PowerVision NB Tuning
Just want to start a discussion on tuning. I don't know if I doing good or bad, but I seem to be getting pretty good results.
2011 FLTRU Harley standard stage 1 on filter, V&H Pro Pipe 2 into 1, RedShift 525 cams, adj push rods, fueling tappets.
I have had the PV for several years and have tried many different scenarios for turning. Here is my latest and makes sense to me but wonder what others think.
I got Megalogviewer to be able to view the datalogs.
I started with a base tune from Dynojet and as always they are not a perfect match, but a good starting place. At first I did a standard autotune run to get the VE's a bit closer. After that I just record datalogs from my runs. I then take the logs and open in megalogviewer. I have been tuning my ve tables strickly by the O2 readings in the log. With the logviewer I can see where I am rich and lean. With the Narrowband it a high/low signal. So my thought is they need to to be switching pretty steady and not a flat line at one or the other. High is rich and low is lean. With this viewer for example you may see at 2500 rpm and 45 - 52 map it is a constant high signal. So this tells me I need to adjust the VE in this area and bring it down. Also look at surrounding cells as a big difference in values and cause this as well.
Result: I have not had a dyno run I have been comparing the old fashion way by how well I run against my riding buddies. I have seen my temps decrease and my mileage increase. Just about across the board I had one cylinder at one state and the other at the opposite. Now things are coming together and I think I'm seeing positive results.
My question is as I'm not an expert. Does this logic make sense.
Appreciate any input as I am still a learning DIYer.
