So anyone try the MSD atomic EFI yet? - 03/21/12 03:07 AM

It looks like a well thought out system but I have doubts about replacement sensor availability and pricing?

Has anyone tried it on anything yet?

I would love to give it a try on my boosted car to see just how well it would "self learn". Too bad it's $2300

I am waiting to see if anyone has tried it out too as I am very interested in the system. Definetly seems very well thought out. I saw in one of the new issues of hot rod they had an article about it in the new products section, and they said to keep an eye out as they are going to do a test on one pretty soon. In usual hot rod fashion, it should be a good write up of what to expect.

I read about some EFI system recently that looked exactly like a carburetor. The fuel boals were only covers, there to hide the EFI components. Is this the same setup?

Yeah pretty much is what you are describing. Everything is hidden in the throttle body, TPS,MAP,injectors, etc. What I like is it uses pulse modulation to regulate how much fuel it needs, so you don't need to modify your fuel tank or run a return line.

I checked that link. This is not the same as what I read elsewhere. the setup that I recall used what looked like Barry Grant fuel bowls.
Similar to my Speed Demon carburetor.

There was another thread on this here at Moparts a few weeks ago...and I shared your concern with parts availability and pricing.

I will be putting one on my 73 RR 340 as soon as my body guy is done with it. I want to run E85, which is common around my area, but not across the country. I will be adding their dist and a 6AL box, with this setup i will be able to reprogram it to run reg gas or e85 with just a hand control switch, I talked to MSD quite a long time at SEMA and sounds like this is the perfect setup for me.

That is one of the draw backs of the EZ-efi. No E85 compatability...I was hoping to see that as a software upgrade, but so far nada...

How about Powerjection III? http://www.professional-products.com/EFI_3.php
I have the returnless 70029, but not yet installed

That was my plan, but at SEMA FAST guy told me they have put it on the back burner for now.

Wonder how long till the knockoffs start washing up on shore.

I cannot afford one at $2300 but if there were a half-priced alternative it might be hard to resist.

You can DIY with GM junk on the cheap... it's just a lot more work to set up

If I did this, I would love to have an E85 option, though it's not essential in my application.

At Summit, the 70026 complete kit is $1683.95. (Not sure what the system differences are between 70026 and 70029)

Maybe all the GM parts worked on his eyes, check out the fuel filter...Chevy speed secret maybe?

Heh, it's very poorly documented and probably pretty old. I bet a MegaSquirt II could control all of those components easily with a lot of community help for the ECU. A MS+junkyard part EFI setup could probably be done for several hundred dollars easily. Heck, forget hacking on crappy GM TBI stuff, get a Magnum intake manifold and its associated top-end hardware and you're already halfway there for a small block.

Maybe a little off topic but not totally. With the expense of the EFI (which I am exploring also) how much will the system add to the value of the vehicle? If you already have a $20,000 ride and add either the EZ EFI or the MSD will the car be worth $2,000 more with the EFI?

Not sure, but maybe you are talking about Retrotek efi? that was out a few years ago. Horsepower TV put one on a 66 or 67 charger and one of the magazines put it on a car. All I remember is that the magazine guys took it off because they had some issue with it. I think Retrotek is the same as the professional products. While Atomic and EZ efi look sort of like a carb, that Retrotek looks exactly like a carb.

I'll be looking forward to your review. I just got a thing from JEGS that they are giving away a free 6A box when you order the kit.. FYI.

Re: So anyone try the MSD atomic EFI yet? - 03/22/12 03:44 PM

I talked to MSD yesterday and will need Dist 8534, rotor 84211, 6A box (and yes send in rebate for it) and the Atomic kit2910, I already have fuel pump and lines done already. My warehouse is having a sell March 26-28, so I will be curiuos how much I will save. My car is suppose to be back the end of April so it won't be till May till I can put it on.

As far as replacement sensors -
Most every aftermarket system I have investigated standardized on GM-type sensors, meaning the sensor resistance curves are comparable to what GM used. There are a plethora of variations in the aftermarket regarding wiring connectors, mounting threads, etc, but if you're needing a replacemnt part ASAP you'll probably be able to get something that would work, or could be rigged in temporarily, at a parts store. Looking at a part for a 1990 GM __________ is a good starting point.

And for any home-brewed JY EFI system, unless you get it all for free you better plan on spending at least $500 minimum. A new 45 PSI pump will run $80 minimum, fuel lines and fittings aren't free, you'll want new sensors ($50 easily) - it adds up quick. A junkyard ECU will be $50 minimum, too.

And there's a TON of info and upgrade parts out there for the GM TBI system, and even though TBI is frowned upon it still offers lots of benefit over a carb.

OK, sidetrack over...

Well went ahead and order parts today, Atomic efi, dist, coil and rotor, free 6A box, by rebate, save myself over $228. Suppose to get car back late April, can wait to install!! anyboby need a quikfuel E85 Carb!!

Cool. I look forward to hearing about your install, and the results!

sorry to dredge up such an old thread, but did you get your EFI up and running?

UPS will be delivering mine tomorrow! I am however still WEEKS away from having the car to the point where I can try to run it.

Re: So anyone try the MSD atomic EFI yet? - 06/11/12 06:07 AM

I installed it on my 440 a few months ago and I love it. Just answered a few questions and it started right up. There is some manual tuning that you have to do, but it is simple. Took the car on a 400 mile trip a few weeks after the install and had no problems. It was well worth the money, in my opinion. I did an in tank pump install with my kit.
