I just want to learn how can i modify my car and download a softeare like apr , revo ?
You can learn to tune it, but buying software/tunes like APR etc, you have to contact the re-sellers, this is a DIY forum - look for Tunerpro free xdf files to help free DIY tuningWich one is perfect for me ?
Each ecu is different, read into what others use with that ecuAnd how can i oppen stage one and up to ather stages ?
You pay for staged tunes or learn it yourself on here then you can modify it as you will!Can anyone help me up to tune my car ?
Yes lot's, either learn it yourself on here and people will try to help or you're looking for a quick stage tune so expect to pay people for work really!I just see everyone doing mpps
Works well for many, different tools have different protocols so work different with different ecu's, look into the differences on threads on here!And read me7.5 what is that exactly and ehat is that doing ?
ME systems developed from early M1-5/6 systems which all vary, look at the differences in the "Motronic evolution" thread I did linked below for changes. This is mainly an ME7 forum for later ecu's over AGU etc but some info about on these early ones!Is it like a software or what ?
As above, software/ecu interaction differs - look into what people post for an understanding of ecu/flashing soft/hardware differences, like I say, basic changes to the systems detailed here; http://nefariousmotorsports.com/forum/index.php?topic=10419.0title=
