Here's the link to the binary, http://www.rbracing-rsr.com/downloads/K1200rs.000.zip
It's from a K12 flat.

Look for it on this page about halfway down, http://www.rbracing-rsr.com/blackhol...0exhausts.html

With the data from an original EPROM, and the BMW accessory EPROM, or the copies sold by some vendors, a comparison can be made. With that comparison, finding at least the fuel maps would be much easier.

OK, this will get you started. Maybe more tomorrow from work.

Those of us out here in the industry consider that cheating. The fuel tables are easy to spot if you know what you're looking for, and even easier once you've disassembled the code.

And decompiling the code is, what, not cheating?

You're holding that out as a fuel table?

I'm not pulling out my A+ material to settle a tinkling contest on a forum I never visit, sorry...

It's just a table, one of hundreds. No clue what it does, or if it does anything at all. But if I can find and visualize one, I can do the same for the rest. Once I've seen them all, I can find where and how they are accessed by the code. Once I've got that figured out, I can determine which ones do the things I need to tune.

It's the difference between learning an instrument and forming a band and copying CDs.

Oh, from a search on Google Images then.

When can we expect you're going to be not visiting?

Oh Jesus, you are miserable. That table is located at 0xED38 in the binary file you pointed me to.

I will disappear back into my own corners of the interweb soon enough. Hopefully I'll find some BMW bike ECUs to buy and hack up before I go. (hint hint)

Good luck with your little farkle toys.

Thanks, man. I sure appreciate the well wishes.

Last night I decompiled the code on the Motronic EPROM. Certainly not a significant task. I'll post up the file later tonight should anyone want to take a look at it. It's likely you already did this simple step, Matt.

I don't have the software tools to go forward from this point, with any degree of efficiency I mean. There may be some good shareware or open source tools available but I haven't devoted the time to find them.

food fight!

My HP2 runs great with Bobby's Akrapovic and aircleaner......not certain I'd change any part of the injection for FREE! Bruce

Yes, please. I know little about engine management, but I know a good bit about assembly languages. I'd enjoy having a look. Is all the executed code on the EPROM, or is there also some elsewhere in the unit?

The main problem I see in this whole thing is two guys shooting the shit on teh internet instead of toiling away in their garages, getting more horsepower for me and my GS. Snap to it, fellas!

Poolside / JJ have found some neat, and apparently, inexpensive ways to tweak the input to the ECU to improve performance.

They then tweaked the noses of those who actually reprogram the computer. Well, one of the tweakees decided to call him out.

No biggie.

What may happen is that PS/JJ may decide to enter into some negotiations with the Tweakee. Perhaps something better may come of this besides internet wrangling.

Pass the salt.



I'm such a shit.

We did some real world playing yesterday on my 2004 1150 Adventure. 161,782 miles on the clock. A couple gallons of gas in the fatty tank, so it was easier to on-and-off.

Poolside installed the air-side mod first. After I'd run around the hill warming up the bike.

I've had a blackbox of confusion on the bike for a good while now, but idle has never been steady for more than the last 100,000 miles. It was with that one modification. The idle was a bit higher, but still smooth without the usual stumble.

My seat of the pants dyno is pretty lame but even I noticed better get up and go with the second mod in place.

No low speed stumbling, nice smooth throttle response.

50 mph wheelies are new to me on this bike. I believe I am addicted.

Probably need to lay low of a few streets around the hood for a bit.

When these get packaged sign me up gentlemen.
