How would DBW alter SC instalation or operation?

 

The biggest issue with the SC kits is the use of a returnless fuel system. Which makes addition fuel enrichment by a FMU impossible.

No extra fuel = No SC

 

Has any one heard of someone converting an 06 back to the wired throttle system?

 

I'm still waiting to hear back from some of my sources so that I can finally put in the turbo set-up I have.

Back dating to the earlier system is easiest by buying a 00-05 car.

 

Can't you overcome this issue by making a returnless fuel system?

Also, I thought the MAF/MAP issue was the "long pole in the tent"?

 

I wouldn't expect a supercharger/turbo to be available for the MY06 until early 2007. Yes, Comptech is advertising that they are making a supercharger for the MY06, but in reality they haven't even started. They are still working on the supercharger for the MY06 Civic Si. Once that kit is done they will start working on the S2000. Once they've started working on it you'll know because they will start posting pics on their website, like they've done for the Civic Si.

 

The 06 has a returnless fuel system. The fuel pressure regulator is in the tank.

To use a FMU (like both Comptech and Vortech SC's) you need a return type fuel system. As the FMU installs on the return line to increase fuel pressure in boost to add fuel.

There isn't a MAF sensor on the 06, but there is a MAP sensor.

Hiding boost from the stock PCM is what Comptech does with the ESM and Vortech does with 1 of there black boxes. It's known as a MAP clamp. Which blocks a boost signal from the MAP sensor from going to the PCM.

 

My bad...I confused the term. How difficult would it be to convert the system to a return type fuel system?

To make sure I understand this correctly, the FPR used to be mounted on the fuel rail right? This made it possible to upgrade to something like a Comptech FPR, right? Also, because of this change, PY aftermarket fuel rails are incompatible.

From what has been posted on the Temple of VTEC forum, the MY06 S2000 and Civic Si have both a MAF and MAP sensor. This is something that is apparently kicking Comptech's butt, which is why they haven't been able to complete the supercharger for the MY06 Civic Si yet. Apparently they are going to use some sort of piggy-back system, but that isn't going to resolve all the issues. They MAY be working with Hondata to resolve whatever the other issue(s) is(are).

 

would this even be worth it if honda decides to ax s2k productiion as 07 last year?
