I have a LM-2 and it has been priceless....

I bought the LM unit a few months after I got my junk back on the road after it sat for 15 years. Played with the LM, tuning, etc and the car ran quicker on its first pass off of the trailer than I was hoping it would go when sorted out. No doubt the LM unit was the reason...sure wasnt me...

I played around with E85 for awhile and it would have been dang hard to have tuned the carb without the LM unit...
