Fuel Efficiency and the Yaris

[Boost Addicted]

''Collects very well''? Did I read that correctly? You use a $200 scan tool that has 5 buttons to figure out all the necessary information? Soo... Can you read fuel maps/trims? Read individual measuring blocks for injector pulse width and duty cycles? Open and closed loop? Monitor and log multiple sensor outputs? Suggested vs. actual MAF, MAP, TB measurments? ... Do you even have wideband oxygen sensors to measure your precise fuel combustion? Oooor... Do you just have some magic program that calculates fuel mileage? Cause I have that on my dashboard in the Jetta... I don't need a scan tool to do this. I can just go ahead and do it for you if it's gonna be the same thing.

Come back when you have a TIS Techstream.

Until then, Mr. Burgman, you can get yourself a nice magnetic drain plug, and again, as said before, drive one cycle of 5000 miles driving cold, right off the bat... No waiting. Then another 5000K miles letting the car warm (in winter months), or giving her 10 seconds minimum for proper distribution of lubrication if in summer months, then compare volume of metal material on the magnet.

If you don't give a damn about engine wear and all you care about is fuel mileage, then by all means let me dismiss this situation now... Because you've got larger problems in life to deal with if you consider engine wear<minimal fuel savings.
