I was going to start a new thread the other day, but did some more "playing" and got my flashscan working again but seeing as i fixed it, thought i should atleast mention it in here, incase it happens again.
I have 2 x V2 Units, 1 blue, 1 black.
2 x Techedge 2j9 wideband using serial
blue was loaded with firmware .23
black had the latest .26
Problem: I couldnt get afr to come up the scanner or v2 unit's. lambda was working fine, just no afr.
Solution: Upgrading the firmware on the blue one got the afr working straight away, yet it took a reloading of the firmware on the black for it to come good again. this included me powering up/down both units multiple times.
Anyway they are working again now but it was a WTF is going on moment for a while. (I even have a log from a car where lambda is changing but afr is at 0 jumping up to 25, 6 etc)
