Thoughts on the FAST Ez-EFI system??

[GregWeld]

I have TWO cars with 8 stack EFI.... a pretty nasty little 406 in a heavy '56 Nomad / 700r4 / 2600 rpm stall converter / 3:73 Ford 9".... and a 383 / 5 speed / '32 Ford Roadster...

The 406 uses the Inglese intake manifold with Imagine Injection billet air valves... the 383 uses the all Inglese manifold with their air valves. BOTH cars use FAST EZ EFI and both cars run flawlessly... fire off instantly... cold drivability is "fire it - drop it in gear and drive off".

Given your location - and your statement that there isn't much available or around... provided that your motor is "built" to be EFI friendly (a wide LSA cam - providing good solid vacuum signal) I'd think the EZ EFI would be the right system... simply because it self tunes.

We can argue about how perfect the A/F's are all day long... but I'm LIVING PROOF that if you balance the air valves (using a meter) and you set the basic settings of the EZ EFI correctly (in other words - you actually have to READ and FOLLOW the instructions)... You'll be able to fire it up -- warm it up - drop it in gear and go drive - within 30 minutes - your car will be running great - and the next time you drive it - it will drive better and so on - until the A/F's meet the settings you selected. There are only 3 A/F settings -- Idle - cruise - WOT. There is acceleration fueling that can be changed... but most wouldn't really need that and you'd need a dyno to really see what your changes are doing.

So with the EZ EFI -- it's ONLY going to control fueling. The timing of the engine is standard same as a carb -- in other words -- just a good distributor, curved and set for initial and total timing properly. Frankly TIMING controls the performance of an engine way more so than the "perfect" A/F ratio.

BTW -- I don't sell this stuff - I have no vested interest in any of it - tuning or products. I'm just a long time EFI user that has real world actual use "opinions".

Caveat -- EZ EFI is not for radical cams etc. So do your homework/research on what is a good engine combo for EFI before choosing your ECU. If you need to run radical profiles -- then you're going to need a tunable system -- and a real good tuner and lots of dyno time.
