I am using dual Innovate MTX-L widebands now instead of the single AEM. It seems to be working pretty well now. The weird thing is, i just pulled up one of my maps and I don't see the PID settings anymore under O2 control? Maybe Haltech locked them out? I am on firmware 1.06.2 and ECU manager 1.10. I didn't even notice they were gone!

All the same, the whole PID tuning thing sucked anyway, Haltech never adequately described how to tune it, as usual. It would have been a big help to at least know what increments to use when changing the settings, since you have to shut the engine off every time you changed it which totally sucked!

 

Your firmware must match the ecu manager to be able to adjust all the settings. When you upgrade the firmware it will convert those PID settings in 1.06 to the proper ones in 1.10 so you will be able to adjust them again.
