Just a quick note on how I understand the LLoydz timing wheel came about and how the PCV or other power commander maps for ignition timing advance work.
i was told that the software for the Victory ECU does not allow for ignition timing advance below 2,500 rpm. If you design a power commander map and input some ignition advance all the way through the map, you will still not get any advance until the engine reaches 2,500 rpm, which on my bike is around 75 mph or so.
So, LLoydz came up with the manually adjustable timing wheel to allow spark advance at all points in the motor’s operation. However, it’s a fixed amount of advance, and you set it up and lock the advance in place. I set mine up before I put the Lloydz wheel on the bike.
Now here comes the rub, if you are using a power commander and have some advance in your map. Let’s say you have the LLoydz wheel set at 5 degrees advance. And the power commander map you are using is set for 5 degrees advance. All is fine until you hit 2,500 rpm, then the PCV kicks in an additional 5 degrees advance and you now have 10 degrees advance, over whatever the original ECU setting might be.
It’s very easy to grossly over do the amount of advance you put into the motor.
These motors are designed to operate over a large ambient temperature and pressure range, as well as humidity levels. So, you can squeeze a bit more performance out of them with exhausts, cams, power commanders, timing wheels etc. But you have to be very careful about what you do, and add these improvements a bit at a time, and monitor the results. You might have to go backwards on some things to get the performance or operation you need for the environment you operate in.
It’s harder for you, as you have purhcased a bike with all the mods done, so you haven’t the advantage of trying one thing after another and seeing what results each mod have given you. I see some minor disadvantage to the Lloydz wheel on my bike, but overall the advantages outweigh it. Everything is a trade off, as no engine will run perfectly at all altitudes, temps and pressures.
So, start off with your timing stuff, review the map that is installed on your power commander and do what needs to be done there. Dynojet offers a free download of the software to run the map, and if you have a pc laptop you are in good shape. You just hook it up to the bike, turn on the ignition and go from there. A little more to it of course, but the software. and instructions are pretty good. The most important thing is you need to access the map in your Power commander and see what advance you have programmed in there first off. next you check the timing wheel setting. I’d also talk to the folks who supply the cams and ask them what they recommend for ignition timing, as that will have a lot to do with it also. Exhaust installation will only have an effect on fuel delivery and adjusting the fuel to take advantage of the freer breathing engine. Power commander also has to be mapped to include the modified cams and exhaust. I assume that has been done, but once again, you will need to check. I would think that someone who had done all that work, would probably have dynoed the engine and tuned it and mapped it to provide the optimum in running, however, the LLoydz wheel might not have been installed first and so it hadn’t been accounted for.
Sorry this got longer than I had intended, but you are going to need to be careful gathering all the information before you do much of anything.
