Virtual Dyno Software
One of my friends on the forums posted this and I thought it was really cool and pretty spot on. I need to get some logs of my car now and see how this thing works. its pretty cool.
Link from forum: Virtual Dyno Software - pretty damn cool!
So I dont know exactly what program I would need to use with my trifecta tune to log it and make it compatible with this software. It does have a lot of different types. HPtuners works anyone one know what trifecta software is?

Supports the Cobb and JB4 logs so far...i googled the specs for the 2008 E90 335i 6 speed manual and provided them over to Brad (creator of Virtual Dyno)..he turned it around VERY fast, adding the car's profile into the software and supporting the logs out of Cobb and JB4...go ahead and send him your procede or whatever else tune you can log with and he'll add it to his database so you can just do a 3rd gear run, log it, drop the csv into the software and see where the car stands power/torque wise...its pretty damn accurate too and fairly well respected in other online communities already...
I'll be posting a bunch of virtual dynos here in this thread over the next few days running both Cobb and the recently acquired JB4 which I'm using to run more top end boost and progressive meth on RBs while waiting for Cobb's stage 3 release...
You're welcome to post your virtual dynos here as well and maybe we can turn this into a sticky if it turns out well...no results are too low so don't be shy Click here to enlarge
P.S. If you don't see your car in the list of profiles just google the specs on your car and send it to Brad Barnhill at:
bradbarnhill at hotmail dot com
with the following mandatory info on your car (below is an example for my 2008 335i E90 6 speed manual with 275/30/19 rear tires...). You'll need to get the exact numbers (google them) for frontal area, drag coefficient, gear ratios in order for the software to be as correct as possible, estimates aren't good enough:
<CarMake>BMW</CarMake>
<CarModel>E90</CarModel>
<CarSubModel>335i N54</CarSubModel>
<StartYear>2007</StartYear>
<EndYear>2010</EndYear>
<Weight>3549</Weight>
<TransTypeManual>true</TransTypeManual>
<TransGear3>1.582</TransGear3>
<TransGear4>1.192</TransGear4>
<FinalGearRatio>3.08</FinalGearRatio>
<DragCoefficient>0.30</DragCoefficient>
<FrontalArea>23.36</FrontalArea>
<TireDiameter>25.5</TireDiameter>
Here's my virtual dyno on JB4 last night running about 15psi, no CPS, on pump gas and 80/20 meth
Now compare that with the run that was done on RBs with 75/25 meth in pretty much same conditions inside the dyno shop back in March. The car was running the Procede V5 with about the same boost and also no CPS. This Dynojet (Champion Motors) is well known to the N54 community in the Toronto, Canada area and many of us have tons of dynos from the place so its 100% legit.

You can still log a Trifecta tune with HPT, but you need the interface & software.
Vince uses code he wrote himself and his logging software is for him to view the tune to tweak it.
I ran the virtual dyno software on one of my LNF pulls and it seemed low. See what others say.

Ive been using this just to see how I was affecting my performance with changes to my tune/experimenting.
For myself, the only way I was able to get somewhat accurate readings is to use the SS/SC settings and make changes accordingly to weight, final drive, BARO and temp. Right off the bat, you're going to see crazy spikes in both HP and TQ, so it will be helpful to look at a previous real dyno run/sheet to see where torque and HP peaked in order to weed out the crazy spikes (mine said 469/598 @ 3900 rpm, at the beginning of the pull... lol...)
In doing so with mods in sig, I came up with 337/378 from a 60-100 pull. Not sure how accurate it is but the numbers seem to be pretty accurate given the weather conditions, my tune, mods and previous E tune only numbers from last "winter".
Edit - Was never able to get BYT's street dyno to work on his tuning spreadsheet. Always gave me errors etc. I'm sure it's more accurate than the VD too.

It's not 100 percent accurate but it is pretty darn close, reads a little high lol. Just shedding some info out to the community and if I could get some help on how what software to use with this..
