Hi,
I have been using a OBD2 reader and TORQUE on my smartphone, and really like all of the data that it displays. I also have the readers on my other cars: 2009 GMC Yukon (It also reads Ethanol %), 2001 Corvette, 1997 Lexus LS400, and my 2002 Jetta TDI automatic.
I can watch the transmission temperature, MPG Instant, MPG Average, Intake Temp, GPS Speed, Engine load%, Boost Gauge, Fuel Flow GPH, and Intake Air CFM, among others. There is also a Timing Advance, which is usually -1 to 1 degrees advanced, but I have seen it as high as 4 degrees advanced with some cetane booster. The PO said it had a chip (not sure of brand), and some high flow injectors, and stock turbo that I had rebuilt a year ago. The mechanic who was a factory VW mechanic for 20 years before opening his own shop did the timing belt service for me, said that it was the fastest TDI he had ever driven.
I know spark timing advance in gas engine really helps the engine rev up, but with a diesel, the only timing that can be adjusted is the fuel injector pump. What is normal timing variation in an ALH TDI engine?
