It a good solution for a turbo upgrade. You have to read into the instructions to understand what it's capable of.
Basically it allows you to control the air/fuel ratio for up to 3.2psi straight out of the box for about $300. Although this is not it's true capability. Use a laptop and the software to control the air/fuel ratio for up to about 7.35psi of boost for an additional $120 (although I think you can just make your own harness and save a bundle). That is if the stock injectors are capable of that much flow.
Not done yet though, buy the injector harness and the ignition harness (again, you might just want to make your own) to be able to control the injector pulse width and to advance or retard the ignition timing for another $70. This will basically allow you to run at 100% duty cycle of the injectors. If the stock injectors max out, then simply replace them for higher flow ones and de-tune the fuel flow for lower rpms'. You can de-tune up to 50% of the flow rate, so if you get injectors that flow twice as much you can tune the engine to behave rather normally at low rpm's. Sweet huh? The stock injector size is rumored to be around 75cc's (not sure though, anyone...). Doubling that would give us 150cc's. Multiply that by four and you get 600cc's of flow. Although I don't know at what fuel pressure. Anyone?
We're not done yet though. If we've exhausted the fuel delivery capabilities of the stock fuel system then we can add on another injector or two and the GReddy E-Manage can control them. The only thing is that you should buy the E-Manage pressure sensor for $99 and harness for $29 (again, the harness could be fabricated). Then you can tune the extra injectors based solely on boost from the extra pressure sensor. Nice, huh? Before resorting to the above step I would try increaseing the fuel pressure and simply living with slightly richer lower rpm's. You could also just get bigger injectors in the first place though.
If someone knows the stock injector flow rate (in cc's) at a certain fuel pressure then let me know. I also need to know the fuel pressure that the fuel pump produces. I don't know if it's variable or not? Anyone?
Anyway, this is looking to be the best bang for the buck with regards to the fuel system issue! I know that one of the red concept 2002 Si uses this system with a turbocharger and it works!

Haha. Yeah, one other thing I was thinking of was how the hell to make the air/fuel pressure ratio stable when the blow off valve activates during closed throttle when the turbo is making boost. I think I know now though, with closed throttle air can't get in anyway, so the boost escapes through the BOV and injecting fuel into the engine doesn't really harm anything. You'll just be running rich. I don't think even this would happen though since the E-Manage hooks up to the air flow sensor. Less air flow means less fuel. Yeah, that shouldn't be a problem.

wow nice post. if im not mistaken you dont want injectors going at less than full cycle (im probably wrong on this one).

Wrong... you never want to have to go to 100% of your duty cycle. Best way to do it is to plan to be at about 85% duty cycle at the highest boost level you'll be running. If you hit 100% frequently as you would with this setup, you'll clog and burn out your injectors very quickly.

If you haven't lifted the head off of the block, you're not racing fast enough.
Yep yep. Very hot IMO. It should work with almost any EFI. Our application isn't listed specifically, but we should be able to hook most if not all of the sensors up to the unit and have them function. It's just a matter of finding out which ones are which with a multimeter.
What about the profec e-01. Anybody think it is worth the money to use it with the e-manage? I'd rather have that controlling the e-manage than using a laptop in the car and it also takes the place of a boost controller. I was originally going to go with the profec b-spec for a boost controller, but I think this is just a better self-contained package. Any opinions?
I emailed GReddy asking them if using the E-manage is viable enough just to make sure. I let them know that it was returnless as well as linked them to some threads. I'll post what they have to say. Hopefully they will say something.
Originally posted by Grey The profec e-01 is nice, but it's kinda expensive. Plus I kinda want a stealth look and I already have a laptop I can use. It is nice though.
I hope you get an e-mail back from them. If they said yes I'de be overjoyed.
Well, I emailed them yesterday. The emailed me back asking me what car. I forgot to tell them it was for the 2001+. So, they didn't outright say no yet. And they at least knew I was talking about using it for a returnless fuel system. We'll see what they say with respect to the civic.
Yeah, the Profec e-01 is kind of expensive... but it's use as my boost controller would absorb some of the cost. I'd pay the extra for a tight little unit though. I don't know how pricing will exactly go with me. I've already started my buying process.
"I have seen our e-Mange used on the 01-on Civics with a bit of success, so your vehicle should be no different. The e-Manage simply adjust air flow volume and injector duty cycle so it should have no problems with your returnless fuel system. "
