I would like to know if the devs over at HPT have thought about adding a feature to adjust the accelerator pedal input smoothing?.. I am pretty sure that there is a buffer of some sort that holds a specified number of readings taken from the accelerator position sensor and it averages that buffer and that is what gets used to set the throttle.
Having a way of adjusting the size of that buffer would be a really nice feature to have especially on vehicles that have drive by wire when it was still a newish technology. The ECM's were really not up to snuff in terms of speed and the buffers were to large so you ended up with throttle response problems. Attaching a device to the accelerator position sensor that offsets the value is not the proper way to go about doing it, and those things don't do a thing when you mash the pedal to the floor.
I do not know how large the buffer is, what I do know is that my 2008 Pontiac Solstice takes quite a long time for the throttle to reach 96% when I mash the accelerator to the floor. I am not taking 2 second, closer to 5 or 6 seconds if not more. I would have to go back and check.
As an example, If you have a buffer of say 40 values and all of the values are at 30 the average is going to be 30. then you add a value of 90 to that buffer. the averaged amount is going to be 31.5 it is gong to take 39 more readings of 90 before the average is a 90. That is going to cause a lag in the throttle. This is done to help improve gas mileage because it smooths out fluctuations caused by a persons foot. I don't think the people using HP Tuners care to much about fuel efficiency.
I know that I would rather have as close to real time throttle response over MPG.
You can thank the EPA for this wonderful gift...
I would think that there has to be a way to adjust the size of the buffer or even eliminate it completely..
