Not Odyssey engines have the lurch. If yours doesn't then I would leave it alone. I think the generic kit has been phased out. The steam kit has the capability to work with wireless tethers as well as older wired tethered engines. The main difference in the diesel kit is it has a connector to convert the 6 pin power/motor connector to the Cruise Ms 4 pin connector.
Before ordering make sure all of your engines have modular boards. Most made after 1999 do.
You can go to electricrr.com and download the manuals for these before you buy to see what is involved.
