I'm debating if tunercat better than winbin and I cann't get the demo for tunercat to work. Is tuner cat any easier to understand or to change your calibrations with?
As I understand they say winbin is better for mass air flow sensor. Why is that,or is it?

I've only burned a few chips for MAF cars and it's easier to do it in TunerCat. I believe TunerCat is a lot easier to use and understand then WinBin no matter what calibration file you load in them. My personal preference is TunerCat.

To get the demo to work you'll need two things. First a 32B calibration file for your ECM which can be bought from CATS for 20 bones AND a .bin to play with. Either read the one off your stock EPROM or go to ftp.dyi-efi.org/incoming and look around
