Thanks! I'll run the Autotune a few more times and see how it does.

Next question. I'm planning a trip out through AZ in a few weeks 2 up, fully loaded pulling a Bushtec trailer. Should I run the autotune a few times with this setup before I head out? I'm not sure if it would tune different loaded up?

Start with auto tune runs before you mess with anything else. In addition to removing 4 degrees of timing it sets your afr to 14.7 for your whole fuel map. This lets you gather data from your O2 sensors in areas that you normally wouldn't get O2 data in. This will let you get your VE's dialed in, that is how your ecm knows how much air your motor is taking in. Do your auto tune runs until you have less than 5% max change in VE's. If you don't have your VE's dialed you will never get your tune dialed in.

Read through the last third or so of this thread as it has good info in it. That is about when the auto tune feature came out, before that it was all done with the logtuner software.

Edit, took so long to type this on my phone heat wave already answered you.

Reading through the Autotune manual a bit more it states that the Knock adjustment is disabled in Basic mode and not recommended? will this work with the narrow band o2 sensors?

Basic mode is for narrow band, pro mode is for wide band.

It's difficult for autotune to accurately adjust spark advance while using the Basic mode (stock narrow band O2 sensors). The reason it isn't effective (without some manipulation) is because it starts by removing 4 degrees of spark across the table to start with. Once it takes the 4 degrees out, it has effectively eliminated most knock events unless you're running a map that wasn't designed for that engine build.

That's why it's important to start with a map designed for your bike. Dynojet provides maps for most basic engine builds in their library map. If you bought your unit from FuelMoto, they provide an even greater library of custom maps.

If I were you, I would create a map with my regular load (no trailer) on the bike using the normal gas you run with using the Basic autotuning capability in the PV. Its easy, straight-forward and if you start with a solid map, you'll finish with an excellent customer map for the bike you ride.

After 3-4 autotunes, I would save that map in one of the 6 PV slots and call that your base map. I would then load the bike up with all the weight you expect to have on the bike for your trip, fill it with the gas you're likely to be using on the trip, and then go and have some nice autotuning rides before your trip. Autotune your base map with the full load on the bike and save this new map as your "trailer" map onto the PV.

Now you'll have a custom map designed for riding normal PLUS a second map for when you have the bike loaded up. I think you'll be pleased since you'll have both maps with you at all times. If you end up disconnecting the trailer for a bit on your trip you'll have your custom base map ready to be loaded to the bike. Good luck.

Great advice Heatwave! I'll do just that. I started with a map from Jamie for my bike and build so I know I'm pretty close. I do get some pinging when it gets hot. Also, my gas mileage sucks so that's really why I started digging into this.

Am I right in deducing that it's not a good idea to try and use autotune for Knock events? Once I finish with the autotune I'll start pulling out some spark advance in the areas where I see it.

Thanks for all the help. You guys are great.

I think you'll be surprised that once you autotune 3-4 times, I believe any knocking events will be gone. Try to get 20-30 mins of riding for each autotune session. And try to ensure lots of load variation such as low rpms, hills, highway on ramps etc. These different ride conditions will provide better data for the autotune algorithyms to make adjustments to the VE tables. I think in the end your pinging will be eliminated.

Worst case, if there is some pinging, make mental note of the rpms and how much throttle you were applying and send that info to Jamie along with your latest map in an email. If you bought your PV from him, he'll modify the spark tables for you to get rid of any remaining pinging and send you an email with an updated map to upload to your bike.

Basic tune file question on Autotune Basic. I'm sorry but the directions go so many different directions that I find them very very hard to follow.
So you ride and save the autotune file. Then on your next ride, you have to flash that saved file to your ecm to further autotune? Thanks.

Do an auto tune run and export the learned values.

Save that tune to an empty slot.

Flash that tune to the bike.

Repeat the auto tune process using that tune that you just flashed to your bike.
