Proform 850 dialing it in closer

My friend who runs in Stock had an LM1 in the car for a while.
That thing would lock up all the time.

He wasn’t using it for any data logging...... primarily just a visual check in high gear.
Didn’t work 1/2 the time.

Replaced it with an Autometer gauge...... which has never locked up.

We had an LM1 for the dyno...... same thing.
If the reading got down into the low 11’s, it would lock up.
Replaced it with a Daytona Sensors unit...... never locks up.

Supposedly the LM2’s have less of an issue with it.

While the LM1 was on the dyno, I bought myself a FAST 2 channel unit because I got tired of hassling with the locked up LM1.
I haven’t used it on too many motors, but it has never locked up on me.

It has a record feature, which I would use during a pull. Then you could replay it over again afterward to see what was going on.
