Ez-efi

[carbondaddy]

So.... how is this setup working out? I can't seem to find very many actual user comments. Thinking about putting it on my 434 sbc.

You can read my "not so EzEFI" thread. It does work pretty good, but it is not as EZ as the magazines make it out to be. Plan on an ignition box. I could never get mine to consistantly idle without one. I do have my working pretty good now, but it still has issues transitioning from cruise to idle, expecially when the AC or Fan is running.

Check on the posts from Greg Weld. He is using one.

Thanx for the info. I checked out Greg's thread on lateral-g.net and although he's having good results, I am looking for feedback on the system complete with the FAST throttle bodies. The Inglese manifold sure looks sexy though...

having some issues with mine - i keep getting an o2 code, but the car runs great. clear the code, and the car runs like crap. 496 bbc with a small cam, 10.5:1 compression, made about 420/420 hp/tq to the wheels with a holley 850 on it.

it's things like this that make me think that staying with a carb is a good idea.

turns out mine was a simple issue - just had to re-run the power wire to msd box.

I was starting to think the same until I looked around some more. It seems like the only ones that reply on here had negative results, but there are lots of positive results out there. So, I just took the plunge and ordered up a system. In a few weeks I'll be able to give my own feedback. Fingers Crossed

EZ-EFI worked great on my 410 AMC engine in my 3200# '79 Spirit. The 750 Holley double pumper was set up for road racing and was crap on the street. EZ-EFI was easy to set up,works as it should,idles at 1200 rpm (same speed as carb), cranks instantly with one turn of the key, and hauls ass at Road Atlanta with better throttle response off corners. Street usage is very smooth and response is better than a carb. I have owned this car for 24 yrs. and this engine has been installed for 7 yrs.

Carbon daddy, which system did you buy and why?

Carbon daddy, which system did you buy and why?

I went with Fast EZ-EFI master kit. Mainly because it is a complete system including fuel pump and lines, which I wanted to change anyways. I can use my stock gas tank, intake manifold, and billet HEI ignition. I will add an MSD box though. It is inexpensive compared to some systems. It is a simple install compared to most others. And it has the hand held programmer/display which will give real time info as well as the ability to change parameters easily and on the fly. I don't want to have to drag out a laptop or have someone else do programming changes or have to ship the ECU away for changes. I know it is somewhat less high-tech than a sequential system but it is close and better than a carb.

I'm just finishing up an install for a friend of mine. We used the EZ-EFI master kit as well and a sumped tank from Ricks. I just fired it up for the first time last night without issue, set the target idle and let it run long enough to get up to temp. It seems a lot crisper than the Barry Grant it's replacing. Hope to drive it this evening or the next to see how it does under load.

Jeff, how does it work??? Inquiring minds want to know!

[carbondaddy]

Ya, what tiger said, and what are u installing it on

[JeffT]

I haven't had as much time this week as I thought. I did mess with it last night for a bit, let it come up to temp again and then drove it down the street and back, maybe half a mile or so. So far so good, it didn't die/stall/hunt for idle etc... I plan to change the spark plugs this evening and go for a longer drive and see what happens.

Putting this on a 474 Pontiac in a 77 TA.

Jeff, how did the test drive go for you?

[2KWIK4U]

I would like to know too. I would like to put it on my zz4 crate engine.

[MonzaRacer]

dont knock Megasquirt either, in lots of ways its severely over looked even if you have to use a laptop or net book.
I have also added fi by using GM EFI computers and going to Moates.net and buying computer tuning parts.
Another neat thing on specific systems like using GM stuff is that parts can be bought in just about any time, any place.

[JeffT]

The test drive was fine, I only got to put about 5-6 miles on it. I did notice that it seemed flat when making sudden throttle changes so I bumped the accel fuel up a couple of points and that helped remedy that condition. I didn't get to do much else as the guy I was doing the install for took a deposit on the car and pretty much the next time it drove was into the back of a transport truck.

I just installed the EZ-EFI in my '77 Camaro. It is working out well so far. I was able to get the idle set at 850RPM with the IAC right around 20, which is what FAST says is the optimum figure. It is starting and running great.

I did a full write up on my blog.
