Power Vision Information Thread
So, I guess I'll have to use whatever canned maps are available from Dynojet when my PV comes in next week. Anyone dealt with Dynojet techs for tweeking your tune? I've only got Rush slipons and a Kuryakyn Hi Five Mach 2 Air Cleaner, so nothing too drastic.
Thanks
Thanks!
Or you can verify that you are logging all the channels and do a normal log at any time by just starting the log.
Curious what the VEs do in the upper ranges of MAP/RPM.

I noticed that my rear cylinder spark plug was black and oily. Even the white part in the middle (electrode) was black.
While my front cylinder spark plug was black (dry) but the white part of the electrode stayed white.
I am assuming my front is ok.
Can anyone look at my document. I have the both stock air fuel tables and rear cylinder spark advance.
Thanks
Decel pop should be best addressed by changing the AFR-Lambda value at 20kpa, or 0% TP for non-TBW bikes like mine. I've had some problems with a single pop at the instant of pulling back the throttle, and lowering the DE values at the pertinent temperatures has fixed the issues. After changing to 4" Jackpot mufflers recently I had to add some fuel to 1500-2500 rpms to get rid of some decel pop, and I did that by decreasing (richen) the AFR values in those locations. This assumes you have tuned these areas and the AFR values you are getting are accurate. You could increase the VE values instead, but I would rather get AFR's tuned-in correctly, then adjust the AFR values to reflect what's really going on.
IOW, if you have 20kpa set to 14.6 (1.0 Lambda) at the location causing the popping and the VE tables are set properly to give you stoich at that point, changing the AFR-Lambda value (lower) will give it more fuel in that area and the VE and AFR values will match.
When I first got the PV I was liberal about changing the VE-table values to make small adjustments, but that was before I caught-on to how they actually work in relation to the AFR-Lambda table. The idea is to establish the AFR you want to run throughout the RPM/KPA range, you then adjust VE's to match these values. It's easy with the Pro procedure and wideband sensors, but you can't do it across-the-board with Basic.

I would either call or email Fuel Moto and ask them. I am sure they should be able to set you up.
