RKcarguy - watch your local laws for now, WA has many Eco-measures in place that are kind of swap-proof... In fact, right now, in Spokane, Washington is the leading edge of the anti-phosphate movement. (Green dishwashing detergents).
Since when do you need to remove the stock prom on an obd1 board?

OP - don't waste your time, you won't get much out of it if you're going for fuel economy.
