Speed Density tuning an EVO8 w/dyno sheets
What we can say is that ProjectWhite weighs considerably less than RyuEvoIX and this is a considerable factor when it comes to E.T. and MPH performance as someone mentioned.
We are glad that Dave has worked with MD to get his rpm roll speed calibration corrected and we do understand the frustration cal changes make to all prior data which is why we will never change our calibration as it will negate all prior tests and prior customer files for comparison purposes.
We use a weather station for SAE J1349 and Buschur does not. It is a personal decision that each company has decided to make and there is no right or wrong way to do it.
From the sounds of it, it appears that the customer is happy with the performance with a fun car to drive, primarily in road racing. The way I see it, is that there will be a new FPRed Evo terrorizing a track near you, courtesy of BR.
All the best!

I wont discuss the dyno any further as per mod request.. However I have spoken with RYU and i am confident Project white is heavier than his car..

Anxious to try a speed density setup on an 04 RS. Currently running E85 on a IX turbo. Been sort of maxed out at the power its making now. Want to do a real back to back test on the same day this winter so I can post up mass air versus SD results for my setup. My MD dyno has WCF too. But in the winter I prefer to only look at the actual numbers but I do use the weather station to tell me if my test day is as close as possible to the previous test day. So it does have some use. I always want my own test results to be as camparitive as possible without many outside variables. Also as far was calibration of the dyno. I also leave it alone. No major variable changes. Although it doesn't hurt to check the calibration atleast once a year. MD suggests more often than that. Its like anything else mechanical, it won't remain static forever.

When it all boils down to it, even similar model MD's have older or newer firmware and software revisions, there are 3, 4 and 5 roller units in production with different roll weights (more for additional rollers) and even two exact models with the same amount of rollers may differ.
In the end if the customer is happy, and the performance is consistent at the track, there are before and after numbers in most cases as a yardstick to support the gains, then that is what matters.
If the project white car is heavier than I thought, I apologize for the mistake Dave.
Back on topic, good job DB. Looks like you've caught right back up with the stock ecu advancements in absolutely no time.

I understand the difference with the WCF. Most turbo people also understand that winter weather is best. We don't exactly test stuff when its 115 out here and get all excited with the results. But when its below 50 degrees and the weather station shows close to 1.0 I try to do all my testing then. Not like we will ever see a correction factor of less than one. I like the actual numbers that are produced. All other factors being equal, your MD dyno is calibrated with MDs setup computer. Doesn't matter if its a Euro or early MD500 with more rollers. i.e. an EVO X should make the same number on the same day on all of the MD500 models if there were setup for back to back to back testing. And yes from unit to unit, same model the roller weights are different. To balance the rollers requires weights a wee bit bigger than wheel weights. You see how they balance them at the factory?
When I do the speed density test and comparison. Will be all on the same winter day where the weather won't change more than 5 degrees from mid day till late night. Regardless of the numbers most of all just want the graphs to overlay. Looking for averages, not peaks.
One positive note out here is even though the temps change fairly drastically from summer to winter. Cars don't require drastic retuning to compensate.

The table is under ISCV stuff rather than the Idle section. Here's a screenshot. Is this the table that you are talking about?
