Eurocharged Tune Update




.
480HP/528ft-lbs
.
Anyone running this latest version? Or has this been out for a while? Thoughts?
I spoke to Jerry from Eurocharged Houston about this and he can get me the stage 1 tune that will produce 460-480HP and 520-530 pound feet of torque, but I have to pay a $150 USD reflash fee. I thought I could be forwarded to Eurocharged Canada for free or a small fee, but they were asking for like $1800 CAD, so I was like no lol. I haven't paid the reflash fee yet (because of MBhouse taking a long time for my ECU update). I also noticed on Eurocharged.com, that the C400/E400 #'s used to be around 400HP/432lb/ft. These numbers have now been updated to 480HP/528 pound feet, but the CLS400 still has the wrong numbers (says stock it makes like 500 torque).
I've looked around some threads and the 400/450/C43's all have the same turbos in size, but the 450/43's have a different shape or angle to them. The E43's on the other hand have larger turbos. Many people who get their C400/E400's tuned from EC Canada, get the same tune (the same horsepower/torque #'s) as the 450/43 models. If anything, it's best to just DM people on Instagram who get tunes for their 400 engines from EC Canada, as it's hard even on this forum to find many people with a 400 engine tuned.
Therefore, if you haven't gone with a tuner yet, I would ask both EC Houston and EC Canada for their best prices, and go with the cheaper one. I'm not sure if EC Canada does the handheld. Once I get the new tune file, I should easily be able to tell the difference in power as it will be a significant upgrade +50HP +70 TQ (crank). I've had this stage 1 tune for almost a year and it doesn't feel that much fun anymore because I'm so used to it. I remember when I first got the stage 1 tune, I was blown away and my legs were like NUMB because I was launched back into my seat; I was actually shook. Hope to get that feeling back very soon.




This is very interesting because with stage 1 tunes you're looking at:
CLS400: 480hp/524tq
CLS550: 480hp/606tq
That's very close, for a 4.7TT V8 vs 3.0TT V6...

Either way, the 400 is clearly no slouch!




Either way, stage 1 to stage 1, that's maybe only a 55hp difference, ~80tq...
So either there's something limiting about the 4.7TT (which would *only* be the turbos, IF they are limiting), or the tuners haven't bothered to explore it more.
Its possible to argue the C43 would likely have more tuning interest just because it's considered an "AMG" model as well.

It's possible that it is the turbos, but as I was told, by tuners + car owners, that it is mostly due to restrictive cats and they increase the turbo boost a bit more on Stage 2 since there are no more cats. I was hoping to do more mods and try to reach 600whp lol but things are getting much expensive after Stage 2 upgrade and Idk if I can keep up with them lol. The turbo upgrade is going to cost ~5-6k. Welp. lol
But what one person told me that the tuners can make the tune a bit more "aggressive" and churn out a few more ponies than their listed tune on the site. I totally forgot to ask that, and if I ask that now, the re-flash is going to cost $150.
. Speaking of the re-flash fee, I paid mine yesterday to get the 480HP/528TQ tune. Didn't get the file today, so I'm guessing tomorrow or at the latest Friday.

And yes, I was talking about installing 157 turbos on 278. It's quite expensive, for me. Maybe someday in the future, I might think about it. My goal was to get around 600whp. Right now, I'm thinking about the E85 FlexFuel tune. I need to contact EC about their tune and see what's the best route with the FlexFuel tune. Bc they claim that there's no need to change any parts and it's just a tune. I called them earlier today and believe EC is closed. So I will try to get some clarification on their Flex Fuel tune next week.
Also, I checked their website, and these are the current claims:
Stage 1: 480hp 606tq
Stage 2: 540hp 715tq
What I was told when I got my tune:
Stage 1: 535hp 610tq
Stage 2: 585hp 690-700tq.
That's about a 45hp difference and I want answers lol

. I was only able to step on it twice, so I haven't even gotta an entire feel for it, but I'm pretty impressed. One thing that sucks is that I requested a separate burble tune file as the second file, but I got one file with the burble. I have to pay another $150 USD to get the tune without the burbles. A lot of people don't have issues with burbles w cats but I like to play it safe and I don't want any issues really. Might just put it on for the summer. I'm pretty sure that as long as I don't let it backfire then it can do absolutely 0 damage to the cats anyway, as when you drive normally whether that be in E or S, it doesn't backfire unless you're specifically looking for it to do that, or if you're in manual. On a side note, I hooked my main battery up to a battery charger (12V 8A) for about 5 hours last night, and for my 12km commute, it was working at about 80 degrees C on the coolant scale. Normally I would have to drive the car for at least 15 minutes for the battery to charge up and for the function to work.

that being said, C&D tested the CLS 550 stock at 4.2s to 60. Pretty sure with dyno mode on. and the CLS AMG S was really fast at 3.1s /11.5




On the 550? Who'd you go with and howd it go?
