So after putting the tremec behind my car a few years back I'm looking at adding injection to my car. I understand fast has a off the shelf system however I'm trying to save where I can. If one can obtain intake , fuel rails, injectors, throttle body, tps, and an IAT for reasonable would Megasquirt 2 be a sufficient ECU? I have a volley annihilator ignition that allows pretty adequate ignition control so fuel only might be all the control I need although ms2 allows ignition control as well. I realize I will need to change my fuel system as well. Looking for suggestions on both fuel system example surge tank with walbro pump using my existing system to feed it vs a complete rebuild, as well as ecu suggestions or anything else I'm missing here. Thanks in advance!

Have you seen this? This is redmist's build

Who wants to Megasquirt, full sequential fuel/ spark a 68 charger! This Guy!!

I hadn't seen that its more complex of a build then I originally planned but very nice

we can do your intake and fuel rails. and you can get a 4bbl throttle body that has the tps, iac andsometimes the iat. your most of the way there.

megasquirt will easily do what the fast and other systems will do it just depends on your budget and how much you want to put together.

Just sayin'....

Redmist's build is very nice. Mine is somewhat similar but I used a FAST XFI controller. At the time I started my build the Megasquirt was batch fire only and no spark control. That and the fact that I wanted someone to speak to if/when I needed support. The new Megasquirt is a far cry from the original and of all the systems is probably the best bang for the buck but regardless of which way you go, it will be at least $2k by the time you are done. Most systems use the standard GM sensors etc. so they are cheap but don't skimp on the fuel system. I looked at a surge tank system but in the end, I built a custom fuel tank with an Aeromotive A1000 pump. The surge tank idea is great but I didn't like the idea of another tank as the only place I could really mount one was behind the grill up front.

You say you already have the spark control so another way to cut out some costs is to look at a batch fire system. That eliminates the need for a cam sensor although the Jeep sensor Redmist and I used is cheap.

Ask lots of questions and do a lot of reading to familiarize yourself with the different systems and what each offers and above all, have fun with it.

That craigs ad is tempting but i think i found a whole package throttle body and injectors. As for the other setup a few questions,
1 Is anyone manufacturing the bushing for the Jeep CPS?
2 how are you all making the crank trigger setup work i seen redmist bought one from a member.
3 Will MS2 handle all of the stuff you all are doing?
4 I have a locked out distributor and its currently controlled by my Holley ignition so Im assuming i could just use that to run the MS whats the disadvantage in doing so?
Very nice tank setup That gets expensive since im not an amazing fab person though!

1: Don't know of anyone making them. I made my own.
2: I used an MSD crank trigger.
3: When I was researching, MS1 was the only version around. I know the MS3 does most everything the XFI does but I'm not real familiar with the MS2.
4: I also am not familiar with the Holley ignition but for street use, I can't see any advantage one would have over the other. The only downside would be that you would need two different programs and plugs to modify fuel configs and then ignition configs. With a controller that handles ignition and fuel, it's a one stop deal.

The fuel tank is important in any FI install. Initially I used a regular fuel cell with foam mounted in the trunk but soon found that when the fuel level dropped down to 1/4 or less, it was pretty easy to uncover the pickup and since FI has no real reservoir like a carb, the engine would stumble and often stall going around a cloverleaf at speed for example.

In my opinion, the fuel system, proper wiring and good tech support are three of the more important things when installing an EFI system.

1. we sell the jeep cps to mopar distributor bushing for both big and small blocks.

2. megasquirt can decipher a variety of standard trigger wheels you just have to mount one and a sensor and then configure megasquirt to use it. make sure if your welding it that you get the missing tooth placement correct in relation to your sensor.

3. ms2 should be able to do what your looking for. I don't think it has enough drivers to do coil on plug ignition.

4. no ignition control through megasquirt. that's the only drawback to not using the full computer control. not really an issue unless your running boost of planning on squeezing every last MPG out of your setup.

My buddy Bob makes some awesome injection systems, I know he has done RB's...

The new Mopar Action is covering this. Richard says stay tuned for part two for the wrap up. Hopefully, the final coverage for the install happens faster than the one for the front suspension, from like two years ago, that has never been finished.

MS2 will do your fuel and spark(if you want it to). Nice thing about having the MS do your spark is you can run more advance at idle, yet have it retard timing during cranking. Plus extra timing during cold start warm up, etc. Not familiar with what your holley system all does but I would consolidate it all into one system if I were you.

MS2 is batch fire, which would be fine for 99% of street users. Edelbrock sells two different port EFI intakes as well as fuel rails so your fabriation needs will be minimal.

If you don't mind the look, you can weld a sump onto the bottom of your tank and use a walbro gsl-392 external pump. I think those will fuel to about 550-600hp if memory serves.

CK i think the mopar action is essentially a copy of the buld on dodge charger the above thread but i havent read it yet.Turbo Daytona I'll Likely go MS2 it also has a self tune feature i believe. My Holley ignition is this Ignition It's currently setup on the factory electronic dizzy locked out and timing computer controlled. I do like the idea of MS controlling it all but i dont know if there are enough drivers on the board as mentioned before. If i go with the 392 walbro ( I already have a sump in my tank) and upgrade line and regulator that should be sufficient correct? Im currently running 3/8s aluminum and i know it wont hold the 40+ psi to the rails but is it sufficient for the return to the tank or will it need swapped as well?

Gdonovan I'll keep an eye out for your build as I'm looking to do something very similar. Picked up the bolt on stuff today.

I'm going to be doing a MS3 simiar to redmist's on a small block with the super victor efi. LSX truck coils + 36-1 crank wheel + 5.2/5.9 magnum distributor with the rotor chopped off for a crank sensor.

I'm using the holley 4150 flange polished throttle body. That thing is a great deal. 1000 cfm and has an IAC, TBS, and IAT sensor already on it. really a nice piece.

Got my Aeromotive Phantom 340 to put in a stock tank today. The drop in kit is for sale on Amazon for 429.99 right now which is cheap if you look around. Supports 825 EFI NA HP so it will take care of pretty much anything.

I've done it. I converted a single plane manifold (Edelbrock Torker) adding injector bungs, used a lean burn distributor, Edlebrock elbow/adapter and 90MM Holly throttle body with a megasquirt 2. It worked great. If you're interested, I still have the intake and fuel rails which I would sell as well as the throttle body and Edelbrock elbow adapter. I switched to a hemi and pulled that engine and it's sitting on a engine stand. My hemi is also MPFI. I'd never run a carburetor again.
