azZdriver Posted January 6, 2011 Share Posted January 6, 2011 I am using MS2 and the relay board. Even with the cylinder head temp sensor removed I am getting the same false readings. It reads 0 degrees F then jumps up to the sixties randomly. I have also posted over on MSEFI.com but have not found the solution yet.

azZdriver Posted January 6, 2011 Author Share Posted January 6, 2011 I am running TunerStudio and set Thermistor values as follows: 2490 bias resistor value 10c/14F=9K ohms 20c/68F=2.5K ohms 50c/122F=.84K ohms Quote Link to comment Share on other sites More sharing options...
azZdriver Posted January 8, 2011 Author Share Posted January 8, 2011 OK I tried a few things: new wires to sensor, replaced vacuum hose to MAP sensor, reset MS2, put the settings in again. The erratic behavior is gone, however my temp reading is over 160 on a cold engine. Also there is a typo above, forgot to type the negative sign, my settings are: 2490 -10c/14F=9K ohms 20c/68F=2.5K ohms 50c/122F=.84K ohms Quote Link to comment Share on other sites More sharing options...
azZdriver Posted January 9, 2011 Author Share Posted January 9, 2011 Ok screw it, I bought a GM sensor, it's reading correctly. Quote Link to comment Share on other sites More sharing options...
