450cc injectors and E-manage
 

Ok, To start off I can't use my stock ecu ( I have a 92 prelude S ) to chip but I have been told that a P06 or P75 ECU would work. I dont really want to go through all that hassle since I have never done it, as well as my friends in the area. But the route I want to take is the Greddy E-manage since my friend has his tuned on his supercharged H22. Anyways when I get the program Im going to install larger injectors (450cc DSM injectors) but do I have to get a better flowing fuel pump? I just installed a new OEM...and I'm running off a 12:1 ratio FMU with a B&M fuel pressure regulator.

Also, when I install the e-manage and start to tune--- Do I keep the FMU and MAP sensor Check Valve working on the engine or take them off?

E-Manage is not very popular around here.The FMU you will not use as it is a substitute for engine management.Stock pump is fine for moderate boost but the insurance of a walbro is worth the $90.The check valve won't be needed either.Chipped ecu would be cheaper,offer better tuning capability and it's pretty easy to use.

I know but I have no experience in doing that stuff and I talked with Splitime from honda-tech. He told me that since I would have to remap or configure a different ecu to my engine specs might involve alot. So since my friend already knows how to tune with emanage Im going that route. It does the job.
Thanks for the info.

If I leave the stock pump with 450cc injectors boosted around 7 psi whats the worst that could happen? fuel pump give out?

Considering your fuel pump is new I wouldn't worry about it.Good luck with it and post some pictures when your done.

For sure, thanks. I got alot of new stuff to for the setup: greddy oil catch can and an apexi N1 exhaust ...I want to get a video to when I have it tuned and at the track
