Using the latest on-board 16 bit processor with 40 MIPS (Million Instructions Per Second) processing power, the improvement of processing speed is phenomenal!

If you compare the older 8 bit platform to the new 16 bit, there are already huge speed gains, as the 16 bit code is almost half the size of the 8 bit code. By adding the code improvement, LetRipp Software is about 6x faster than any other current Perfect Power product, in completing a task. Because of this new technology, we have speed and memory to spare, and so we have included more features, which were obviously impossible on the old platform.

All NEW products using the LetRipp Technology, ensure that the response time in the software, is quicker to the change of the engine and feature a much higher resolution for precise tuning. In addition to the high speed processors, the LetRipp Technology has larger memory for more tuning and calibration maps. This includes bigger tune maps, 16x24 cells, more side maps with 24 cells each, on-board help, on-board default map and a larger history map, to mention a few.



Most NEW products will have USB 2.0 communication running at 1.2 Mbaud, but as we endeavor to provide product solutions for all types of markets, Perfect Power will also release NEW products with FASTER Serial (RS232) communication running at 112Kbaud. Current Perfect Power products which have Serial (RS232) Communication, run at a standard 19.2Kbaud. Using Serial Communication will ensure that prices remain cost competitive. Those who have modern USB only laptops will benefit from the USB 2.0 connection with the vast speed improvements.



The LetRipp Windows Tuning Software is "state of the art" and boasts the very latest design, with the ability to cater for every scenario in the tuning world. It has a dynamic screen layout with a complete graphical interface.

Screens can be switched OFF, or ON, or HIDDEN, or MOVED AROUND to make tuning a walk in the park. The LetRipp Software caters for different screen sizes, including dual screens, but it is best viewed at 1024 x 768 pixels or higher.

When using the LetRipp Software, it will use the maximum screen size available on your computer and resize itself accordingly. If you have a dual monitor computer system, you will reap the rewards. Every tuning screen can be moved around, and placed in a position that best suits your visual needs. Select to view your incoming data with a LARGE display or a GRAPHICAL display and the LetRipp Software provides you with live, to the second, real-time information.

To top all of this, your entire screen layout settings are remembered until the next time you start the LetRipp Tuning Software again!



The tuning maps have increased from 256 (8x16) load sites to 384 (16x24). With larger maps and increased resolution, the NEW products deliver a noticeably smoother ride on the road, as well as more power and better fuel consumption.



Online HELP is provided on every item on the screen by simply right-clicking on the item. This enables the tuner to get specific detailed help for that specific item and how to use it - immediately! This is a great feature as it saves you from needing to refer to the manual at critical moments.



The LetRipp Software has a built-in fault detection where it will indicate the fault of a particular item in red. Moving your mouse over this red item will show a fault description, informing you of the possible cause. Faults experienced from the engine's sensors or calibrations are shown in REAL time.



The LetRipp Software includes many shortcut keys using the keyboard, to aid in tuning without the use of a mouse. This ensures that you have easy access to important functions at all times.



Quick tuning aids include column, row and block set on the Tuning Maps.
A fantastic feature is the "Blending Function". Using the Blending Function will enter values on the main tuning maps, by just entering four values in each corner of the map. This means the program will automatically calculate the values into the map for you and this will ensure rapid results to achieve the desired maps without tuning every load point.

All tuning changes have an instant effect and are made immediately permanent.



All NEW products always attempt to go online and provide real time, high speed communication for the tuner. This makes connection with the unit much simpler and faster.



The LetRipp Software is able to or record all real time input channels in such a way that real time play back will be possible at your office desk - as if you were on the road! The amount of space for logging the data is only limited by the available space on your computer's hard drive - the bigger your hard drive the more you will be able to log. All NEW products will record the maximum experienced values of critical inputs.
Without ta doubt the NEW generation Perfect Power products will be extremely powerful and will enable YOU - the tuner, to get the absolute best performance out of your engine.
