thanks for the offer 
i’ll be converting and chipping the ECU myself. It’s been something that I’ve been wanting to learn and research about for a while now.
Yeah, I’ve been finding good articles on pgmfi, saving them, printing them, organizing everything neatly in a binder like a damn portfolio, then learning all the shit while sitting at work. 
yes, you need to add 1 extra transistor to make the 4 wire work.
check which board you have because no one likes to add rm11
i personally would leave it alone and when you chip it, disable closed loop and the o2 heaters, and tune part throttle with a wideband. If your in vac and have minimal throttle opening you can lean it out and get better mileage than stock, but i guess that depends on your project
