After some research and development (no diagrams on the internet), I have been able to make a CIS-E fuel enrichment module from scratch. Autotech and Techtonics sell these for over $100. I built mine for about $15 and some time. I installed it tonight and bench tested it in the car, checks good. I will try the butt dyno tomorrow. I used a 10K pot but now I think I will go with a 1K resistor because the pot will probably adjust itself under vibration. I know that the Autotech module is adjustable for different engines, if anyone has one I would appreciate some resistance readings for reference.
