I dont disagree with you about that, looks like one to me also.
But this car is tuned to 19psi tapering to 15psi and is relative safe tune as I didnt push timing so I would highly doubt this car would make this power level on true reading mustang.

Edit:confirmed it was dynojet corrects used

The Virtual Dyno plot is on the Dynojet setting. It says right at the top.
The actual dyno plot is from a Mustang. That is how all Mustang printouts look.

Wow! Great test! That change would put my Virtual Dyno numbers nearly spot on with my actual Dynojet numbers! I guess the official recommendation will just have to be to turn off fast polling for all Virtual Dyno logs.

BTW, do you really trap 129mph and only make 400WHP on Virtual Dyno. That doesn't seem right. I'd guess you would have to be well over 500HP on Virtual Dyno for that trap speed.

Can someone please tell me what version of RR started having the two types of polling? I cant find the option in my settings menu.

TIA

I dont use rom raider. I use a program called ECU edit. there is a check box is you want to use fast polling

no 129 was around 475 WHP on E85. The test I did was my pump gas tune at 21.5 psi that a low to mid 120 trap
These were done one the VD setting as well

RR fast polling causes weird numbers for HP and TQ. They both get put through the same logic to create the HP and TQ numbers so there has to be something different in how they are logged. Ive noticed some really big spikes and time and RPM not correlating in fast polling logs. Id hold off on trusting fast polling when tuning and using Virtual Dyno. It just seems flaky to me.

renosuby just showed that ECU Edit fast polling does the same thing.

I have also notice that the "Smooth Time & RPM" option in VD affect the numbers. Having it unclicked makes the numbers higher.

Its due to that option smoothing time and rpm prior to power calculation. Ant smoothing lowers peak power but gets rid of error. So you have to balance it like on a real dyno. Spikes are anomalies and you can usually tell by looking at a graph if more smoothing is needed or there is some abnormal spike

I want to use VD for pre vs post upgrades comparisons, what smoothing factors / parameters should I select?

For your comparison make sure to use non fast polling as power level isn't correct on fast polling.

When using smoothing start from 1 ( 0 is always to wavey) and keep increasing smoothing until the humps get smaller. You don't want to over smooth as it will alter shape of graph to much. Dyno should have some small curves or ripples to it unless it just really smooth pull.

When using non fast polling I typically use 3-4 smoothing but it just depends on the humps in graph.

I'm not sure I use openecu/romraider but I'm sure someone will answer you.

can't get this software to work, no matter what I've tried.

Manually gone through the .xml file, added my log parameters to the appropriate columns etc. (RomRaider logs)

Keep on getting "No wide open TPS data found", even though my TPS log shows over 100.

or:

E111 Column 'Throttle Plate Opening Angle (4-byte)* (%)' does not belong to the table 3rdgearlog.csv.

And E106: Imput string was not in a correct format.

even though it does....

Any ideas on how to get this to work.

So I swapped wheels on my car and now my graph looks totally different?

No other adjustments to the car other than the wheels...

Anybody else ever had this it just a fluke thing

are your tires a different size? Are the wheels lighter? Was the second test run under the same environmental conditions as the first? Did you set the ambient temp and tire size correctly for the graphing?
