You're welcome. I'll try and find the readings I got when I had my car checked ages ago.

When I passed the smog emission test it wasn’t so good, so I’m trying to adjust it by myself.
First test with the lambda probe disconnect (mine is from 1999)

On the other hand, when the micro-switch is on, the value exceed 60% (don’t know why yet)

After a few adjustment, seems fine to me

For now, impossible to unscrew the old lambda probe. Once it will be replaced by the new one, I’ll be able to see with an air/ratio meter where I am exactly.

With the oxygen sensor disconnected you would need to use an exhaust gas analyser to set the mixture. You wouldn't get any dwell feedback with the sensor disconnected (it's running open loop) and it will default to around the 42-45 mark. When the full throttle micro-switch is depressed the dwell reading will increase to around the 52-55 mark.

Sounds like it's running sweet enough :thumbsup:

Thanks for the advice, I'll try to see what can I can next once my old lambda will be replaced.
When the full throttle micro-switch is depressed my dwell doesn't read anything. (>90 & probe disconnected)

How is that Sport-Comp AFR meter reading the mixture?

Is it taking an electrical measurement from your old lambda probe that you can't get out?
