As the U59 ECU has developed we have introduced new high-level tweaking equipment for realtime tuning. This includes a CAN-line realtime software package and a 'Slew Box' or Pot Box which allows instant adjustment of Base fuel, rear cylinder fuel, injector phase, spark advance, and spark dwell. These parameters are shown on screen and can be 'grabbed' using the slew box and adjusted. The base file is loaded into the software and shows the throttle and rpm breaks points in sliding windows, so that the load points can be maintained during adjustments. Two channels of linearised Lambda are also shown onscreen along with pre-defined lambda (air-fuel) targets for each specific breakpoint in the map. Once parameters are optimised the Store button updates the relevant maps and allows file downloads of the stored information later.
We have started testing on 999S and R models and will finalise these maps soon.
U59 Features
With the standard airbox our U59 ECU delivered an extra 7 HP at 7400 RPM, and from 3 to 6 HP from 4000 to 10,600 RPM !
With the Airbox lid removed our U59 ECU delivered an extra 11HP at 7400 RPM, and from 6 to 10 HP from 5000 to 10000 RPM.
This is not to mention the extra 600 revs available at the top (fully programmable rev limit).

The maps themselves are independant of the download access code, so the dealer can access the latest maps without needing to re-stock the product, which is the case for our UltiMap Eproms.
So far, we have the following maps:
You can also change the Rev Limiter or reset it to stock. The files are saved independantly of our Ultimap Flashload files and may be securely Flashloaded in to 1.5M ECUs without others gaining access to your tuning secrets.
Both our Megazones and our UltiMaps are adjustable with the same equipment, and to the same extent, but the UltiMaps are better because the base maps are better. Approximate retail price world wide is USD 180.00 or equivalent.
We are undertaking testing of various LSU4 systems to establish which we can use and recommend to our customers.
