The fuel injection made it in yesterday. It would have been here faster, but USPS tried to deliver to a business on Saturday. No big deal.

My initial impressions are very good. The build quality of this box is almost on par with an XFI box. Great connectors that give a rewarding pop from vacuum when you disconnect them, heavy gauge wiring with good insulation and quality connectors.

For $1300 this kit far exceeds my expectations. The simple fact that something as capable as MS3 is housed in this box, makes it an unbeatable deal.

An overall shot. The harness is very well laid out and it uses OE connectors.

Here are the 6 wires that it needs to run...off the top of my head it is Fuel pump, constant 12v, switched 12v, o2 etc...

This may be easier to get working for me than a 6AL....no joke.

Looks good! Where can you mount it? Can you put a pop can or a $1 bill next to the box for size comparison?

Does this system run your fuel injection and the ignition? Also is it fully programmable from a laptop? It looks like a really nice setup. I would be very interested in one if it does all that.

I'll get some good pictures tonight or in the morning.

This runs it all. Fuel and spark. No external modules or extra stuff. It comes with about 15 extra wires for boost control, nitrous etc but none are critical to the n/a functions.

The Deane guy from the Hot Rod article used the unisteer rack set up. I thought that had a bad review?

It does, but when you look at the cutting they had to do to the steering box mount, it may not have worked any other way with his combination of components.

I can't speak for his choice of parts, but I like bolt in parts for my car. The ease of install for this motor and the relative ease of the EFI will be great.

By far, the most complex part of the car (I use that term loosely...its not really complex) is the fuel system.

Carter P4601HP for my lift pump. I ran it as a single fuel pump before and it doesn't have a problem pulling fuel from the bottom of the tank.



Feeling into the BCBroncos Fuel Accumulator. This will give me a 1qt reservoir of fuel at all times. This was a big part in making this car effective without a full race fuel tank or a heavily modified stock style tank. Its just a very affordable surge tank, props to wade (uhcoog1) for giving me this idea...



A simple GSL392 Rotary vane inline external fuel pump. Good for 600hp all day long.



A corvette fuel filter/fuel filter regulator. About $27 by wix, and keeps my engine bay clean by leaving all the extra plumbing back there.



This will go up front through my 1/2" stock style fuel lines in stainless. I'm going to be blocking off my return line for now, it's not needed at the moment.

I'll be feeding into a set of stock 6.1 fuel rails. Nothing fancy. Good for 600+ hp. KB retains these for their 2.8L blower kits.



And finally a set of SRT4 stage 1 fuel injectors.

Here is a breakdown of what hemi injectors will do...

Stock 5.7- Bolt ons on a 5.7
Stock 6.1- Maxed out on a head and cam car
Stock 6.4- +1 for a head and cam 6.1, not a huge improvement.
SRT4 stage 1- Entry level max effort 6.1 and basic 426. Also suitable for stock displacement with a small forced induction build (vortech includes these with entry blower kits)
SRT4 stage 2- Built 426 with small nitrous or boost.

Above that, you can get any of the above rebuilt from any number of vendors up until about 1000hp. After that, something like Injector Dynamics ID1000 or ID2000 is needed to have excellent drive ability with that much power.

I forsee my car getting a second GSL392, a forged 6.1 and some sort of forced induction. I've got a Vortech Kit for it, but I really want a Magnuson/Kenne Bell kit..just for the sound really. I'd be happy to lose 100hp over a centrifugal blower for that whine.

Are you planning on going speed density or running a mass air flow sensor? Does the MS3x from them have the map daddy 4 bar sensor? I have MS3X for my chevelle LS swap and the dual map sensor is nice as it can be used to correct for altitude changes by comparing the static one and the engine map sensor. I have heard that the new MS3 Pro uses an external MAP

The 3g Hemi is built around Speed Density. I'll be using a factory sensor in the back of my 6.1 intake.

The ECU will make judgements based on the MAP sensor and the intake air temperature sensor. Here is a breakdown of the features on this box.

Ok thanks I know some use a GM MAF sensor. The newer card type one is able to read a huge amount of flow and has been succesful with boosted apps.

Good to see another option for our cars. I was just reading up on a kit Mopar Action did an article on a year or so ago. Required the crank to be pulled to install a tone ring. Yikes. However, it allowed the use of GM ECU and all the OBDII diagnostics too...

Now that I see this, I don't know what route I would take.

7 in x 7 in and the mounting tabs are sliding to allow staggered placement.

The only perk I could see that the Delphi based systems have above this is the tuning aspect. There are so many more tuners out there. That being said, if I didn't want to ever tune it myself....I'd be running a hotwire kit with a factory Mopar ECU, get a Diablo Programmer and have someone knock out a tune via email in 3 shots.

Between the autotune function on this (as well as XFI) along with the megasquirt community online, my choice was easy.

I'm not one of those people to care about having ford or chevy parts on a mopar, but I can't see why someone would spend $2000 to have LS1 stuff on their car when there are better and cheaper options out there...unless you identify with the reasons I stated above.

Thanks, that may squeeze in behind the kick panel. I'm gonna have one in a month or so myself.

the datalogging with the ms3 is pretty awesome too which makes tuning that much easier, I'm really impressed with the latest adaptations that have more robust connectors and look more like a "polished" product.

I wanted to mount it in my glovebox but my car leaks....well...like an old car. I'll end up mounting it in a semi-weather proof container somewhere by the AC box.

I wonder if EFI source would build a system out of the new MS pro? That unit is designed to be able to get wet and mount in the engine compartment. I really like the kit form of MS that has come out. That should make it alot more popular with people
