R1100RT- (inc P bikes)
BNW's and most other bikes are different, bike to bike (as far as the good tuner is concerned).
We tried dealing with BMW riders for quite some time and they range from riders with everything set as per factory spec, TPS, valve clearance, idle air bypasses to riders with zero mechanical aptitude and poor social skills - and the majority who were willing to accept rather slightly flawed low speed running - as they knew that they would have to do additional work to maybe make it maybe optimal. I hated that.
Even IF TPS and valve clearance and air bypasses were set exactly the same - experienced tuners know that each bike is potentially different, as far as optimal tuning as concerned.
So - in order to provide the means to making a happy
bike and rider, BMW tuning will be done custom, with no drop-in chips available.

The first question was - Exactly
what what WAS the biggest issue with the Boxers???
Well, it seems that the on/off throttle operation was, errr, jerky?
And the bike wasn't particularly, umm, quick or responsive.
There we were....... Riding, dynoing, riding, emulating, riding, dynoing, pondering, asking questions.....
We tested, groomed, brainstormed, massaged the innumerable maps hidden in the chip till we were almost happy - More power, nicer throttle action... We thought that we could maybe do even better... Well, we rode, dynoed, rode, emulated, rode, pondered, asked more questions.
Groomed the maps so that the power delivery rate matched what a person riding a bike would perceive as "nice, linear, responsive and sprightly".
Made little tiny incremental changes. Made more tiny incremental changes. We made changes so small that we couldn't tell that we had changed anything.
We were at a loss on how to make the mapping any better than we had - we were stuck. Then .....
We reinstalled the original, BMW maps.
OH MY - OH MY!!!
The r11rt 100901403 map that we had ended up with was
It took the EC997 Low Inertia Dyno to do the job -
no other dyno has done as well.
The BMW R1100RT is a lightweight, full dress twin that has the unique ability to project a personality.
Delivering incredible handling, light weight and strong, torquey engine output - Light and a "hoot" to ride!
The FI mapping, is, well, OK.
Cruise smoothness is usually OK, perhaps a bit "surgey" - snap engine response is pretty good and topend / full throttle power is all right.
EPROM/Chip Performance benefits
So - what is there to gain from replacing the stock "chip" or "eprom"?
2nd gear / cruise operation could be "silky", engine snap response could be very lively and full throttle power at high rpm could be improved.
Just like we did this year with the Aprilia Milles, using the EC997 4-Gas EGA Low-inertia dyno systems, (less common and much more finely developed than any current dj dynos) we have developed a set of fuel maps, air temp correction maps, coolant temp correction maps, cylinder compensation maps, offset maps and acceleration maps that optimize engine performance beyond any other current retail maps or power commanders of any configuration.
Can you do that with any silly
"Auto Tuned" procedure? Absolutely "Not". At least not
It takes a human being to adjust maps to "feel" best and to respond with at a rate that feels "right".
A computer CAN'T do that. It can only go by inhuman numbers.
Inhuman tuning? Go slower.
Lovingly hand crafted maps? Go quicker!
"chip" that works.
At full throttle, part throttle, closed throttle and every point in between!
These customchips deliver smooth running
at cruise, full throttle AND at part throttle - even at 2k and 7k rpm!
Smooth. Silk. More power, everywhere.
That's about it. Simple.\

(BTW - a power commander will never reach the potential performance of a native chip as stated by dj dyno owner)
How did WE do it - and not the
You would need a 4-Gas EGA EC997 Low Inertia Eddy Current Dyno to know.
We developed the FLUX Factor.
We designed the dyne system around it.
We use the same dyne system that we sell.
No other dyno will provide
the dyno information required to improve the BMW R1100rt as much as we have.
We take trade-ins on competing dyno systems.
Still tuning by luck?
What does it take to design a map for a
fuel injection system? A few things.
An exquisite low inertia dyno,
the 4-Gas EC997, that can measure
part throttle engine smoothness (State of the Art dyno feature - and
not a dj feature)
Lot's of test rides....... (Gee - that's a "bummer"! :-))

– Since 1865
Specializing in Handmade Brie & Camembert
|Marin French Cheese Co., also known as The Cheese Factory and Rouge et Noir is not just the oldest cheese manufacturer in the country, but a vacationers and day trippers destination as well as a unique part of American History. Located north of San Francisco, east of Napa County, west of Pt. Reyes and Olema and south of Sonoma County, Marin French has produced hand crafted Artisan soft ripened cheese since 1865. Rouge et Noir cheeses are similar to French and European varieties but reflect the characteristics of Northern California, producing it's own regional style.|
|The extension of the laboratory
for engines of the Swiss Federal Institute of Technology was completed
in about 1935. Its architect was Rudolf Otto Salvisberg (1882-1940).
He had a successful career in Berlin but returned to Switzerland after
the advent of the Nazis. His architectural style was somewhat similar
to that of Erich Mendelsohn. The staircase of the laboratory is in normal
use but well preserved.
Edited to the tunes of Chemical Residue by Herbie Hancock.
Maybe in next rewrite, he'll fix the ignition timing and dyno chapters...
Otherwise great book with great starting ideas.
