I know there are a few threads kicking about with stuff on the rs tuner but none have a fix to my problem. I have unlocked my rs tuner connected it to the ecu entered the VIN code etc. Now when I go to read ECU it comes up saying could not obtain security access to ECU make sure the engine is turned off (ignition on) and engine is below 50 degrees celsius. My car is stone cold and I have the ignition on when I'm trying to read the ECU so I'm a bit stumped now :S anybody experienced this before?
