Has somebody tried the dynojet CMD marien ? And can you put it on a 502mpi

Not sure. Looks to be like a "boondocker" or powercommander go between device. Cant change your limiter with it, definite drawback.

In fact I think it is a powercommander rebranded. I doubt they will have anything for my 575. This definitely looks interesting for the average joe.

I had used the unit all last season. Works on all Mercury EFI stuff. It will only change air fuel ratio and nothing else. The unit will adjust your afr to what ever you want and works as claimed. Instructions are terrible and you will have many calls to the tech department to get it set up correctly. Once done the unit worked flawless and is pretty easy to use. Jeff Wurl

Jeff, did you try the self tune also ?

Yes, I had the cmdm and the wideband 2 autotune and their digital gauge. All worked fine. You can not see the digital gauge in bright sunlight. Jeff Wurl

Are there any other fuel mangment system is the market ? Either then dynojet ? That has self-tune?

Ttt

i have one for sale in the swap section, and yes, it works with merc EFI

it works as an interrupter on the injector plugs.

can set AFR based on O2 plus any 3 inputs. (map, RPM, temp)
