First mods order going in: Need your help picking ECU plz
Yes, I realize there are hundreds of threads spelling out which ECU is better and such, so im sorry to create yet another to gather feedback. Heres my dilemma... I have a 19 c43w that I just want to get more guts behind.
Its a daily driver, so im not looking to go too crazy, but today is the day for me to make the order.
Im eyeing a true ECU most likely, not a piggy back unit, unless its Kleeman's KBox. I have been told everything, up one side and down the other, but honest to god, I have been out of the game for so long, I just dont know what to do.
Ill be adding the MST intakes and some sort of BOV (yes, i know it doenst add anything, but i love the sound) at the same time as the tune.
Later on, ill likely through the AWE touring exhaust on, but ill start small and end bigger.
Your help is much appreciated1

Looks like the JB4 would be perfect for your use. You can change between 5 different maps based on your preference any time you want. You can go stock any time you want as well with a push of a button. Also JB4 has the fastest trap speed of all the tunes till now.

I'm with Munis. What sold you on Kbox over the JB4? It's admittedly anecdotal based on level of chatter, but JB4 seems to be installed at least as much as any ECU flasher out there.

JB4 is hands down the best tuning box for the C43, years ahead of everything else out there in terms of features and performance. That said it's true a few things (like exhaust burble, speed limiter removal) can only be done via re flashing. If not worried about lease return, warranty, or resale, flashing is a great option. And the JB4 is also compatible with all flash maps for fine tuning, logging, boost by gear, and features.

So, i have looked at a lot of tunes, and then all of the sudden this Dinan somehow came to my attention? https://www.dinancars.com/product/d4...mid=C43%20AMG/
With a simple search, it appears to have solid gains for $325. WTH am i missing!

JB4 can be as simple as the Dinan or as in-depth as you want it to be. Depending on your fuel access, map5 & 7 offer even more aggressive gains that don't require any major tinkering. It's also more than just a tune as it allows reading and clearing of CIL codes if ever necessary, as well as very detailed logging. BMS will also walk you through custom map6 tuning should you ever want to dabble further. Record and send a few logs their way, they'll come back with a tuning recommendation to get you started on creating a custom condition-specific map for you. No other flash tuner is offering this level of involvement or map control for anywhere near the price of the JB4.

It's like a more limited version of our old Stage1 tune. No fuel control, no CANbus, can't even read pedal input, throttle, AFR, ignition advance, or engine speed for tuning purposes. Doesn't even adjust both boost sensors. It's better than nothing but no where near what a JB4 offers.
Is this something you would be willing to speak with me over the phone about? I have done your online chat service, but frankly im a bit of a novice in this arena and need more info or clarification I suppose. Im ready to order everything, just want to fill my mind with more info.
Thank you in advance!

Yea nothing put problems they don’t know what they are doing and customer service is ****. Matt just tells you what you wana here. Car never ran!! sent ecu back and forth several times. They told me to go to dealer to have them reset ecu. Dealer made replace ecu to avoid warranty void on 2019 less then 1000 miles biggest waste of money and time to just be back to stock.
Join the club buddy. Should have searched a bit more. Search for my channel on youtube. munis c43.

Sorry to hear what you went thru. I had very good experience with them and Matt checks in time to time to see how the car is doing. I dont have a 2019 but a 2016 450.

Why isn’t AMR making the power on 19’s. Is it possible they were not making that power ever? Renntech told me they are using same tune as the previous cars. Making the same 416 horse on 93 octane fuel. They said a minor ecu remap from the factory is the reason for the minor horsepower increase on the 19’s. I don’t want a piggy back so JB4 is out of the question. Renntech told me the tune is very noticeable and they did test it on 19.
How is AMR and Eurocharged making so much more power. The other ecu tunes Renntech offers for the other models are making the same big increases as AMR and Eurocharged. Is the car just maxed out with Renntech or are the other tuners trying to make this car into something it isn’t and maybe break the car down the line.

Yea. I did look them up. I’m gonna go Renntech. I just do hope the tune is noticeable. I only have 250 miles on the car. I really don’t drive a lot. I live and work within a few miles of each other. Is it to soon to even consider tuning?

Also if you are driving only a few miles everyday, you car is not even getting enough time to warm up to working temperature which will allow you to push it. Go to AMG menu and wait for the temperature numbers to turn white from blue before you start pushing the car.
I have no idea why you are opposed to JB4, but in your requirement, it is the perfect tune for you. Cause you keep it in Map 0 (stock) for daily driving and if you are going for extended drives, only then switch to higher maps. It is still one of the fastest tune for this car when you want to be fast, and when you want to be stock you can be stock. All this you can do in seconds from the mobile app. But either way Renntech is a fantastic tune too.
