rrfpr with e-manage

[MarckGlanza]

hi ppl do you need a rrfpr if you have e-manage ultimate thanks

 

[goldenvtr]

you dont need them but depending on injector size you may want one to set the injectors to the requierd pressure - as i have done with the 550s to maintain a decent idle

cool is that if i change the injectors at all or what size would i have to do it thanks

I dont get that, i run 550's at stock pressure with emanage blue... my idle is perfect!!

 

[goldenvtr]

the stock pressure for the 550s and for the 295s are diffrent, im sure 550s have a higher stock pressure on teh rx7 so if you running stock starlet presusre you wont be getting the full 550cc IMO the rrfpr will make the most of your injectors.

550cc injectors on standard fuel pressure will still flow a LOT of fuel? e.g unless you're going for 400+hp you should be just fine. Upping fuel pressure will screw with the fine mixtures e.g idle, off throttle and the tune will suffer as a result... emanage is limited in how much fuel it can dial out.

it adds another point of adjustment, which is always a good thing
