thats all.
I have control over the ignition map as well, I can retard timing per PSI of boost I'm running. If you've ever used Crome, Ghettodyne, Turboedit, ect that should give you an idea about what I'm saying.

i know there is a VW part that you can use for the electronic 1-way valve but i have to remember the part number. they are like $10 at the dealer and can hold ~35psi,much more than what 99% of people need

EF's are the ---- in camo. and is that an Si seat in front of the tires in the first pic??
I'm running an HX35, the king of all junk yard turbo's ...so my 6~7psi external gate spring is plenty for low boost. But I see what you're saying about the smaller junyard turbo's.

The honda/acura PCS/ECS i'm refering to can be used the same way as your 1-way valve....

No those are 92-95 seats...I do have a mint 90-91 Si seat in the shop tho

What if you're running a VTEC engine ?.....

The point is you don't NEED different maps for high and low boost. The ECU knows what it see's above WOT, be it 1psi or 20psi. Most aftermarket EMS' and "chipped" factory ECU programs know how to compensate for different levels of boost, mostly just due to the nature of how the sensors feeding the ECU work. So long as you don't run into the mechanical limitations of those sensors, and have taken the time to properly tune the entire boost range you are running.....there is no need to switch to a different fuel/ignition map just because you're running more boost.

....Unless you run into detonation in the higher horsepower range( and need to switch to a different fuel) of course

Great write-up. This is how it should be done. Picture(s), diagram(s), and part number(s).

Great job of encouraging him to post more tech up, guys, it's hard enough to browbeat him into posting to a forum where he's understood and appreciated.

If you have zero ------- clue about how a standalone works you need to read the stickies in the Engine Management forum, get the ---- out of this thread.

Reread the original part, Chiovnidca, he says where and gives a part number, too.
