PCV with Ignition Questions

I installed a PCV with Ignition and Autotune. I have been fine tuning a map and the bike runs really good. I was playing with the Power Commander software and found where you can have different maps (Fuel and Ignition) for each cylinder or for each gear or both. Does this work on the VV and has anybody setup multiple fuel and ignition tables?

I have been asked to perform custom mapping utilizing ALL of the tunability within the PCV.

OK, so lets relate this to a V-Twin.

#1...a seperate fuel map for each cylinder for each gear (12 maps)

#2...a seperate ignition map for each cylinder and each gear (again 12 maps)

WOW...I can't imagine what I would have to charge!! Utilizing the auto-tune obviously would cut the time considerably. The main reason all of this adjustability is built in to the PCV was for the road-racers's needs for different maps for each gear to get the most out of their engines at all of the different speeds seen on a road course.

To tune each cylinder you would need two wide-band sensors, one in each primary tube and a 2 channel module.

I have made a few custom maps on V-twins in the past and have found some differences in the air/fuel ratio needs for the 2 cylinders, but I have not performed individual gear mapping as of now.

Racnray,
I touched base with a Dynojet tech and as you said, we would need two O2 sensors (At-300) to tune for each cylinder. I have the AT-200 so that's out. He also indicated I would need to tap into the gear position sensor and route that to the PCV. The autotune would adjust each table for each gear. Not sure it's worth the effort. I was looking at the software and found that and thought it was interesting. As always, thanks for your response.

Combat, Thanks for the info. Planning on running the same PC setup over the winter and will also stick with one sensor.

I think on a liquid cooled bike the benefits of independent cylinder tuning would be not such a big factor as an air cooled bike where it's a pretty well known fact that the rear cylinder runs a bunch hotter (+15% or so).

If you tapped into the Gear Position Sensor where would be the best place? In the manual there is a Gear Position Switch Lead on the left side near the battery and a Gear Position Sensor Lead right behind the battery near the rear fender. What wire should be tapped into?

The wires coming from the Gear Position Sensor are Blue, Green and Black. They plug into another set of wires and those are Green, Light Green and Black/Yellow. Anybody?

whoaru99,
I contacted DynoJet and they were the ones that told me I had to tap into the Gear Position Sensor. I asked which wire and they could not give me a wire or color. I'm looking at the 2009 VV Manual on page 16-108. It does list resistance values for the Blue and Black wires. Based on the attached file I'm thinking wire #2 or Blue. I'm hoping no difference between 2009 and 2010 in that regard.

Thanks,
Frank

I think either blue or black would work...but the PC-V manual seems to indicate tying into the speed sensor so I don't really know the direction the gear position thing takes you.

Whoaru99,
You are correct regarding the speed sensor. According to the documentation the speed sensor settings are suppose to come from DynoJet already setup for stock tires and gearing. When I looked at the speed settings in the DynoJet software it shows all zeroes. Does anybody running a PCV have values listed under their speed calibration settings?

Thanks,
Frank
