Good to hear you've got it loaded and operational. I had the same messages (and you will each time you change between tunes). Strangely my CLS550 also had the odd odor at first. Hopefully, it doesn't destroy the cats! I'm due next Feb for an emissions test and I will definitely change back to the MB tune. You will be shocked at how much it changes your car! Enjoy, Marv
Thanks for the responses to my questions about the battery charger. I’m using it just to be safe.
On a side note - I just applied my tune. It got scary for a bit because while the file was being written to the ecu the car started complaining saying the vehiclenis inoperable. Do not shift gears. Do not drive. Go tonyour dealer. Eventually after the upload was complete the messages went away but joine warned me about that. I’ll call EC tomorrow tonasknif thats normal.
I’ll drive the car late next week for the first time. Tonight i just fired it up to take a listen to the burble. So far it sounds throaty and kicks in on downshift at about 3k. I asked them to go mild on it. I like the way it sounds but not sure i will stay on the burble tune or just regular tune. Also, smells. Like a bad bbq. Hope that stink goes away after the car gets used to the tune. I’m definitely flashing back to stock whenever i have to go to the dmv.
you know how they are in New Jersey about that inspection sheesh but from what I’ve heard it’s pretty easy to flash back also how long did it take to load the tune?

Thanks Marv. What mode do you normally drive in? Eco, manual or sport?
I am interested in getting a tune for mine this coming summer and I can't decide which brand to go with. Who has any of these and what are you experiences so far, good/bad? What mods you had to do due to the tune? Change of any gaskets or replacing any other parts?
Eurocharge: $1400 = 530hp and 606 tq
Weistec: $1500 = 540hp and 715 tq
RennTech: $2500 = 540 hp and 705 tq
What i don't understand is the pricing. RennTech is overpriced, though it is a good company. Weistec gives same number but with way less cost, anyone has Weistec tune? Is the trans able to handle that much tq? Anyone who has RennTech can maybe shed some light?
I'm between Eurocharge and Weistec and their prices are pretty much the same, but big jump in torque.
Did you guys have ANY kind of issues regarding the tunes?
AND has the gear shifting changed at all? Is it more quicker or about the same? What other changes did you notice the way the car behaves?
Mine is RWD, btw.
I wonder if we gonna see some black Friday sales on tunes this year.
RaceIQ did my 2017 CLS550.....ABSOLUTELY insane and no issues whatsoever..midrange hp and torque is night and day, turbo lag is gone, and honestly you gotta watch it because it'll break loose if you stand on it quick...more info later, but they are in Atlanta and you can find them on YouTube. Has a obdII tuner too.....great performance...outstanding. RaceIQ has the ability to change shift points, exhaust feedback, and parameters you might want to move around. They can move the top speed govenor, push the red-line a little higher, and other things. Basically you tell them what you want and they'll tune it to your desire. I chose to not push red line or shift points at all, and it is a bullet, but can be driven sanely and nobody will be any wiser at a light that you can leave so hard that it will be like they are painted on a rock...
