I am about ready to dive into a fuel injection project. I don't know much, but I am willing to learn. So far, after doing a little research, I have come up with that it probably doesn't matter which system I want to use, it is all about how easy it is to learn to use. My motor is too performance built to run the self learning only systems. I will not need to have all the bells and whistles, but the higher end systems have better memory and faster computing. I have talked to Rich at Fastmanefi.com and he is steering me towards the Holley hp system, with FAST xfi as an equal. My decision. Sounds like the Holley is used more and has more support, related to its affiliation with racing sanctions. The Holley learns faster, but is harder to navigate. The FAST xfi is easier to navigate, slower to learn, and is an older software system compared to the Holley. Chryco has recommended SDS efi due to its handheld tuning, and easy to use software. It won't like my low vaccum at idle and I have to use it in Alpha mode. It doesn't use the standard IAC idle system, and is very limited production, but customer service is great. Both Holley and FAST use the dual sync distributors. I will also need a new ignition that is compatible. Both systems are able to connect to my transmission computer. I will use a Aeromotive Phantom 340 fuel pump and have a 3/8" return line. For ease of use, I want to buy a complete system from one company. All plug and play. Fastmanefi.com has a good maps for a similar engine and similar intake system so I don't have to start from scratch.
I don't need any advice for systems that will use throttle body efi. My plans are to bolt on the F&B 6bbl with MPI in an edelbrock 6bbl intake. But I do need advice on each of the Holley and FAST system as to the ease of use of the software usage. I can only assume the bolting on all of the hardware will be the same between each system. Any feedback will be greatly appreciated. Oh yeah, is it worth the $$?
