Everything can be rescalled, breakpoints, etc. AMS have full control on the whole calibration ! This is an awesome team, from sales to engineering deparment and their tuning is amazing. I hope they will greatly affect the US BMW Fxx market ! |

So you guys can easily test out e85 then since you have access to all of the tables. I am sure that many would prefer that over running meth or super expensive race gas. Every other direct injected bmw seems to be ready for it... the m3 is outstanding with it. I will look forward to updates!

So now that real tuning is finally available, how much power do you think could be made with those upgraded billet turbos you released last year?

Just thinking about the possibilities here. The s63tu can run over 22psi on pump gas and has large lungs that can pull hard past 7200rpms.. With aftermarket turbos that can supply the load, we are looking at some vicious power with a proper tune

Nice numbers. Can't wait to get this done on my car.

GTRs are in the danger zone at 650wtrq and anything above you're on borrowed time. VERY promising |

A German tuner claims that as of today they can do OBD flash on the Fxx gen cars...

But it's not full OBD.
OBD programming is very easy AFTER bootmode unlock. How it works : Step 1 : PWD extraction Step 2 : Boot mode read, full content of ECU Now you have two options, Option A : Step 3 : ECU patching ( Boot unlock ) for OBD programming Step 4 : OBD programming of the ECU in car. Option B : Step 3 : Boot mode programming. For people that want to know what is inside the patch, it's a simple skip of the routine that is checking the signature of the software. It can seems cool, but in case of OBD programming warranty is voided, 100% sure. That's because of flash counter increasing, etc. We are working on a patch to fix that allready ! |

Hi, this is Martin Musial, president of the AMS performance and the one who has been playing with the M5 on our dyno. I would not call that a speed limiter, that is an aerodynamic/horsepower limit I'ts still pulling in 6th gear very slowly and then you have a huge RPM drop going to 7th gear (looks like it drops to 5100 rpm) and you're in a lower part of the power curve (less power), hence it can't pull any more. Do you know what the limiter was set to in the tune file on that car? Martin |

Also to clear things up, Dynamometers don't read torque at the wheels, they calculate engine torque through HP and engine RPM. 600 ft-lbs of torque at the wheels would make for a very slow car. That 600 ft-lbs get multiplied through the gearing, differential, etc to get to the wheels. Martin Musial |

That's certainly not an aerodynamic/horsepower limit Car was pulling hard to ~320km/h at that time the speedlimiter was slowly pulling back the power and the car stopped at 326. Sometimes the car runs 328, sometimes 322.. We shifted to 7th gear to check if it would matter. The car stayed at 326. If the engine wouldn't have enough power the car would have slowed down in 7th. It didn't. If the limiter would have been gone the would easily do >350km/h. PP-performance showed it with there M6GC with almost the same power. Accoording to Leib the limiters were set to 400km/h Last edited by Erik K.; 01-15-2015 at 09:59 AM.. |

Martin thank you for joining this thread, we're all patiently waiting for final results and turbo results, hopefully it will be sooner than we expect and we will see bigger gains than AMG 63 considering we have more bolt ons available for the s63tu, what do you think in regards to that ? 1. Do you think there's more HP to squeeze out with the set up, or this is where you at ? 2. Will full straight turbo back ktles, mufflerless be significant over the system on the test car ? 3. Do you have to drill in the ecu ? What are the risks we're taking ? 4. Is it possible to integrate methanol as it's convenient for every day. Thanks !

I doubt the addition of a no muffler/straight pipe exhaust system will gain anything measurable with this car. Not to mention it might cause your neighbors to shoot you. The system on this car is pretty free flowing. Again, the turbos at this level are about maxed out so until we upgrade those (which we have available) you are not going to see any large gains regardless of what you do to the car. This system on the car now is a pretty stout setup.
Regarding methanol as was touched on in our other thread we are not big supporters of it. If the system is being used with a 50/50 mix strictly for cooling that is fine as when the system fails (and it will) you are not looking at any severe engine damage. However when using 100% methanol as a supplemental fueling solution you are opening the door to a big "?" in terms of reliability. We have never seen a system not fail and even some of the fail-safe systems have not done what they were supposed to do. Eric Last edited by AMS ALPHA; 01-15-2015 at 10:04 AM.. |
