Hey!

I installed a HKS EVC 3 a while ago, worked perfectly, but now its started to act weird:

When the EVC is ON(i have no probs when its OFF) and it starts to build boost its building up in waves, not linear, and backfiring some, example starting with zero boost and then full throttle, in BAR:

0.0 0.2 0.3 0.4 0.35 0.5 0.45 0.6 0.55 etc. etc. up to about 0.9 bar of boost.

Ive checked all the vacuumhoses and i cant find any leaks, but i might have just missed it.

I have not done the turbo-selflearning procedure with the EVC since i dont know how to start it. Also, this problem arrived some hours after i started running higher octane fuel, using octane booster.

What do you think?

does it make any beeps after a while when this problem occurs? if so just fiddle with the wiring a little bit, one of them sounds loose (i had this problem). do the self learn too, it should help. the manual is online

      I know people cry at the price of the Getrag 12-14k for a conversion now, but it really is a nice mid point. Not going to get change from 10k on a gearset installed.  $30k++ for sequential.   I know you run the risk of a damaged used one and parts are hard to get but as a street car gearbox its really hard to beat. If you enjoy a more traditional manual, its the choice no question.
