I was just going through some logs and thought i'd post this in case anyone was wondering what it looks like. All my logs are taken in the same test area that is slightly uphill and taken in third gear. This one was taken back in October.

Be on the lookout for a complete set of before and after logs of mulitple variables in several different states of tune from myself and Jeremy. That's the teaser for some upcoming testing that will be done on these cars. No d1cking around for the B7.

cheers! Mike

Where you getting this from? Which (what is it) log numbe?

parks853

it is lambda actual located in block 31. That value is the one you multiply by 14.7. The reason I say log it with 34 is because 31 has no RPM reading.

That's the typical OEM "downhill" AFR.

Too lean at low RPM to make peak torque and too rich at high RPM to make peak HP.

in that the torque comes on almost instantaneously and the hp is right there hanging out til redline with very little drop off. What I noticed APR has done is fatten up the low end a smidge and they are also making very smooth torque and talk about hp...I see only a loss of 7hp from the peak 210whp at ~5500rpm until the car hits the rev limiter at ~68000. Pretty remarkable and unique. cheers! Mike

Did you figure this out?

Tomasz@Startup

Not yet, but your post below answered my question. Still waiting for the new CAN cable...

parks853

if you need help when you get the cable just ask.

Tomasz@Startup

Will do. Thank you VERY much.
