Re: Not for Nuthin' But Close!
Ok cool.......what can you adjust in open loop? Can you monitor a/f ratio?

Re: Not for Nuthin' But Close!
Yes and No. There is an afr shown in the data log, but it shows that it is the commanded ratio by the ecu. However, when I started to mess with fuel, it did start to show leaner values. The 02 voltage is also shown, and is somewhere around .8 - .9 going down the track.

Re: Not for Nuthin' But Close!
Just FYI that Mike Cashman has posted pics of the car in the FB Stock and Super Stock Racing group, assume the pic has Doug and Billy in it. Very cool little ride.

Doug, Am I confused? Isn't output voltage like lambda? .8 = 11.76:1 .9 = 13.23:1 Stan |

Target on NA is like .850 wot in PE or power enrichment mode. A lot of tuners using the HP Tuners logging set up an Analog input from another wide band for a better Air Fuel ratio log. Older factory ECU's are narrow band 02 sensors. . More modern are wide bands
