FastECU

Open source software to work on and modify Subaru ECUs and TCUs!

Software contains some modified source code and kernels from nisprog by fenugrec: https://github.com/fenugrec

And from forked nisprog/npkernel project by rimwall (modified for Subaru): https://github.com/rimwall

Huge thanks to following:

• rimwall
• SergArb
• alesv
• jimihimisimi

Also big thanks to:

• fenugrec, whos kernel development with rimwall for Renesas SH-processors made this project to start at the first place.

Without all mentioned efforts this project would not be succeeded so far!
