Default MSD Atomic EFI Install- Not so simple/straightforward, but a DIY project.

So I haven’t see much in the way of an install thread on the Atomic EFI (or much talk of it on this forum) so I thought I would be the first idiot to post a build thread. I am pretty much done with the install, but haven’t had much time to do a write up because of my work schedule. So, in saying that, my postings will be in parts as time comes available but I hope to have this thread finished in the next 30 days since I am still trying to fine tune the system. Not to throw in any spoilers, the install has been pretty damn frustrating (hopefully this thread will solve those frustrations) but the end results even with very little tuning leaves me speechless…. I can’t wait to put the car on a dyno to do a comparison; which will also be included in this thread.

Let’s get started. See my signature to see the specs of the car. The engine is about 1.5 years old.

The most import part that all build threads should post is….. The total COST(s) (as of 9/12/12):

- MSD Atomic EFI - $2,219.00 (525 hp base kit with fuel pump) PN#2900
- MSD 6a Ignition box – Free (MSD was running a promotion with the Atomic for a free 6a)**see note
- MSD Dizzy Pro-Billet Ready to Run - $271.99 PN#8479 ** see note
- MSD Rotor Phasor - $31.95 PN#84211 ** see note
- MSD 6ft Harness Extension - $42.95 PN#7786
- Profession Products Crosswind Intake - $236.95 PN#54026
- Fuel Sending Unit 3/8 outlet- $43.25 PN#FSU28 (Purchased at CJs)
- Fuel Pump Block off plate - $10 (bought at autozone)
- Misc Parts - $50
- Paid exhaust shop to weld the 02 bung in my header - $20

Total so far: $2,926.00

I already had a:
-Flamethrower II coil which is compatible with the system.
-MSD ignition plug wires.

I will explain in this thread why I bought what I did and will also explain what NOT to buy as I had to send some stuff back. I will also be putting my old setup on Ebay for anyone interested.

Notes:
** These parts are needed if you intend to use the Atomic EFI to its fullest. There is no work around that is recommended. 99% of the problems I have found on MSD's website is because people use work arounds or other vendors parts.

Well.... FAST EFX's new advertisement says "Don't make an Atomic mistake"! lol

I was considering on buying the Powerjection 3 but have been pretty disappointed with all my Professional Products buys. I further backed up my suspicion with their products when I bought their intake manifold for this build.

I would look at my total costs for someone that doesn't already some of the parts (MSD dizzy, MSD 6a box).

You could have saved me some bones if you did a thread on the Powerjection 3! Was it as "straightforward" simple bolt on and go?

^Iskwezm- That Price had to be for the Powerjection 3 without the fuel pump kit. It's $1,800 for the full blown kit.... Still cheaper though. I think the MSD Atomic is $1,900 without the fuel pump kit.

Looks good... you will love it when you get it tuned! I wouldn't trade mine for any other set up.

I got my COMPLETE(with fuel pump) kit for $1460.00(plus the 80 lb injectors). i have zero complaints about it and install time was about 10 hours total including running to the auto parts store and taking breaks.It wouldve been faster but i had to find -10 to -6 AN fittings from my previous carb set up. other then a 3 wire hook up, bolt on the throttle body,wire fuel pump and fuel line, turn the key and go. i did have to do my own tuning because of the turbo.

my buddy as the Fast EZ EFI and he hates it and he didnt even pay for it.

So your running the Powerjection 3 in your 65 which is force fed.... That's my big gripe with MSD at this moment is that the Atomic only supports N/A engines. MSD is supposedly working on this and has been making subtle improvements (they just added MAP sensors a few months ago). You must have some connections to score a deal like that especially with the 80lb injectors..

For all those wondering - I am currently trying to fix the Idle dieing as soon as you lift off the gas or in my case disengage the clutch. After that's solved I should be good to go.

Hoping to have part two out tonight.

I had a similar problem with mine. You have to adjust the idle screw while reading the idle counts on the handheld. It needs to read below 15 or something like that. It is covered in the manual( I read it after I installed it)

thats the main reason got ths kit is because it works with blowers or turbos and no other kit supports it yet. I didnt have any hookups. i bought it from a retail shop that specialized in Pontiac parts.

Ok, So I have not crapped out on this thread. I fixed the problem above but now have a totally different problem of which I have yet to figure out.

The issue above was fixed by adjusting the Idle RPMs and related Idle timing. MSD sets the timing on this unit at 10 degrees BTDC which was too low for my car. The car ran flawlessly once idle timing was around 13.5degrees btdc and the driving characteristics were dramatically improved (could cruise at 1,500 rpm without backfiring and the engine just ran smoother). As for the RPMs, MSD calls it a "target" RPM which you set for idle. I had to set mine at 1050 rpms to take care of some of the stumbling and dieing. Although it is set at 1050, it idles at 875 - 950 rpms; thus the "target" rpm. Raising the RPMs at idle was the only suggestion that was given from MSD to solve the dieing when releasing the clutch. Through reading the the MSD forums, I found that adjusting the timing would help too. On that note, it appears that there is a major disconnect with the MSD and instructions in regards to how to set the timing on your engine to allow the Atomic unit to control timing. See the MSD forum for all that discussion. If you have to call MSD, there is a tech there with a 66 mustang and the Atomic unit installed. He seems to be one of the most knowledgeable techs there.

As for my new problem, once I got the Idle RPMs and timing set I took the car out for a drive. While cruising for about 20 minutes, the engine went haywire and died on me. Come to find out, a piece to install this kit, the Phaser rotor, came loose in my distributor and advanced my timing to 30 degrees btdc. fortunately, the system shut the engine off before any damage was done. This is a common occurrence and MSD recommends that you use some lock tight on the retaining screw (however, you have to read their forums to figure this out. You will see a lot of issues with the phaser rotor on their forums regarding this.) Anyways, since that has happened, my timing is all screwed up. I thought I had it fixed, but for some reason the MSD unit says my idle timing is at 22.5 btdc. but when I slighting put some pressure on the throttle (not even enough to raise the RPM), it goes to 12.5 btdc and it idles like crap too. So I am not sure if it is a part malfunction on the Atomic unit or what.

If your thing about going with the Atomic EFI, you may want to go to MSD and read the forums....... If I could start all over, I would have going with the FAST EFI.

More to come on this thread.

I'm following this....

I am halfway building a 428pi and still don't know what I am going to have for an induction set up. I want EFI but not sure which one. Your thread here has me leaning (no pun) towards FAST EFI.

Can you let us know any efficiency numbers, like mpg or hp/tq increases over your carb system?

James

I will definitely provide you with efficiency numbers when i get the car dialed in and with no issues occurring every weekend. I do know that the car does get better mpg and has more power. I can feel the HP increase and my gas gauge goes down a lot slower. Ill try to get numbers here shortly. as for the Dyno numbers, the last time I went to the dyno, I spent 4 hours trying to solve issues at $150 an hour so I want to make sure that I don't go through that again.

As for the Atomic EFI, don't get me wrong but some people have had good success with the system. However, if you bought the product, you would be able to tell that MSD rushed this thing out the door and are still trying to solve issues etc. FAST EFI is known for creating EFI fuel systems and computers etc..... They have a solid product from what I have seen and heard. Plus I like Fast's ad in Car Craft.... It says "don't make the Atomic mistake"

Ok..... New update. Based on my post from Dec 2 2012, and after about 8 or 9 calls to MSD, a complete update to the EFI system, and basically re-doing the timing aspect of the install 2 times, MSD said that there must be something wrong to the throttle body (which also houses the brains of the unit) and that I need to send it back. It's been there since the 7th of May, and as of yesterday, they were testing the throttle body.

The issue was the unit would no longer control timing on the engine. My post form December was the start of it and from letting the car sit over the winter, the issue got progressively worse. Timing would be set at 13 BTDC at idle and the unit would only get it to 4 BTDC. Add some gas and the unit would decrease the timing instead of increase it.... To me, sounds like a part malfunction.

The good news is that MSD pushed out a new update for the system that reduces the systems overly richness at idle and also now allows the Map other tuning abilities for force fed setups...... I did notice that the thee or four months of trying to get the thing dialed in last fall, it ran rich at idle and you could clearly see it on the spark plugs too. I hope that what ever MSD is fixing on the unit makes my experience worth the money paid for the system.

I'm looking for a procharger now too!
