Megasquirt fuel injection

[ZVOLV]

What kind of HP gains would one get by using Megasquirt? What are the pros and cons of this system? http://www.bgsoflex.com/megasquirt.html

Don't know if you'd realize any hp gains in a normally aspirated engine. Possibly if you're using the Megasquirt on something that didn't have EFI before. Where this system shines is in it's programmability. It will allow you to use bigger injectors in a turbo engine and therefore allow you to run more boost. It's the cheapest, by far, EFI controller on the market. I've built one and they're certainly not difficult to build. I've also got two bare PC boards for future projects, should I like how it works with my current project. There are a couple of people on this board who have them installed and running in cars. There are a couple more who have them built but, as yet, have not got them installed. "Ted the Terrible" has a picture of one in his ID file...

Yup. I built two. One is going in my '83 (my summer car) and the other is going in the '84 I'm driving every day. The '83 is all in pieces right now but it'll be on the road this summer. The '84 will get taken appart this summer. Jordan has one running right now.

I think you could definately expect performance gains. Just being able to fully tune the fuel system is worth a few HP. Also, the MS will support a sick amount of power. Anything from a few HP to over a thousand. That's tunability.

If you are replacing K-Jet with MS you will definately gain power just by eliminating the airflow sensor plate, also it will allow more precise mixture control improving power and mpg. Dan242tic

I am going to use it for a turbo app. So it programs itself? How good is it compared to other fuel computers out there?

No...you do all the programming. Well...most of it anyways. You set all the running parameters. You set up a VE table. You tell it what injectors you're running. You tell it what size your engine is. You tell it everything it needs to know. It will then run your EFI system. The chips come pre-programmed to deal with forced induction engines and they have an on-board MAP sensor. It's not exactly a plug and play setup...

[quote:08ebfb2d6a]How good is it compared to other fuel computers out there?[/quote:08ebfb2d6a]

The first comparison is price. For less than $200 you should be able to get it up and running. That's 1/4 the cost of any of the other systems out there. Of course, you don't build any of those. As I've said, I've built one and the quality of the board is very good. The layout is clean and assembly is relatively easy. If you can get by the assembly stage, I think you have a very versatile unit. As was said before, it can run everything from your lawnmower to your 1200hp drag racer...

A group buy on the PC board, chip and case is about to open. None of the other components will be included but there is a link to a electronics supply company (Digi-Key) that will order the entire package of components... Or, you can take the BOM to your local electronics supply company and order them piece by piece...

Good Luck.

I have it up and running on my car. Been running since October.

Runs good... Few incidents (nothing MS related, it was all MSD related).

I get ****ty milage when in boost. But its not blowing black or anything. I am running around 10psi now. No desire to go higher with gas prices.

I barely drive it anymore. Even though its my daily driver.

But I like it. Way nicer drivability than my NA B21F engine that was in there.

feel free to ask specific questions...

And no, it doesn't program its self. you need a laptop to do it.
