Default LM-1 vs. HPTs Histogram reading

I think I've posted a thread like this about 2-3 times before. I seem to run into a new problem each time.

I've having a problem with the LM-1 reading not displaying the same values as the histogram... My guess is the Histogram is off.

For example... Given a certain RPM & TPS my LM-1 will read perhaps 14.0 while the histogram shows 16.0... It seems to be about 2 points off but, this is just an example.

This has to be some setting to either the histogram or LM-1... Just a matter of dialing it in I'd guess. I'm not sure exactly, ''what'' is off however.

Any ideas?

Have you set the voltage on your LM-1 to 0=10 and 5=20 then you could use the PLX calc pid and it should be dead on

the formula would be afr=v*2+10
