I have a mk2 and a mk2a. I run version 1.02 on my mk2 cause I dont have a tuner and I paid 1600 dollars for it. I am afraid to put beta software on my mk2. I put the beta software on my mk2a. It locks up all the time but I dont care cause I paid 500 for it. I notice that my mk2 runs a lot hotter then the mk2a. The mk2a can run all night and be cool in the morning. The mk2 I have runs all night and is hot to the touch in the morning. I am going to go home tonight and see if my mk2 has the dimmer problem that my mk2a has...
