reburn chip

[obx tsi]

Who can reburn a chip for me that I purchased from someone? I bought it from a guy in canada and the major thing that I want changed is the injector size. It is for 750's and I only have 550's. I also would hope that it is not the full cost of another chip. Thanks for any input.

Why not buy a chip burner and do it yourself? You can get one from Moates for like $80

Nice...

That is great....I figured the chip burners cost a lot of money. Is it hard to burn your own chips? (i have a keydiver 2 map chip...the bigger chip) Is there a place that breaks down how to burn chips for our car (Like chip burning for dummies...). I have no experiance in this but I think it would be somthing I would like to mess with.

Thanks

It's for EPROM ecu's...First Generation DSM EPROM Editing

There are several additional resources available for use DIY chip tuners. You could also check out the yahoo group DSM-ECU which goes over a lot of the more technical aspects.
It also has a lot of resources available to use with TunerProRT, which is a leading logger and editing program that can be used for free. I have done a lot of modifications to my chip; to the point that I don't even need an AFC while using different injectors and 2g MAF.

The blank chips are only about $5, so you can even make multiple chips, use a switcher between different settings, or install an extension for access outside the ECU. There are many options, even an emulator that allows real time changes if you choose to go with the Ostrich 2 EMU.
Moates.net has just about everything you'll need. Keep in mind, they aren't made specifically for DSM's, so the electronic resources on the site are not very good. But that's what DSM-ECU is for.

BTW, Jeff from KeyDiver is the primary contributor to DSM-ECU.

That is a great right up. Do that have one just like it for a 2g?

Umm no sorry I don't... But that gives you a good idea...

These guys are right..Join the yahoo group.. I don't have a link for that..

The 2g DSM has not been decoded the way the 1g has been. As a matter of fact, it's far behind in terms of public availability. The only companies that have invested the time and energy (and money) into decoding the 2g are protecting their investment, as well they should. The 1g was fairly simple in its design and much of the important parts were quickly available to the public after they found what code base they were working from.

With the entrance of the OBDII and the universal application (across all manufacturers), it appears that Mitsubishi was more careful about protecting their programming methods, just as any computer programmer would. In other words, there is no simple system to the 2g platform, as there is for the 1g.

 

[Bud92gsx]

What about the 95 eprom ecu... Wouldn't that be simalar to his 98? And you can burn chips for it too right?

 

[obx tsi]

I got up with jeff. I was looking for other routes but I would much rather him do it.

 

[architechnik]

Again, the 95 EPROM has not been completely decompiled and made publicly available the way the 1g has been. And not all the versions of the 1g have actually been done, it's just that they are all so similar that the one version can be extrapolated or directly overwritten other versions of the 1g.

That's why it really is better if you have someone who has a business, such as KeyDiver, who has put in the time to make the best of all the modifications possible.

Even with the decoding done to the 1g allows for variations, and there are several tricks that Jeff keeps up his sleeve and hasn't let out. We occasionally ask him and it's up to him whether he thinks we are worthy, but we try to respect his secrets and don't ask other owners of his chips.

With this in mind, you can burn chips, copy chips, but with the 2g it's hard to edit chips beyond some very basic alterations without those trade secrets.

 

[mike96]

do some web surfing for "2G ecu tuning" you can find some things like this... Ceddy's Lair also there is a Yahoo news group that can help with 2G chip tuning.

 

[Bud92gsx]

What on the 2g ecu can be munipulated so far?

 

[steve]

The 1g was fairly simple in its design and much of the important parts were quickly available to the public after they found what code base they were working from.

If you consider that there was nothing other than TMO for years and it took almost a year to discover the basics by reversing engineering and disassembling the code by hand on the yahoo list. It didn't seem that simple or quick at the time.

By no means do I discount the work that others have done, only that it seems that the 1g was done in less time than the 2g has taken.

Steve, could you pinpoint when a comprehensive understanding was presented to the online community? Which came first, the release/decode efforts of the public or the closing of efforts at TMO or were these not entirely related?

 

[steve]

I don't understand your question.

TMO had been closed/out of business for several years before the Yahoo list was started in Feb 2002.
Tom and Dave at ECMTuning had released DSMLink V1 in January 2002 on the 2G after about 5 years of development.

Jeff O joined the list about Dec 2002 and brought with him the work he had been doing on his own, that's when the project started gaining traction. I joined in Feb of 2003 and we still didn't know what the full instruction set was, the CPU register set, or the layout of variables in RAM. People knew that the CPU was a member of the 6800 family and what a handful of variables were for. There were a bunch of OG people chipping away a pieces, a map here, a subroutine there but we were scratching the surface.

Around the end of 2003 and early 2004 pieces started falling into place. In Dec 2003, the first versions of the editing FAQ posted above was published based largely on the information Jeff O had shared. By the late 2004 enough was known that Evilscribe and TunerPro .ecu files started showing up.

It wasn't until Feb of 2006 that a what might be considered a "final" source listing was posted. There are still more to be learned but most people now just want the answers or the tunerpro .xdf files. This is why there isn't much for the 2G, there is a shortage of people willing to do actual work.

You hit the nail right on the head there Steve.

Architechnik, the 2G(1995) code isn't more complex or protected than the 1G, its just a revision with OBD2 and some emissions added. They are exactly the same at a lot of spots.

There is more done on the 1Gs because when DSMLink first came out it was only for the 2Gs, and the 1G guys had no alternative.

Go with jeff at dsmchips.com ...good servive and communication and a good price $20 plus shipping.

 

[obx tsi]

Overall though he has been very helpfull and replied to all my emails.

 

[steve]

You can't go wrong with Jeff's work.

 

[obx tsi]

At least I am going to him rather than a guy who says he can burn one for 10 dollars. How good would that chip be? I could have just got bigger injectors and ran this chip but I thought it would be cheaper just to change it.
