Default Diypnp 93 miata start but stalls instantly

I have a 93 miata stock besides intake and lc-1 wideband sensor
I got my diypnp assembled up and hooked it up to tuner studio started the car and it started up then stalls immediately i tried again and I've i give it gas it'll stay alive but runs pretty rough. I'm wondering why its doing this.

In the instructions it says INJ1 4Y, 4Z and INJ2 4U, 4V does this mean wire from the INJ1 to both 4Y and 4Z same with INJ2, or means i can use either one of them?

Also is it needed to remove resistor R14? is it just optional if I'm wanting to run ac?

only if you wired per the old instructions and dont have the MS control a/c idle up with the new firmware. R14 should stay in plce and you should be sending INPUT 1 into PE1, not back out to the harness.
