ISF Data Logging
I want to be able to data log my car and use a program like Virtual dyno from my subaru days to estimate my horse power changes as I mod the car.
From people that don't know Virtual Dyno is a software that you use your car data logs to estimate the car horse power. It is used extensively in the Subaru and EVO forums for road tuning. It has been developed and is proven to read within 5% of a Dynojet. I also prefer the Virtual Dyno because you get real world airflow. The only potential issue that I see is that the 1:1 gear for the ISF is 6th gear and I don't think I can do a wide open pull to red line on the street
. A second or third gear will do since I am just trying to see the change in horse power as I mod my car. http://www.virtualdyno.net/
I am able to connect to the ECU with the Torque App and see throttle position, RPM, coolant temp, etc etc; but I wonder if there is anything else that I can use to log the car at a higher refresh rate.
The excel sheet (http://api.viglink.com/api/click?for...%2520Jan08.zip) allows you to manipulate the gear ratio, aero, and weight - which once adjusted, should bring it theoretically close to accurate for the F.
The data required is just time and RPM to work.

. I end up using VD in the end since is used in many different platforms. I will try to see if I can get to with the IS-F later today. Keep in mind that Airboy reads like a low reading mustang dyno
I agree with you a lot of people lie, they change correction factors, smoothing etc etc. The drag strip tell the real story.
Well I got it to work but I need something that has a higher logging rate. I also had to spend sometime figuring out how to convert the time stamp to what Airboy requires. For some reason my throttle is not 100% the log it says 80%
My car is a 2008 with muffler and secondary cat deletes it also has light weight 18" wheels.
So here is the plots:
Here is log

Here is my WRX with a 6466 turbo on E85, I miss the thing. I need another turbo car, I will probably end up getting a supra or an EVO.
Yeah do an Airboy with your ISF I would love to see how much is putting down.

Just to clarify - there will be no discussion of software piracy on this forum, especially for Denso proprietary software, but there are resources available to the public if you just look around.
