B8 Ko4 owners follow up thread

[Comfy Pursuit]

I was the K04 Beta 9 months ago. Your tune is probably based off of my file ;-)

You’re the Hawaii guy I’ve heard about. So did this car get any mapping done in Utah at elevation? I’m also assuming you don’t have an e85 compatible model as they don’t yet have a file available.

My K04 file was written by IE’s lead engineer in SLC using their B8 A4. My vehicle was never in Utah. I emailed him numerous data logs to get my file dialed in for sea level.

Although my vehicle is flex-fuel compatible, E85 is not sold at the pumps in Hawaii so I was not interested in an E85 file.

I believe my file and several others on here were based on Perry's. Quite honestly have to thank Perry for taking the plunge and getting all the kinks worked out. The beta version tunes they have sent me have ran flawlessy. The car is my daily driver and it is perfectly suited to normal driving but has a smile factor when you want to drive like a moron or for that matter make a moron wonder why he just got left behind by station wagon.

I took the liberty and put your latest log into a couple of charts. Besides the two spikes in boost between 3500-4000 RPM, you boost looks very good. You hold 20 psi up to 6300 RPM and ~18 PSI all the way to 7000 RPM.



And you are flowing some serious air through your motor. 330 g/s is amazing.



That CTS Turbo K04 matched with IE software seems to be performing quite well.
