ok so yeah, that means it truly has little to do with the processing ability of the computer. Now what I can't figure out is, if that is the case, why is it taking 4-5 minutes on one and 1 minute on another

Because on the mbp, it has to go through another software layer (bootcamp firmware) that emulates compatible hardware for window to run natively, thus more processing to get from ProECU to the usb port. Bottleneck.

That's my theory anyway.

I'm on my phone so if I make mistakes, blame Sportsguy83

Good theory but I'm not so sure. When I boot natively to Windows the flash goes very quickly. ~2 minutes. Early 2011 MBP Core I7 2.3ghz 8gb RAM 480gb M500 SSD. It only goes very slowly (roughly twice as long to flash) when I am running in VM.

At this point, I'm pretty sure @mad_sb is correct, it has to do with the chipset, drivers and optimization.

Now if only we could get rid of the ecutek dongle, maybe sell cables with dongles built in.

An intel-based Mac in boot camp is as native as a regular Windows box. There isn't another translation or abstraction layer.

A quick follow up, when I use the built-in port on my mac its takes 3+ minutes to flash, using a usb hub (targa 4 port) brings it down to 1.5 minutes. I think someone else mentioned it.
