Just looking for clarification Thanks |
Mine is now set at 55% with BLACK to green wire on test port & RED to ground. If I reverse this I have a reading of 38% Duty. Can any one confirm what is the proper hook up procedure. Cheers

With black clip to green wire and red to ground, what duty cycle are we looking for at 1000 rpm idle? Apologies |

This does correspond to approx 0.8 % CO at 50% duty cycle with sensor disconnected, means open loop for doing the test with a CO measuring tool. |

http://forums.pelicanparts.com/uploa...1681079109.jpg So duty cycle 55 for factory idle setting but 40-45 to achieve proper mixture for acceleration and WOT? Sorry Damon88 don’t mean to hijack. Thanks |
55% at idle is for factory standard (max 0.8% CO).
40-45% at idle ends up in a higher AFR at WOT.:-) Sorry I was thinking of my own developed ECU, where you always set idle to 55% duty cycle and you can set the AFR for WOT individually via software. |
