AEM electronic boost controller location

In the generic setup for AEM boost controller (EBC) it looks something like this. Obviously I'm using the 2nd method with the T and the external waste gate. My question is, does it matter where I put the T split?

more specifically......

- Can I put the EBC near the WG with two 6" lines, and a long line back to the intake manifold?
- OR have the electronic boost controller up near the firewall with with two lines running to the EBC

I can't find an answer for this; does the distance matter or can I put the EBC anywhere I choose? (ie - EBC & Lines in the fender)

Grumpys93 seems to have made some friends!
I would believe that because this is a sealed system (sort of speak), Pascal’s law should apply which is force is exerted the same in all directions. Unless I am just trying to sound smart and I’m dumb. But I do not believe distance changes anything, but having the air flow through the intercooler and other restrictors would. If it did make a difference it would be very minimal.

Yep, that's what I was thinking. Whether it was 3' or 15' of hose/tubing the PSI will be the same.

My harness is being made to fit mine up under my dash. My harness builder is fairly well versed in boosted performance applications and didn't seem to mind. All to say that mine will be a remote location with plenty hose length to contend with.

I wish I could offer you something more scientific than that, but I'm not really to that stage yet.

I asked my tuner and he said the shorter the hose the better. Because you want to maintain pressure and have precise on/off points. But for all I know there is a setting in S300 for WG lag to address the delay in the EBC reading the manifold pressure vs. the BOV pressure.

But at the same time I can see using 100' of hose being an issue. But for the distances I would use (no matter what route I take) it's negligible.

turbo90accord is cool... so far.
Shorter distance allows for faster boost response. It takes a lot longer to vent 25psi from a 10 foot hose than a 1 foot hose.

Shorter to the WG I'm assuming.
