On this engine there are a lot of maps for timing control. I have developed a solution to switch all the maps(84!) in the IgnCtl module. This means you have full control on timing for E85 setups.Another solution to change timing by adding a correction factor from a separate map is being developed. Here’s a video:
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.
Here is a video of it in action:Keep on Reading!
