Hi all,
Is it me or am I just expecting too much from my $400 programmer and $500 custom dyno tune? Why is it exactly that there are some good gains to be had by simply fine tuning the A/F ratio and timing for a particular car but nobody has really solved a few basic issues like throttle response or driveability and improving part throttle low load fuel milage?
Another problem is that the '05 GT's ECU is not helping us out any with a processor and firmware that have so far resisted increasing horsepower via the same means that have traditionally worked well in previous engines without this new ECU. IMO the truth is that to virtually EVERY tuner in the country, the new Spanish Oak processor is a blackbox they don't really understand and cannot fully control so they hide their lack of knowledge on the "mysteries" of the ECU's logic.
All it seems like the CAI manufactures and dyno "tuners" are really doing is adjusting the way the way the MAF sensor sees the airflow for various MAF housings and CAI piping and changing the ignition curves, inital timing advance to work with their products. Nobody as far as I can tell is really reworking the ECU parameters fully to optimize power and drivability. Nobody is reworking the way the GT's 3-valve cams retard or advance under load or part throttle. Nobody has removed the fly-by-wire throttle's feeling of being a little distant from the actions of the gas pedal, ie. when you lift the engine doesn't chop the throttle blades like I did, they linger open for a bit before coming down.
Just wondering out loud.
Cheers
