AccessPORT : Virtual Dyno feature
This feature is still in beta, but it’s coming along very nicely. Using a complex algorithm originally derived from a SAE paper we referenced, the AccessPORT can datalog key parameters from your ECU as you drive to determine peak HP and Torque (at the wheels). This takes into account everything from different gear ratios, Weights, and aerodynamic profiles of the various vehicles we support. Initially it’ll be available for Subaru models, with others coming along shortly.
Below are some example graphs from back to back runs made on our 2008 STi demo car. In the beginning, the AccessPORT will show you only the peak values but in the near future we hope to provide a tool you can use to download the full dyno graph off the AccessPORT and onto your PC for viewing, sharing, bragging, etc. Ultimately, it turns out some pretty accurate and consistent results which is very impressive!
Expect this to be available as a free update to download from our website in the near future.
Awesome!
What is the expected launch date of this feature?
hey, why no blog entry on the GT-R ecu ???
ya ya i know wrong place to put it. but you know you are doing it, write down the progress! your customers want to know!
Do tell us more. I have been trying to get these measurements for a while now with the least amount of expenditure of time and money. This sounds like an excellent feature that we all can anxiously look forward to. In fact, I’m surprised there are only two responses. I suppose not many have read this yet.
Any more details to further whet our appetites?
Aweson! Which version AP ?
Any update on release date of this feature
Hi. This looks to be a great idea. What SAE paper did you reference? I’d like to take a look at it. (I have a vehicle dynamics background.) Also, please be sure that once this feature is ‘official’ and not in beta that you make it very clear to users that wind conditions and more importantly any slope on the road can throw it off dramatically. I can foresee all sorts of guys claiming the feature is an inaccurate toy, but if I understand correctly that you put all drag, aerodynamic and rolling resistance terms in the algorithm, it should be as repeatable as a chassis dyno. Nice work. If you don’t have a scientist/engineer on staff and have any questions about the algorithms, shoot them my way – no charge. I love doing that stuff.
[…] a true dyno, but is it close? Does it have the feature where you can download the dyno sheet yet? COBB Tuning Blog AccessPORT : Virtual Dyno feature __________________ http://www.hypershift.net – quality web design 09 PG M6 w/NAV – 307RWPH – FI […]
I use to see this on my AP, do you guys know what happened? I updated something some weeks ago but now the dynamometer is gone right when the etune was finished.
your answer will by much appreciated.
We opted to remove the dyno feature from Accessports as it was not providing accurate data. We hope to re-introduce an improved version of this feature in a future update.

Hello, will the virtual dyno feature come back soon?
Hi Steve,
Most likely not at this point. The results can be quite inconsistent at times with the virtual dyno. So, it would need some work to be brought back and we have a lot of other performance features that are higher on the priority list right now.
would love to see this feature come back around – throw up a heavy disclaimer that its not intended to replace dyno testing due to uncontrollable natural conditions on most roadways but its nice to have some sort of estimation without paying 300 bucks to roll your car on a dyno for 10 minutes
