SCT x4 Use and troubleshooting

[tmcphail]

The D loss is real high through the AWD system ford uses. That % isn't inaccurate.

Ok, so working backwards with stock numbers, Torque, Dash Command, and 1/4 mile times, my crank power calculations are....

476 TQ
443 HP

Reasonable?

Corrected for DERP!

SHOdded, are you getting tired of my noob questions?

LOL!

You know it!!!

Torrie, I had my Reische 170 installed yesterday, do I need a tweak?

[tmcphail]

Yes

[MDesign Performance]

Do these kits have a low level warning built in?

Just for future reference, you can use a low level float switch and wire it up to an LED to retain this feature using any container. They're pretty inexpensive, below is an example. Maybe Torrie can start stocking these or add them to the meth kit.

I always use the factory washer reservoir that way you can retain the OEM low level system. That is unless you want to mount a huge reservoir in the trunk. 

[FoMoCoSHO]

Yes

Ok, do you need a datalog?

[tmcphail]

No, just email me and I will handle it

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?

[tmcphail]

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

[f8tlSHO]

Correct. I don't like to see it below 1000PSI

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