Just replaced OEM clutch and flywheel on my 2017 GT with a Clutch Masters 350FX stage 2 clutch and lightened (13lbs) steel flywheel. Immediately started throwing P300,04,07 misfire codes (cylinders 4 and 7). Mechanic who did the work for me is very good and had no idea why the misfires. I changed the spark plugs (needed to anyway) and swapped ignition coils 4 and 7 to see what would happen. No change, same misfires on 4 and 7. Jumped on the forum and came across this post and mentioned it to him. He was skeptical since he claims he's never had to do any adjustments after a clutch install, that said he works primarily on Porsches. Took quite a bit of sleuthing around his Atul scan tool but finally found the crank relearn function. That fixed it! This saved a lot of time and energy. TY for sharing!
 
What if I need to a crank relearn but can’t get the sct tuner sent to me because it’s not legal in California?
Dealer can do this, but I am sure they will charge you to do so. Takes less than a minute to do. If you can find someone local you could use their tuner even though it is not paired to your car. I used a friends of mine even though it was paired to his car.

Thank you so much you earned me some sleep this morning, so it can be any tuner then? Right?

And I can take off the check engine light as well right?
