I don't recall seeing anyone post recent info about using a Dynatek CDI. Specifically, what Dynatek item # are you referring too?
I recently added a HMF Swamp to my '07 700 and have been using a Dynatek FI Controller since I already bought that FI controller a couple years ago. That Dynatek FI controller uses potentiometers to adjust L, M, H throttle fueling so it is not exactly like a HMF FI controller or EHS FI controller which has the ability of maps. I knew I was always running rich but was too hesitant to turn down the fueling for fear of running lean. I have been told, and read elsewhere, that using a spark plug to understand FI fueling is not the same as in carb machines, so that may be a wasted effort for FI... I'm going off of other's knowledge here as I don't have expertise in that area.
It is only when I followed information from user @RockTaco to get a 4-stroke AFR Wideband installed to know what was happening with air/fueling ratio from sniffing the exhaust. He had told me to either pay a shop to insert their sniffer to measure the exhaust ratio for a one time $$ and assessment, or to get that Wideband installed so I can always know what the ratio is and make adjustments representative to what I observed on the meter while under load. Under load kind of being key since I ride anywhere from 6000' to 12,000'. I try and adjust based on the meter running while at 7700' which is where I live. Going up in elevation will only cause richness so that is not a big concern versus running lean. I realize the elevation part of this is not something a lot will have to deal with but elevation also played into the factor of trying to get my bike tuned properly and get power back.
With the rich issue going on, I also ran into another issue this last summer which I originally thought was related to my fueling problem. I was experiencing cutting out while mostly at medium throttle but it also could have happened at H or L throttle. It is only when I noticed the R light on the POD lighting up that I remembered reading about that happening. Some research on GC and I was able to find info related to the Neutral Assembly Switch (sensor) going bad that caused my cutting out. I recently replaced that switch and haven't experienced the cutting out since but I haven't put too many miles on her yet, only about 20.
Additional to fueling on the '07 700 Grizzly is the ability to adjust via the "POD MOD". This is probably not your issue though as I believe the POD MOD single adjustment is a global adjustment for all ranges of throttle input: L, M & H.
I'm not convinced any of this will help you other than the part about guessing at air/fuel ratio is not an exercise I was able to get right without the proper tool(s).
