I don't think miles driven has anything to do with having a successful autotuning session. It's all about the quality, consistency and number of hits per cell that will help dial in the VE. You also have to do more then one tuning session. It gets to the point that you should be comparing the % of Delta between generated tunes. I've heard 5% as being minimally acceptable. I got mine to 2%. After I get my tune to this point, I will append multiple datalogging sessions to the same file (the more data the better) to be better representative of my style of riding, then generate a new tune. Is it overkill - perhaps - but I believe that getting the VE dialed in is key to the rest of the tune coming together.

Faster is not always better.

 

Ok, that raises a question. How can you tell how many hits per cell you are getting? Is it when the cell turns red?

 

Oh and by the way....100th post LOL

 

No. When you start you autotune you should see a spreadsheet sort of table with MAP at the top and RPM on the left side. Those little cells will have a number in them when it records a hit. When the cell changes color it is telling you that the number of hits established in setup has been reached. I believe the default value is 5. Not really a whole lot. The cell maxes out at 99. I'm doing this from memory so I hope it's accurate. I think green means none, yellow has a few, and red means the set value has been reached. Anyone done this recently that can refresh me on the color code?

 

Your right there is nothing stating 30 miles. I seem to remember reading somewhere that this was a recommended minimum. The difference being recommended as opposed to required.

Thanks...

 

I accidently found this site when googling for info on the DJ PV. I just started using the PV so I have many questions that I hope I can find answers to here. Hopefully I'll learn enough to give back one day.

Anyway, received the unit from Fuel Moto. It was supposed to have a cal loaded that matched my bike. Wow did they miss the boat on this one. The bike is pretty much unrideable. It shakes, shutters, spits, pops, and backfires insanely. Not sure what they sent but the bike sure doesn't like it.

My first question is how to attack the decel backfiring. Now this isn't just popping, it's backfiring. I lowered the decel enleanment some but that didn't help much. Also dropped the AFR in the 20 map column to 14.0 from 750 to 4000, still backfiring.

How low can the decel enleanment cells be lowered? As of now I have them set at .70 to .29, top to bottom. Should I keep going lower? Or should I toss a boatload of fuel at it in the 20 kpa column?

 

Something is not right. First off, are you positive you loaded the correct tune? When i received my PV there were several tunes preloaded. Call Fuel Moto to make sure you have the correct one loaded. Second, did you make any other changes to the bike? I would suggest checking all the connections to make sure there isn't a big leak somewhere.

 

Only one cal loaded. Nothing else has changed with the bike. Ran fine before this cal.

 

No other recent changes to the bike - just the PV tune? Tell us a bit more about your bike.

 

I would call Fuel Moto first and verify the tune matches your bike, they will get you headed in the right direction. Also as mentioned, list the details of your bike and any changes made.
