you need to get a multimeter with a duty cycle option and connect the negative to ground, and positive to pin 3 on the round pin commector on drivers fender. try doing a seark using lambda as your key word, you will find some good info.

Lambda Duty Cycle Test Results:

Cold Start 90 deg
Key On, Engine Off 49.9% 49.9%
Idle 25-30% 20-24%
2,000 rpm 30-35% 32-35%
2,500 rpm 35-40% 35-40%
