A lot of tuners work hard on the dyno to make tunes, only to be copied by rivals. I have come up with a solution to protect the maps by scrambling them. This means that maps are protected from being copied in boot and OBD mode read. Only the tuner who has my tool(unique for each tuner) will be able to descramble the file.Keep on Reading!
A tuner contacted me to make a special version of map switching. Basically they needed a way to adjust KRKATE for varying alcohol content. Timing maps are also switched depending on the alcohol percentage selected in the cruise control speed display. Speed of 98km/hr in cruise control display corresponds to 98 Octane mode. 85 corresponds to E85. And so on.
Jan of 2019, I was contacted by a offroad racing team. These guys had been using old mechanical pump Mahindra engines in their builds. They were bothered by how heavy these engines were, produced very little power and had a peak RPM of 2800.
I suggested they use an ALH TDi engine from Skoda Octavia. It met all their requirements as it’s significantly lighter(150kgs! lighter), has a higher RPM limit(5000) and can be tuned/upgraded to produce more than 200HP.Keep on Reading!
A lot of tuners contacted us for a solution to switch between maps on the newer generation MED17 ECUs. After a few weeks of rigorous testing we have been able to come up with a robust solution. Here is a video of it in action on an VW Golf MED17.5:
Contact us for a quote and we would be happy to design a solution suiting your requirements.
So for years tuners have tried various different techniques to have multiple tunes in one ECU. There are several advantages to this:
1. Multiple tunes with different output power levels
2. One tune can be tuned so that engine won’t start: sort of like an added level of security as the driver needs to switch into the tune which will start the engine
3. Different fuels need different ignition parameters such as ignition timing and duration to name a couple.
The present method to achieve this was with methods that involved opening the ECU and changing the hardware(flash memory with double the size to have 2 tunes as an example). In this post I am going to write about my journey to achieve a software based solution on the Bosch EDC15 ECUs.
