Hi just joined the group,
Hope not to annoy to many people

Im new to the whole tuning side of things as i build engines but then pay someone else to do the mapping,
So i have been looking around but cant find anything about, so the question is,
Is there any free software to edit/tune the MED9.1 ecu and to data log it?

This is for my own car (audi rs4 b7) just want to be able to have ago first before spending lots of money of software,

I have the tools for reading/writing the ecu. At the moment i use genuine VCDS for logging but sometimes its not the best. 

Thanks
Luke
