Fast xfi 2.0
Has anyone tried using the relatively new FAST XFI system on a Ford modular or GM LS engine ?
Am considering buying one and running it - if its usable.
Any comments/suggestions that are physically possible (LOL) would be useful

Hi Rog
The FAST setup is two grand plus. I have no comment on its performance. Another system I stumbled accross the other day is the FITECH efi for about a thousand dollars. It appears to be similar to the FAST system. I'll wait for others to comment on that.
Cheers
Dave

Fitech is self learning. The xfi is stand alone. Night and day difference.

Self learning is crap read the reviews with a big cam. The xfi will run any engine you want. Just like oem.

I think I understand what your after as your are considering a transplant or crate motor. Also not trying to pitch the intake and injector system the comes on the engines.
In which case you only need the XFI interface and controller.
http://www.fuelairspark.com/fas/xfi-...yote-5-0lhtml/
http://www.fuelairspark.com/fas/xfit...6-currenthtml/
These to do come with several tables pre-installed and user selectable and just like the Holley/Atomic/FiTech and will self tune to some extent. Fine tuning on a dyno can be complied with but usually not required unless you want to eek out some extra HP.
Some folks feel EFI daunting and can spout a lot of rhetoric and "I've read this on a forum".
Personally I love Self learning EFI as I have an FiTech and won't go back to the Holley 4150HP at least on this car. I'm not qualified to judge the merits or failing of systems I don't own or have not worked on.
I'd check out the FAST forums and you will probably get the best 1st hand feedback there from real users.

You don't have a radical cam so self learning will work ok.

Possibly, I'm not sure as I don't have my build specs. I only know its a flat tappet. It pulls 9" of vac @ 15deg idle which seems to be its happiest setting for vac/timing -2 deg. So I'm using stage 4 for initial EFI setup which runs quite a bit better than the Stage 3 settings. Once I change the Intake manifold (Super Victor 4000-8500) to an (RPM 1500-6500) it should be mucho better for my needs.
I'm slowly debugging it here and there.
It would be great if you could link the reviews on Big cam and EFI self learning systems are mismatch. I may need to rethink my next cam profile as I'll eventually go to a Hyd roller.
I did a ton of research prior to purchasing the FiTech and read reviews on all the major systems tested by Hod Rod, Mustangs and Fast Fords, CarCraft , and others and I've never come across any warnings.
Now I have read here and there folks having issues in setup and tuning on every system out there but that is on the forums and not professionals. I typ attribute those to the same people having a hard time with their AOL email, having their Grandkids download apps for them.
Thanks in advance.

I have noticed from various forums the big cube big blocks with radical cams don't do well with self learn efi. We have a couple efi shops in az that won't even mess with the self learning stuff. And all these shops do is race cars with efi.

Of course those magazines will give good reviews. They are paid to play. You really think hot rod mag is going to bash a product. I have never seen a product revieved by these publications that does that. Only praise. Do a search here. There are many threads on self learning efi. Not saying they can't work but nothing compared to a multi port system.

Most in the end will ditch the self learning and go back to a well tuned carb. The Kirkhams have tried the self learning systems. Give them a call they will tell you their opinion on them. Every one on here who says the self learning efi works have small blocks. I have yet to read about an FE engine who has it work. Barry at survival Motorsports tried it on Anthony's fe. They took it out and went to a multiport system. It would never run correct. Avmaviator is Anthony's handle here. Look it up.

Km647 is here. This is the thread you want to search. Barry goes into detail how the self learning would not work. Gave Anthony credit for the self learning system and upgraded to fast xfi system. 13 page I believe. I don't know how to link it to this thread. Barry builds some of the best FE on earth.

On my last Cobra (462ci FE) I used the professional products "self learning" system that I picked up from a member here. Initially I was running a Demon carb, stout hyd roller and a PI intake.
#1 The self learning aspect never worked as advertised.
#2 Changed to an edlbrock streetmaster intake and the world became a better place. Apparently many TBIs don't like duel planes.
#3 That particular system was also tunable by laptop and some of their forum members were greatly helpful in getting my setup sorted.
#4 Once sorted it was great. Cold starts from standing outside the car, killer throttle response, mileage jumped by more than 25%, and I no longer smelled like gas after a drive.
#5 In the end I wound up with a system that still had the vintage look of a carb with the operability of a nicely setup FI.
Win, win!

I'd seen that once before on the intakes.

Pay no mind to the Summit reviews, Only 2 given on three systems all from the same person. Having fuel pressure sensor issues. Evidently had been trying to get this newly released system working for over 4 years. Maybe he forgot he already reviewed it and what PN he bought and what year it was and what his name was.....

Anyone on here with an FE that uses a self leaning system can chime in. Not small blocks but stroker fe's with radical cams. Where are you???
