my suggestion
1. perform DATA INIT
2. turn car off
3. turn car to ON, but don't start it
4. set map sensor settings via datalogit (or hand controller)
5. set boost kit off
6. check SENSOR SW CHECK and make sure no sensors are black highlighted
7. start car and perform self idle adjust process (this is documented in the FAQ)
then it should be stable and it should idle
note the self idle adjust is meant to run for 30 minutes......
