Welcome!

I’m not sure on the dynatek.

Dust devil is familiar with them! I’m sure he will stop by soon

The Dynatek F.I controller is simple & works great...

To find the fuel curve that works...

set the Lo,Mid & hi trim pots to center/ 0

Start the motor if it don't Idle..turn Key off, turn the Fuel curve pot one click, repeat...until the motor starts, Idles & you can throttle up without stalling...

Once it start,Idles & throttle up..then adjust the Lo,Mid & Hi pot to fine tune...!!
