Excellent, be sure to get some 60-130mph numbers if possible, it will be nice real world data , which I much prefer over dyno numbers . 60-130 is a great indicator of how fast a car is bc it takes traction out of the picture . Just make sure the slope is as little as possible (flat) and def less than 3% Have fun !

Can't wait to see the real numbers! Just make sure to test in a wide area for 0-60 and PLEASE DO NOT TURN OFF DSC!

What about MDM?
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

I know that horrible weather (I used to live over there for 5 years) and that's why I asked you not to turn off DSC.
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!

Bc Manhart has a tune to allow more fueling and less timing to go along with the higher boost . The BMS is essentially just the Manhart boost control unit for a lot less money . Crude but effective to a point . The OP will end up making ~ 630 whp on 94 octane when he turns his boost back down to 2.5 psi . The extra 30 whp is not worth what Manhart is charging for almost the same tech with a dev file .

To get an exact number, I'll have to bring it to AWD dyno... Estimate is 650WHP.

Yes the traction control was off.
I am using 94 octane.

Charts: (1tun with pedalbox off, 2 runs with pedalbox on)




Looking at your graphs it really seems to have serious issues in the midrange especially...

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!!!

Which I believe ACS also has via their piggyback. It connects to the ECU connectors on each ECU and intercepts several sensors and circuits. I know they do ignition and fuelling mapping on other models via their piggyback.

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).

I'll try dynojet soon...
Here's BMS dyno with a high octane

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?

To be honest I don't even know this dyno, it's different from others, I think they remove rims before starting the process.
I really wanna try Dynojet.
Also, lowered my PSI to 2.5

Then it's a Dynapack. One of the key advantages is that you eliminate wheel slip as the dyno attaches to the wheel hub. But it can't measure transmission losses, the operator can use a factor to calculate crank hp though.

http://www.dynapack.com/

This shows some of the pitfalls with improper use of a Dynapack and how numbers can be manipulated (not saying any of that happened with you, just posting it as infomation):

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!!!

Yup 5th gear, might be the limiter. Definitely need to do more tests to find the perfect PSI level.

To be honest man, don't get it for m6, your pedal will become WAY too sensitive, very hard to drive with the pedalbox on. It was fun on 750i, as it had a less sensitive pedal...
Pedalbox is something like spring booster.
