This system came up in another thread and to not take away from that OP's thread i figured i would start one on it.

So has anyone used any of these systems on Marine applications? Seem really simple, and you really don't need a lot of the (auto) bells and whistles that the Holley's and Fast systems have for marine use.

What are some of the issues that this system may have ? This Question is addressed to the guys on here that actually tune with EFI on a regular basis.

Honestly they don't tell you much in the description. Like "4 high flow 600hp injectors". I'm a believer in you get what you pay for.

looked at that as well...looks interesting...several make the same looking unit, not sure on their ECM and thats where all the magic lies...could be great though

Laptop software is available for advanced tuners site says. What capabilities it allows is not listed. Site looks to cater to people who want the ease of bolt on and go carb replament. However, the videos on their website show it in a blow through and roots blower application and reports say they run fantastic and idle smooth. I know my interest has been piqued.

I've only read positive reviews so far. I called and asked if they've done much work in the marine environment and they said the biggest hurdle was keeping the O2 sensor dry. I asked about locking in a map and disregard the sensor after tuning and he said no dice.

The have the basic bolt on and go system, or the "power adder" units designed for supercharged systems. I plan on playing with a unit soon. I'll post my findings.

That's too bad.

Yeah I wouldn't even consider a package that relies on O2 sensor data unless I was running a totally dry exhaust.

That was my biggest question. That sucks! I don't see why they couldn't add that to the software.

Anyone here use the Fast EZ system?

Very cool. What does it do when O2 fails?
