Thank you for the support Ugnius!

Are there specific procedures in data logging?

Flooring the accelerator pedal on 2nd gear at 2000-4500 RPM...

I am recording KR -4.0 Max on 93 OCT stock tune. Intake temp is 200deg F, oil temp is 180deg F.

Please advice,
Levi

Did the wheels spin when you did that log? Was the steering wheel straight?
Also 200F for intake temps is pretty high, there's a chance the car was absolutely heatsoaked when you logged.

It is possible that the engine is heat soaked. It was one of the hottest day here in New York.

No wheel spin and wheels are straight.

What is the correct way in data logging?

Thank you for the detailed and safety instructions!

Now that we know hoe to properly data log,

Is negative KR -2 max considered safe?

There's no "correct" way. Whatever results in consistent usable data for the situation you want to tune for you're good.
So this is how I do it, after driving the car for at least 20 minutes started cold:
  • Drive the car to the spot where you usually take your logs;
  • bring it up to the right speed for the gear you want to start logging in;
  • push the record button to start logging;
  • look ahead and on the road sides, make sure there's nobody or nothing that could endanger you or become a danger for them;
  • floor it PAST the RPM or speed point you want to have usable data for;
  • start slowing down, do not search for the record button at this point because you're at a higher speed than normal. Sometimes youo may be at 60mph which is 100-120 feet away from a complete stop (depoending on the car, surface, tires, whatever), some other times you may be at 100+ which is 300+ feet away from avoiding a collision;
  • once you're back down to a safer speed press the record button again to stop logging.

It is absolutely no problem if you log 10-15 seconds before and/or after the actual pull with the data you need. You can export these in CSV format and trim the data in a sheet application such as Excel/Libreoffice Calc/whatever.

I just purchased and was able to install the 93 stock tune on my ND and I have to say thank you. I cant wait to start adding more tunes with power options. Speaking of which, this is all very new to me and I really dont know how to go about getting more / different tunes when I do add power mods (different from which is already available).

I hope to see more tunes from you guys!!
