Wired system and programmed bypass without issue. When using the 3x remote start function, vehicle powers on and give no-tach flash code. How do I configure the tach on the Spark?

There is a random issue with GM vehicles that sound like the problem you are having. A technical agent must assist you to troubleshoot. Give a call to technical support.
