    Weird sudden's immediate.

    Working on my tune for my Beretta (7730 $A1) and ran into a new problem. I've been using this same car, ECM, sensors, etc and basic tune for many years. Changed heads & cam and injectors and the main thing that's different is the BPC vs EGR to account for the injectors.

    Several times (probably almost a dozen) in the last couple days it has suddenly stalled. And it's immediate like I turned the key off. Fires back up no problem though. And it has only been while idling, or when coming back down to idle after disengaging the clutch. I noticed in the logs it goes from normal readings to dead readings in one sample. Capture attached.

    Not sure what I got going on here. Any ideas? Attached a log and my ADX too. Thanks
