Well I haven't found a whole lot of people using these but dad just bought one for his camaro. It will be replacing a 750 dp.. ill be sure to post results

 

It is relatively new. Would like to see results. I like the way the throttle body body looks for the MSD and FAST better than the holley. but if I had to buy one id go holley because of holleys history.

 

The salesman told us the only problem they have had with these are if you go returnless and drive on days that are 90 and 100 degrees the fuel will boil in the line. In which case adding a return line would solve.

He drives his camaro less than 10 times a year, maybe this will change that?

 

almost all efi should have return.

 

He is going to the track tomorrow to see what it runs with the carb and then swap over. I am going to summit this weekend and will pick up the ez efi from fast as I would like to do a comparison.

 

Yea mint deal, I want to buy one also. Keep us updated!!!!!!

 

I have been interested in both the MSD and Fast units, some hands on info will be helpful.

 

The atomic Looks so much easier and Faster to instal than the FAST setup. But who am i kidding sometimes the easier ways just dont last.......

 

I lied I'm most likely buying the msd also. There is like 5 connections total. And the throttle body looks sooo sexy lol

I like the idea of controlling timing also. Dads will be returnless and mine will be with a return

 

Curious to see how it goes. A friend wants me to swap into an Atomic EFI but two grand is alot of $$ to throw around today.

 

I agree, I will be very upset if it runs like crap. As with a regulator and fittings with the cost of my walbro 255 I will be at roughly 2500 for the kit

 

here ya go:

The first system I looked at was the FAST EFI. however then I saw the Msd Atomic Efi, and watched the SEMA reviews and all that Jazzy stuff.... The good thing is.... Theres more than one system to choose from!

 

I ran into a snag, I got 3/8 to 6an instead of the right metric fittings to tie into the factory lines

 

after i installed the walbro 255 it didnt work so i pulled the tank back out and am installing a fuel cell and external pump. i have all the wiring done for it now. just need to install the wideband and finish the fuel set up.

 

I will be installing the fuel cell tonight and hopefully be starting it up for the first time. Hope I didn't waste 3 grand for nothing

 

lol yea i hear ya. dont forget a possible Start up video lol

 

Keep us up to date.

 

Well I got the hole cut for the fuel cell but I have to make a frame out of tubing for it, I got the fuel lines ran and the afpr installed. I just am needing to mount the cell all the way and its good to start...
I work 4 days on 4 days off ,12 hour days so its hard to work but a hour or so after work..

The suspense is killing me and I will get a video of the car running for you guys

 

a video would be great.

 

Maybe pictures.

 

I got it all finished last night but it wouldn't start, I think that its flooded so I'm picking up new plugs today and hopefully it starts right up.

Btw I do have spark and fuel...

 

Well I talked to msd 3 times today and they have no clue....

When I called jegs and told them I was bringing it back they said " oh great another one"

It would run for 2 seconds on starting fluid then die.

Sad to say but there won't be a review since its going back. I'm really depressed that I wasted my money and I had to cut the car up for the fuel cell

 

Thats the atomic right? what the hell. Well Jegs is usually very good with returns/warranty stuff, even if the manufacturer warranty is out, jegs will sometimes extend it and provide a full refund of your purchased price.....

 

Well I got it back on and it runs great... for those not watching my other thread... I had water in the gas from a tree knocking a hole in our shop roof last month... the gas wouldnt light with a torch.


I just need to turn the pressure up as I'm running out of injector at wot

 

lol yea that'd do it.. Glad you figured it out!!!!! did you contact jegs? i wonder why they are having returns.....

 

I couldn't believe it was the gas lol... I'm glad that I left it sit overnight and the gas on the floor didn't evaporate

 

but they still said oh great another one...ive never been a fan of anything msd besides their plug wires...

 

We have a msd box, coil, and distributor on every car in our garage(4) and have never had an ignition problem

 

I have heard the new ones are 50/50 if you get a good one or not. Are they still coming from China?

 

i still have to get rid of the smog pump, it sounds like an exhaust leak. just a quick video of showing how easily it starts. even cold it starts just as well

 

sweet sounds good

 

Will this unit run off a Walbro 190? I've been looking at something to replace my TBI unit for years now. And with the whole timing thing being internal to unit that's just one less thing I have to play with.

Anymore opinions on it after a week with it?

 

"Returnless" systems have a regulator and a return line near the tank, only 1 line is sent to the engine bay. Im personally not a fan of the system.

My distributor/wires/coil have been fine, but Ive eaten 2 Digital 6's. First one was the ground was to the frame, apparantly they want it to the battery. Shorted that one out. Next one got wet from rain. Heres the kicker, its in the battery tray with the hood on. Not exactly alot of rain, just a little. Pulled them out and put a friend's version of the 6AL in the trunk, been fine since.

If the fuel pump can support the pressure required by the combination of the motor and system, than yes. Obviously a 305 is going to have less fuel demand than a 383.

 

Thought id do an update, the more i ran the car the worse it would run. I had to start it like 10 times to get it to stay running and it would often die on decel and stops. I had black smoke from being rich coming out of the tailpipe and was eventually slower than it was with a carb on it. I took the system back. I would not recommend this to anyone. I would like to try the edelbrock one but dont want to waste my time again. Go with one that needs tuned

 

You should have bought the Fast EZ EFI.It has a lifetime warranty and is self learning.

 

So is the msd atomic, it has 6 hook ups, msd just needs to stick to ignition products

 

wow it is that bad ?

 

I have yet to be impressed by either system, yes they run and seem to work, But we have seen significant drops in both HP and torque on the dyno. They are poor responding and tend to over fuel and are very finicky to get them to self learn. If you want EFI spend the money and go with a proper multi port setup.

 

i have yet to have any of these issues with mine and i'v had it a bit more than 2 yrs.
as for the over fueling, how did you figure this? on mine the learning process was quick as anything i'v seen. and BTW, the ez has a system that goes perfectly with the HSR, MR, TPI systems.

 

i couldnt agree more, if you are thinking about spending this much money the fast xfi would be a far better bet or the holley hp efi. something that has full tuning abilities.

i was not impressed at all with it. you dont see much info online about these systems and i hope that people looking into this system for their car steer another way.

thanks,
justin

 

The 8 wideband sensors's we have on our dyno told me this. I do all our EFI tuning on the dyno. It over fueled horribly, and we have to drop the fuel pressure drastically and basically trick the computer into learning. Horrible system. I would never sell another yet alone use one.

 

How much drive time was on the system?

 

My Holley Avenger TBI runs great even with little tuning. It runs on 21psi of fuel. I also have it controlling the timing. It also turns the radiator fan on or off wherever I set it.

 

The car had probably 300 miles on it. Which should have been more than enough

 

thats strange, of all the systems i have seen i have yet to see a issue like that unless the accell fuel was set way on the other side. i have mine set at -6 and the AF is around 13.8-14.0 area (its been a while)in the WOT and 14 in cruz and idle areas. mine sings like a canary with no fueling issues.

could have been something underlying within the motor that triggerd that.

 

The motor has about 400 miles on it so that is most definetly not it

 

13.9-14 is a bit to lean at WOT IMO. 12.0-13.0 is where I aim under load.

 

My Avenger's factory presets are 14.0 idle, 14.0 cruise, 12.5 wot.

I set mine to 14.5 idle, 14.2 cruise, and 12.5 wot.
