Montauk, very cool that you were able to drive the gauges with the ecu. I thought about that but I didn’t want to mess with figuring it out. I’m still using the factory style sensors and the modern sensors keeping the systems separate. Would have been smarter to do what you did.
On the positive side, I finished building my “motorsports grade” wiring harness. Took time to properly plan and route. I understand why people charge what they charge for these now.

Nice work. I bought the pre-made flying harnesses.

A big oops by me. I would have sworn that I had set my ECU to use throttle position and not MAP. Well, I didn't. I was looking into a setting that Haltech has for "MAP Prediction/Fuel Film Enable" when I saw that I had left "Fuel Load Type" set for MAP. So that's nearly 150 miles running based on MAP. The only problem I had was odd behavior at low speeds particularly starting from a dead stop. I changed to TPS and drove it about 15 miles with no low speed problems. But I did notice that deceleration could be a bit too quick. More settings to tweak.
