For the CIS folks: added pressure switch

I took the easiest possible route to get a tad bit more fuel and I'm pleased with the results. I wired a pressure switch (set at 3.5-4psi) in parallel with the full throttle switch on the throttle body. When the switch closes the computer sets the lamda ratio to 75%, giving you more fuel and ignores the O2 sensor. Acceleration is significantly "stronger" when the switch closes.
Kevin K. has previously mentioned using pin 11ish to bump the ratio to 9x% but that would involve crawling under the rear seat and fishing some wires.
Whenever I'm in the mood to fish wires I just have to look at my bathroom that I'm upgrading....
