All about this site and MMCd
|
Let's get a few points out of the way ...
What this site isnt:
This is not an attempt to steal credit away from Dmitry Yurtaev (the original MMCd author).
This is not an attempt to sell more Scanmasters (created by Bob Bailey) or any other 3rd party hardware.
What this site is:
Consider this an unofficial 'fork' of MMCd from the Sourceforge and/or it's original non-Sourceforge site. For more information on why I created this site, please see the FAQ.
This is an attempt to expand the functionality of MMCd beyond its original uses (be it for 3rd party hardware or another vehicle platform altogether).
With all of that out of the way, let's talk about MMCd:
For those of you don't already know, your 1G DSM, Galant VR-4, 1990-93 3S and many other OBDI Mitsubishis are equiped with an ALDL diagnostic port. As far as I know all of these ports (no matter what the platform) are located next/attached to the under-dash fuse panel.
That being said, for years there have been commercially available software to retrieve the data that is available from the ECU (however most of those software has been usually more geared towards the 1G DSM's).
In early 2003 Dmitry Yurtaev make his first publically available release of MMCd. This was in response to the now long defunct "DSM Open Source Datalogger Project".
In July 2004 a Sourceforge project was started for MMCd.
Please see the FAQ for more information.
If you think of something you'd like added or expanded upon, please email me using the link on the top-right of your browser! I try to be as non-political as possible, but this is my website, my webserver and my bandwidth... so if you don't like something I have to say: get lost.
Lets get the boring non-tech talk out of the way:
Q.) Why did you start this unofficial MMCd site?
A.) With all due respect to Dmitry Yurtaev, I tried to contact him via e-Mail multiple times in 2003 and 2004 using all known e-Mail addresses for him. I never recieved a response due to spam filtration, lack of reading those e-Mail accounts anymore or perhaps general lack of interest to respond. In the middle of 2004 I discovered Clinton Battersby, aka "cbatters" on the 3Si.org forums, was more-or-less working on an offshoot of MMCd. He had made some neat changes, and had some pretty cool ideas for the direction of MMCd, however it become very obvious he shifted his interest to selling a 3rd party piece of hardware. At the writing of this FAQ (12/24/2004) its unknown to me if this 3rd party device has hit the market yet. That being said, he stopped publically posting source code updates to his offshoot pretty quickly. The last known source code update I have of his is v1.6F. Now this is where it gets confusing, the last publically released official MMCd is still 1.5D.

Q.) Are you ragging on Dmitry Yurtaev?
A.) NO! If I was able to travel to Russia to shake his hand, I would. Thank you very much for giving the OBDI Mitsubishi community something we all needed... including the source!

Q.) Are you ragging on Clinton Battersby?
A.) NO!
Ahh, now time for tech-talk! A lot of this is/was covered on the official MMCd site, but I'll make sure its here as well:
Q.) What do I need, hardware wise, to use MMCd?
A.) A few things are needed:
---
Q.) Am I required to have a Scanmaster or the like to use this MMCd?
A.) NO! I have only added enchancments to MMCd so that I may use my Scanmaster more effectivly. The original functionality *is* retained. This should remain paramount to anybody who wishes to contribute to this fork of MMCd. I refuse to have some super proprietary datalogger project.

Q.) What source code is this offshoot based on?
A.) Short answer: Clinton Battersby's 1.6F. Here is his list of changes since Dmitry's last 1.5D release:
Please see the downloads section for all code updates post 1.6F
---
Q.)How do I log past 1606Hz on my MAF?
A.)Well, first and foremost you need an EPROM ECU that is socketed, then you must modify a ROM image. This exaple assumes you're using an E931 ROM image and that its 32kb in size. If its 16kb, just -4000 from my example hex values. Please do not email me or the DSM-ECU list asking how to modify other ROM's for 3200Hz logging. They and I only focus on the E931 ROM image, which will work in all 89-94 DSM/GVR-4 ECU's.
