20B Spark Trig setting for Microtech LTX-12
 

After having some problems trying to time my engine I was advise to check the ECU setup 31 screen to see what the Input and Spark Trig settings were. The manual says both should be +pos. However Spark Trig is set as -Neg on mine and the other option show SER4. No option for positive. Can any other 20B owner with Microtech confirm if it should be on SER4 or if it is fine where it is?

Will post in ECU section as well of course but figured it might be more 20B specific!

Thank you
