Funny and a big secret of mine with the local kids who challenge my 19 year old Sub
They've come back with tunes and then are competitive out on the local boulevard
I don't go out looking, but hardly ever pass up a good one....but
at +163K miles...it is no longer able to smoke the tires :(
Why these time to distance is so out of it...as it has a huge new set of variables
Fly by wire and total computer control over just about every aspect of the
throttle. Even the butterfly is no longer directly linked to the throttle cable,
as there is no longer a cable
Then even the various tuners have their own levels of safeties and that is yet
another variable
Do their stuff kick in before closed loop? If yes, then how do they
manage the thermal safeties?
Do they manage CAT temps and do they then do what the OEMs do by
fueling more...not for the combustion, but to cool the CATs
Do they know the rate of change on the throttle and then mimic what
your foot is saying via the throttle or do they stick with the OEM's
dialed in hysteresis? Or is the potentiometer on the throttle capable
of transmitting that rate of change well enough to know what the foot
has told the throttle?
and a big ETC on that stuff
