You did good for not having a screen to watch. Once you can see what cells you're hitting and how many hits you rack up it will all make more sense...and be more fun. It's like a video game trying to get all the cells. Don't panic when you see the error messages popping up. All they're telling you is you're not collecting data for whatever reason. Could be VE's changing too fast, MAP is too low to collect valid data, o2's went open loop on you, etc. Usually a slight twist one way or the other will correct it.

 

All engines have a certain amount. Different exhausts have different characteristics when it comes to reversion. If you really get interested in what causes it, ie: open exhausts, cam overlap, etc. do a google search. there's alot of articles on it. It's not really complicated but it does requires a bit of knowledge on engine flow characteristics.

Yes, I've played around with it in the PV. For the most part it's just another algorithm to manipulate VE's. PV can't really measure reversion. But it can identify a possible reversion issue by showing you VE cells that just refuse to play well with others. No guarantee with that either. In a nutshell, if you look at the 60 kPa cells on your VE's and the VE's to the left of that 60 kPa cell are higher you could play with the CDE table to bring that cell to the left just lower than the cell to the right, of the 60 kPa marker. Or, you could attempt to bring a low cell, or a string of cells, up or down. When you look at the picture graph of your VE's you'll see high's and low's. The theory is to try to bring the lows up and the highs down. This attempt, and I use that word lightly, will creat a smoother VE table. When the ECM interpolates a cell, and the surrounding cells, it has less math to do. The less work the ECM has to do the quicker and more accurate the results are. End result is a smoother low end response. And, just a guess, probably less crap in the AFV's.

I find it difficult with PV. It just hasn't evolved enough yet to give us a quick way to identify the correct cells to play with. I spent hours trying to do it the correct way and ended up guessing and experimenting. I, somewhat accomplished settling down some high VE's on th rear cylinder, but it was a guess. It started getting in the way of my beer drinking time, lol. TTS has a real sweet set up for this. Pretty much graphs out where the 60 kPa cells are and it's obvious by looking to the left if there's an issue and if it's even worth wrestling with.

Personally, if you're VE's look pretty nice...nice flow....and no real obvious high or low areas, I wouldn't sweat it, unless you get really bored one day. Get the VE's dialed in and a slight bump in the timing and most of these bikes will run pretty sweet.

 

How many pings are bad? I had total 50 pings (20 front, 30 rear) on a 40 mile ride today. I plan to look at some of my logs to work out where the pings are happening on the rpm/TPS table.

 

when you look at the logs try to note how many degrees are being recorded.

not sure if you are describing the degrees being pulled or the total number of events?

 

How awful!!!

 

Does the PV need to be plugged in to do auto tune basic ? or can you check it after ride? Thanks

 

I realy wish there was a more detailed vid on how to work with auto tune. I have the initial process down but this working out hits in the cells thing is all new to me.

 

Yeah they really dropped the ball with the documentation and user guides. While the more basic functions of the unit are pretty self explanatory there is no real in depth guide to using the thing. stailjim and wurk truk are a wealth of knowledge on this thread, another helpful source is the tts user manual. While the interface is different a lot of the functions are based on the same concepts, it's worth downloading.

 

It needs to be plugged into the ECM on the bike, but it does not need to be mounted on the handlebars.

Also, the AT-Basic (and Pro) tune, is saved to the PV after the tuning session is completed, and then, at the users decision it can be flashed to the ECM.

It doesn't do the tune in real time as your riding, although it does build the tune at that time.

 

Is possible to start an autotune log and then swicth the PV display to one of the guages screens while your doing the autotune run? if it is possible what are the steps?
