Fueling questions n/a '99
Back round:
building a '99 for csp solo auto x. Stock 99 engine recently rebuilt for slightly higher compression. I have MS2 enhanced, i have it installed and i am SLOWLY learning tunerstudio. Mostly been autotuning and messing with timing but nothing crazy.
So i was originally building a supercharged car and i had slowly accumulated a 255 walbro, 725cc injector dynamics, m tuned dual feed fuel rail, and pnp toyota cop's.. I had planned to run e85. So now that my plans have changed and i'm just building an n/a car (want to run e85) which parts should i keep/install, or what is over kill? Also, ive been reading a lot and im still a bit confused on whether or not i need an aftermarket fpr, or i can control the 255 walbro and 725 injectors solely with ms? TIA

Keep:
255 walbro, 725cc injector dynamics, m tuned dual feed fuel rail, and pnp toyota cop's
Yes, that's ALLOFIT.
Obviously, with E85 you need to burn roughly 2/3x as much then normal gasoline or petrol for those brits.
So that's fuel pump and injectors.
Duel feed because... duel feed.
Toyota COP's because they are a very good improvement over miata's stock ignition.
Edit:
You do not need a fuel pressure regulator. NB's already run ~65psi

two more questions which i have been searching and am just plain confused now.. When installing the 725's what am i adjusting setting wise in tunerstudio? Is it more than req fuel and crank pulse? And same question for installing the 255 wally, any adjustments necessary on ms? I lied 3 questions, when cop's are wired and installed all i need to change on ts is the spark from batch to sequential? sorry for all "spoon feeding" but im just confused...

Injectors & pump: Yes, Req_fuel will need to be changed and since you just changed just about everything about the fuel system. Everything will need tuning and tweaking to get it just right. They shouldn't be far off though.
COP: You want sequential, I'm not sure if MS2e has the requirements for sequential. I know my MS2pnp doesn't.
Spoonfeeding: Research research research. Eventually it all starts to make sense and you can move to forks.
