Or have you disabled them? Try setting 1208 to Enabled and 1210 to Type 2. You must have the V2 connected to the computer that has the new file on it before actually opening the new file. Use the right most full flash red arrow. A good practice is after the full flash, download the ECM and compare what you think you modified to what is actually in the ECM. Be sure to try 3 non-starts before starting.
