Power Vision Information Thread
For the life of me I can't figure out how to do a data log run the old way now (where you enter 319245) that I've updated to autotune. I see where I can enter the code, but I can't seem to get the logs to the Log Tuner software. It saves them as pvv files, while the Log Tuner software is looking for stk's (I guess?) so I can't load the logs. I just want to see where my spark events are like I could before? All I can seem to see at this point are the VE tables. Frustrated!

Charge dilution effect
This is the VE Front Cyl with a valley at 2000 rpm. I'm not concerned with the peak at 1250 rpm/30 kpa for now. What I am going to do is to increase by 20% the value in the CDE table at 1875 & 2250 rpms.
This is the VE Rear Cyl with valleys at 2000 and 3000 rpms. I am ignoring the peak at 1250 for now. I am going to increase by 20% the values in the CDE table at the 1875, 2250 & 3000 rpms.
After I do a autotune datarun I would expect the VEs to increase and slowly eliminate the valley. I guess I would continue to do this until there was little to no change in these areas.
So, what is the difference between this and smoothing? Does the CDE more accurately predict what the true O2 composition is in the cylinder?
I will add that earlier today I smoothed these areas and turned of the Adaptive Control switch. The motor seemed to run much smoother at 3000 rpm. I don't think it was my imagination. However, I would like to use the learning ability of the ecm.

That code wont work anymore.
Use auto general logging same thing but you will not seen the green screen like before you will see gauges just go with it hit start your logs will generate READ posts #3211 #3182 maybe a few before and after.

Thanks guys, I'll give it another try tomorrow. I had been selecting tuning for narrowband O2 sensors instead of general logging, and I assumed that I would be logging only the information displayed on the gauge I had p on the screen. Apparently I was wrong on both counts!

Has anyone noticed any issues with AFR in the 105 level ECMs with the 2.0.0-1193 firmware? I'm having an issue with displayed "Set AFR" locking in values are not resident in my AFR table.
Here's the set-up:
I load a calibration into the PV (AFR table cells have a range of 12.3 -14.4) and ride the bike. After about 15 minutes the Set AFR begins indicating values different from what is reflected in the table for a given RPM/MAP. Where I should be seeing a range of 14.1-14.3 for the region of RPM/MAP, I'm seeing .3 -.6 higher/leaner values. Eventually, the indicated AFR will scroll to 14.7 and at that point latch that value in, regardless of TP/RPM/MAP. *Before some asks, Yes, this is after the warm-up AFR event is expired, and No, AT is not enabled. In fact, I've held off installing the wide bands because of this anomaly.
Anyone have a link to the previously released PV Firmware (sans AT functionality)? My fear is that the current Monte Carlo method of AFRs not just an indication issue, and may be creating overly lean conditions. With brand new motor work I'm apt to default to the safe position...

How many cells before you export
I have been getting 118 to 126 with a avg of 1 to a high of 4 for the ve's.
The high will go up and down by 1. When I see the high at 1 is that when the ve's are good?
Thanks Bill

If you're confident that you're hitting a broad range of cells, and your max change is 4%, then I'd say you're there. It would be difficult to get max down to 1% with these engines. My last run I was at 0% avg and 5% max, now I'll start working on my timing. Once I get that done, I will most probably do another VE collection to see if it tightens up anymore.

Wow, lots of stuff for a new bee to learn.
Thanks Sam2010,
I did see that doc. from Dennis and I don't doubt his knowledge on the subject.
I was just wondering if FuelMoto had a certain method of doing a tuning run. I consider them the experts since they were in on the development of the PV. I would think after they have done countless runs that they have pretty much perfected what to do and how to do it and what not to do on a tuning run. I was hoping they would chime in and give us some professional guidence.

getting a PV in November, hope I can use it without having to get an infusion of brain cells from Stephen Hawking.....
Watching this thread with much attention, and anticipation to understand the processes to refine a base tune that is supplied by FM. I hope that the base MAP by FM are pretty close to begin with, in my case a TW222 cam upgrade in my 103.
Cheers,
Mark
