Just picked up an HKS VPC & GCC controllers for my
87' with stock injectors, turbo, and auto trans. Only mods at present are intake, downpipe, and exhaust. Only have the installation manual for the pressure and temp. sensor. Also, have the VPC harness and stock PROM chip for my application. I need the correct internal dip switch settings for the VPC + GCC computers. Plus, correct harness and wire hookups for the components. Tried contacting HKS USA in Cal. but always busy and they NO longer carry the manuals. Due to the VPC being "old technology" and been replaced by the new Pro-FCON. Any HELP would be greatly appreciated!

You're not likely to find anyone on this site running the HKS alphabet soup. Check supramania.com - you'll have better results.

Just out of curiousity, how much did you pay for all that?

I realize HKS products are pricey. I picked them up for $450 and in like new condition. Thanks for the tip, I'll check out the supra-mania site.

I was afraid of that. For a few more dollars, you could have picked up a MaftPro, which does WAY more than the HKS alphabet soup, is upgradable, features boost control, timing control, AFR adjustment, use in conjunction with a wideband o2, speed/density (no AFM needed), etc...

Yep. Some of the local Supra guys gave me the low down on that setup after the fact (purchase). Live and learn, I will definately be doing more research in the future for the next stage of the project. Can't afford these "pricey & limited" choices.... Hehehe....
