injector staging?
 

I've read the manual for my e8 but I just can't seem to figure out where to set the staging bar for my s4 na.(s5 mani ports open, 550cc primes 720cc secondaries)

It just seems like I'm either way way to rich(car floods at low rpm) or it's like the secondary injectors aren't even there.

Your injectors are large

4 550's would be easier to stage unless and unless your trying to run a dry nitrous system, you aren't going to make near enough power to warrant that much fuel.

Hell what I would do is get a set of 1K CC injectors and not run staged injection that is just run 2 injectors in the primary location.

They would be plenty controllable by a haltech, easy enough to tune and would eliminate much complexity, and support your max power potential with a street port NA.


But here's what you should do, stage when you get to 75% duty cycle on the primaries at or shortly before red line.

Also, another thing would be to point out that it may be better for you to tune the engine using TPS load as your main load source, and stage your secondaries around the 25th bar, and you'll be able to have map sensor blend to maximize corrections.

wow
I found what I needed.

The only problem I am still having is getting the bottom end to not hesitate(1-3k). I leaned out the text map a lot but I think I just need to lean out throttle pumps now

+1 egg-zach-lee what i would have said
