smkn951

thanks everyone
another question...
will it just plug into the wiring harness where the dme/klr is?
or a harness will be needed to be fabricated?
would a pda work or a laptop is neccesary?
what about tuning?
are there presets for changing driving styles?

All of these questions can be answered at http://www.megasquirt.info/.

Click on the FAQ.

To answer those questions, yes it is laptop controllable. You must have a laptop. It is tuneable on the fly, just like AEM, TEC3 or MOTEC. It has the same basic features of any of those setups.

No burners needed to tune. Plug the serial cable into the laptop, and go to town. Theres multiple choices for software to tune it, even stuff that will run on a Palm Pilot. The menu options will change based on the firmware for the MegaSquirt, but other than that its the same.

To load different firmware, you just change a jumper on the PCB I think. Again, no burner hardware/etc.

It has to be hacked, unless you want to make a harness.

Laptop OR PDA, but a PDA will only change a few basic settings.

Theres support for dual maps, so a low boost/economy/crappy gas map, and one for power.

hmmm.....maybe SDS isnt the way to go for the turbo NA.

but the 500 rpm thing isnt clicking with me. I know it averages it out. but....idk.

Interpolation is a good thing

Campeck

the SDS interpolates from 250- rpm increments though! lol.
i need to think.

944 + MegaSquirt discussion forum: http://www.darklightning.com/motroni...forum.php?f=22

I'm hoping that'll help all of us work together towards the mutual goal of a MegaSquirt'ed 944.

I didnt see anything on their site about interpolation and if their systems do it or not.

I think I regged a while ago, ill post in that part of the forum at some point soon

I am in. My engine is going out for a rebuild. I am very interested in converting to a full stand alone EMS by MegaSquirt. Lets keep this board active. I believe once we can successfully tune a 951 using a megasquirt EMS, it will become very very popular. My 951 is an open guinea pig right now for anyone interested in using it to develop a proper D.I.Y. SA EMS.

Alex, I have one MS powered 951 being built right now. I don't have the $ to do it any other way (not that I'd prefer another way even if I did).

We're working on hashing out a a suitable trigger signal to the versatile MS (nS-Extra) wheel decoder. Dark just proposed a "Divide by N" counter on the Motronic board that could theoretically divide the 132 tooth flywheel signal into 44 (132 / 3). Then the stock ref sensor gives us the "missing tooth" that we'd need, so effectively a 44-1 signal with about $5-10 in electronics added to the stock sensors.

If we can get that to work, then the 944 world should rejoice!

This is a very interesting idea. How is the boost going to be controlled? Does a new circuit have to be created? Does the MAP give a suitable signal for operating the stock boost gauge?

WoW! You guys sure know your stuff. I have joined a couple forums regarding this topic (motroniccode.com & msefi.com) to stay informed. Let us newbies know if we can help. Keep up the good work.

That sounds quite promising as well.

With the V3 board, it should be easy to build the divide by N counter on the proto area, and just jumper it in between the CPU and the signal processing stuff.
