YOUCANIC UCAN-II-B
I am considering on purchasing the YOUCANIC UCAN-II-B PRO Full System Scanner (see link below) for my 2014 E63S AMG:
https://shop.youcanic.com/products/u...43664225992853
I can't find many reviews on it, and I know they are a fairly recent addition to the OBD scanner world. I am willing to give a new company a chance but don't want to end up throwing money away.
From looking over what the scanner can do on their website, it seems like an amazing tool (probably the closest thing to Mercedes STAR) but for way less.
I would like to hear back from members that actually have this YOUCANIC UCAN-II-B and get your opinions and thoughts.
Thanks kindly in advance all!

So while I'd be tempted to get this just to see what it can do, like changing my stupid turn signal from 3 blinks to one, I'd like to see what the other models offer first. I don't suppose anyone knows?

The Best of Mercedes & AMG
- The problem with newer Autel scanners is the initial cost over $600 and the annual subscription which is rather expensive for a DIYer (about half the price of a new scanner).
- BlueDriver is nice and portable, but you can only scan and clear codes.
- XENTRY is clearly the best to have, but requires multiple components and is large in comparison.
- iCarsoft MB V3.0 is superior to iCarsoft MB II.
- If you want a scanner that fits in your glove box that will do 99% of what you want done, get the LAUNCH Creader Elite 2.0 BENZ.

It ended up being the hard work of Cayman/Boxster owners that finally convinced the 911 group. The leg work was translating the German from the PIWIS to English to understand what the 'equivalent items in what menu related to'. The Thinkdiag is all in English and super easy to use.
I expect that the cost to code bi-directional and do most maintenance will continue to drop.
Willl look into the LAUNCH for the E63. Thanks.

I've lost respect for Xentry since the car can check clean but still have issues. Like when the rats chewed my wires, the non-functional module did not show up on a scan. I had no clue wth was happening and eventually tried pinging my 48 modules one at a time to find it. Hours later I did, but why can't it just say; Hey, this module ain't working.
My Keyless Go checks as good, but does not work.
Autel and even my HP Tuners can see codes while Xentry says there are none.
It has some interesting features, but even the dealer cannot find any issues with any car I've taken to them. So it seems to me some other device(s) will be better.
Red; I'll try the one you suggested, thanks

I ordered it, be here Tuesday.Same deal happened as always; I see this other one for a bit more $, hmmm, what do I get for that? Or this other one for $200, or that one for $300!? I had to turn my brain Off, go into autopilot, and order the one Red said to get. Thanks Red
I've been using my Autel to clear codes but it takes like 15min, so hopefully this will be a faster? One signal blink and Eco Off would be worth the cost of the unit, so fingers crossed!
I don't suppose anyone knows about smogging with a change like diff turn blinks, or Eco Off, or anything at all for that matter? I can find virtually nothing on what you can and cannot do to a car and still pass the checksum test in California. I don't care about being legal, I care about failing, which is a hassle and $50 a pop. I figured someone must have done some tweak using this, then smogged it in CA? Anyone?

Then if you ever need to restore it you have the backup to restore from to pass all sorts of test. I am not sure if it will restore it fully and don't affect the checksum but maybe. I am not familiar with California law.

Also killed fuel on decel, will check tomorrow if it actually does.
I didn't see an option to turn off the E mode for the tranny, but one of these days I'll get that pesky bugger...
I can see if it upsets the checksum, it's just time consuming and I was hoping someone got a smog check in CA and could say yes/no. My ecu is backed up on my laptop so if all fails I can always re-Ghost it, if that's still a saying.
CA law is super easy: If you're smiling when you're doing it, it's illegal. I'm always finding more things that are illegal, like I recently discovered my pocket knife is illegal, and I probably have 20 various kinds. Per the letter of the law I'm committing enough crimes, as I sit on the couch as write this, to put me away for life. Nothing actually bad, they just make everything illegal. And it's guilty until proven innocent, they need zero proof. Learned that the hard way.

I've seen some youtube vids where people did the AMG thing. I wasn't interested so I forget the details, but the guy had to pull the inst cluster and do some soldering. I'm sure it varies with model and year, but BenzNinja would be the guy.
My fuel cut didn't take
No biggie, just did it to see if it would. Might take a second stab at it since it was mentioned that it might a try or two.Anyone find anything else cool to do with this tool? I saw a lot of light stuff, so I may try to turn off all my interior lights/trunk etc that I currently have unplugged. And turn off my door sill lights because the observatory 100 miles away is complaining about light pollution. I put making tape over those F'in things on day one because you open the door at night and kiss your night vision goodbye.
Turning Eco Mode off ruins the checksum/CVN. An issue if you need to smog check in California.
Decel mode to kill fuel didn't work, had no effect on my car, but does ruin the checksum.
The turn signal change to one blink did not hurt the checksum.
The HP Tuners patch does not affect the checksum, which is good news since you can't uninstall it.
The backup function in Launch to restore settings did not work! I tried it twice, it does zero, nadda, nothing. It says it worked, but it did not. So note to all; use Launch to check the oem CVN #, take a picture of that # and save it! If I manually restore the changes I made then the CVN/checksum returns to oem. So for me, that CVN is how I can tell I didn't miss anything. And yes, Calif checks the checksum! Ask me how I know... Apparently they don't check all cars, but of course mine is in the system.
The Eco Mode and Decel are stored in the ECU, meaning I swap out the ECU and the Eco/Decel changes vanish. The turn signal mod remained. I figured this would be the case but had to check because you never know with these cars.
I recently bought the YOUCANIC Diagnostic Scanner, and so far I have been very happy.It’s already paid for itself. No yearly fees, just a one-time purchase. It cleared a ton of stored codes and identified a bad left front ABS wheel speed sensor, which had turned my dash into a Christmas tree. Now, I’m using it to chase down massage seat issues. It works on all vehicle systems (engine, transmission, ABS, SRS), and is super user-friendly. I’ve used it on my Mercedes and Freightliner Sprinter, and it’s great to know I can use it on my Honda Civic if needed.
The company offers a lot of helpful how-to videos for Mercedes-Benz cars, which is a nice free added bonus. It basically is in par with Star for diagnostics but easier. The only thing that Star has is coidng capabilities but that was always a challenge so I don't think I am missing anything.
Highly recommend it to anyone looking to take control of their car maintenance.
