i dont have many reviews, on amazon almost none, i boycott them now, (and deleted all my 100s of reviews there)
i do not review, elm 327's , unless real, 99% are not,,,, real costs 3 times counterfeits.so... be waste reviewing the 1000 sold on ebay. and same junk on amazon sold at 2x china prices...
yes,,have many 02 pages
so one can see lots of scan tools usages there...
the faster the tool and ecu the better are the 02 plots.
voltage over time.
if it swings around 0.45v its good. and low and high
what the tool does is scan the 02,then does so real fast in a loop (software)
then digitizes it. (fills in the dots, like a scope but very crude) so it can miss some swings, this ok
on 2008 cars,its way faster.. can-bus fast.
errors:
swings are shifted wrong up or down.
dead 02(or its heater)
dead cruising. (light0
stuck at 0v
stuck at 1v.
slow 02, the old do that, all do.
