FAST EZ EFI/Multiport

[Vegas69]

So, you're happy?

[GregWeld]

To steal Al Morenos style of statements...

Happy... is not a big enough word to describe how I feel about this new set up.

It's the best damn thing in the whole wide universe and maybe even the galaxy!!

Even better than twin pops and sliced bread?

I've been digging that FAST EZ Efi setup for the FFR as well. Heard a lot of good things about it and it seems reasonably affordable as far as EFI goes.

John ---

I only used the ECU and the wiring harness they sell for "multiport" systems. I didn't use any of their fuel pumps or their throttle body etc - since I have a combo of "parts" for my 8 stack.

I'm now using an intake from INGLESE - which is based on Webber IDA's - but they've cast in a large common plenum in the valley. I'm using Imagine Injection billet throttle bodies... and then the FAST EZ EFI as I said.

For me -- it was like going from a Windows based computer to the Apple. You buy an Apple - you open it up - turn it on and use it. You never care about the settings etc because you never have to know about them. Now -- WINDOWS on the other hand - you have to know all the little secret boxes to check (or uncheck) and where all those little windows are - and you have to know or understand all manor of computerese.... SO the Accel Gen 7 is like the window crap -- you need an expert and a dyno - and you better know what you're doing... and it's going to take multiple days/trips to get it right. The FAST EZ EFI -- is a 20 minute wonder - you plug it in - answer the questions - start it up and go for a nice drive. When you get home you're all done and have a smile from ear to ear. Simple. Done. Happy.

Come on Greg don't hold back let us know how you really feel ! lol I'm glad you are having good luck with it . Its always nice when something works as advertised.

GregWeld,

I am looking for information on how the eight stack works without an IAC valve (new to fuel injection). How is idle quality and how does the engine react when the AC is switched on?

I saw your post on FAST where you described a problem you were experiencing recently and you mentioned not having an IAC. The FAST tech seemed confused (I assume these are the same folks giving tech support for the Inglese system with the FAST controller...)

Thanks!
Todd

I ran an individual runner setup with FAST, but I ran a remote IAC setup. Worked awesome. Mentioning it in case you weren't aware of the remote mounting options.

Todd,

I don't have an IAC - don't need it. Motor was built with EFI in mind - to wit - we did a custom Crane cam with a wide LSA (114* I think) to get some vacuum and smooth the idle a bit. Another thing with 8 stacks that people don't understand is that you have ZERO "reversion" (pulses inside a normal open/common plenum manifold)... so an 8 stack will "eat" a bigger cam and tame it a bit.

The problem I was experiencing was I couldn't get it to idle down.... and this was AFTER I had it running super! But it - as most of these things seem to be - was OPERATOR ERROR.... I had gotten the stacks out of sync! From side to side they were off.... IT was completely my fault. I had disconnected the side to side linkage - and adjusted the idle in the meantime - and then failed to reconnect the side to side linkage = and then the more I messed with it the worse it got! UNTIL -- in the middle of the night -- I had an AH HA moment! Re-sync'd the TB's --- with the manometer -- and all was smooth as glass once again.

NOW for your other questions RE: A/C -- This isn't much of a load on a motor that is making a bunch of TQ and idles at 950 rpms.... I also have a "loose" TQ converter... 2800 stall -- so when I drop in gear - there is no discernible RPM loss. This motor made an AVERAGE of 478 foot pounds of TQ from 3200 rpms to 6000... so I think that's why the load of the A/C compressor just isn't a factor. I also run electric fans so there's no load there either. I get a bigger rpm "reaction" when I turn the stereo on! I'm serious! That puts a momentary load on the high output alternator. I use a SPAL PWM fan controller - and that is designed to not turn the fans on when you switch the A/C on... it waits about 20 seconds or until the trinary switch reaches a preset head pressure. I think this also takes that A/C load off the motor... as most hammer the alternator with the fan load (radiator and the cooling speed fan).

I drove to Portland on Wednesday just because it was supposed to be 90+ degrees.... this EZ EFI works so dang well -- it's just amazing. This morning when I got up (down there) I decided to change the cruising A/F ratio from the 14:7 I was trying out -- trying to see how it'd run a bit "lean"... and simply plugged the little hand held in -- changed the cruise number and drove off.... The motor seems to "like" a bit fatter A/F and the torque seemed a bit flat with the 14:7 I tried on the way down. The beauty of this is that there are only 3 numbers -- Idle -- Cruise -- WOT. Just pick one -- and the rest is all done for you. No tables to mess with... nothing. GAWD -- the thing is so simple and it just works!

BTW -- My idle doesn't vary 25 rpms.... watching the dash tach -- it doesn't move. Watching the hand held programmer -- it varies 50 at most.
