Looking for some info. Also posted in the RV7 forum. Have Vans CHT that is pegged when powered on. Does anyone know the resistance the sender should read in a 90 degree environment or what the resistance across the sender inputs on the gauge should be. Sender is the IE P-100. If this is a pt100 type sender, I should see 112.45 ohm at 32c (90f), but cant confirm this.
