Title says it all.
Living in Europe corresponds to high gas prices, so i was wondering if an ECU remapping might save some money in the long term. Also… are there any negative impacts on the engine or other parts that should be put in consideration?
long term, friend of mine wants to weld on some more metal to the camshafts of 1.9L TDI engines, to keep the intake valve open longer so some of the intake air is blown back out. you then modify the pistons, or the heads, to get the compression ratio back up higher. essentially making an Atkinson cycle diesel engine.
there are many other efficiency improvements to start with before remapping the engine, unless you have a truck and people have already provided better off the shelf solutions. its not nearly as easy as it sounds.
