Blue and Black.

They alter the fuel and ignition maps for boost.

Black is cali smog legal

Blue is not.

92-95 only.

Can be used on the 96+ but not legal in Cali

 

so what exactlly do they do ? i mean that doesn't say anything. then why don't i just boost 10.

Because they are designed for the 7 psi that the factory turbo kit is made at.

 

i think the blue box control my fuel. when the blue box read boost pressure it raise the pressure in the fuel system. but i don't know how it has control over the fuel system other then contorling the injector. the problem is the injector are opening max at about 7 to 8 psi, so you can pust it anymore unless your planning on running lean. i don't don't i'm just guessing. but dose the vtec work with the box, i hear they cancel the vtec.

 

The GReddy kit comes at 5.5 psi. The blue box can be rewired to work on the P2P. And no, it doesn't cancel VTEC. There's a website that has the diagrams for rewiring everything. I'm having a brain fart, though, and I can't remember it right now.

 

what's a p2p?

6G Civic computer. Because you were wondering if the guy would be able to install it on his '96-2000 Civic, right? He will be able to use it.

 

Oh yeah, the Edelbrock kit is 7 psi. and Greddy is 5.5 thanks.

Is this supposed to be a serious answer or what?

 

the greddy blue box is a little device that basically throws the injectors into open loop as soon as the MAP sensor reads boost, and basically keeps the motor nice and rich under boost so you can stay safe and keep your motor emissions-friendly.

Now, what some people (like me) do is up the boost a few pounds to lean out the A/F ratio a little bit so that it's 12:1 under boost, as opposed to the 10's under boost at 5-6 psi.

I'll be running 8-9 psi on a stock fuel system shortly. Dyno sheets coming soon.

BTW, I've pushed it to 12 psi on stock everything and only gotten detonation in the upper RPM due to stock timing.
