As much small problems as i've had with the Emanage, i think a good tuner can take out most of the minor probs but that takes money and time on the dyno, the rest is the unit itself and it's compatibility with 550cc injectors. i had it on my car no more than 3-4 months. The Throttle response was bad, especially through traffic. i didn't like the overall drivability. But it was also tuned only 2 times, before i decided that a standalone was my best option. They couldnt get the fuel rich enough at WOT with the emanage. It also set off the Check engine light sometimes, causing my ecu to go into a limp mode. Personally, i think it doesn't control 550 injectors well. i've heard 440cc are better with the emanage. That's why i'm selling mines now

But whatever your gameplan good luck

let me know your results.

@my

I never had a problem running 550 cc even pretuned. I found in my case that as soon as you fill in the starting and ending injector size that the e-manage controlled them pretty good.

but as my post states im looking to find out about anything greater than 550 as I ran those successfully.

I believe you will get a variety of responses here, primarily due to the varied nature of what each of us finds "acceptable control". I did not think the 550cc nor the 440cc acceptable in part throttle and no matter how much I tuned (I tuned night and day for months), the car never was clean like stock when not in boost. I drive often in traffic and below 20% TPS, the larger injectors were not able to have the pulse width required for smooth I/O transitions.

I stuck the stock units back in, pulled the aftermarket high flow/high pressure pump and car drives flawless. The pintel design for the 440cc and 550cc (even with diffuser) is designed for a wide spray pattern, which does not agree with the way Honda designed the fuel aim, which use a very narrow, squirting designed.

If you go with larger injectors, expect poor performance below 20% TPS, above that all is good. That has been my experience.
