How to log AFR or lambda values on the durametric logger ?
There seems to be quite a lot to choose from
Thanks guys

 

When I was messin' around with my car,using Durametric,we use to watch the O2 sensor voltage readings to see IF we were running lean or rich.It was some time ago so my memory of the details IS a little off.
We logged Engine load,ignition angle,Mass air flow,RPM,Exhaust temp,and both O2 sensors upstream and downstream.....

If I do remember correctly you want your O2 sensor readings to be around .089 at WOT(wide open throttle) BUT do some research on O2 readings to find out what is optimal/safe to run......

Hope this helps just a little!

I don't know if you have already read this thread:

I find it to be quite useful.

 

THAT is the best link to info!

 

Yes, great article.

 

Hey Stacy,
Thanks for the information.
Data logged this morning. SOme interesting results.
I can log O2 sensor LSU voltage numbers but cannot log nominal or real lambda values. I may have faulty O2 sensors ?
I am not sure how you can convert the voltages into AFR's ? with the real value that is easy ---- simply multuiple by 14.7

 

From what I read on that link ......yes multiply 14.7
