Looking For Advice
 

I race a stock C5, A4. I tune it myself but I have never started at scratch and gone completely through it all. My car runs so consistent I am reluctant to make too many changes.

I have installed a Blackwing and 3:42 gears. I have adjusted the shift points and disabled Torque Mamagement. I have adjusted the injector flow rate to get my fuel trims zeroed out. I know that's a shortcut but it works.

I have scanned this car many times at the strip and the timing bothers me. But, like I said the car is consistent. At the initial hit of the throttle the timing drops to 2 deg total and then immediately picks back up. I don't have a clue what is causing this because I have triple checked everything. Should I add timing or leave it alone? :shrug01:

de-sensetize the knock sensors a bit to see if that eliminates it. Also, copy & paste the high octaine tables to the low octaine if you always use 93 so there is no switching between them to keep consistant.:thumbsup:

Thanks Tracy. The low octane table already matches the high octane. How do I de-sensitive the sensors?
