So what your saying is I won’t have to make small screw adjustments when a shark farts and the wind changes from the north to west?

Once yoy have fine tuned your settings will it maintain AFR?

We have ran it on multiple flat water freestyle ski. Afr is place in pipe and isn't bothered by oil,,, and yes no more fuel screws!
It would make a lot of sense to not use a wideband sensor for this application, as it would almost certainly not work with the water in the exhaust, and likely wouldn't last long with just the oil, and your list in the initial post doesn't mention one, and it's kinda weird to refer to one as "AFR"....all of which makes this post not very confidence inspiring.

The Afr would be put before the water or in the freestyle application in a dry pipe. And an wide bamf is not bothered much by oil. They have been being used in the two stroke snowmobile for years.

More importantly, how does it survive water and leaded fuels...
Afr is not included with the kit as it isn't needed. Just is another plus of a stand alone ecu, but Afr would be place where water isn't. So dry pipe or if using a oem mani there is a nice location right up front before water. Ledded fuel isn't an issue. .also the wide band would oild be needed for ease of tunimg then could be taken off for a cleaner looking set up.

It would be open loop without a lamda sensor, which is how a lot of performance vehicles are programmed, after being tuned with one in place. One would just have to get a solid baseline tune for all potential environments and variables....which isn't easy, nor quick. More power to ya if you've got that working solid!

Did you use the wideband sensor to generate the base maps on the superjet/B pipe?

The facebook link is not working for me, is the video posted anywhere else? Youtube maybe?
