EFI Systems
I think I'm going to switch over to EFI this winter. It seems that Holley has a new 8 injector throttle body (sniper) that will support up to 1200 hp and FiTech has a system for 800 and 1200. Both have the ECU mounted on the actual throttle body for really easy installation. Has anyone ran the FiTech? The only downside I can see is that you have to run the O2 sensor all the time with the Fitech. The Sniper hasn't been released yet so the info is semi limited on it. I have dry exhaust so I'm not really concerned about the O2 issue. So any input on this subject.

That was why I asked, are the return ports factory? I don't have them on my tank. Also I know to be coast guard compliant there are some requirements for return lines. (not trying to be safety police, just mentioning it).

If you already have a strong electric fuel pump and a return line both TBs are $995 for up to 600hp. Holley you can lock in a map where as the Fi Tech is strictly closed loop. When I spoke with them a few months ago the only issue with marine use was the O2 sensor getting wet. After playing with my wideband and seeing how much the mixture varies just from the time of day I'd go closed loop if that's an option.

I cant believe that it wouldn't take but a simple software change for the FiTech to be able to lock a tune in like the Holley. Anyone have a friend in the company and can get them to make the change? haha

Innovative makes a bung extender that dramatically protects the bung. I'm running a wideband and if it survives the season I'm going closed loop next year, but I'm keeping my wideband working in the other header to monitor things. If the FI sensor craps out I can use the other one to get home.
