ECU Tuning the 1320 way...........
Hopefully, when you are ready to tune your car, having undertaken a series of modifications, you will have selected the uprated 550cc Bosch injectors – the Bytetronik software allows the accurate scaling of these to ensure safe precise fuel flow into the cylinder head.
The idle on the MINIs can sometimes be very rough when running a performance camshaft, but with the Bytetronik software we can adjust the idle to be as smooth, if not smoother than a standard MINI. This is all achieved by adjusting the scaling, fuel map and idle control. The idle for us is crucial as it shows that time has wisely been spent checking adaptations and trims to obtain a perfect base map.
Being able to log and observe what the ECU is seeing helps us with the tuning as we can monitor knock voltage, knock noise and individual timing. We can then adjust the fueling / timing in each cylinder for reliable safe power.
The Bytetronkik software allows numerous and varied adaptations from sublime to the ridiculous and Thomas’s likes nothing better than show you the intricacies of your own personal map as it evolves.
Once the vehicle’s tune is optimized we go with you on the test drive just so we can then measure the smile on your face!

ByteTronik MINIFlash FA53 Kit
For those who want to do it themselves the guys at ByteTronik have now given you the freedom to do it at your local dyno, this is extremly handy for those who don't like driving too far or live in Europe.
This kit consist of one piece of hardware and one piece of software.
Hardware
As you can see below you receive a MINIport OBD-II device along with a USB cable. The MINIport aslso doubles as a data logger device and can also log AFR (provided you have an Innovate LC1 device fitted).
Software
This is a Bytetronik proprietary software designed specifically for the MINI R53 platform. It’s about 10MB in size and can easily be installed on any Windows Platform (Windows 2000 or newer with a minimum of 512MB of RAM). The FA53 has an easy to use GUI for user to easily navigate through the various levels of tasks and commands, and when connected to the MINIport, it allows users to flash and configure their ECUs.
MINIFlash FA53, is a complete tuning kit that allows end-user to perform the following tasks:
Feature 1: ECU Adjustments. This allows the user to have complete access to the mapping inside the ECU and be able to adjust over 30+ parameters that pertain to Air/Fuel, power delivery and drivability. Once you are satisfied with your new tune, you can save the map and reload it back into the ECU at any given time.
Feature 2: Map Switching. Once the maps are made (typically for 95 Octane, 99 Octane, 100 Octane, Race or E85 fuel), then you can simply switch it back by loading the particular map that best suits the situation. In addition, you might want to clear the Adaptation while you’re at it.
Feature 3: Data Logging. If you want to see how the car is running while you’re driving. Simply disconnect the USB cable from the MINIport device (while leaving it connected to the car’s OBD-II port), and the data-logging feature is now active. Blinking red/green/blue lights indicate that the MINIport is actively logging 30+ parameter at 8 samples-per-second, and all this information is stored on the onboard micro-SD card. To view the logs, simply connect the USB cable to the MINIport device and you will see the data on your laptop (it will show up as a “Removable Storage Drive”).
Feature 4: Read DTCs and clear them. Is your MINI throwing a Check-Engine Light? Well, instead of reaching for the OBD Scanner, why not just turn on your laptop and see what’s causing the code. And once you find out what the code is about, you can always clear it thru the FA53 software.
Feature 5: Clearing Adaptations. Is your car running sluggish lately? Well, check out the data-log and see if there’s anything that looks unusual. What about the “Long Term Fuel Trims”? Is the ECU learning some of your bad habits and over-compensating? If so, simply go to the FA53 GUI and clear the adaptation values. With the MINIflash, you don’t need a BMW Factory tool (GT1 or Autologic) to perform this task… simply select a command in FA53 and turn off the ignition for 5 minutes for permanent changes, then you should be good to go.
