Finally making headway, thanks to Jesse, with the cutsom OS 3/bar application on a wild TT C5. What I am totally puzzled by is that the car has a 3 Bar MAP sensor but runs like crap with the scale set at 288. The FS reports a real high Kpa reading . When changed to 194 (2 Bar) it gets closer and finally at 94 it runs great. WTF??

When the scale is set to 94 the MAP reads 102 KPa with the key on. What is the problem?

Also I am disappointed with the Autotune tutorial as after 4 times going through the steps it still wouldn't run. After Jesse got involved I realized there ae things that need to be done that are not discussed. Needless to say I got a good lesson tonight!
