AA Dyno chart

bimmergoat · 05-20-2008, 04:35 PM

AA XEDE, no other engine mods. Why are these numbers so low? Is this average?

looks like your throttle is closing at ~4700 rpm. Do you have progman v29.2 ?

I don't think so. I bought the car in 11/2007 and have not been in for service.

maybe the operator hit the kickdown button?

Winston Wolf · 05-20-2008, 08:33 PM

Yeah, Something is wrong. You drop dead at 4700, and it should be pulling well past that, then it builds up again. It looks like (if the engine RPM's are read off of the speed of the dyno) it shifted up a gear. Did the operator have it in drive?

Actually, them is good numbers on that Dyno - certainly in with 6L V8 territory.

The only thing that worries me is the massive dip. Either some serious torque management is going on or you are pinging badly.

You should find a Mainline dyno or a DD dyno that can monitor the OBD diagnostics to check timing, boost etc..

Without that information, all I can say is the mid-range 4-6K sux dogs balls....

Remembner that a retarder dyno will always meter lower than a freewheeling roller. I prefer this because it portrays realistic expectations and numbers.

I prefer faster cars at the track that read low on dynos than dyno queens that get flogged.

whatsup with the huge dip? never seen that before

bimmergoat · 05-21-2008, 08:54 AM

Could this possibly be a fuel pump problem? Even before the XEDE was installed the car would sputter at WOT.

installing mods on a car that already had problems is a bad idea... how would you then diagnose the problem? take the xede off and any other mods you might have on the car.. bring it to BMW and get it running right.. then start moddidng it.
