First log is running T6, second log is running T7

Thoughts, comments, concerns?

T6 looks perfect. What tuning?

Looks great! First graph is perfect... 2nd is the limit.

Yup, T6 looks to be your sweet spot. Notice that your timing BTDC is better almost across the board when on T6, compared to T7

Just to educate me, can someone answer what to look for on the BTDC log as ideal?
I've never really looked in to that and always just kind of used CF as a guide.

Did the logs after about 150 miles of spirited driving to make sure the IAT's would be "at their worst".

Here is a log of T6 that I did before plugging in the Water/Meth. I havent dialed in exactly when it should kick in etc.. But am curious as to if it made that big of a difference in the timing BTDC, Just like rxrep, I am not entirely sure what to look for in that area.

Nice chart.

[Redgoat]

Agreed! Excellent chart thank you!!

[dirtybrd]

Do you mind doing a logs with EGT? Also, what boost are you running?

[rxrep]

Can anyone give wisdom on interpreting BTDC? What is good, what is bad, what causes bad and how to correct it?

TIA

Nice chart.

Gracias! they should post it in the sticky thread for logging.

[Audi Skate Snow]

Agreed! Excellent chart thank you!!

No prob, looks like your running perfect also!

Do you mind doing a logs with EGT? Also, what boost are you running?

Sure can! Want just EGT's? Or logged with anything else? Boost is 22 PSI.

Good to hear!! So much more that I have to learn about what everything is.. love how helpful everyone here is with sharing insight and everything.. Most of you guys should be labeled as the unofficial "Audi Tech Support"

"Good" BTDC numbers depend highly on fuel octane and boost amount. Most logs I've seen with revo GTRS drop down to low single digits at boost onset, about 4000rpm, then go up to 6-12 degrees near redline.

[Redgoat]

So.. your saying my BTDC numbers are good? Sure hope so LOL.. What is better? IE double digits through boost?

EGT and timing. Thanks!
