Omg. I wonder if that was just a spare or some other guy with an E63 is now wondering why his car won't start either?
As long as yours is still on their bench then it's a good thing, it should be plug n play. I assume you already asked them for it?

My thought process as well, although if it was someone with a E63 then they would have had to say something it’s been two weeks since HP tuners had my ECU. I reached out to HP tuners they asked for an info log which was sent. TunedMercedes replied and said since they’re identical, they work the same and that he payed me ( my second partial refund) to take it to MB to get flashed🙃🙃. Fingers crossed HP Tuners doesn’t drag their feet with this, the ECU I thought was mine is currently at OE tuning. I’m going to buy a used one and have OE virginize it.

If things fail with the dealer, you should reach out to @BenzNinja as he is able to un-brick control modules that have been hosed up.
I'm curious what OE Tuning is charging to virginize an eBay ECU.

So my ECU is currently at @ OETuning, there is no way I’m paying 2k at the dealer. So initially 900 for TunedMercedes to brick my ECU and waste my time,300 new battery, 1500 in rental fees. 1600 for OE recovery, stage 2 tune, flasher and one day shipping both ways. I’m assuming a used ECU is 150-300 so in the end let’s say 4300-4600 bucks men. I appreciate the referral OE has been great so far I'm hoping for a resolution before midweek. A guy just wants to drive his V8 Benz in peace !!

Much appreciated I’ve heard of your work and you guys are definitely pros! When I get my M278 running I’d be looking for some coding to be done lowered, sports + etc.

UPDATE
. After sending my ECU out to get recovered I was just informed that the ECU HP Tuners sent back to me is from a M157 with a Renntech E63s stage 2 tune. That would be great if a had a M157, so now I try to find out what happened after I shipped my ECU the first time. 🥲

HP Tuners admitted to making the mistake of swapping my ECU and the M157 ECU. Just emailed them the tracking number and they should receive it in the morning. Fingers crossed I can get reimbursed for these one day shipments.

OE Tuning successfully stage 2 tuned my ECM and the car is running beautifully, the turbos spooling make it sound like a spaceship! I’m eternally grateful for the whole OE team they made a stressful situation 0 stress!! Despite HP Tuners sending me the wrong ECM they did reimburse my shipping costs and they did recover the ECU when it was initially sent in. Lots of lessons learned but I’m not deterred I’m looking at M157 turbos next!

Take the win and the LESSON LEARNED (or not learned). Not sure if this is your daily driver or if you depend on it for your livelihood, but daily drivers should not be project cars.
Still, congrats on getting this resolved and sharing your experience. It's your car and you should do what you wish. I have a tune, also, but I'm retired and my risks are different. I considered the Weistec turbo kit that bumps my HP to 540hp from my puny 3.0L bi-turbo M276, and if my turbos every fail, that's the course I may take. I worry, however, that the 570 ft-lbs of torque will wreak havoc on the drivetrain. So, for now, I'm content with 400+hp from my @VividRacing VRTune.

I hear you and I agree !!! And definitely purchasing another daily soon because of this. The way E55 prices are I may go that route, the gearbox absolutely needs to be addressed. I’ve been looking at a couple WISTEC kits.

You can hear your turbos spool? I've never noticed, I guess I'll need to pay attention...
So an OE Tune stage 2 ay? What is that exactly? I bought their tune three? years ago and it was a MyGenius with a regular 91 octane and a 100 oct tune. The 91 was the same spark timing a stock, so it does not work well on 91.
The 100 was the same tune but 2.25deg more at max load. I was able to exceed that timing using 50% ethanol but I'm sure what my octane is using the R+M/2. My guess is somewhere between 96 and 100, but whatever it is it works.
I wonder if yours is the same as my 91 or what? When you make a pass I'd love to see the HP scan of it
I can post all the settings I use to read the data, if you're interested.
Always wanted M157 turbos, just too much $ and work. My boost at 6k is 12.5 so I've wondered what it would be with 157's. I don't suppose you know?
Also wonder what downpipes, with the oem cats, would do. Maybe pointless? Seems everyone that does it takes the cats off so I can't get an answer.

Oh I sure can my exhaust setup has been a cat delete + H pipe since day one almost 10/10 would recommend biggest downside is if you were untuned like me you’d definitely lose boost. I’m tuned for 93 I’m sure I’m mid 5 ish I’ve been data logging of and on. 157’s 17 psi of boost easy stock and that’s without any billet upgrades (which is an option for the 278 turbos). I’ve heard of people getting turbos in bad condition and sending them to VRP idk how true that is. Send me those settings over I’ll log a couple. I did a rally this morning and there wasn’t anything there I couldn’t keep up with a C8 may or may not have gotten gapped.

Different strokes for different folks! I’ve had a couple CL 63’s I never tuned and now I have a non amg that is! Both of were great, I would caution you to be humble though I know a few M278’s that would smoke some of the newer AMGs. There’s no replacement for displacement.

When this is still true, new technology allows for the compensation.
Sure my 7.3l Powerstroke could pull a house on idle, but going from 3l MB diesels to 2.1l MB diesel, nice surprise is that with bi-turbo the turbo lag is almost non-existent and 2.1 offers more HP, than 15 years older 3l.
The main point that emission modifications are illegal in USA and probably in whole World, even where they don't smog the cars.

I don't agree. I'm perfectly happy with my tuned V6 since these engines appear to have less issues than the V8s while still providing respectable performance. I guess the difference is I understand and appreciate the technology.

Hopefully it will rectified to your satisfaction. Tbh I'm glad I'm a boomer because the ECU tuning bug has never hit me. Good luck and keep the board posted.
