Default FlyinMiata vTPS not working while engine running

Long time lurker, first time poster.
I'm running a DIYPNP v1.5 in my '91. Been running it for over a year with the Flyin Miata 'TPS upgrade kit for NA6' and no issues. Just a few months ago I added a CX RACING turbo kit and Monza catback, again with no issues. The car still runs fine, but I have been trying to hook up launch control and I have noticed that I do not get any values for TPS with the engine running. I am not sure if this is a recent development, or if it has always been a problem and I just never noticed. The car does not have AC, and I did not wire the PNP for it. To enable launch control, I jumped 1v to Input2 In, then Input2 Out to Flex (as described in a blogspot post). I was trying to test launch control by setting the limiter to 2500, soft limit at 200, and TPS for 10%, but as I pressed on the gas the TPS needle would range from -.3 to 1.2 but not move higher as revs increased. With the engine off but the vehicle powered on, I can press on the gas and watch the TPS needle sweep through the ranges on my laptop, tracking the exact amount of throttle I am giving it. I tried re-calibrating and saw no change. I am assuming this is what is preventing launch control from working, since throttle position is not reading high enough to enable it. Has anyone experienced anything similar?

Is it wired correctly? It is not plug and play.

Turns out I just wasn't hard enough on the gas. Thought my clutch was going and it turns out launch control was kicking in while I was driving. Later I got it to work in my driveway. Case closed
