i just posted up some tips on this matter in th other thread that morgan started

daniel427ss · 06-29-2009, 04:03 PM

has anyone ran this with a s20g???? i know iknow this turbo sucks but its been decent. the only thing is i can't boost above 21, can this box do it? internal wastegate that is.

thanks for your response (and i read the other thread)...when this rain clears up ill start testing this sometime this week

when i save a setup, it saves the duty cycle to right? as well as loading a saved one?

Yes, if you click read before saving.

Also, it saves on the box if you click write.

If you have a 3 bar map sensor, you can do it. The stock one won't go that high.

also phrozen, is the duty cycle based off the wastegate? wastegate spring? solenoid? or the turbo?

yeah i have the 3bar map sensor, (stg2) i currently have a PIT electronic boost controller(i dont know if ur familiar with it Boost Control+) but never really did good to move the gain n % of i dont remember what else, i only spike 26 27 but then goes back to 21 always n sucks. (this is at a target of 8psi)
ive always wanted at least 25 26.

The duty cycle is the duty cycle that drives the solenoid.

75% duty cycle means the solenoid is open 75% of the time and roughly allows 75% of the full airflow through....

I just looked at it a bit, but it sounds like your wastegate is coming open at high RPM, more than a fault of the EBC.

Ours might do similar things, or it might do better. It depends if your wastegate can handle the pressure. Internal or external gate?

So technically, if you run the stock solenoid and a AGP wastegate (big turbo guys)...we should have the same duty cycles for boost even if the turbo is different...correct?

No, probably not. They might be close, though. The actual numbers will car specific, temperature specific, altitude specific... That's why it learns and adjusts...

internal, how can i know if my wastegate can handle it

Hard to say. You'd have to go by what others have done with that particular turbo and WGA, or try an MBC and see if it holds the boost.
