I haven't looked at Tunerpro in a while...I know on datamaster there is a box that flashes I think red/green with text for open/closed. Have you checked in all the menus?

I don't think you will be able to adjust blms in open loop either.
Are you running a heated o2 sensor? I had a problem with mine dropping in/out closed loop. Matthew |

Datamaster has a box at top RH that says Open Loop in yellow in OL ;shows Clsd Loop in green when in CL When O2 is working correctly ,O2 voltage should rapidly change from say 300 -700 and back again Quote:
Stock the CL timer is set at 3 minutes for a cold start. |

How do you know if you're running rich or lean in open loop? Common senses, spark plugs, exhaust gases or wideband O2. New TP Version 5 has the "closed loop" checkbox on the bottom of "Show Data List Views". The old Version 4.x, which I still prefer, has it under "F" values. |

That doesn't tell you if it is running rich or lean in open loop. But I guess just get the BLM's right in closed loop, then it should hopefully be running correct in open loop. |

I don't have a wideband 02, I keep everything stock. Don't have anything to check exhaust gases with. Don't see how you can look at spark plugs to check if its running lean or rich in open loop. |

In case you still need to know... Below the large variable window (where ALDL Dash items are normally being monitered), you'll see 5 tabs. ALDL Values ALDL Dash ALDL Flags ALDL Monitors Item Comments About the 3rd item down on the ALDL Flags tab is the Open Loop status. It'll say OPEN or CLOSED. |
