Audi had quoted upwards of 6lac(8000$) to replace the gearbox. The first thing we did after purchasing it was to get the mechatronic unit out and fully disassembled: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.
