RDX Injecter fuel pressure tuning
 

those that have switched to rdx injectors. what fuel pressure have you set for tuning

Re: RDX Injecter fuel pressure tuning
 

From what I've read, it seems the base fuel pressure is 50psi and tune from there. At least that is according to Xenocron...

Re: RDX Injecter fuel pressure tuning
 

On my personal racecar, I run 60psi. These injectors respond well to pressure from what I've seen..

50-60 will be fine..

Re: RDX Injecter fuel pressure tuning
 

I ran stock base fuel pressure for a typical B series FPR.

I think they would have had fewer/no quirks had I raised BFP.

I would definitely run at least 50 psi BFP on them.

I run mine at 60psi

Re: RDX Injecter fuel pressure tuning
 

I set mine at 55 psi since that's what the rdx fuel pressure is I think


you should be fine anywhere between 50-60psi

Re: RDX Injecter fuel pressure tuning
 

What kind of mpg's are you guys getting with these RDX injectors?

Re: RDX Injecter fuel pressure tuning
 

I haven't got anything better than 30 since I smash on it constantly lol
and I didn't have any others to compare it to I built it with rdx

in the city I get about 18-20mpg freeway I get about 30

I'd be happy with 30's on the hwy. Thinking about getting a set of these more and more.

Re: RDX Injecter fuel pressure tuning
 

I average 28-30mpg city with my h22 hatch. Fuel pressure right now is OEM until I get some time to play with the tune some more.

Re: RDX Injecter fuel pressure tuning
 

on my last dyno I gained 7-9 TQ in primary before vtec.
on a hotter more humid day(20 degrees hotter and much more humid)
i increased pressure to 55psi
flanged out intake pipe to make smooth transition
removed PS

so between those 3 i gained pretty good chunk of torque in low end

Re: RDX Injecter fuel pressure tuning
 

These injectors like ID's really come alive at 60psi and make start to make really good part throttle torque numbers with that pressure.
