67 twin turbo dart

Good thread on digital rising vs digital falling. Digital Rising vs Digital Falling?

what’s the purpose of the 170 degree threshold for the boost control?

Thank you for that. I am not sure, that was set up before I got this setup. Just did a search the ecu won't let boost be active or controlled below 170* or what ever you set it at, probably a safety thing so you can't just get in and jump on it on a cold start.
