Had my vcds a few days now, learnt how to do some logging by searching the forum, but can not find any real information on checking the data on my logs, e.g. I have learnt timing pull should not be more than -5 and requested boost and actual boost should not be more than 50 mbar plus or minus, and fuel rail pressure requested and actual should not deviate by more than 5, my question is there a online manual or link to show all the measuring blocks ideal numbers, e.g. what they should be and what is excessive and could be a problem, thanks in advance
