To be honest we still have a bit of snow on a ground, and most roads are cracked. I'll try to find a good area to test my car 0-60, not sure if I'll be able to find something for 60-130

In fact you cannot get a good number if the DSC is ON because it cuts the engine and applies brake due to too much power and torque release at hard acceleration. Turning the DSC off and using launch control is so dangerous in the area you live. DON'T DO IT PLEASE. I highly recommend you to wait until the weather getting better and test it with MDM first in a wide area and nobody around! |

Your engine makes 475lbs.ft at 4600rpm. The stock engine in post #21 makes a nice and steady 500lbs.ft from 3k to 5k and then gradually drops to 400lbs.ft at 7300rpm http://www.6post.com/forums/showpost...5&postcount=21 A Manhart M5 on the dyno here: http://f10.m5post.com/forums/showthread.php?t=830347 It has 650ft.lbs at 3k and drops slightly to 630ft.lbs at 5k and falls gradually to 460ft.lbs at 7200rpm. In the midrange the Manhart makes a whopping 150-175lb.ft MORE than you do (35% more)... Your engine even makes less torque than a stock engine (although comparing results from different dynos doesn't provide a definite answer on this). Anyway, the shape of your torque curve is not right for the S63 engine... Here is how the dyno graph is on a BMS Stage 1 M5 (and how it is supposed to be...): http://www.n54tech.com/forums/showthread.php?t=22393 Please listen to gmd2003 and others that have pointed out a possible knock situation. Something really isn't right in the midrange there... Don't risk your engine!!! Last edited by Boss330; 03-12-2014 at 04:10 AM.. |

http://preisliste.ac-schnitzer.de/ac.../121410710.pdf http://preisliste.ac-schnitzer.de/ac...10&ID_NR=11548 Not sure what the BMS does? Only boost manipulation? EDIT: The BMS connects ONLY to the TMAP sensors and has no control over other sensors/circuits (unlike the ACS piggyback). I would be extremely cautious running more boost on a tune that does NOT control timing and fuelling at all. Keep in mind that the ECU still believes it runs stock boost as well... (the whole point of the piggyback is to manipulate signals to and from the ECU so that the ECU still reads 17Psi even though it has 20Psi boost). http://www.burgertuning.com/instruct...e1_install.pdf Last edited by Boss330; 03-12-2014 at 06:50 AM.. |

That dyno graph looks more like the BMS dyno graph I also posted. It has a much more consistent torque curve and shows a consistent increase in power over stock due to a slight boost increase and high octane.
Your dyno graph was "all over the place". Either the dyno operator did something wrong, or the ECU was correcting for knock or some other fault it detected. I would suspect the latter explanation as the ECU also shut off at 6000rpm (if it hadn't done so, you might have ended up with a blown engine...). Did the dyno operator datalog via the OBD port and measure AFR via exhaust etc? |

I really wanna try Dynojet. Also, lowered my PSI to 2.5

I would turn that boost down. That curve looks messed up. You only made 10 more HP than me but all through the middle of your curve I made much more hp and torque than you. As you know my car is basically stock with all you have on there should be way more than 10hp more I would think. Be careful

Did you do the runs in 5th gear? Then you hit the 155Mph limiter at around 6000rpm...
And according to a thread on the M5 forum, +3 PSI setting on the BMS in reality equals +4 PSI on the S63 due to different TMAP sensors on the S63 compared to the N63 that the BMS was developed for... So if you were told it's ok to add 3PSI of boost that isn't the same as choosing +3 on the BMS interface!!! |
