Some new summer vag com testing- APR 93 St 2 V2, GIAC 93 Stage 1, Revo 93 Stage 1

[tsivas27]

Hey guys- I am sure you know or have read about these types of threads... Felt like finally writing up some basic Vag Com comparisons today. Decided to take a break from the Vbox testing. The delay in posting was due to finally getting the V2 flash. The V2 flash was done via bench flash @ Elite Motorsports. Kai is a good guy. Audi enthusiast at heart.

This is a similar test to the post below done in the winter.

The cars tested were: APR Stage 2 V2 93 tune, GIAC Stage 1 93 tune, and the Revo Stage 1 93 tune

• We use the same strip of road that we vbox on. 0% decline/incline.
• Temps were in low to mid 70s for the runs. Air pressure was about 1015 mbar for these tests.
• Same parameters... Third gear log from 2000 RPMS to redline.
• The Revo Flash is their most up to date 93 tune, so is the GIAC.
• All cars were running pump gas.

Some quick comparisons of APR St 2 Version 1 to Version 2.



The boost difference is that drastic. Yes u feel it instantly and it pulls really hard to redline.

Good news is the bypass stays shut. I have to do some cold weather testing to see how it does in the winter, but I am sure the issue has been addressed.

Here is timing comparison of Version 1 and Version 2 in winter/summer and on 93 pump gas, as well as seeing how much different the timing is between the 100 file has
(Version 1) compared to the 93 file.

Seems like peak timing has been reduced with the new V 2.0 compared to Version 1. No codes came up on intial vag scan. From the timing logs below.. seems like the car can benefit from some more timing up top.

Here is graph comparing all 3 setups with Ignition Timing Angle. The Revo file definitely stands out and is running a little more timing than the other two.

Here I added the APR 100 St2 V1 file for fun to see where it was compared to the pump files.

Here is a comparison of Boost in PSI for all three setups. The APR stage 2 v2 setup definitely stands out.

Bypass Valve % between the 3 setups. The GIAC car seemed to open up slightly on all the runs we did.

Here are the APR St2 V2 timing runs. Seeing much less timing pull than the previous version. Looks pretty good.

Here is one of the timing runs for the GIAC Stage 1 car. They all looked pretty similar. Definitely pulls timing. Seems a bit much. No codes came up on inital vag scan. Ambient Temps weren't that bad when it was tested. Bad gas maybe?

Hey!! we finally saw some timing pull on the Revo Car. Could it be the new tune? Who knows. All I know is that this is the first time ever seeing timing pull on this car. DA was about +1900 that night. Temps were in the mid 70s. Car doesn't seem to run as well in the heat vs the winter time. This is also seen in the updated Vbox testing we have done. (see list below). There was a code on initial scan that we found- cylinder #5 misfire. We cleared and will monitor .

I will do some really thorough vag com testing one night with all three cars. This was just a basic logging session/code checking session I do usually before we do the vbox testing. Just like posting stuff up for u guys.

Stay tuned.

Oh and here is the Vbox database that we have compiled on our private test track.. Every car has been tested on same strip.
