Lund Racing Tune issue

[Platinum_5.0]

So an SCT employee is telling you that an X4 can't do a crank re-learn? That's pretty bad considering the option is right there under the special functions and I had to actually pull over on the side of the road after my clutch install because I forgot to do it and car ran like shit. I pulled over, grabbed my X4, did a crank re-learn and everything was fixed. Car is a 2017 5.0.

SCT BDX which is between the GTX and X4 and have had to use crank relearn before.

Did hear back from Lund. They said a Crank Relearn is pretty normal for a new tune. Which is fine. Just appreciate the heads up and the recommended solution for said P0315.

Fwiw I always get a p0135 when going from aftermarket (Lund) time back
To stock, but have never gotten one going from stock to Lund tune.

The current firmware of a Lund ngauge will perform a crank relearn, but the older versions don’t. AFAIK every Sct x4 device will also do it.
