ive seen 12a to 13b adapter plates for carbing 13b's, but not the other way around.

would it be possible to flip it around and use it on a 12a?

as for the gsxr tb, why not mount em all on top of a dcoe lower manifold? http://www.mazdatrix.com/pictures/racing/r9-4.jpg
the dimensions should be close enough to make it work fairly easily.

 

what is the fuel economy that they system will provide?

 

Just like a haltec it all depends on how you program it and how you drive it.

 

I can probably get some economy numbers. A friend with a street port 12A on a RB manifold and 50DCOE had a long road trip the other day and has been playing around with Vac advance (which is tricky with aftermarket parts). He has hooked in an ECU controlled bleed to switch vac out at idle. With only mech advance he was getting 24 highway, but that was only on a rough tune. I'll mail him

As for the 12A/13B adaptor plate. The one I have is reversable.

this is so freakin awsome, i hope it gets here soon!!!

 

You can buy a MS kit today. Its been proven that people with only half a brain can build it and get it running.

 

Dammit! Now my S5 setup isnt going to be unique anymore! Everybody on the forum is going to running around with s5 intakes!!

Aside from that, this setup will really give people a kick *** product. I love my S5 setup, now it looks like everyone else will get to experience why this setup is so awesome for a N/A FB.

VDI=FUN

 

what and where can you get this wonderful setup?

 

Hopefully by spring

 

where is this kit at??? and has anyone used it?

 

Not until I do it!

Got some feedback today. This is a 12A running a racing beat weber manifold and a 50DCOE carb with a megasquirt. rebuilt and street ported engine. On a 400 mile round trip, 80% of which was cruising at 75-80mph it was returning 29MPG.

This setup hasn't been dyno'd but is making seriously more power than stock, so I reckon that's pretty good mileage. It uses a control to switch manifold vac feed to the dizzy. This gives the smoother idle of no vac advance and 5MPG more with vac connected. As soon as the spark code is ready we should be able to push this some more.

To buy a kit go to http://members.shaw.ca/megasquirt/MS%20FAQ.htm

Read and follow instructions.

 

Correction should read '50DCOE carb pattern throttle body'.

If you are looking at using it on an existing efi engine (GSL-SE or later), then it's really straightforward. If you are planning an earlier 1st gen, then you need to look after fuel supply, intake, injection and sensor issues, which complicate matters somewhat. A kit of those hardware items would simplify things greatly.

I've installed the MS system on my SA and FC. The FC has been my daily driver with this system for a year. The SA is my summer/project car, and has only recently been completed.

 

is v8kilr makin the kit with all component, and an EFI computer reading to go(no assembeling the board)

or what ? im kinda lost :-(

 

answred my own question.... by reading the first post..... if programming is the only problem then why not let me buy a unit from you and try out some programmin myself (some experience) i plan on getting a project rx-7 soon, just need to find one for under 300.

 

I can easily see the improvements this kit could bring, and the demand for it.

Primary injectors in the lower manifold going to use any certain standard fuel rail?

I would be very interested in just the lower manifold portion, if it'll be available seperately. Envisioning horns from the top of it going directly into a properly sized plenum, with a throttle body up front.

 

The lower DCOE manifold for a 12a that racingbeat makes matches the lower intake of a 13b GSL-SE, but not a s4/s5 intake. Just slightly off. I'm assuming one could drill/tap for injectors, and use the rest of a 13b SE intake.... I had this idea awhile back, but I never could find a SE intake at a decent price. Not sure how a 13b ECU would run on a 12a, but it was mainly for a starting point to covert to FI. Very neat stuff.

 

I can sell you a pre-built and tested megasquirt un-programed for $300.00
I have the Simulator to fully test the units without installing them in the car.

It will come with all software and you can program it with your laptop computer.

I will also be selling the megaview kit as well, this is a plug in display unit that can be used to set the megasquirt variables from insisd ethe cockpit in real time while the car is running and under operation.

I have full permssion from Bruce Bowling of megasquirt to sell the unit seperatly

p.m. me for further details, or questions

 

The fuel rail is custom made and does come with the manifold.

The lower manifold will be sold seperatly on my website once 100% complete, sorry no beta versions.

 

I will also be making a custom setup for the SE once the 12a kit is complete.

Mainly because the stock SE setup sucks almost as bad as the stock 12a setup.

Lets also not forget four staged fuel injectors running a lower duty cycle vs. two huge injectors in the SE, with a ton of other improvements to boot.

 

Just to let you all know, the market rate is $200 for a built and tested MS. There are people out there ready to take your orders.

Bill

 

Well thanks for crapping on my thread, but who the hell is buidling these "tested" for $200 ?

What type of background do they have?

I attended college for 4 years working towards a degree in Electrical Engineering, again can you be assured the individual has any background in electronics?

There are components inside the MS that do heat up, if they are not soldered correctly, or even if the correct type of solder is not used your mega squirt can be rendered useless in less then a year, which brings me to my next argument.

What type of warranty do they offer?
and if there is a warranty how long will it take to get a replacement unit?


Like the saying goes you get what you pay for.

 

I have assembled a number of MS units and also looked into the failure modes that have occurred and in my capacity as a chartered engineer can state that, for a rotary installation using up to 4 mazda low impedance injectors you do not need an engineering degree to assemble it. Bruce Bowling designed it so that ANYONE could build it. The instructions in the manual are pretty specific on the areas where you have to take heatsinking into account.

Those who I know are offering these kits are either fully qualified or I am confident in their workmanship enough to say that if they won't offer a warranty I will. In both cases they have been running one or more cars with MS for over a year without problems.

I think its good that you are assembling a fully tested kit of parts, but MS is all about a community pulling together to improve the system for everyone. From the discovery of the staging functionality within the code to allow easy use of 4 injectors, through the dual table code that allows different size injectors on primary and secondary, Rogers Easytherm so you can use stock temp sensors and Mike Roberts mods to allow you to simulate ported vacuum if you are using a TB that does not have a ported output, ALL of this has been given for free to the community. I can also add launch control SW, flat shift (under beta test) and many other little add ons. As all this is free why should you mark up a built kit by $100 over anyone else because you offer a warranty?

Its a free market and if someone wants to pay your markup instead of buying a spare MS kit then I can't stop them, but I will tell the list that there are other ways that are cheaper.

 

hmmm i think i might wait to get a unit once i can get injectors and the other necessary things to get it going.
