Lean Burn monitoring in VX

thanks

I also built the autospeed kit and it also shows 1 light richer for injectors off than for leanburn. Not sure why. Have not checked the actual voltage yet.

I made two of the one light monitors. I have one set to lean burn and one for injectors off. They work great, I need to run a couple tanks and see if they help me. I would like to leave the DVM hooked up but I think i'd watch it to much.

Changed the thread title to reflect the direction the discussion is having.

I'm shooting for the second week in June to get my displays together and installed in my VX

My first tank after installing the monitor was 57mpg!
I really want to break 60mph. I think we should be able to have summer and winter averages seperate. I will take me all summer to get my average up.
Now i need to fix those rust holes and paint.
