HKS EVC-S
HKS no longer has a USA headquarters, only two master distributors for the territory. You can still request for technical information from HKS dealers but typical response time is 72hours. The EVC-S should show "Set" with either an "A" or a "B" directly below it. Then next to it should show your target boost setting in either KPA or PSI. Using the small switch should show what the target boost for each setting is currently configured to.
Its been a while since we have had to mess with the HKS EBCS but they work well when properly utilized.
