That's easy, Daytona Sensors CD-1 Marine ignition. Completely programmable, has idle speed control for those of us with big cam and start retard. You can tie timing to boost levels, you can retard timing by a set amount based on an input. 2D and 3D timing controls. I run 93 octane, but if I have to get marina gas I can flip a switch and retard timing 4 degrees. CG certified. I had an MSD marine version and you had to buy a start retard module for starting which killed your idle control I ended up locking the distributor. It had the plug in modules for rev limiter and advance was totally mechanical. The really big deal is the idle control. It will advance timing to maintain idle speed when you put it in gear. It's night and day different from the MSD, the boat idles like a dream now and docking in adverse conditions is no longer a challenge. My boat has never run so good. I kept toying with the idea of switching to EFI for idle control. The Daytona Sensors is so good I will never go EFI. I'm in Northern Michigan and I boat from May to mid to late October so it's a bit chilly. The water temp in May is still in the 30's. I have a custom 1000cfm 4150 carb without a choke, 2 1" spacers and a single plane high rise intake and with this ignition it still starts like EFI when it's cold. Best part is I found it online for $460 for the box and coil.

I got it from Pit Stop USA. Just checked their site and itís now $625. Didnít realize what a deal I got. Either way knowing what I know now I would pay whatever it costs. I was actually thinking about getting a cam sensor and a Microsquirt and do an LS type system. Now that would have been expensive.
