-Hello from the US. I am learning what I can with tuning edc15c6 on mercedes. Most of my experience is with hptuners and efi live on cummins. Looking forward to learning on software that isn't so restrictive. Even if you have the access to user defined parameters in hpt and efi they are still limited on what you can actually do. So if you need help with those, I would be glad to. Have a wonderful day!
