• 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/

      Dyno charts below. BenzBoost hopes AMS can show us charts with output at the wheels in addition to these crank numbers:

        My 2014 E63 S 4 matic what i would be aprox when it is tuned. What you see is from a car without 4wd.

        Right but the 4wd and 2wd will have different numbers and require different tuning.

        RWD Cars make more power, also what type of dyno is that? what does a stock car make on that dyno? too many details left out.

        The torque management is still very much alive in our tune. We have just found a way to keep the car AND driver happy Click here to enlarge

        It will still be aprox the same numbers.

        At the crank, sure, but 2wd and 4wd will have different losses.

        We are talking about hp and not whp, so yea crank. Thats normal in EU.
        Thats why we need more power. The 4 matic have more drivetrain loss and more kg to move around with. Click here to enlarge

        That's why I prefer wheel horsepower figures to show what the car is putting down to the ground as it can vary quite a bit.

        Power and torque are not going to be a problem with tuned M157's. Looking forward to the turbo upgraded 4Matic's.

        The car is a turbo upgraded 4 matic.
        As long you are comparing whp with whp or crank with crank you get the same picture from the same car. If the loss is 125 or 140 hp is not so important. But the times say a lot more about performance.
        I hope you can se what i am trying to say with mu bad english.

        if the same model of car have 600 whp with one tune and 650 hp with another tune.
        the crank hp also have a difference about 50 hp.

        No you don't, that is the reason we have dyno's and why we talk about wheel horsepower.

        It's very important. It's why an M3 is faster than RS5 despite the RS5 having more crank HP supposedly.

        You can compare a M3 with another M3 on crank hp, but not a M3 with a C63. I know that
        So you did not understand it :-)

        No I understood it but considering say an M3 has two different transmission options, different wheels, weather, elevation, etc., the crank rating isn't a precise way of comparison.

        Wheel horsepower pretty much always is preferred. That's why we dyno.

        if you take the total same car model, and put in on the same dyno with the same wheels the same day, it dosent matter if it is wheel power or crank power you compare from the same car to car.
        if it is whp og chp you compare, you will get af different result on different dyno, and the temperature, the airpressure and water i the air % will all give different results.

        on page 1 there is a diff between whp and chp that looks pretty low for a 4wd car with aut gearbox. ? I think.

        The best way is anyway to put them head to head on the road. Then it is real life.
        there is also a diff on dyne due to cooling of the engine and if there is Co2 in the air if the ventilation in the room is not good. We can keep on write things that have effect on the resoult.
        and i have never said that whp is not good.

        Why doesn't it matter? How do you know the drivetrain losses without ever getting a dyno in the first place?

        I mean I really don't see the point here. We dyno for a reason.

        The best way is to have the most data available from all sources.

        I try a last time.
        if you take the e63 2014 amg S4matic
        if you have crank at standard car at 619 hp and tuned at 700 hp, there is a diff at 81 hp. 12%
        if you have whp at standard 541 whp and tuned 603 whp, there is a diff at 62 hp. 11%
        Is it then not the same 11-12% more power you get with the tune.
        here on page 1 it maybe is not the same car,
        but it is the 11-12% i an trying to explane to you.

        Drivetrain losses are not standard across dynos. Drivetrain loss also is not static.

        Going by crank HP is not precise. I understand your point but it's just better to get a dyno than to estimate and it gives a better picture of what is going on especially through the entire curve which a peak crank hp figure does not provide.

        Then there is another thing.
        should the drivtrain loss not always be the same hp/nm , lets say 75 hp, if the car have 500 hp or 700 hp. And not counted in % ? As you normaly do in US test video.
