Pulled this today out of my truck

Cool, thanks.

Good to know MPVI3 reads and writes now. I did a PCM swap last year for my 24 Australia market Ranger Raptor and been tuning with HpTuners since. Will plug in the original PCM and try a read when I get time.

Since the last few hours I've been unable to rewrite. Failed to process flash data.

Might not be related, but have you also tried to update the MPVI3 firmware? I connected to mine via the TDN phone app yesterday and there were new firmware and resource updates that loaded. That said, I have not tried reading or writing on my truck yet due to work travel.

I updated firmware before I did the initial read.
I think I figured it out. I was flashing on the road, via my phones Hotspot. I believe I am near my limit of my data because everything was loading very slowly. I got back home and had my laptop hooked up to my routers WiFi and it worked fine and noticed it loaded much faster

I also noticed that the scanner will not let me start recording if the truck is moving. At first I thought it needed to be in park. But I'm assuming it's some kind of safety feature and it won't work unless MPH reads 0.

Cool, thanks for the feedback. The reads and writes do need a good connection to the internet indeed. I believe reads are essentially virtual reads based on the vehicle's VIN number.

[Pistol_91]

No problem. I think you're correct
