I've found an FI computer that's pretty cheap ($400) and I'd like to swap it into my 94 RS so I can remap for better economy(yea, right, like I care) and more oomph.

Feasible?

Implications?

bmwmick to the white courtesy phone, please.

Just for the record, I 'have' fixed a couple of Motronics by disassembling them and soldering new components in. I have never tried to disassemble the programming. Do you have some software tools that will do that? You have a ROM burner?

I'm talking about replacing it altogether with a "Megasquirt" computer.

I was talking today with a guy who is going to custom turbo a K100RS4V and plans to use their new one.

If I could get one of those working on my K1100RS then I could remap with PC software.

Here's some info on the Megasquirt:

It'll probably make more sense to you than it does to me.

Drake,
I'm sort familiar with the "Megasquirt" but what is your goal? Better mileage? hot rod? Personally, I think you are wasting your time and money. Crying or Very sad

These things run great as is. I'm running about 3 degrees more timing advance and just a little richer than stock and I still see 45mpg if I keep it under 80mph (which is hard to do in AZ) Smile

More horsiepower is my goal. I'm sure K1100s were detuned quite a bit before they left the factory. Heck a K100RS4V puts out 100hp and we've got 100 more cc's so I fgure there's at least 10 more hp hiding in there. And with a Staintune installed and no cat probably more left untapped. It'd also be nice to up the redline by 500 or 1000rpm for REALLY ripping through 1st and 2nd.

I figure if I could get another 10 more hp or more for less than $500 it'd be worth it. To be honest I probably wouldn't use is that much for fear of being hard on splines and the driveshaft but it would be nice to have.

Or maybe I should just get a Busa. Laughing

This guy installed a megasquirt on a K75 turbo.

Plus one of my coworkers uses a megasquirt on his Jagrolet (Chevy V8 motor in an XJ-6) He's been pleased with it and claims its easy to program, but then he's an embedded system programmmer so it should be easy for him..........

Looked at MegaSquirt for my old 4-wheeler BMW, mainly as it was running Motronic with the "problem" moving-vane airflow meter... The main advantage with an add-on was to allow for more "maps", either for ignition advance and/or injection durtion, but usually keyed to extra events, like turbo boost pressure, or transmission state... With an "open" system like MS, there is more ROM and RAM area, and any changes don't leave you fighting the anti-hack checksums Bosch build into the Motoronic.

I guess tuning-wise, the opportunity is to mirco-tune to smaller steps in the maps (say per 100rpm, not say 500rpm) and to add tweaks like more pseudo accelerator pump action. I guess with something like the K with a binary gear indicator, you could also tweak for different maps for different gears, and use the clutch interlock switch too as a retard flag to spare the clutch - the big call is is it worth the effort? Also - if the only benefit is to refine the curves, are the original sensors accurate enough? Biggest worry for me would probably be the TPS, since it's a predicitve input, it doesn't measure an absolute engine parameter (like engine vacuum, as per a MAP sensor).

God luck, but I dunno if you'll acheive anything much!

Yes, much study is involved and this would be a winter project. My thoughts are to use a mass air flow sensor from a 2 valve K and hook up the the O2 sensor to the Megasquirt.

My concerns relate to the idiot lights and other stuff controlled by the Moronic.

Is it safe to assume that the Moronic and ABS brains are more or less independent?

They are smooooth ...

Yes, it is still the fastest production motorcycle (The Hyabusa is a Japanese hunting falcon, which kills Blackbirds Very Happy

)
With a timing retard eliminator and PowerCommander, they can reach a real 200mph.

And yet, it is one of the most neutral, precise handling bikes I have ever ridden.
Effortless power and superb brakes - It is the best $6K you could spend on a motorcycle.

Fit some helibars, and you can even go touring Wink

Im gonna make Johnny buy me one when he wins the lottery.

I've often considered poping by the dealer to take a Busa for a test spin. Sounds like it might be worht a few minutes of my time - but I'm scared I'll like it too much.

I was looking at Megasquirt for my turbo project. I also found a company called Halteck that was used my Luftmiester back in the late 80s. They cost a little more then the mega but I understand they are easyer to program. Both will work with a Hall sensor and if you dont have a o2 sensor you will need to instal one. My K100 did not have one but there is one in the luftmiester exhaust. If you can have your friend get in touch with me about his turbo project I could use the help and any additional info he might have.
