[QUOTE="Stumpalump, post: 433844, member: 13140"] Gotta ditch the O2 sensor on a wet exhaust. Best way to do that and keep fuel injection is with a Mercruser (Mefi) controller. I run a Chevy LSJ 2.0 supercharged motor out of a Cobalt SS on race gas in a sand car. The race gas is leaded so I can't run an O2 sensor either except for when it's on a dyno. Solution is to use a Mercruiser (mefi) controller and custom wire harness. Problem with that is its not as easy as stripping an old boat. Best is to call an outfit like CBM and buy it and harness with a tune in the computer to start with. Chucking on a simple carb is a heck of a lot less time and money plus you don't have to pay for dyno time or risk blowing it up. [/QUOTE]
