AFR monitoring on carburated small block Chevy
Discussion
Old school small block running Holley carb. Running side pipes with lambda bungs just after the collectors.
What do folks recommend for monitoring AFR to help fine tune carb jetting? I'm looking at the Innovate MT-L and LM-2. The MT-L is more for real-time monitoring, while the LM-2 does data logging, etc. The LM-2 requires an RPM signal, too.
Does anyone have experience of AFR monitoring on a carb motor running conventional ignition? Any alternatives to the Innovate stuff? Any advice welcome.

What type of manifold ? single plane or other ?What do folks recommend for monitoring AFR to help fine tune carb jetting? I'm looking at the Innovate MT-L and LM-2. The MT-L is more for real-time monitoring, while the LM-2 does data logging, etc. The LM-2 requires an RPM signal, too.

LM2 will be handy as you can record both banks ( with 2 sensors of course ) and it can log other channels on-board. Logging AFR's on their own is meaningless without some other reference....rpm at a minimum. If you also want to throw in TPS there too ( or maybe manifold presure which can be easier on a carb ) than that's even better.
At least you can then get a picture of when/where any fueling changes need made.
As much as I have a dislike for the reliability of Innovate widebands....here it would be a good choice simply because it can do everything you need with one box.
Daytona Sensors makes stuff too, but you'd have to buy it from the US, and it will be more expensive, probably quite a bit more.
I'm kinda torn on whether to go for just a gauge and eye ball it whilst driving vs a data logger like the LM-2.
Saw the Daytona stuff... yes, a bit pricey. The Innovate products do seem quite good value.
