Question about logging

[JPriami]

I read you r loggin information. Good write up. But I want to ask should I already be driving down the road to have my RPM's up already between 1800-2500 then start logging and keep the rpms between those ranges. And let it fill the log before I stop the car? Or should I start the car start the logging at a stand still then drive and drive normal where I might have to slow down or stop etc and let it fill the log with normal driving start to stop with most of the log (75-90%) being in the 1800-2500- range?

Oh and another question does it matter if the AC is on?

do not have the A/C on... that creates additional engine load and affects the log data...

for logging, I would get the tool all set up and ready to log, but do not start recording yet...  then, once the car is up to normal operating temps and you are just gettin on the highway, then start the recording/logging...

then just do your driving/cruising keeping the rpms between 1800-2000...  don't worry about having to slow down for traffic or what not, that's fine...  that data will be filtered out and not used in the ltft calculations...

let it record until it says it's full..  or about 15 minutes... whichever comes first...

and, select the FAST RATE when you do your logging...
