[Diy_efi] Engine Tuning system, "The Australian" Wed June 14, 2006

[Daniel Nicoson]

Quite honestly I haven't seen too many articles of that length that use the
word "actually" so much!  I thought it was my 15 year old using the word
"like"...

Snake oil.  I only read the first link.  Whoever is posing as the
"information" man doesn't have much grasp on what a modern ECU is capable of
doing in the tuning department.  I suspect that most of the
US/European/Asian automotive engineering staffs are quite aware that there
are torque meters available that could work in an automotive drive train.  I
would suspect they use those in some of their testing.  The fact that they
don't use them on production vehicles probably means there is not much to be
gained.  They don't give up much these days when it comes to making a car
efficient and "clean".

I'm not saying someone can't find ways to get better mileage or even cleaner
emissions but based on the first link's discussion, I don't think that group
is going to make huge improvements with a torque meter and another feedback
loop.

I wouldn't mind if they prove me wrong but I doubt they will.

My $.02

*....Because when you actually drive your vehicle out of a showroom, the
vehicle has been set up with these static maps. Now these static maps have
been developed to mimic the conditions that are expected to be placed on the
car, so the temperature, the speed, the revs per minute, these conditions
are all built into these static maps. So once you drive out of the showroom,
your car then starts to deteriorate as you drive.....*

CHOP!

The only automotive computers incapable of making fine adjustments to fuel
and ignition curves are controls modules which did not come equipped with
closed loop monitoring and that type of engine controller were mounted in
cars manufactured in the early 70's. This may be a snow job!
