Anybody using FAST EZ-EFI 2.0?

[GregWeld]

When done right - these systems can work pretty dang well.


I agree with you Chris... I'm not a fan of the plastic LS stuff.... yet I put one in Gwen's new '33... because it fits in there - and is light weight - and is reliable. I learned long ago that sometimes 100% "everything perfect" sometimes doesn't work - and a guy has to go with what will work/fit/afford/looks right etc.

I have posted on the other forums (some of you may have seen my post along with my you tube video of the 2.0). I do feel the system is very temperamental or effected by noises, but once I got all the "knowns fixed or addressed it seems to be performing well. I have ran it with nitrous several times and it performed great. I recently went to the track, and had some issues I need to try and work out. Issue being while on the trans brake then launched the car fell on its face, and would pick back up. I could not really tell if it was getting to rich or leaning, because I could not watch the AF gauge. Next day went on a side road an from a dead stop went WOT, at the same time it started to fall on its face I noticed it was leaning out. Now I can add more accel fuel which should fix that issue. Now at 45mph going WOT with nitrous,,,its perfect and responds great.

Also here is a site that you can also go to and see some common and not so common issues. Just do your research and know what your getting and what to expect.

Wow! There's a lot of folks over there struggling with EFI. It really does show that there's more to it than "bolt this on. answer these questions, drive". I read several of those threads about the noise filters and faulty units but also fuel delivery problems, distributor problems, ground problems... like you said, "know what you are getting".

I'm not worried, I'm sending mine to Sun Valley to get installed...

Installation is EVERYTHING.... and most "first timers" just don't get it right. There are a lot of "don't do's".... It's the don't do's that kill people.


The new SV shed should be ready for operation in about 3 months.... then "bring it on". Bring your mountain bike - and your dogs... A guy can't just work on cars without a break!

LOL



There's some "inside" knowledge about the EZ 2.0 that I'm not free to share. But I wouldn't buy that unit right now. And if you do - make absolutely certain it's not installed in the engine bay. And not anywhere near the MSD (or similar) ignition box.

But it has to have an MSD to function. I would have mistakenly wanted to group all the electronics together and make it tidy.... then pulled my hair out (If I had any) trying to figure out what was wrong. I see how some of these guys get in over their heads. A lot of very simple/innocent mistakes could be made and the system never perform...

If and when I decide to FI my BBC, I'm making darn sure I've got my "injection for dummies" handy... and GW on speed dial.

Have had a Fast XFI 2 system fitted to my Mustang for 6 months it has been great . Engine is a 433 Cu in FE high compression running a F&B Throttle bodies Tripower manifold . Car fired up first turn of the key no issues must admit though FAST install instructions could be better especially being so far away and with different time zones makes it difficult to communicate . I agree that the most important thing is ensuring to get the wiring done properly good power and earth connections.

I see some say "do not mount inside the engine compartment", mine is mounted inside the right fender well in front of the firewall, down inside the small hole that kinda goes behind your kick panel area. Further away from the engine than if mounted behind the firewall. If not mounting inside the firewall area is due to electrical noise.. Well under my dash area I have more electronic interference things, like Dakota Digital Dash, Power windows, door locks, alarm system, radio, more gauges, push button start box, A/C, power antenna, remote exhaust cutout box, multiple nitrous controls. MSD I mounted behind the driver kick panel (so its on the opposite side from the 2.0 computer), and I'm sure I'm missing a few. So my point is that its not really any better by mounting it inside if you have this going on, or at least I don't think it is. Where I have it mounted is about as far and isolated from anything else (but the unit itself), and its out of site. My engine bay is very clean, the only wires that goes from the unit to the engine is basically the wires to the TB.

I still wish FAST would have done something better to help protect this unit from electrical interference. Even though I have it running pretty good, if something happens its harder to track down. Just like the issue with launching and it going lean, I can only start guessing where to start.

As far as the XFI, someone mentioned having.. Different than the 2.0 as far as some of the issues people are having.

Again I just think it could have been protected better, but I'm happy with what I have (because its mine now). I have at least 1500-2000 miles on te unit, but everytime I drive it i'm constantly wondering if I'm going to start getting the notorious "Comm Error" from it and it shut down on me. So far I have not seen that from it since the second week of driving it, and fixing or re doing things that I thought may be the cause.
