Would something like a Schwaben or fowell scanner be any good? Or is that just to read codes from cels?Yes ODBeleven is easier for doing tweaks not as many steps as with Vcds. Vcds has a great forum and if you get verified you get complete access to post anywhere on the forum and ask for help. You are automatically verified when you by their tool from them or distributor. If you buy a genuine used vcds scan tool you will need to pay $90 or $100 to get verified so you might want to consider that in the price of a used scan tool.
