Affordable Fuel Injection

I was at the Detroit boat show yesterday and came across Affordable Fuel Injection's booth/table. Pretty cool stuff. They basically sell a retrofit throttle body fuel injection kit that can be used in a marine environment. The guy I talked to also said that they could covert the proprietary ECM used in the marine industry to a OBDII compliant solution that you could use a standard OBDII code reader on. Not sure what exactly all that would be involved but the guy sounded like he knew what he was talking about and had experience with Offshore go fast boats.

In these days where companies are providing tunes for new model high end performance cars, one would think that tuning or converting a tune from our proprietary ECM to an open standard would be very possible. Got to admit it would be nice to be able to read the codes without having to buy a crazy expensive tool.

I like fuel injection. If I had an older boat I’d consider it.
The picture shows an O2 sensor. Seems like this might not be that easy to install in the dry part of the exhaust manifold.

Getting a dry O2 into a wet exhaust at an affordable price has not been done yet. So, $1500 bucks and you still need to come up with an O2 solution.

Just saw they list SBF as well.

When I was considering doing this I was looking at Doug's Naughty Girl which doesn't use an O2.

At one point in our conversation the guy mentioned that the 02 sensor was optional (it's also listed that way in the link I provided) but I didn't dig deeper into it.

If my carb was shot or the wife was having issues starting/running the boat this would be high on my list as a possible solution.

Hard part is you can get a brand new Quick Fuel marine carb for half that and if you tick with quality gas and stablize you can get decades of reliable service.

If there's no o2 sensor then how would the ecu know what the afr is?

you could make a spacer to go between the manifold and elbow that would allow an oxygen sensor access to the dry part of the exhaust or Affordable fuel injection sells one for $275, I think

There are open loop systems that don't use an O2, like Doug's boat.

Affordable Fuel Injection

Open loop fuel injection will not meet the performance of a properly tuned carburetor. I could rebuild a carb five times for the price of fuel injection. That said, a good fuel injection system would be cool.

I was talking to a few engineers about these types of system and for one reason or another they always end up getting fouled by water vapor getting back to the O2.
