GLC43 best tune that can be installed and removed
I have a ‘18 and do not want to void warranty. I’d also like to have an even better driving experience. There are many threads on tuning but none specific to this topic. I know there’s a lot of knowledge on the forum so I’d like your help. Thanks!

Get a used ECU, clone it to your vin, load the tune on the clone, and enjoy the ride. Just make sure to swap before you take in for service. I've heard this does not guarantee the dealer can't discover if you ran a tune but makes it very difficult to detect.

If maintaining your warranty is important, I would not venture into the world of tuning. You may find a sympathetic dealer but you also may find your dealer not so friendly. If you do go for a tune, I am extremely happy with the handheld unit from AMR. Apart from the change in performance, it is possible to restore the factory tune at will.

If a company actually put out a flash tune product that dealers couldn't detect that company
would be rich.
I will just have to be patient.
My racing days are over.
Would love to see if there is actually anything out there.
I think from reading a piggyback is the least detectable but I am sure someone will say they are- LOL.

You have a few options. You could easily get a virgin ecu have it cloned and tuned and just swap ecus for a dealer visit.
We do also have a handheld that allows you to tune from home and also stores your stock file to flash whenever you like. While we have done tens of thousands of cars before without issue, if they want to send the ecu to Germany they could find traces. (Piggyback no different)
for the gentleman that said he tuned at the dealer and no worries, it really is a crap shoot. There are quite a few people that have done that (search the forums here) and found that they got black flagged.

Uh..... so your dealership will tune the car for you ? Did they put limits on the threshold of tune , i.e. they won't go beyond a mild bump in power ? Just trying to understand this, so they will take, for instance AMR's software, tune your car and then if it goes boom it WONT void the warranty ? Never heard of this before.

Make sure you get it in writing about their warranty. It will be a dealer thing to cover issues that result from the tune, not MB, if something happens. JB4 would probably be the least detectable tune, but even then, if you blow your engine, MB can find out and deny warranty coverage. Good luck.

After all the feedback - I called 4 MB dealers in the area. All of them offer tuning and all of them will return to factory settings if warranty work is needed. They said unless customer is a jerk, they don’t really care because they get paid for the work. Has anyone been denied warranty work because of a tune or is it urban legend?

There are other piggy backs like RaceChip GTS, Dinan, and a few others. I am not sponsoring JB4 but, I do like the implementation and ease of removal with out having to plug up ODB2 devices to keep flashing to stock when needed.

Dame how has the lowering module been working out?
Is it always at static height and aligned at that height ?
Also do you find more rock chips on the car overall as a result ?
These run flats stick to any loose debris and just throw everything back up onto the car.
I was riding with the windows down with my hand out the window and kept getting pelted by rocks.
I am dreading what this thing is going to look like in 5 years.
Either way thanks for the JB4 piggyback info and it kind of re-affirmed my original thought
that most are detectable but the piggy's have a tendency to raise less eyebrows.

Let me know if you, or any of the guys are looking into the JB4. I am in a WhatsApp group and I can invite you. I did Service A and B and did some warranty work and I have removed the Jb4 each time. My dealer is mod friendly so after I install my downpipes, I am not going to be removing and reinstalling my JB4 anymore as I will just leave it on. It's out of site anyway, you would have to really be snooping around in my engine bay to find the device though my dealer doesn't care.

Have had mine since October 18 and just turned 5k on it- LOL (no Service warnings yet) . Yeah I am strongly thinking paint correction and Expel. Curious, on the JB4 is it totally customizable or are there preset tunes you choose from ? What are the gains ?? I am no mechanic by any stretch so how easy is it to set this JB4 up ?

JB4 is preloaded with map 1, 2, 5, 6, and 7. Map 6 can be adjusted for peak boost and BMS is currently working on fuel stuff. The guys in the Whatsapp group are constantly trying to perfect map 6. The best of the c43 guys are running 0-60 3.4 secs and quarters miles of 11.4 121mph+. So it's definitely making power but how much?, it varies from car. On my end, my bro has an audi s5 and I run over him all day and he has a stage 1 apr tune (it's not even close). JB4 also has phone app so you can change settings on the fly, I run map 2 daily or when I feel the need for speed I add a little race gas and run map 5. If I am out with the wife, and I get a little tipsy, I have her drive and set her to map0 (no tune). The guys in the group are very helpful and will check your logs, provide suggestions and even show you how to install the jb4. Took me 5 mins to install mine, because I wanted to zip tie everything to make it look OEM as possible.

If I tune, it will probably be with JB4, so good insights here for the GLC. I'm fighting the itch, though, to dump the 43 for the 63. Car addiction stinks.

I seriously don't think about the 63 at all. I got my 43 for $25k+ less than a 63. The 63 will always have the bragging rights because of the honking V8. I can live with that.

Renntech The hand held tuner can be installed and then removed at will. Just make sure you have a tender handy during install. I have a few tuners no issues what so ever. I would say those who do have fuel issues/maintaining proper octane.

Thanks, didn't realize they had the HHT for the 43 now. Oh boy, decisions, decisions...

If you want to play it safe then Renntech is probably the best choice since they provide the HHT. Other vendors will provide you with the HHT but you have to return it once you tune. Another option is to go on Ali Express and buy the Mercedes Star Diagnosis System (SDS)tool. Then you can just flash the Renntech, Eurocharge or AMR tune yourself. The only problem with the HHT devices is that if MB really wanted to do a deep scan search, we have found that with using the MB SDS tool, there's a section that shows Flash Counter. This flash counter let's MB know how many times the ECU has been flashed. I doubt MB will be digging that far but if something ever happened where you had to get like an engine replaced or transmission or something major, it can be detected . Now, not saying that the JB4 is not detectable, but I rather not be flashing the ECU imho. If you don't care about that then the ODB2 tunes are great.

also, you won’t be able to apply our tune via star FYI. Most of the tuners files are encrypted for the devices we use.
