Problem with Log File??
I just did a run and downloaded my log file and then went through all the steps and put it into log tuner. When I hit calc tune nothing showed up in the VE tables at all, no hits no nothing. The spark tables on the other hand had lots of hits and a couple knock events in the front. When I view the log on the PV and look at the VE for front and rear it shows a graph of changing VE all through the log.
I'm soooo confused...why didn't anything show in the VE tables? Help
I'm soooo confused...why didn't anything show in the VE tables? Help
Need a little advice. I have a 2011 RKC 103 and have added FM Header, DT Mufflers, and PV Tuner. Jamie included a map, which got me about 90% to where I wanted, and after adjusting some of the lower KPA fuel table regions and Decel Enleanment, the scoot is running great with very rare popping, getting 40-41 mpg. I have the PV mounted on my scoot, and have noticed that I get some fairly frequent pinging and rear jug knock retard, as much as 3 deg. The region it is happening is 5th and 6th gear moderately aggressive roll ons starting at about 2600 RPM and mid 40's KPA to 2900 RPM and low 70's-80's KPA.
Since I have the general map and scoot running really well, I don't want to go through a series of tuning runs just to smooth out the timing. I was hoping to just make adjustments to the rear knock retard. I had the TTS on a previous bike, and am no stranger to tuning, so if that's the way to go, no biggie. What do you all think? Should I just adjust the rear knock or do tuning?
On a side note, if I go the full tuning route, am I correct in thinking that I will have to adjust Jamie's modified map back into closed loop and load that up to do the tuning (and use that map to generate the value file)? The main fuel (Lambda table's lower KPA region is less than .977. Clarification here would be appreciated. Thanks all ahead of time for advice.

I'm a total newby at this so you'll have to dumb it down for me. I'm using lambda since I have a 2010 SG. I created a value file from the tune you sent with the PV and the lambdas for a good portion of the table are .98 and .99. I am logging all the correct signals (double checked that twice already).
Opened the log file and hit calc tune.....still nothing in the Tuning Tables under Fuel.
I know this is operator error, so what steps am I missing here?
Edit: just looked at the log file in excel. There are no values recorded in the Set Lambda column. Is this likely the problem? What would cause it not to record that data?

I would go into your Spark table and pull 2 degrees of timing from 2500-2750 in the 60-80 Kpa range and this should take care of it. Also note knock retard events of 2-4 degrees are going to be pretty normal especially in some of the higher load areas, as long as these events are not outside the systems window of adjustment you will be fine. Some of the logs I have done in automotive tuning show nearly continual knock events under even normal operation with the ECU almost always pulling several degrees of timing to keep it right on the edge, that is the beauty of a properly functioning adaptive knock retard system
Before I got PV Tune working with the AT-100 Pro I started to manually retard the timing in this area, but the knock events kept coming. In a short time I had subtracted ~10° with no end in sight, and finally put it back to where it was and decided to live with the knock events. I never heard any knock under any conditions.
PV Tune has been trying to tune this out and is making very small changes, but it keeps coming. It has retarded spark 2-3.5° between 60-70 kpa @ 1750-2250 rpm so far, but every log has an event like the previous and PV Tune keeps pulling the timing. I'm thinking it is a false event and I should put the spark values in the PVT back where they were and deselect spark advance from being included in the final PVV file. I've replaced the spark plugs and wires since this issue started, but with no change.
Anyone else have this problem? Any ideas or recommendations?

knock
My situation is similar. I've had intermittent knock events usually starting at around 60kpa and 2100-2500rpm only on the rear cylinder, happening maybe once or twice per 15-min. log, sometimes not at all. This is barely any load at all and seems to occur when just cruising down the road maintaining speed, and AFR's don't seem to be a factor.

Thanks RK and Iclick. I haven't had any real "knocking" , just some pinging and it is also intermittent, but I can hear it. Has been hot and humid here, which may contribute. I'm taking Jamie's advice, and monitor, but am not too worried at this point, unless it gets noticably louder or is occuring a lot in the fall and cooler temps. Even in these temps, going down the road my ET is no greater than 253, usually in the 240's.

I want to clarify something I said a couple of weeks ago, for those of you interested in tweaking the MPG calibration. As I mentioned back then there is a beta FW being tested that has a "Trip Center" display, and you can adjust the three MPG calibrations independent of VSS and the MPG Calibration parameters in the tune. I said that VSS and MPG Cal were no longer going to be used, but this isn't quite right. They are still there and you can use them, but the Trip Center parameters are downstream of those two, and you can adjust them independently. I hope this is clear now, as I made it sound like the two parameters in the tune accessible from WinPV were no longer going to be used. Not so.
So, until the FW with the Trip Center is released you can still tweak your MPG calibrations the old way and it will carry-over to the new.

Iclick- I had the same scenario, except the front cylinder. I am using the SEpro super tuner, but same issue of false knocks in same ranges. I too reduced timing as much as 8 degrees to the point the bike ran like crap. I too changed plugs and wires, no improvement. Wires ohmed okay with meter. I ended up turning knock retard off, putting timing back and riding in 101 temperature to audibly check knock/ping. Didn't have any. Increased timing slightly to the point if pinging and then backed off 2to degrees to no pinging. I left knock retard off. The bike runs much better. I think the false events were causing too much retard and in turn sluggishness. I know knock retard works, but it seems to be over working in my case. Hundreds of thousands of bikes without it, added mine to the group as well. I do thank Jamie as well for his time on the phone about it too. A faulty injector is the only thing discussed that I didn't try. Plugs look equal front to rear, a little rich, but I am happy.
