Hi there,
I'm about to order parts for my engine rebuild. The plan is to upgrade a 2.0 GA D-Jet engine as following: 2056cc Stroke 71mm (stock) CR 9:1 Raby 9590 cam SSI Heatexchangers Original Muffler The only thing stoping me right now is that I need verify CO2 emissions every 2 years here in Germany. My questions are now: 1. Does this set up idle well and stable at 900-950RPM 2. Does it reach the 3% CO2 spec. in idle I know that a none stock cam should not idle so low, this will be just for the time of the measurement. Without reaching this spec values I not able to register the car here in Germany :-( Thanks and best Regards, Frank |

Idle speed of 1,000 is where I optimized the 9550. Lots of people run these in California and other states that require sniff tests without issue.
The trick is adjusting initial advance to 14* then limiting the full advance to 28-30*. If you must get a sniff test, run the lowest octane that you can find and get the engine hot just before the test. |

I just happened to stumble across these settings when tuning MS. This seemed to give the best MAP signal and throttle response. |
