thanks joecar for the info , just have a few questions , when installing the latest version of V7 i guess efilive will override the old version and in V8 what is the procedure to flash the V2 with V8 firmware and if i understand correctly V7 will remain the same for logging and editing and flashing , i will still be able to log and flash using my laptop and V8 will log using the V2 (bbl) , will it also be able to flash in a tune to my pcm without the use of my labtop and if so will it hold more than one tune so i can flip from one to another and why doesnt one version do all this , thank you joecar
