I'm using the circuits from the ms3 manual. 0-5v inputs match the circuits from ext-map, ego2 etc. Then matching the AIT/CLT for GM sensors.

No diodes though. See my link for the circuits I'm using.

All my inputs are either 0-5v inputs or GM sensors.

laymen's: close enough.


edit: looks like youre doing a temp sensor.

those other resistors you found are fine, you'll just want to measure whatever resistor you use and make sure to input the actual value as a bias.

the MS uses 2.49K that are 1% error ones, so pretty spot on. That's why they are blue. Otherwise all others are +/- 5%.

it's used for the 5vref pullup.
I ordered 10 2.49k 1% for $1.

Not worried.
