Matt Cramer Posted January 9, 2012 Share Posted January 9, 2012 TunerStudio going offline is either a problem with the power to the MS being interrupted, or noise interfering with the serial coms. Neither is going to show up in the diagnostic logs. Are you using a serial port or USB adapter? Quote Link to comment Share on other sites More sharing options...
Dadaluma Posted January 9, 2012 Author Share Posted January 9, 2012 yes I am I have tried 2 different serial adapters Quote Link to comment Share on other sites More sharing options...
kaito Posted January 10, 2012 Share Posted January 10, 2012 (edited) I personally have used the usb to serial adapter that diy sells with no problems. Like Matt said, you have some noise or power problems. Make sure you have power while cranking. You should verify that all your grounds are good, and be sure the sensors are grounded to pins 14-19 on the controller. I personally grounded all my sensors to pin 19.The megamanual says something about the hall circuit sometimes having noise problems. You could check it out and maybe try some of the recommendations? Heres the link about the hall stuff, http://www.megamanual.com/index.html step 50, Also http://www.megamanual.com/ms2/inputHEI.htm Just a few easy things to check before you get too in depth with troubleshooting. Good luck. Edited January 10, 2012 by kaito Quote Link to comment Share on other sites More sharing options...
