Injector size for DA supercharger

"leave the original ECU in place and put megasquirt in the trunk"

i was expecting a more technical answer.
i would like some guy to mess with my car without me knowing what he's doing (and the sense behind his actions)
at least with my RRFPR i can use wide band and fuel pressure indicator to find out how reach am i running

Do you know what injectors does SAAB 9000 2.0 turbo use? what fuel pump?

Why would you leave the ori ecu in if you using mega squirt? If you going threw the trouble of doing MS you would want full standalone setup



when your RRFPR springs a fuel line leak and the car go's up in flames your investments will be gone

I don't work with SAAB but you might find the answer at my forum

He's right on target with 30lb injectors from what I've read. You need to tune your chip (or aftermarket ecu) to control fuel and spark well throughout the range. It's as technical of an answer as can be given without basically getting under the hood with you.  

You can upgrade your fuel pump (there is a thread here somewhere, use search)

I have read that the stock ecu can adjust for 30lb injectors fairly well.

RRFPR is an overly simple (almost "cheater") solution to fuel delivery. While it may work, ideally, you would run larger injectors that correlate to your boost pressure. ~30lbs to 10psi is what I hear from everyone. They will support UP TO that. If you run less boost, they will simply have a lower duty cycle.

Bmwconnect is correct (or as near as I have ever read/heard/seen)
10psi, with a proper tune should equate to ~200hp. Possibly slightly better.

Look into the W.A.R. chip for diy tuning.

The stock ECU can't adjust to 30LB injectors by simply swapping the stock injectors out...You must edit and lower injection constants within the bin file on the chip...I can guarantee anyone that try's to put 30#@43.5 psi injectors in will flood the engine and will foul the lambda sensor and throw a code

I have seen two 10psi dyno runs from the DA SC KIT one at 200whp@10psi and another at 209whp@10psi... Just to give you a idea how much more efficient a turbo is on the m42 @12psi_w/inter-cooler the car made 258whp at vac motor sports on pump gas

War chip or ostrich 2 is the way to go...Both are emulators and both have support but you can do way more with the ostrich 2 at the end of the day

There is a serious lack of knowledge when it come's to tuning these cars I can see

Fair enough. Keep the help coming.

Do you have a stock/modified rom file you could share? I'd like to take a look at it.

I can share the stock bin for the 175 ecu ...Got to pay to play with a pro tuned file though
