I have a ms3x on my 03. At operating temp it idles fine and then the cuts out randomly and the "no fuel cut" light in tuner studio goes red for a split second.. then proceeds to idle fine again for a couple seconds and then ... Bam, it does it again.
Any help would be appreciated. I attached a data log--- (at the end is me pulling onto the driveway and shutting the car off)
Likely, it is going to fuel cut because you are telling it to. Look here in Tuner Studio and see what settings are being met and causing fuel cut:
Else, for starters, turn fuel cut off and see if problem goes away. That will point in the right direction.
Posting your tune, along with the log, would be most helpful, or, as mentioned above, look there and figure it out for yourself.
In addition, with engine off, MAP is reading 91kPa. It should be close to 100. Look at how to correctly set the MAP sensor.
Lastly, post an introduction in the Meet and Greet and become a part of the forum. Tell us about your car, your plans, etc, and possibly include some pictures.

Thanks a lot! That did it. Just need to figure out my high idle. And I have posted about myself and plans for car it has just been a couple years. But I will since I got a couple new Miatas. Thanks again!
