I can't figure out my BC for my 93.5 mkiv tt auto, I tried putting it back to stock and it hits 11psi and tapers to like 7, but once in a while it hits 19+ psi

If someone would be willing to help I'd cover lunch or dinner...If you drive out here I'd toss you 20 bucks too.

Shouldn't be too hard its already got the wiring done and its in my dash I just need the vaccuum hoses delt with.

Its a HKS EVC EZII

Thanks.

I have the HKS EVC5 which is the same BC with additional display. I had similar problem as you do. Its hard to get it running initially. First, make sure you select the (swing vale or what not) valve correctly on the BC. And, follow the instruction to reset the BC.
