Fuel System Solution: GReddy E-Manage
Read more about it here: The Greddy E-manage & E-01 Source!
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!

Rep Power: 419 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).[hr]

Rep Power: 419 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.

Rep Power: 0 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?

Rep Power: 0 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.

Rep Power: 419 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.

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.

Rep Power: 0 It's good but the instructions are incomplete... I have it on my car, it's accompanied by the Profect E01 Boost controller... But the Honda computer keeps on overriding the e-manage... Our Honda computer is extremely smart! you would be surprised... Don't get me wrong the e-manage is probably the BEST piggy back system as far as Bang for the buck wise, but It's hard to set-up due to the instruction being incomplete... And Greddy has been giving us the run around for about a month... So...

Rep Power: 0 Has anyone used the e-Manage with the ignition harness to adjust timing? I want to do this, but I've been told that the e-Manage won't work for DIS distributorless ignitions with individual coil-packs. Can anyone comment on this?
REDVIC, what exactly does the stock ECU do to "override" the e-Manage? And what was the workaround?
Any other specific gotchas to look out for?

Rep Power: 0 I am was planning to use the ignition harness later on... But I guess I can't? As far as instructions go... They were incomplete when it came to installation and using the product itself... The chinese intruction booklet was HUGE and it had diagrams that the english version didn't have... The english version was photocopied so??? But the Honda computer kept on overriding it in the fuel management departement... The Honda computer kept on trying to compensate for either running too rich or too lean... Now at this point we are not sure if it is because it was installed wrong due to the instructions being incomplete and the run around from Greddy or it's technically not possible to use a piggy back system on this computer? None the less the OEM computer is very smart... Sometimes (After getting pushed really hard) She will idle rough... But as sonn as she see's boost again sh'll idle normally at 700rpms.
My advise is for those of whom plan to use forced induction... Get a Standalone system... I.E: AEM EMS... would probably be your best bet. They are actually currently going down in price. I am not saying the Greddy system is bad but I think there might be some Glitch's (Because it just came out)...

Email from GReddy:
"That is actually correct. We have found that the e-Manage is not compatible with the new Honda individual coil pack ignition systems. You will still be able to control air flow volume and injector duty cycle, but you will not be able to directly alter ignition timing."

Rep Power: 0 Yup, that's the response I got from GReddy too. But they did mention to me that they plan on supporting our application later on, even for ignition control. They did not commit to when this would be available, or what would be involved (new ignition harness, new software, both, etc.)

Rep Power: 0 My mechanic just got word from GReddy that the new software for the e-Manage will allow you to control our DIS ignition timing. A little too little too late for me -- I'll probably retrofit this in about a month. But for the rest of you, go ahead and get your e-Manage flashed with the latest software and you should be good to go (and the latest support tool of course).
If anyone else gets it working before I do, do post some details.

At least they are doing something for our car. Or so they say.
