LC-1 gauge and MSPNP doesn't agree on AF value
 

There's about 0.5 in AF value difference between the reading on the MSPNP (89-93) and the LC-1 Gauge.
Anyone have a clue how to make them talk the same language, and to which one is correct?

The MS reads the signal to be leaner then the gauge, so either way, I'm running it richer. It's still not optimal though, so I'd like to figure it out.

Is it just a small adjustment to the MS, or do I have to get hard and handy?

It's been like this since I installed it, and both the LC and the MS was new.

This is a pretty common issue. You also posted it in the wrong forum.
Search for it and you'll find countless threads on it.

Its not just MS, its all the other ecus also. I'm running adaptronic and i have the same issue. The issue is with the LC1

There needs to be a stickied thread with the solution to this problem, because virtually every LC-1 installation can exhibit this issue.

Just a very small ground offset is all it's likely to be. You can tweak the LC1's analog output calibration in LMProgrammer a bit so they line up better.

i have my MS1 and my lc-1 sharing the same power and ground points and mine is .7-1.3 off at times... i have been blaming the analog gauge for being slow cause at a wot pull they seem to be even.

mine is about .3 off constantly. not too bad considering others have had it worse. Not too worried as long as megasquirt is getting the accurate reading and the gauge is just a little off

So it's the MSPNP who's getting the correct signal, and the gauge who's a bit off?
I rather be dead on my AF target, then off with .5 in either direction.
