I am from old school and been out of it for 30 years.
So I have decided to learn on my ranoul master 2007 2.5 100cdi
It no power revs to 3000 no load but under load 2200 max and drops speed max 65mph to 50 mph even on 5% clime
I got me ELM327 cable and it came with some softer ware and bought some PCLink G1 to G4 , Scanmaster ,Tunepro Auto scan , magatunex.
I can only connect to ecu with autoscan and scantaster - but I cant reed long and short trims, boost ,
Injectors, open and closed loop - non of the other software will connect
Any help will be appreciated
