i was thinking of adding an EFI to my 454 in the future but still want the look of the carb so was thinking the EZ EFI system by Fast (http://www.fuelairspark.com/ezefi/default.asp) so you guys think it wouldn't be worth it compared with a full EFI conversion?

Hey guys,

I am currently testing a fairly inexpensive system which comes with very high recommendations.

It is a batch fire system as it fires 2 injectors at a time. The only advantage to sequential port is very little fuel economy gain, and a slightly better idle.

So far I have installed this very easily. I am re doing my ignition with an MSD solution at the same time.

My results to date are that it is easy to install, seems very easy to program, and is inexpensive at $1950 for the whole system including the tune, wideband O2, harness, and software. There's only 5 pages for tuning, which greatly simplified it.

Yes, it does NOT have all the bells and whistles of a Fast or BS3 but in the world of a distributed motor, are those really necessary? For a distributor motor there is no need for crank timing, AC Cutoff, etc.... This is a fairly basic system that works very well. I am testing it because I won't sell anything that I haven't tested.

I'll go through the process below.

Mega squirt is junk. Everyone I know who installed one wound up pulling it out. Save your money.

MSD Install. Again the hardest part of this crap is finding a place where it will all fit.

I put the MSD box under the battery box, I will have to modify the battery box to accommodate the MSD. I went with the frame rail, as it is covered by the wheel well and runner board.

I managed to get 3 of the 4 mounting screws into the MSD box, think I'll just run a serial cable to the top.

Here's some shots:



You can see the ECU on top to the right.

This is where the ground from the battery ties to the frame, I grounded everything there, you can see the yellow connectors through the wires.



This is off the positive side of the battery, and is stock. I picked up the battery connections from here:



Here's the relay all hooked up:


Here's the wheel well back on so you can see how everything fits:

I had to modify the battery support based on where I mounted the MSD. It was an easy job, I trimmed as little off as I had to. Not sure about the structural integrity issue, I'll look at that when I put everything back together as it's the last piece to go in.

Here's some pics:

If you have any questions about this, feel free to PM me. I don't know how it works yet, but will very soon. the biggest holdup at this point is waiting for a harness for the MAP that MSD did not include. As soon as I get that I should be able to fire it right up.

So far, it seems to be a decent system, I'll know more when I fire it up.

No, a Mega Squirt is a EFI system controller or ECU. There are quite a number of different systems on the market today

Fast systems used to be Power Pro, at least I think it was but I have a friend that uses them exclusively drag racing Hondas. He gets tons of power after setting it up on his dyno. I think any conversion from a carb to efi is definitely an improvement. The look is sometimes what's most important unless your really hard on racing the car you wont notice the difference.
