Well, last night was a bust when it came to trying the GM mod on the Supra ignition. I finally finished helping my neighbor with an old service truck he had that was running rough. Ended up replacing his EGR, MAP sensor and timing it (it was off by 4 degrees). Luckily, before I went home I stopped at my "local" library and picked up some light reading material before I start wiring anything.

Won't touch it tonight as I'm taking my kiddo to her first hockey game (Seattle Thunderbirds), so hopefully Wednesday or Thursday I can tackle it.
