So today we did a little Dyno-jet live remote tuning this morning, sucked cause soon as we turned her up it started slipping the clutch, but we took this opportunity to show the community that my Virtual dyno tool works very well to get an idea on power with out spending the cash on renting a dyno.
I try to educate customers and owners, that every dyno is going to read different, dyno jets typically read the highest, but if they are old, and have not been serviced, and calibrated they wont read "Correctly" anyways. MD read even lower, and same with dynapacks. SOOO again a dyno is a TUNING tool, to dial in timing and smooth AFRs. I can do ALL this on a VD as long as the customer has a good flat, strait road, and grip of course lol
SOO lets compare a little dyno vs dyno here
This is todays session
The blue 464/304 was on 15psi
This pull below was done on the way home and thrown into VD.
This was about 13.5 / 14psi which typically youll see anywhere from 15-25HP Per psi in your typical mid frame turbo... So this is matching up VERY closely to real dyno data.
not to mention the graphs are very similar.
You also have to remember the dyno LOAD vs the real STREET load is different this will shift rpm and curve a tad... but again... its very close.
Typically I see 5-15HP error range on my VD compared to dynos, I've done this a few times, but wanted a update FI car to show you guys its pretty nice little tool.
I'm not saying DON'T use a real dyno, they are GREAT tools, (I'd Love to own one my self) and very accurate when serviced and calibrated, and if available, its a great way to dial In your cars power, I'm simply saying, the VD is a GREAT tool for remote tuners like my self, or if you 1. Do not have a dyno that's close, or 2. don't want to spend the rent money.
90% of my customers are remote tunes, I've tuned guys all over the world, and you can get a amazing tune on the street.
Dynos don't make your cars fast...… The tuner does
I do live Remote dyno sessions of course, I also can do live remote track sessions, just have to schedule those of course.
Thank you all for the support!!!
Cant wait to work with all of you in the future!!!
I do use virtual dyno also and have a small question. I saw your recent graphs are between smoothing:4 and smoothing:6 . On my pulls, I saw that the gap between smoothing 1 and 6 could be from 15 to 40+whp depending on how the clean the pull is. How do you know which smoothing to use to have the more accurate graph?
By the way we can see that the real DJ Dyno is also at smoothing 5, which I did not know it would exist. I thought that a real dyno did not have to smooth the graph out...
Yes real dynos have smoothing factors too.. that's why this whole debate on "accuracy" is funny to me... every dyno calibration, ever dyno owner, depending on what smoothing they like to see ETC.. there's SOOOO many things that can change your overall power on a real dyno as well. So when dyno tuners wanna slack me for VD, I laugh. They just mad cause I didn't pay 30k for mine.
I typically use smoothing 4... seems to be a good middle ground.. unless the road was not smooth and we got bumps ill max it to 6. I have gotten some pulls in the past that where so smooth 2 even had a smooth graph lol
So just depends on data log, and if your data log is THAT bouncy that your getting high spikes, I wont use that, and get another log.
Its VERY important to have SMOOTH, FLAT, and not a WINDY day data log.
i saw a facebook post on vd last year, plugged in some logs and was surprised how nice the program was. also power fell right in line with where i was guestimating power should be based on the setup. honestly i only smoothed as much as needed to get a pretty smooth looking graph which was 1-3, usually 1 or 2.
Very nice to see this. I am one of his first customers and I can say he is an amazing tuner and a very good man. I have been away from the car scene for the time being but I always recommend AP1Cheif.
