Will RC 440cc injectors work with stock ECU

I have a 03 350Z with a Procharger and FMU set up.

I just inquired some 440cc RC engineering injectors.


Can I just install them without getting a reflash. or and external injectoe control.

Will the stock ECU adjust for the 440cc injectors?
Will the car run ok.

PROS/CONS.



Thanx.

 

im pretty sure you will need to retune, but if you dont you will just run really rich.

 

Procharger on stock ECU control FTW!!! Stock timing + Boost FTW!!!!

You need to find a way to rescale the injector and the ECU wont do that without a reflash or an EMS. You'll be fine in close loop but once you hit boost then SUPER RICH brotha...

 

i have rc 440's and ss box. works great!

 

Just get a reflash. You want to delete the timing advance map anyhow.

 

You also may consider a piggy back EMS, which will give you some tuning options.

I have 440cc injectors and a Greddy E-manage (Blue I beleive) that came with my Greddy TT kit, but have never been used. I can cut you a very good deal on the injectors, the E-manage, or both of these. EDIT: The injectors are RC Engineering.
If you are interested, PM me.

 

Reflash will be one of good option in that case.
