So I have the SCT X3 from Steeda, which is running 1.2.136 firmware. There was a "critical" update that came out in July which is 1.2.142, and you have to auto update to this software, which mine will not do from my computer. Is anyone else having this problem?

Also, this update supposedly fixes an issue that returns the car to stock on it's own, and my car would run great right after a tune, then would run like crap and gas mileage go way down within a week of tuning, anyone else have the same deal?

My device is installed correctly to my computer, and I have the updated SCT software, but it's telling me that 1.2.136 is up to date, very frustrating as this may fix my issue.

Boss manifold, Steeda CAI, Roush axle back, FRPP 4.10's, SCT X3 92O tune, Steeda short shifter/black bushing, Motegi MR122 wheels, Falken FK452 tires (siped), 3DCARBON spoiler, 35% tint, custom dash/gas cap badges, 8" Alpine INE-Z928HD nav, Viper alarm

Hello Mac,

Have you contacted SCT in regards to this issue? Send me an email at tim @ and let me forward it to our tuning team and see if they have seen this issue before.

Best Regards,
