UltiMap Eproms for BMW Models
BMW has used a number of Motronic ECUs since the inception of it's injected models. EPROMs designed for one type are not interchangeable with others. This may include several versions of a single motorcycle model (for example R1100S)
You should identify which ECU you have, by checking the Bosch AND BMW part numbers on the ECU.(see left). If necessary you should also check the EPROM chip serial number by opening the case.
This approach is less confusing than the use of the model year so we have not shown model year in the table.
R1100S ECUs are grouped as EARLY or LATE. All Early R1100S types use the UM82x series, all Late R1100S type use the UM85x series of chips.
We now have Eprom chips to suit Boxer Performance products with the R1100S model. These include the Boxer Performance InDuct and the Boxer Performance 9 degree Cam Sprocket. Both of these products work very well, and together with the right UltiMap chip are a formidable combination.

What are UltiMap EPROMS?
We've constantly updated and revised our eprom products, and now we have UltiMap eproms for Ducati, Guzzi, Aprilia, BMW, and Laverda.
These chips now have separate fuel maps for each cylinder, vastly improving mid-range smoothness and response, while still delivering the best available top-end from a given engine/exhaust combination.
We supply a chip puller and instructions with every chip, all in a specially designed crush-proof package which will mail-order safely.
Why are UltiMap Eproms necessary?
UltiMap eproms are specifically re-mapped to suit each particular bike with a particular exhaust type. Your Ducati 916 may have Termignoni, Skorpion, or Arrow mufflers fitted, but the performance is no better than the standard system. The fuel maps are wrong.
Manufacturer's goals aren't the same as the buyer's goals. Their EPROMs are compromised to meet stringent noise and emissions standards, have good fuel economy, and accomodate variations in engine tune and exhaust systems safely. In other words, they are DE-TUNED ! Most owners are interested in two things: Power and Acceleration. These are not really primary goals of the manufacturer, and their EPROMs are made accordingly.
Also, the factories do not allow for mixture variations between the two cylinders of their engines, which means that one is always richer than the other. Typically in the mid-range this produces very rough running.
Take a look at the Exhaust Lambda chart below: you can see the mixture for each cylinder as the throttle is opened, at a midrange RPM of 7000. The rear cylinder exhaust lambda is dangerously lean, while the front cylinder is way too rich. This is a factory chip in a standard factory bike.
How are UltiMap EPROMs different?
It's the Ultimate Map, see ! Our Eproms are individually mapped for each cylinder. We use brake dynos to test each point in the operating range, and adjust each cylinder separately for ideal combustion.
This ideal is dependant on both RPM and throttle position, because the mixture must vary to produce the best result; either cruise, pickup, or top-end power.
Our chips produce vastly superior mid-range throttle response and smoothness, and allow the engine to produce maximum top-end power as well - this is a complicated process which few companies are capable of. We also raise the rev-limiter by 500 - 800 RPM to give you more room to move. Take a look at the typical power benefit on the dyno chart below !
Customer Satisfaction
Here are some unsolicited emails from our customers...
"Duane, I ordered a 061p chip from event technology here in the US per
your recommendation for high altitude...
I installed the chip and I can't believe how much of a difference it
made. I love it! The off idle response is incredible and so is the
midrange power. I let a fellow 916 rider try my bike and I didn't tell
him about your chip to see if he could tell the difference. He could
tell immediately that something was different, he also couldn't believe
a chip could make that much difference.
I am totally satisfied with your chip...
Thanks,

"Dear Duane, You're a bloody genius! The chip you sold me is the
absolute goods. I now have a smooth running 748SP with no apparent
holes in the power curve and less vibrations throughout the rev range.
For some reason the Termi's make a little less noise but it's a small
price to pay. I can't wait to get the cams dialled in to see how much
of an improvement your chip really does make.

Can my dealer adjust them to suit my bike?
All of our UltiMap eproms are compatible with the Fuel Injected Motorcycles Mapping System, which means your dealer can adjust the eproms using MegaZone technology to suit your needs. Using our Hand Terminal they can adjust Fuel, Spark, sensor corrections, and much more in a simple and quick operation. Ask your dealer for information.

Refer to photo on left - the notch on the UltiMap chip should be placed at the same end as the notch on the BMW original chip. Make sure you mount the entire UltiMap, complete with green socket (pictured).
