The only major drawback to installing MegaSquirt is losing cruise control. My fifteen minute round trip commute is now an hour and a half round trip commute and 75% is highway. I was looking at aftermarket c.c. systems but I'm hesitant to spend $200-$300 on something that might not work or work as well as I'd like it. So it got me thinking, "would it be possible to wire up the factory switch and servo to the SMEC with power, ground, distance sensor, brake switch and possibly TPS and MAP and would it work?" I'm looking for input from people who might have a better understanding of factory c.c. and the SMEC or if anybody has experience with aftermarket c.c. systems that are currently on the market.
