Switch upto 9 map sets of unlimited number of maps(flash storage is the only limit!)
Just finished writing the backbone of my flashtool last week. Can flash any MEDC17(presently only UDS based). Here’s a snippet of a EDC17C46 being flashed on bench:
It’s not just an FRF flash. Any modified file can be flashed(code and data area). An exploit in the bootloader is leveraged to allow RSA check(TPROT) to be bypassed and allow unsigned code to execute.
Presently using Tactrix Openport 2.0(J2534) as an interface and Arduino Due for logging CAN traffic.
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!
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:
With this ECU, I have implemented mapswitch on all EDC15 ECUs released in the market by Bosch! This version has 4 datablocks switched by:
1. Press and hold Gear lever +
2. Press Cruise control cancel once to view selected datablock
3. Press cruise control cancel again to switch datablocks
4. Release Gear lever + when done.

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!
I had to program a legacy EEPROM on a Mercedes EDC15 ECU. I had a choice: to buy a reliable tool to read/write the E2P(3SP08/95SP08) or make my own by reading the datasheet. I chose the 2nd option.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!
So we’d originally done this project 8 years ago, on our older Skoda Octavia.
It was time to do it on the newer one now.
Too analog, gotta add some electronics to this.Keep on Reading!
