Glad someone understands E-moticon-glish… jeez, people! // damn those McLarens

That's understandable but, for me, the tune requires additional positive-attributes beyond merely some hero-run 1/4 mile time--the car still needs to be drivable and usable and comfortable... and trackable, too

I'm attending a runway event in about 2 weeks: unprep'd 1/4 digs and roll-racing--we'll see what we see.

So, that said: I've no track data yet--only Dragy thus far. Per my earlier posts and per the Dragy leaderboard (the credibility of the Dragy now assumed "plausible" at the least I hope), I've got a repeatable 0-60mph in the 2.8s--2.9s range with a standing 1/8 mile at 6.92s. Getting 1/4 mile times here in WA is tough short of obtaining track data--risk vs. reward and all that. The only 1/4 mile run I have isn't representative: horrible spin on launch, undulating surface and I was forced to brake early due to a somewhat important lack of remaining road. Even so and my excuses aside, I've a 10.90s 1/4 mile time (also uploaded to the Dragy leaderboard)... but I'm convinced this is a 10.5 or better car if I take my butt-dyno and the optimal 0-60 (unprep'd), the 1/8 mile (unprep'd) and a 60ft of 1.73's (unprep'd) into account--combine that with the crappy 92oct pump gas and my dreams of glory are yada yada yada. Granted, the predictions are all math... but even a 10.9s on well-prep'd tracks in a family sedan on pump-gas is impressive.

Time to pump in some MS109 then. But be careful though, it the torque limiters were not adjusted accordingly, you might hit them with race fuel. Best to give EC a call and ask them if you are good to go. Dragy reads 0.1 sec slower than the track slip. And traps are always like 2mph slower on dragy. So expect the traps to be higher. But for some weird reason, these cars launch way better on road tarmac than the strip. So 60ft would most probably be worse at the track. My best 0-60 times were always on normal roads. And round 0.2sec slower on track.

You must have one VP distributor around you. Also I am sure you know, DO NOT use Octane Boosters like Boostane! Go proper race gas or just run pump gas. 92 sounds a bit low for running that thing at the track. Unless its undiluted 92 and does not have 10% ethanol.

I would do more research first as your supposition is not reality. Most current tunes are bring 80/80 awhp awtq if not more....thats at the wheel.

limeypride

Let me guess, you haven't tried one with a tune, right?

limeypride

Thanks. I've already spoken with Jerry--all good on that front.

We tried I think 4 Dragys and compared to the track slips--they weren't consistent with one another or the track but they hovered well within 0.1s on timed measurements and 1-2mph on speed.

All my numbers are on 92oct pump with 10% ethanol (as stated on the pump at least). Since this event is at an airstrip, it's unlikely to have any unleaded race fuel and to say that gas stations here selling race gas are few and far between is a huge understatement. So, 92 at the track it is unless someone else brings some and are willing to sell/share.

You can order MS109 online I think. I would suggest running atleast 40L for the ECU to adapt.

This has been an interesting read. I live in Central Texas and am lucky to have a Mercedes dealer in Georgetown that works with Renntech AND a Eurocharged shop in Round Rock.

I am looking at tuning for an 08 E63 so non of the turbo fun but I want to stop by Eurocharged soon and see what they can offer. I am loving this car but a little extra kick in the pants would be perfect. Also, it is impossible for me to keep any car I own stock.

I'm not sure if it's worth tuning a non-turbo MB. The last time I spent money tuning a naturally aspirated car turned out to be very disappointing. I then added a supercharger which cost a lot but made me happy. Maybe a few inexpensive mods (CAI etc) and a Dyno tune are the best route for your car..

Chief36

I think Eurocharged has a dyno at their shop here in town. Thanks for the advice. Hope to get by and talk to them soon. I know they offer a tune but not sure if it is all done on the dyno.

I was curious, so I just took a look at some options for your 2008. IMO before you consider spending a few thousand dollars to gain 20-30hp, you might want to consider trading-in your 2008 for a 2012 with the bi-turbo engine. If this option is feasible and of course if you're interested, then an ECU tune would make a huge difference on a 2012+.

There are plenty of 2012-2013 E63 for $35k-$40k. I noticed a beautiful Silver 2013 with 53,000 miles for $37,500. That's a great deal and with a simple ECU tune, you'll be about as fast as a stock 2018 E63. Actually, there's a 1 owner 2014 (1st year with AWD) high mileage for $39,500.

Chief36

The numbers I have seen on the turbo E63's have been insane.

I looked at a 2012 local that had more miles than this 08 but I just love the look of these 07/08/early 09 E63's. That is what drew me to the car when it came out along with the big V8 of course

Someone else mentioned doing long tubes. Those could be an option but not sure yet. It would go well with a tune to open up the exhaust but still contemplating how I want this car to sound. Spent an hour on a meeting listening to YouTube sound clips. Need to hit up Cars & Coffee next month to listen to other AMG's around Austin in person.

Tune for tune I would expect them to be closely matched on a roll race. The W213 launches much better so will kill the W212 from a dig

Andrew-NY

Yes, you're right, I meant from like 50-100. Tune for tune ? Or do you mean W212 tuned and W213 stock ?

Andrew-NY

Fair enough but the interior looks much improved in the W212 and you can gain 150hp/200tq from a simple ECU tune. If you're like I was 10 years ago, you'll end up dumping a bunch of money on the 2008 for long tubes, CAI, dyno tune etc and you'll still want more. Unfortunately, it takes quite a bit more than 30hp to really feel it and there's not much else you can 'sensibly' do to a naturally aspirated MB. That being said, it sounds like you just recently purchased your '08 so enjoy it for now and then see what happens.

Chief36

Cheers and thanks for the thoughts. I really do appreciate it, honestly. This is my 1st AMG so learning but I went with my heart first. I have been a huge fan of 4 door beast for a long time, just sold my 2006 SRT8 Magnum. I started on the SHO's back in mid/late 90's which were a blast. I think a 2012+ is in the future but not yet.

I was looking at DME Tune for my e63s and the numbers it's putting down looks good. Has anyone went with them and if so do you recommend going with them?
