Thnk you very much.
You can just change two constants in the sketch and perform the tune procedure.
But i highly recommend to use the version 2 of the controller https://www.hackster.io/sfrwmaker/soldering-iron-controller-for-hakko-907-v-2-fc75d7. :) The schematisc support several types of the soldering iron and lcd display is easier to solder.
To use common anode led display, probably, you first need to change the schematics, i suppose. As to source code, you should change the symbol codes. To use smaller ring you should rewrite the sketch, because the current version expects 24 dots per minute.
There is power limit (line #946) in the sketch to prevent short cirquit activation of the power supply. You can increase this limit up to 255.
Unfortunatelly, the hakko 907 iron handle has big resistance and it cannot heat quuckly. I would like to reccommend you hakko t12 soldering tips and fx9501 soldering handle. I have made another soldering controller for theese brilliant tips or you can buy the stm32 based controller from taobao.
