ECU TCU Binary Map Tool V5

What does this workbook do?

General Overview. More videos available on Channel

It is intended to make modifying vehicle ECU's and TCU's easier. V4 now with more advanced graphing.

I use it to load my ECU and TCU binary files directly into Excel. Automatically extract the maps. Modify the maps using all the power of Excel. Then export the modified file as binary file ready for checksum and reloading into the vehicle. No other Hex editors. All done from within the Workbook.

Free for personal use, but if you are willing to show your support by purchasing it for whatever you think it is worth, then that would be greatly appreciated. Donations are always welcome.

If you are a business, or using it to make money, then I hope you are fair and purchase it, or even set up a monthly donation.

I am not a professional. I have fixed any errors I found. It was built using Excel 2013. Example file is 2004 Jeep Grand Cherokee with partial ECU maps only.
