ms1 to ms3.

I removed all my mods and moved them to the ms3x.

I attached a log of me cranking and the msq i'm using. I used the MSQ from frank's site. I made some adjustments though to account for my car being a 1.8 * having 1000cc ID Injectors.

I don't hear my fuel pump priming. I jumped fp to ground though and still wasn't able even get a hint of a start.

I set the dead time to for my injectors to 1.070 and changed my required fuel to 3.0.

Otherwise the msq is accurate. Any thoughts?

I got tach back and what not. I;m still not able to start the car though. As mentioned I am using frank's msq for 1990 slightly modified for my 1.8 with 1000cc injectors.

can anyone confirm that the correct dead time for my ID injectors is 1.070 and the required fuel is 3ish?

Also I noticed in the ignition options/wheel decoder settings the number of coils is set as wasted spark. Is that correct? Since i'm running sequential spark should that be set to single coil or coil on plug? Are there any other setting I should consider?

I'm running toyota coil on plugs.

if you're running seq. spark, then no, it should not be setup for wasted spark.

you can do wasted cop or cop.

there's about 1500 other settings you can consider.

I'm running this for my sensor input MS2-Extra Miata 4g63 Manual

Brain you mentioned something about reversing the polarity on my opt circuit. Could that be causing my issues?

I'm confident my wiring is sound and all that. I'm unsure about my ignition setup and my tunerstudio settings. Please point me in the right direction.
