BMW R1100gs

The R&D

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 - and that stumbly 2800 rpm cruise.....

Sooo.......

There we were.......  Riding, dynoing, riding, emulating, riding, dynoing, pondering, asking questions.....

So....

We made a map, then another, then another - then we rethought.... another map -
Well - we managed to get at least 1 bike running smoothly at 2500 to 3000 rpm cruise. It's pretty interesting - the chronology of tuning events - but it's probably only interesting to me - so I won't bore you -

Best setup is individually tuned - as most of the gs guys/gals have already swapped  inlet tubes, and yadda yadda to try to make the stumble "go away"... But, from what I saw last week, it looks like there are only a few people who actually know what is actually wrong at those low rpms.

As far as chip sales, we will, as we have done for the Aprilia and Ducati chip users, apply the full amount of the retail chip price towards the cost of custom tuning ($775), if that's desired.

 

It took the EC997 Low Inertia Dyno to do the job -

no other dyno has done as well.

None. Period.


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".
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!

.........................

From the tuners with more (successful) m/c Fuel Injection tuning experience than just about any other USA company.....
(we tune Bosch, Denso, Mag-Mar, Suzuki and
pc's (if it's the only option).

A BMW  "chip" that works.
At full throttle, part throttle, closed throttle and every point in between!

These chips 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.

$229.95 (drop-in chip)     and    $775 - (for custom programming)

(~1 week turnaround)
(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 others?
You would need a
4-Gas EGA EC997 Low Inertia Eddy Current Dyno to know.
We developed the FLUX Factor.
Smooth cruise.
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.
Period.

We take trade-ins on competing dyno systems.

Still tuning by luck?

Stop.

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.
