SCT x4 Use and troubleshooting

[ajpturbo]

So my device needs updated apparently but it told me I need to return to stock first?

Is that true?

Do I need to put the 2 bar back in or can I do this process without starting the car?

U don't have to put the 2 bar back in but don't start it...it's not essential to return to stock but highly recommended per sct ....if ur update fails there is potential u will not be able to recover the exact stock calibration that was programmed to ur car...u can always get a stock equivalent calibration but technically that's not the same as what ur stock tune was...I've updated mine without returning to stock because I figure I'll never need it..just a risk I guess

Hi Torrie, couple questions...

On the x4 knock pid is a negative number adding timing and positive pulling?

Also for us E guys, what is the minimum rail pressure you are comfortable with?

Correct. I don't like to see it below 1500PSI

Earlier in this post you posted 1500psi, pretty sure it was for the same thing.

Ok, just wanted to make sure, cause I know you just told me 1500 the other day.
