B8.5 2013 APR Stg 2/APR TCU Passes at Milan

Had a great time meeting up with a group of B8’s, a B6 along with a monster RS7 ;D

This was really the first time I legitimately ran my car with the TCU tune. I did make a pass back in June at Milan, but the track was a Charley Foxtrot and only got one pass after 2 hours of sitting around. Previous best was 12.45@110

New mods I was running were
Factory short shifting DSG => APR TCU with LC at 4k
Nuespeed Exhaust => Milltek Resonated
Factory cooling => AMS CPS (thanks again Glenn for hooking up the deal :smiley: )
Stock Cats => JHM Test Pipes
1.5 gallons e85/8 gallons 93

Mod summary: APR Stg 2 3.1 93 file (1.5 gallons e85/8 gallons 93) - TCU tune with LC @4k - AMS CPS - Milltek Resonated Catback - JHM Test Pipes (with CV welds ;)) - Stoptech BBK w/ LW Front Rotors - JHM LW Rear Rotors - Roc Euro Intake - 19" forgestar flow formed wheels at 22 lbs (LWish) - spare removed

Best trap 12.297@116.18, best ET/60 12.252@114.47 1.89 60’

Car 130 is mrmomo, who ran next to me for the majority of my passes…you can see he was killing it. I’ll let him chime in to discuss his times, which were great!

I logged 4 of the passes. Feel free to PM me and I’ll send you logs. I’m not posting them because some morons have posted graphs from my previous logs totally out of context without asking me.

General Comments

  1. Most importantly, my timing pull is down significantly. I logged all 6 knock sensors, and was seeing on average about 2 deg of pull and a max of 4. This compares to a regular value of 8 degrees before. I highly doubt this is due to the 1.5 gallon of e85, but anything is possible. My theory before was that the timing pull was due to false knock from my exhaust. I have the exhaust off and a new one on, and the timing pull wasn’t there. Not sure if that’s conclusive enough but I’m pretty convinced. The new exhaust is a lot quieter and I feel no vibration at the pedal.

  2. I think the TCU tune was helping me in the beginning and hurting me towards the end. It felt like the trans was slowing down on the 2-3 shift as the night went on. Not sure if this is due to trans temperatures climbing? The fact that my et’s were steadily going down is not a good sign. I tried one pass without LC and it shifted the trans at 5.5k RPM each time. Could have been due to the trans oil heating up? I drive with manual mode 100% of the time (and auto upshift disabled), so this configuration would never affect me on the street.

  3. My launching sucked. I’ve seen 60’ times in the 1.7x before, last night, 1.89 was my best. I should have spent some time figuring out how to use the other LC points. Would have been a good idea to use 3k instead of 4k. I forgot a tire gauge and I didn’t do a good job adjusting the tires. This probably would have helped. But we were getting a lot of passes, so I didn’t stop to make adjustments like I should have.

  4. I might try to go again one more time to see if I can sort the launch out. I’m sure the trap would probably decrease (was really flying once my launch hooked) but it would be nice to see the car into 11’s on pump.

Happy to see that the car performs like I was hoping it could. I’m more than happy to be in the upper echelon of pump gas times. Modding the car to me is a great way to learn about cars (which I am relatively ignorant to) and enjoy various aspects of performance improvements. Once APR releases program switching I’ll try to get a race gas run just so I can tick that box. Anyways, had a great time meeting up with everyone.
