i take it you don't have the O2 censer. best way would be to get to a dyno and have it tested and set by the teck.

i contacted Dynatek
We do not have an ECU/ignition replacement available for this engine. However,
we do have available our Fusion ignition and fuel control system, which
requires a functional factory ECU to work, as it is a piggyback system.
The Fusion will allow fuel mapping changes be made on a chassis dyno, as we
currently only have a stock map available, or, by using our optional Dynatune
(autotune kit) which will create a fuel map as you ride. Timing adjustments
are possible, although historically, the 700 has not seemed to respond well to
such changes. Timing changes should ideally be done on a chassis dyno to
prevent engine damage.
The Fusion for this application has part number DFE-16-033. More information
on this system is available on our website by entering in the make, model and
year machine you have at the top of our home page. The next page will take you
to the part number and there you will find a link to the installation guide
If you need any further assistance, please let us know.
Thank you,
Larry Nelson

I contacted them as well, Kind of shitty that dynatek has so little support behind there product, even if it is a few years old.

hooked it up to computer, has 3 maps preloaded,
Map 1 stock exhaust and filter
Map 2 slip on and stock filter
Map 3 Full exhaust with stock air filter with lid removed.

Please find attached the DFCA-32 installation guide for your review and files.

The FIC will only allow for fuel mapping changes and has no ignition
functions, such as timing curve control or rev limit extension.
At this time, we have no fuel maps available, other than for a stock engine,
so the FIC will need to be manually adjusted for the best performance.
Set the Base map to #2 , and place the Low, Mid an HI pots to zero, or at the
12:00 position. With the engine at operating temperature, adjust the Low pot
to achieve the best idle quality and initial tip in throttle response.
Next, in an area you can ride at moderate speed and load, adjust the Mid pot
so the engine runs smoothly in the midrange throttle opening.
Next, in an area you can safely achieve wide open throttle for 5 to 8 seconds
at a time, adjust the Hi pot so the engine pulls strongly at WOT with no surge

or hesitation.
Once completed, this would end the adjustment process.
Thank you,
Larry Nelson

i just want to do the big 3 lol. dynatek makes good stuff, disappointing how little info there is on this FC.

gonna try it out, once i get my exhaust, if it doesnt work it only cost me $100 and will resell.

wish there was more info on this or someone who could chime in who has used one.

going to try contacting dynatek again and see if i provide them with the maps, setting on the FC if they could help me out further.

so im looking at the maps i have on my dynatek FC compared to the power commander maps that i downloaded for the following mods, seems like the PC5 maps are the same as dynatek map for similar mods.

im not seeing any maps for k&n though... will this be ok?

Also the dynatek FC has an option to import Power commander maps, and have added the PC5 map to position 2.

Full exhaust
stock air filter
with lid removed
