Hi,

No matter u use Profec B, SBC, AVC-R or EVC, it should have the duty cycle/gain/offset to compensate the boost spike/creep and obtain the desire boost response. So my question is:

I got HKS EVC V, boost is solid, no drop or overboost, but the boost response is slow. I try to offset to boost curve faster, but not sure what is the correct offset setting, anyone has the idea on ur EBC setup about the boost response?

My setting is:
-3" full exhaust, no cat. Stock WG.
-When I turn off the EVC, the wastegate spring rate is 0.37 bar
-1st setup: I set the EVC mode A in 50%, it should be 0.37bar X 1.5 = 0.555 bar, but actual boost is 0.87bar. Overboost?
-2nd setup on mode A. Offest valve increase 17%, it comes to 0.82 bar, but still not as the desire boost level 0.555 bar.
- I assume more offset value, the lower the max boost to reach the correct percentage. But the offset range is from 10% to 200%, default is 100%. So increase 17% = 117% in offset value.


I really got no idea about the offset value.

So anyone has SBC, what is ur gain value?

AVC-R people, what is ur duty cycle?
