Data Log Help

I'm doing a few Data Logs. Any insite on weather they are good or bad would be greatly appreciated. I'm learning but somewhat have an idea. Always good to have a second opinion.

I'll keep this thread updated instead of making others.

I've tried posting in the Data Log Thread but no one apparently visits there.

Thanks in advance.

This is the Cobb Stage 0 Stock Tune to see what the numbers are and this is what I've come up with on a 3rd Gear Pull.

datazap.me | Mikost | Cobb Stage 0

My guess would be to say that at 5500RPM, when you let off at the end of the pull you are going to see all negatives on the charts making that normal. Negatives are bad so my concern is why are they all over the Stock Tune?

I know a lot of people do not know much about tuning since I haven't gotten any responses and this was posted 4 days ago but would be great to have some in-site .

It is interesting to see that the turbo never maxes out as the waste gate duty cycle never goes to full load. Even interesting to see as well is that there is a 25* climb in the charge temp, even with a mild boost curve and a brief pull in third.

As long as the ignition corrections do not get past -3.00, it is perfectly fine. The OAR is sitting at -.75, with -1.00 being ideal, which probably accounts for the degree and a half of timing being pulled. Again, no worries here.

In short, this Stage 0 tune is ultra conservative. Probably more conservative than the factory tune.

Good Morning.

Here is my Brand New adjusted Tune.

A clean 4th Gear Pull- datazap.me | Mikost | Updated 4th Gear Pull - Clean

Take a look.....
This looks great! Getting a great boost curve and adding timing throughout the pull. Can't ask for much better.

The charge temp climbs 54* in this short 4th gear pull, when you're in ambient weather of 26*. Imagine when the summer time comes around and you're seeing charge temps of 140*+ on a 80* day. The next modification needs to be an intercooler; pick up Depo's 3.5", CP-E's 3.5", Levels' 3.5", or Steeda's 3.5" intercooler to keep tame the charge temps.

I know its crazy. Just normal driving out of boost it stays around 40. I need to find one for a good price. It's supposed to warm up just a little bit by us this weekend. 31 Sat. 35 Sunday Ill see how much it changing just with the little temp change.
