Power Vision Information Thread
disclaimer, i did not put this engine together. cranking compression is 210 (warm).
seems like no matter what, as soon as bike hits the MAP value for knock retard to kick in, it's retarding pretty hard, like 8 degrees. (BMF exhaust). more fuel, less timing, still thinks there's knock but literally when it hits 50kpa, it starts registering.
(on a dyno with O2s drilled into the pipe with rivnuts, AFR is perfectly reasonable at 13-13.5, 3000 rpm, MAP 50)

Power Core system does not open PVT. files stated on the application when i try and open it. Yet at some point my tune was updated and the trottle blade tables were either taken out or dynojet hide them from view. So what are us throttle by wire guys to do?
Things are shifting from WinPv software over to the Dynojet Power Core C3 software bringing all of the Dynojet products and peripherals under one roof. More tables than ever in this software and most calibration groups & strategies are already supported. You can download it here>> https://power.dynojet.com/api/object...lease/Download
So, as of now only the PV3 is supported by PowerCore. Do you know if they will be adding the pre 2020's?
I believe all 2014-later Canbus tune strategies are supported in the current version of Power Core, the only tunes levels that haven't yet been added are the earlier J1850 (4-pin data port) models and they will be added soon. Make sure you are running the latest software version under Tools>Check for Updates, and update as necessary.

All of the tables are still there, the software hid them. If you cannot open your tune in Powercore you can email us the tune thru our Fuel Map portal and we can adjust as necessary.

What are peoples thoughts on smoothing the VE tables? As an example, if you are in the power area of a table and have one cell with a value of 75 and the next cell is 120 followed by another at say 80. If you had monitored hits while auto tuning and saw the value of 120 was one that had a lot of hits and the others didn't, I would suspect that the 75 and 80 cells need to come up. If the 75 and 80 had a lot of hits but the 120 didn't I would suspect reducing the 120 down is correct. Looking at the graphical view of the tables, I don't see why an engine would take a 15 ms pulse of fuel, then only 250 rpm's later need a 25 ms squirt, then 500 later need 15 again. From tuning other engines (not motorcycle) I see the fuel tables are much more smooth with no sudden large value changes between 2 cells.
So the question is, do folks smooth out their tables or leave the radical peaks and valleys in there? Seems there would be wasted fuel in many cells.
