Gotcha. A couple questions:

1. What's your name?!

2. What year is your 930 and describe what mods you have to the engine.

3. Hopefully your CIS engine is already well tuned without using a lambda system in low/mid RPMs/boost and you're simply looking for additional fuel from 5k to redline. If so then most likely our systems can be similar.

My '87 is currently set up with:

Short gears, K27/29 hybrid turbo, Garrretson half bay intercooler, stock 0.8 bar wastegate spring, RarlyL8 headers and muffler, adjustable WUR, and a simplified CIS system. My stock '87 lambda valve is still in place however not being powered.

If I'm successful in getting the new system working with stock boost then I'll probably bump the boost up to 1.0 bar then dial it in again. THEN add in the FrankenCIS WUR and continue with having FrankenCIS take over control of the full CIS system.
