JB4 VS Eurocharged Tuning
Hi guys, need some advise. Looking to tune my GLC63 as soon as the first service is completed. Coming from the GLC63s I can feel the difference in power all while knowing the GLC63s still didn't have the upstairs power it could. I did have a w205 c63 with a Eurocharged tune and it was very nice, though I'm seeing some good results with the JB4 and cost is attractive. So I'm wondering which tuning to go with? Normally I always get the ECU tuned since to me they are "real" in the sense they can change things like MPH limiter, pops and bangs as well as finer tuning to timing and airfuel. But does the JB4 with all its sensors really improve similarly and as safe to the point its worth doing over the Eurocharged tuning? I know there is a cost difference but to me I want to make sure I'm happy with the end result. I don't know the difference of power out put between them and if there is any but surely would like to know what else you get with the Eurocharged tune compared to JB4 setup. Any advise is more than welcome. Thanks in advanced guys!

Historically ECU tunes are smoother and safer at least for me.
I can't be trusted not to keep trying hotter and hotter maps on a piggy-back. I was to the point on my Bimmer that I was leaving it in MAP 5 all the time and spending a bundle driving around on race gas or trying to find E85 which I had to test before pumping. I think I finally hurt it and it was a hassle keeping up with the the logs. No matter what we tried it was never smooth at shift points and would fall on its face. I have had the same issues with Audi and JL too.
Now, Bora, seems to have great luck with his so keep watching him.
I would go Eurocharged.

Jb4 is solid for sure
I personally like our full ecu tune as we modify all maps (full throttle/s mode etc) as well as maintain stock drivability Without tricking the ecu. We can also customize things like burbles etc that jb cant.
we have a pretty stout sale for the tunes now if anyone is interested. Just message me

Still waiting for your crew in Orlando to send schedule for our 2020 GLC63. Excited to get in there. Can you share options for what your tune can change including the difference of years?
Our 2020 can not rev past 4k in park or netruel. Can you tune address this? Also this is a separate module (Computer) in the 2020 that effects torque and top speed, please share more information about this is what it does if we get this changed etc..

2020 GLC 63
As I stated in my other thread, I was initially interested in EC tune, mainly because of obd2 tuning and the ability to switch back to stock. However, when I spoke to EC HQ in Huston I was told that the 2020 ECU's haven't been cracked yet for obd2 flash and the ECU must be sent in for bench flash. Additionally, they could not grantee that my stock tune can be saved, just in case I need it later. While JB4 was a PITA to install, it can be removed and back to stock. That said, the times I ran on JB4 on map5 maxed the fuel pressure, so I doubt an ECU tune would gain much more out of the car without fueling upgrade. If I'm wrong, someone please correct me!

Read the FAQ to see the basic differences and similarities between the JB4 and a flash map?

My engineer explained it to me this way:
ECU software is a closed feedback loop, it demands parameters, monitors conditions and output, and adjusts/re-adjusts output accordingly. This helps by keeping output where the driver is demanding at best efficiency, and it helps in error detection and damage prevention. We stay away from one size fits all, or piggy back tunes, for obvious reliability reasons. Piggy back tuning in particular is bad, because it masks values being read by the ECU.
I went with EUROCHARGED. (480/528)

This may sound strange but there is a new modal in the 19/20 effect torque. There is another fee if your remove and modify this as well. Not sure how the JB4 is effected by this or not. Regardless this is what I've heard from Eurocharged. BTW its not low cost its 2k.

Not sure if you negotiated or not but I was in and out for under $1k. Are you sending them your ECU ? I did not buy the My Genius hand-held as the shop is 25 minutes from my house and if I need to do a CYA-Flash (aka MB service visit) it takes all of 10 minutes and will cost me short money to go back to stock map.

@brad65ford what is the WhatsApp group so I can hop in?? I have a Eurocharged Stage 1 ECU/TCU (there is no CPC in my car thank god) on my 2019 GLC 63 and seeing some incredible results. I won't post just yet, as I have a fuel issue throwing codes that is being sorted out by the dealer. Have the intake ready to also go on but not yet.
I have a Mygenius with a MS100 tune as well for even better results but haven't tried until I get the fueling on 93 sorted out.
Thanks for posting!
