Power Commander V Secondary Fuel Module
Product Overview (Note: Product Coming in Late Summer)
Most of today’s high performance, four cylinder Sport Bikes have two injectors per cylinder. The Power Commander V connects to 4 of those 8 injectors. In virtually all cases the PCV’s +250% / -100% fuel adjustability allows more than enough adjustment for all but the most radically altered engines. However, we recognize that there are people building heavily modified engines (extreme big bore, turbo, etc) that may require the adjustment of all 8 injectors.
Enter the Power Commander V Secondary Fuel Module. The S.F.M. connects to the upper injector rail using OEM connectors. From there, it is only a single cable connection to the PCV. Once connected, you will be able to adjust both upper and lower injectors by as much as +250/-100%.
If the gear position input is connected on your PCV you will have the ability to adjust all of the injectors on a “per gear” basis (a complete map for every gear) as well as the ability to map each injector separately. That gives you up to 48 complete maps!
There will also be a "basic" mode that allows you to have a single fuel table that simply puts the requested fuel change in both upper and lower injector modules at the same time. For those of you that have modified engines that require more fuel than 4 injectors can provide, but do not need the complexity of mapping each cylinder and each gear separately, this setting is for you.
In addition to the increased fuel adjustability the SFM provides, it also allows for the use of the Dynojet Quick Shifter sensor on 8 injector bikes. On earlier Power Commanders an Ignition Module or Stand Alone Ignition Quick Shifter was necessary to use the DQS on bikes with 8 injectors. Now, you can have both added fuel control and shifter functionality at a very low price.
Projected retail price $249.99

48 complete maps? Go ask your local tuner what the charge will be to do that

Their head would explode when you asked.

Somehow I don't think that is geared to the local tuner. I have only seen one or two people even bother adjusting fuel per cylinder. It takes more than just a standard wideband lambda sensor in the tailpipe to do that. A multi gas analyzer would help with that.

How many people here have had a PC mapped per cylinder?

Kinda sorta.

My Akra had bungs in #1 and #3 and NOT donwstream of the collector sniffing all 4. I auto tuned off both bungs but not at the same time of course, then made seperate maps for 1&2 and 3&4. They were pretty close the same. I think later I will average them out and just go with 1 map for all 4 because they are so close.

You wouldn't get 48 maps made n the dyno.... you'd at most map each cylinder (via putting a bung in each header pipe and mapping each one off a base of whatever the 1st one mapped out at) and then with those BASE maps, use them again, for your gear maps, there's 24 maps done. Then, you would then auto tune at each track or where ever via the usual 02 sensor in the lead pipe (mix of all cylinders) to get it spot on for each gear. But then that would have to be done with an average of the maps as you wouldn't be measuring each cylinder................... unless you wanted to auto tune every cylinder for each gear at each track................. jesus..... haha

Or you could start selling your sister to pay for 48 maps. haha
