I have a wideband commander which data logs along with the DJ LCD. I've used them together before with my old bike, but honestly, I didn't know what I was doing and also didn't know I could transfer the data to a .csv and look at it on a table.
Questions for you good sir:
What AFR are you tuning for? I'll be running naturally aspirated, 93 octane pump gas, no nitrous or other power adders.
Are you only data logging on the track or do you hit a back road and make a few pulls that way?
Since the bike is new to me, i'm basically starting from scratch with nothing to go off, except maps i've gotten from folks here on the forum.
thanks for the help.
For a naturally aspirated engine shoot for around 13to1 AFR at WOT, but don't get hung up on the number, if you're between 12.5-13.5 you're good to go. Low and mid load you can shoot for around 14.7 AFR for better gas mileage. Tune it to what the bike and you like really. Take your time with it.
For octane try running 89 or even 87 octane, if the bike doesn't ping, then you're good to go, if it does, raise the octane. Higher octane doesn't make anymore power.
I only datalog at the race track..........but that's because that's where my bike spends most of the time and I log acceleration rate and tune that way.
Once you get your fuel where you want start adjusting the ignition timing, that's where you gain power, that's where logging acceleration rate tells me if the bike makes more or less power. Having the bike on the dyno can accomplish the same thing.
Here's where things get kind a tricky, correct ignition timing depends on many things, air temp, baro pressure, fuel type, dynamic compression.
Starting from scratch is fine, you get to learn what the bike likes in the conditions that you live, start with factory map ( it's pretty damn good) and start making 1 change at the time and see how the bike responds. Save the data from all the different conditions and learn it, once you'll get a hang of that, you will know what your bike will like depending on the conditions and you'll be able to adjust it as conditions change. Remember, tuning is not magic and it doesn't happen over night, and there is no magic tune that works on all the bikes in every city in the world.
