Here are some graphs from neovb's dyno session.
This is in fourth gear, at 100% and 0% settings. 100% and 0% settings, fifth gear. 100% settings, fourth gear compared to fifth gear. Note that we use SAE correction, which is going to read a little lower than the STD correction I often see around this forum. Quote:

But if the car will see high load conditions on the road (and it will) I do like to get some readings from the higher gear. --Dan Mach V |

Those charts look great! It would have been nice to do a run with the JBD removed for a stock baseline. The min setting adds 15-20hp I believe.

267 sounds too much WHP for stock. That would be close to 310-320 crank, which is far more than BMW quote.

Dyno's are kinda useless for relying on their PEAK numbers. Every dyno-be it the same make and model-will read differently(Dynojets usually read the highest of all the brands, and it can be as much as 20% or more). For that reason, you need to pick one, and stay with it. Their uses are many, but for power cataloging, you pretty much want to baseline the car stock, then run it again after each mod, so you can see if you gained or lost, and how much and where(PEAK isn't all that...bottom end and MID-especially on a track, is very important). Despite the peak numbers varying wildly, changes-gains or losses, are valid numbers.
Since you're using the dynojet, you need to keep this in mind, ESPECIALLY if the shop just installed a mod of some sort, and is gonna show you it's improvement. You'll see at the top of your dyno sheet the word 'Smoothing', and it's setting can be anywhere between 1 and 5. What it is basically is how 'smooth' the plot lines are. A shady tech will set it at 1, because the plot(s) will be so erratic that it'll actually show an additional bogus hp or two. You WANT your smoothing to ALWAYS be set at 5. If you see the number change(down to 1 or 2 specifically), get your money back and go somewhere else. |

5 is the max(on DJ's anyway), so if that's what you have, then you're good to go. Just make sure it's always set there in the future.

For baseline dyno sessions, we offer to give our customers the raw dyno data, and the Dynojet software (WinPep) is free to download, so you can take the dyno data home with you and make your own graphs, setting the smoothing and correction factors however you want... --Dan Mach V |

Where did you guys get the rpm signal from? I was supposed to go on a dyno jet yesterday but we couldn't find a signal. We tried the injectors too.

Since you are planning to get the Evolve tune through VS, I would expect Paul@Evolve would be willing to help you with the info - especially since he has a 335d DD that is going to be the guinea pig for their development work.

I really don't know how to read dyno charts. Does this mean the car is hitting max rear wheel torque of 463 ft lbs in fifth gear at approx. 2,250 rpms and max torque in fourth gear at approx. 2,500 rpms? If this is the case, will it make that kind of rwt at any point in first, second or third gear and if so what rpms?
