FI a Dauntless

I am running the 1bbl Holley projection on an evenfire :v6:

 

Does this MSD Digital 6-Plus need a distributor upgrade? I've been looking at the wiring diagrams and I can't see a clean way to wire it to a stock distributor.
Maybe I'm just a dunce.

:iagree:​

I've never upgraded an ignition before, but it seems like a good thing to pair with a new fuel injection system.

 

Warloch...did you switch threads from this one? I'm starting my research for a rock crawler project. I originally planned on buying a vortec 4.3L with the driveline, but I would prefer to install the megasquirt onto an extra 225 oddfire that I already have in my possession. I'm interested to hear how this panned out...does this continue on a different thread, or, are you still working on it?

 

You went away from the Megasquirt...any reason other than it's obviously more time consuming to come up with all of the parts? I dig the EZEFI and the Powerjection, but that price tag would give me a 4.3L Vortec with drivetrain, and Novak adapter for the D-18.

 

:iagree:

That's what I'm thinkin' too!

 

I'll be interested in what you do. I can't really commit the $$ for the kit install although it's attractive. I have the TBI from a 4.3 that I pulled before the yard here crushed all the older iron and also got snarky about pick and pull. I have stopped at the point of whether to put in a megasquirt which others have done or see if I can get the family "CFO" to pass the cost of a full kit.

Price will be the determining factor for the kit. which EZ-EFI kit were you looking at. They seem to fit without an adapter to the 225 manifold?

I really love the OF. always have and nothing sounds and pulls torque like it

 

Crack pipe idea: heads intake and ignition off a series 2 or 3 3800 (with or without superchager:twisted and tweak the ignition timing and injection to work with the different firing order?
Worlds first MPFI Supercharged oddfire???

 

I like that idea. I was going to FI my 350 chevy years ago on my Z car project. At that time before I found out about the megasquirt I was looking at stock GM ECU's. My idea at that time was to just take a aftermarket 4bbl manifold (I had purchased a Weiand unit to do the mods on) and install injector bungs over each port.


The throttle body was going to be a cheap affair with just a aluminum plate on the carb mount, a 90" aluminum elbow with another plate welded on that. This plate would then just mount your typical V8 single throttle body like off a multiport GM or Ford V8.

I'd then aquire from the wrecking yard the required sensor's and wire accordingly. With the mega-squirt available now it would seem the same sort of setup with a much more tunable ECU makes what I had in mind even better from a tuning perspective.

Of course like many, a divorce squashed all that idea losing tools, the car in question and much $$. I still have plans down the road to do this once we get somewhere I can work on vehicles again (in an apt, no garage eventually moving to land in Texas where we'll build me the shop I want).

While TBI is still better than a carb, it works rather the same and if you want IMHO the best fuel metering than hands down multi-port is the way to go. I'm pretty sure having the bungs welded welded in a 225 stock manifold wouldn't be super expensive although it would require someone that could probably weld cast iron. The injector rails are bought usually by the inch if I recall and its then a matter of putting in your injectors, finding the distance between them and drilling the injector rail in the appropriate spot. The injector rail is then bolted down to the intake to hold the injector's in and keep both O rings (top and bottom of injector) sealed.

I know I'm over simplifying this whole scheme and I havent addressed timing and such. I think on a 6 with the Megasquirt I'd go with three packs of 2 coils each to fire things. Then they would be fired from the appropriate timing wheel off the front of the crank, the distributor would then just be stubbed off and capped since it would then not be required.

Is this a cheapest route, in the end it usually never is, but I still suspect it would come in about the same or slightly cheaper than a TBI kit if your shrewd and learn to get bargins on everything at the wreckers. FI doesn't have to be complicated, once you throw off all the oh my GOD all this wiring parts away, the mechanics of it are ridiculously simple. Sorry for the long post, just tossing some idea's out there probably worth what you paid for it... R)

Ps: Here is a page for creating a fuel rail out of stock material:

SWEET!!!!! If you can, keep a list of parts and personal instructions. I'd buy the book on how to change mine over!

 

I contacted the Powerjection people about this about a month ago. They said that while their unit would probably work OK with the stock manifold, it would be better to use a 4150 sq. bore manifold.

That's the way I am going.

 

I think there are several of us who would do the same!

 

As for the pre filter, I assume you would be worried about getting enough flow through it for their pump. Seems like if the pump puts out 45 psi it would need to be able to "suck" that much on the inlet side. Just guessing though.
