Autotune concerns. How will it work?

something i have been wondering. if you have the calculations handy that would be great in case i get some time to do it in future

the usb resolutions aren't as good as the consult ones (im assuming hes talking about streaming data resolution from the Z32 consult isn't sufficient) but it could be worth a shot anyway

Matt,, I believe what Eric was saying is that the output from the speed sensor on the transmission is not of suficient resolution.
I will try to find the email and let you know the speciffics.

Found it...

Acording to Eric the speed sensor signal is only refreshed 2 times/ second.

Even still might be good enough to show if you are making gains or losses.
Will look for the formula.

if you find it ... once i have time i will add it. i dont know what the refresh rates of our ecus are since we get the RAM value directly...

i will use the 2D AFR graph for the KW/HP dyno feature also since RPMs are on the X axis (AFR is on the Y axis and I add another Y axis for KW/HP and torque)
