DIYPNP/MTX-L Signal voltage
I know this subject has been beat to death, but I'm coming up with a voltage difference between my MTX-L output and where it meets the Db15 connector. From the MTX-L it measures a steady .5 VDC Lower than where it meets the MS. So where is the extra voltage coming from? I'v tried about a million different ground locations, so I have ruled that out. Is there some reason the MS would be sending voltage to the connection?
This thing is driving me batshit crazy.:crx: |

Pics always help. I do realize that soldering is the proper way, and all other connections are soldered. This one is using a butt connector because I don't want to solder/heatshrink the connection until I'm sure I won't have to take it apart again.

use the custom calibration for the AFR input, make it match and win.
I have to use .22v for my 7.35:1 value. your DMM shows a .06v difference. |
Yeah, it was bouncing back and forth between .5 and .6 difference when I took the picture. Ok, I'm trying the custom linear wideband setting, and it seems to be working. Getting the voltage at 22.3 is easy, how do I calculate the what voltage should be at 7.35?

thats just what i changed to get my two gauges to match.

Cool. I'll set the point at 22.3 and play around with the 7.35 to match. Really appreciate the help.
