HKS EVC III (or EVC 3)
Here's the feature list for the EVCIII:
- 3 boost settings: low, high, and manual. Low goes up to 1.0
bar (1.0 bar is 14.7 psi), high and manual go up to 2.0 bar.
- Digital boost meter, reading in bar only. Updates about 2 or 3
times per second.
- Boost is adjustable in one-hundredths of a bar (.01 bar/.147 psi)
- "Offset feature. Alters actual boost curve of turbocharger. This
feature gives you an adjustment window for the self learning boost
adjustment mode." I don't really understand what this is or how
it works.
- Scramble boost feature: allows you to increase boost above low/high
settings at the push of a button, for a given period of
time. You can specify how much boost increase you want and how
long you want it to last. There's a connector for an external
switch you can mount anywhere.
- Boost warning feature: you can set the warning threshold to whatever
amount you want (up to 2.0 bar) and if boost exceeds that level the
EVC will blink and beep, and will instantly return wastegate
operation to stock levels.
- Switch-configurable wastegate type (integral or external).
- Serial port: supposedly for interfacing with other HKS units
- Fuzzy logic: supposedly manages the wastegate better than straight
digital logic.
