migration from D180 > CHT & Oilpressure dont work

[laminar]

I changed my D180 to a SV700 and are having trouble with sensors.

1) Problem with CHT: Indicated Temperature is about 15 deg celsius to low

The D37 cable from my old D180 had CHT 1 and CHT 2 at pins 4 & 22 - I mapped these sensors on my SV700 to the same pins. I tried all sensor types, best result with "Rotax sensords" (which are installed)
I measured resistance of cht sensors and oil temperature sensor (which shows correct value); they all had the same resistance (1.6 kOhm @ 13 degrees celsius)

what else could I do ?

2) Problem with oil Pressure: oil p widget is "crossed out" on the screen, the sensor debug data shows Value "na"

I mapped oil pressure to pin 6 (as it was on D180) and choose the installed Honeywell sensor. d180 and Sv700 both have pin 15 with DC+12, so to my opinion it should work

any ideas ?

3) Voltmeter
SV700 wants voltmeter @ pin 1 or 2 - D180 did not use these - is there any other idea fpr the voltmeter than to connect a new cable to pin 1 ?

thx for your help

1) The D700 doesn't use a 1.21K resistor on the CHT's. You need to remove these.

2) The Honeywell sensor was broken in 1.0 firmware. You need to be running 1.5 or 2.0, with the config file and sensor file updates.

3) You must hook your voltage source to pin 1 or 2 if you want to monitor it on the SkyView.

thank you !
that will solve the cht problem

regarding oil p

I think I updated everything already
which "config file" and "sensor settings file" is the latest ?

thx

The latest ones are always the ones published on the SkyView downloads page.
