    • 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/

        I mean that loss is closer to static than % loss.

        Lets take whp on the dyno.
        if a standard car have 500 whp and we know that it have 600 hp power on the crank, then it have loss at 100 hp or 20 %.
        if the car is tuned to 650 whp, then
        will it have 650+100 hp, 750 hp on crank or
        will it have 650+20%, 780 hp on the crank ?? You meen.

        I think you're trying to make a point that if you know the losses on a certain dyno you can work with the % from the crank figure not needing the wheel figures.

        What I'm trying to tell you is losses change based on the size and weight of the wheels tires, fuel, elevation, rpm, etc. There are a ton of factors.

        Plus, a peak figure only tells you so much. So we know a car makes 600 hp at the crank and 500 whp, so what? What does it make at 1500, 2500, 3500, 4500, etc., rpm? You need a dyno.

        I'm not really sure what we are discussing at this point but I mean dyno's are necessary, important, valid, and offer more data thank a crank rating ever can.

        If a car have 600 hp on crank and 500 hp on dyno, will the loss always be 100 hp what ever hp it have.
        this is a theoretical example.
        Maybe you dont care, but then you have to gues like in the video here if the car have the hp that the factory claims.

        And still, i dont say that crank hp is better, but what is the best way to calculate between whp and crank hp.

        I disagree with you and that's fine.

I know you guys made a thread last year about carbon fiber airboxes and a bunch of other parts any update on that?
        Alright yeah I thought so but I wasn't sure and didn't want to say something that wasn't true. Thanks for the info.

        The carbon airbox is very close to complete, along with the turbine outlet pipes, down pipes and a few other things that will be announced soon Click here to enlarge

        This is really good stuff guys...

        Also @ALPHA Performance I'm close on getting nissanboost.com up. I really wouldn't mind if you started sending me some GTR info: http://www.nissanboost.com/content.p...ce-engine-porn
