How to Tune a Mercedes V8. Get the most from a M176, M177, M178, M278, M157

[@zacki5663]

man i swear u could make a whole channel of just this. only thing else out there is russian forums and websites

[@TunedMercedes]

yes and ive got a lot on my website too tunedmercedes.com

Great video. I just picked up my M278 last month with 38,000 miles. First time owning a Twin turbo v8 and I have some interest in modding and tuning but I don’t want to go crazy and mess up my car right off the bat of course. Im learning more and more everyday

[@TunedMercedes]

Nice. You may want to try turning off the ESP. It's is a nice way to tap into some extra power without tuning.

[@c.a.n.4202]

@@TunedMercedes Is this done simply through the dash menu?

[@TunedMercedes]

@@c.a.n.4202 yeah man go to drive assist, down to esp -> esp off. can be changed on the fly. raises torque limits quite a bit (not all of them but some of them surely). cruise control will not work with ESP off. but I believe that is the only drawback.

[@c.a.n.4202]

@@TunedMercedes can't believe I've had mine this long and did not know this! Was planning an ECU tune in the new year but still definitely be trying this asap.

[@richardjackson4559]

@@c.a.n.4202 Do it. My friend got a stage 2 on his CLS550. The difference is tremendous. Becomes a complete different car. ECU also removes your speed limit. He got it up 157mph with ease the other day.

[@LeTigre22]

You guys are crazy, these cars are already so fast and have more power than we need. Longevity at stock power is more important

[@Zeekdoc]

You get a hell of alot better gas mileage like 15% that’s worth it alone

[@TunedMercedes]

i think they will break anyway around the same time and some things like adding cooling and disabling the low pressure mode will help it live longer

[@stevep8525]

Awesome info, really want the TCU tune, downpipes and look into the methanol.

I can help when you're ready

So an M278 (‘14 S550) can handle 600WHP fine, but I’ve heard throwing 600 at the trans, even with TCU Tune, you’re likely to destroy it.

[@TunedMercedes]

The transmission can likely handle 850-900 whp without upgrades. In fact MB used this transmission for years on the 65 and 600 engines. TCU tune helps a lot man, I'd almost recommend doing it before ECU. It's at least as much of an impact on performance imho. ECU is better when rolling, TCU can be felt more from a dig.

[@Nate_tureboy]

I thought you'd hit on long tubes and larger tb's. I have an M113k which like the headers and the e55 05 06 tb/SC snout upgrade (if you have an S55) But I'm looking to mod my '14 GL63 AMG so was interested in the suggestions on headers and tb (if they exist even!)

[@TunedMercedes]

I hear u man and it is solid idea for SC. this video really about turbo MB. I'm better with turbo Benzes. I have done a few NA to SC 6.3 tuning which is interesting.

[@aliislam580]

Hey, is it too late to start modding a M278 with about 100k miles on it? Or if I can are there any preventative maintenance steps I should take first?

[@TunedMercedes]

I'd bring it to a tuner to run through. There are some guys who are tuned around that milage. Someone like Morendi can do a remote tune with and log some data to make sure the tune is running well for you.

[@Dying_Breed.300]

I have a 2013 cls550 and about to put downpipes on it . I have stage 1 tune but I’m not sure if it’s at the optimal tune. What’s the best tune for stage 2

[@TunedMercedes]

I really like my m278 tunes since I spent so long getting them good. I can get you my stage 2 tune for $1200 USD. I can also get you a TCU tune for the same price -- feel free to text or call me at 202-770-8010

[@TheT1r1]

I am thinking about running the VRPspeed risers (cheaper than UPD) with weistec dry filters. What do you think? I don’t want to mess it up like you said with the BMC filters getting sucked in. What’s your thoughts.

[@benzgarage2599]

Don't do it, not worth it. Either buy the blackboost system or leave it as is.

[@TheT1r1]

@@benzgarage2599 why is that?

[@TheT1r1]

@@benzgarage2599 not looking to spend $1500+ on an intake system. I’m looking at performance filters. Thinking about weistec

[@TunedMercedes]

@@TheT1r1 ​@UCmT-4ZSvBhxZLNf28WrXoyA Black boost will give you more power than the risers plus filters. But there is some power to be gained with taking out the huge MB filters and lifting them out of the way of the intake. I can understand the thought of just going to the best, but I think risers plus performance filters do make a pretty big impact. I'm not sure anyone on the MBworld list of fastest m157s are using stock air filters. Some do use risers. I've heard people have made their own. Some on Facebook.com/tunedmercedes like Tyler have run their own 65 amp scorpion style intakes, which DTK used, and those are likely even better than the black boost in terms of pure air intake and power creation.

[@JuanEspinoza-vd1nx]

Hi, great video! I was wondering if I use HP tuners and unlock my ecu. I am unable to flash my car with my genius? Like if I were to get a tune form weistec or eurocharge.

[@TunedMercedes]

that is correct but I could at $399. feel free to text/call/whatsapp [phone]

also i should no issue going back and forth between open port 2.0 tune and hptuners

[@keithyuen2005]

Great video! Would you say the M157 or the M177 is the definitive AMG twin turbo V8 if both are stock?

[@TunedMercedes]

I would have said the m157, especially later ones with the updated timing chain. But Eugene from Morendi mentions that he actually thinks the m177 is the better engine and smarter upgrade for those currently with m278. He basically said you can make a lot of power with m278 and m157 the issue is keeping it reliable.

[@austingtir]

M177 is hands down the better engine. M157 have bent rods from the factory which is just one of the root causes of manyof their issues. 2015 up (not sure on the date they changed the bore material) M278 are the only version of the external V turbo biturbo engine thats really worth buying imho as they never changed the bore material on the m157 or fixed the bent rod issue. The early m157 and 278 (pre late 2013) are almost complete junk until you do timing chains, tensioners and check valves. late 2013 up are better but still have major issues. M177 has issues too but nothing as ridiculous as sheer amount of stuff wrong with m157/m278 Tuning a m157 is literally playing russian roulette imo. The 278 is a little better in some instances because of longer piston skit (still has the same bent rods) but it doesnt tend to manifest bent rods and the bore scoring as much because of the longer piston skirt and smaller bore (and less people tune m278 than m157). If you pull your 278 or 157 down and fix all the issues including checking and putting straight rods in it they are then great engines that should be pretty reliable.

about 600 hp is max with stock turbos and fueling

[@TunedMercedes]

tcu tunes are pretty well guarded, even the maps can be hard to get.

[@whatsupwithsteve]

Nope, not gunna mess with my GLE 63s. I built the daylights out of my c6z06 which was probably perfectly balanced at the stock 505hp and it was not nearly as fun or reliable after the mechanical mods and tune. I was held hostage by tuners and mechanics that didn't seem to care as much about my car once they got all the cash for 'fixing" it up.

[@TunedMercedes]

I get what you are saying but MB has a long history of being tuned Carlsson, Brabus, Renntech, AMG, and a great platform for a tuner car. Some cars are better left alone. MB is not one of them. It's a canvas to make arguably the best cars in the world.

[@whatsupwithsteve]

@@TunedMercedes Ha yep and I get that! It's just that unless you know how to tune yourself you are held hostage to the guy/company that tuned your car. Plus at least in Chevy's case should you need a repair the dealer won't touch your car. That can put you in a real bind! But I agree, power is addictive and the quest for more is hard to resist..:)

[@TunedMercedes]

@@whatsupwithsteve we use hptuners and keep our tunes unlocked so you or a different tuner can make edits if you use an mpvi device. RTD is locked to one tuner.

[@whatsupwithsteve]

@@TunedMercedesso can you reset to stock and the dealer can’t find out? In case you needed service?

Yessir you can flash your car back to stock with your phone in many cases. If you flash your car more than a dozen times they may flag it.
