Jack's O2 Mod

Installed in minutes today.  Can't wait to get out and try it!

This mod is intended to reduce the throttle surging of the 1300 at low speeds, particularly in conjunction with intake and exhaust modifications.  This "module" is a simple resistor that fools the oxygen sensor (located just before the catalytic converter on the stock muffler), into thinking that it is running a little more lean than reality.  Ideally, 14.7:1 A:F is what the ECU is expecting.  Jack's Mod makes the ECU think the output is leaner than 14.7:1. The ECU in turn tries to compensate for this "trick" and bumps up the amount of fuel, thus enriching the mix a bit to eliminate the surging and backfiring.

More details later.....
