    • AMS Performance releases 2014+ E63 AMG and E63 AMG S 4Matic ECU tuning - $2995.95 and gains of 100+ horsepower

      AMS Performance released their ECU tuning for the updated E63 AMG. The new 4Matic all wheel drive E63 AMG's come with more aggressive software from the factory and it shows with Mercedes underrating the car. The stock output at the crank as measured by AMS shows 619 horsepower for the E63 AMG S and 598 horsepower for the standard E63 AMG. That certainly explains why the 4600+ pound E63 AMG S is able to run roughly 122 mile per hour trap speeds in the 1/4 mile.


      Despite the more aggressive tuning from AMG there is still plenty of power and torque left on the table. There are torque limits built into the ECU by AMG in order to protect the 4Matic drivetrain that have stumped tuners but AMS seems to have found their way around these limits. The result is an increase in horsepower to 700 at the crank and 830 pound-feet of torque for the E63 AMG S and standard E63.

      Both cars hit the same tuned figures as they should showing the differences in the models are artificially limited by software. The only reason to get the AMG S is if one is interested in preserving their warranty and not tuning the car. If you're reading this site that is not you so buy the standard E63 AMG and pocket the change.

      The difference in horsepower between the 2014 E63 AMG 4Matic and E63 AMG S 4Matic is 21 horsepower. Not much, right? Well, the torque figure is where the difference really lies as the S has an additional whopping 89 lb-ft of torque. There is a big difference in the mapping of both cars so Mercedes is not lying about the advantage of the S model.

      Pricing is $2995.95 and certainly worth every penny. AMS product page: http://tuning.alphaperformance.com/p...matic-biturbo/

        Good work guys. Any chance on getting those wheel numbers? What type of dyno is this? Dyno Dynamics?

        That would decide it for me. I'd opt for the E63 AMG 4Matic.

        Here are the dyno charts of our own 2014 E63 (Non S)

        Our apologies for no torque readings. We were having a hard time getting a tach signal on the dyno.

        Here is a 2nd - 5th gear pull on the dyno

        Here is a dyno from a S model we did a tune on followed by some comments from the owner of the car:

        Got my car tuned, by the best in biz.

        Car is a beast

        541 awhp/579 awtq pre tune

        603 awhp/717 awtq post tune

        This was done on an AWD dyno so comparing numbers to the earlier RWD models/my '13......these numbers are pretty damn good! Alpha/AMS have this same tune in their shop 2014 E63 and its been running like a champ.

        This is gold. Thank you.

        541 all wheel horsepower stock.

        Dynojet numbers too, absolutely perfect.

        It looks like right now the RS7 is putting down more to the wheels tune only.

        Damn. That's very nice. Makes a basic E63 seem like a very tempting proposition.

        To be fair though, are there not suspension/chassis changes with the "S" package? Can't remember.

        Perhaps, I don't know. The engine is clearly just software though.

        Most definitely. Trying to see if I can find info about other "S" package enhancements but no luck yet.

        I do know that if you care about that sort of thing, you cannot order ceramic brakes on a non-S, nor carbon interior trim. Both are silly limitations. I guess I wish they would have kept it as the Performance package, seems much less contrived. Either way, the AMS tune seems to be the way to go here.

        They probably force those restrictions to make the S more attractive. It makes the standard E63 more attractive to me though.

        I bet too if you asked really nicely they could order the ceramic brakes on a non S car. Or not too nicely. I would like that if I was buying.

        I'm sure there is a way to do it. It's not like they won't fit.
