I will be double posting because the Ecomodder website will time out your token if you take too long typing. If you have not saved it, you will lose all your work. Also, I do not have a build thread so I will be mentioning some mods and how they relate to Eco-driving.
The first thing I did to improve mpg was to air up the tires. The original Goodyears are rated to 44 psi and I increased them to 50 psi. Later I backed off to 46 in the rears as they have less weight and forces acting on them. I am amazed how far this car coasts. Coast whenever it is practical. This is one of the easiest ways to improve your mpg.
The second thing that is a must is instrumentation. I purchased a ScanGuage II so I can monitor coolant temperatures, instant mpg, intake air temperatures and current and tank mpg. I wanted to be able to monitor engine temperature since I knew I would be blocking some of the radiator grill. VWs have a temperature guage in the dash but it is damped from the factory. In other words, it gets to normal and stays there. A ScanGuage or UltraGuage gives an accurate digital readout of engine temperature. This is vital to driving the TDI efficiently.
If you read about Hypermiling you may encounter some terms such as pulse and glide, DWL, EOC, DFCO and ICE-OFF. I will discuss these and how they relate to the TDI.
