sct X4 issues

Str8Ugly · Mar 24, 2015

ive been deleted since last august with the sct x4 tuner i got from no limit fab, i just tried to go from my street tune back to my load first tune which im assuming is ok and its the equivalent to stock power just deleted. everything went as planned followed the directions as per the programmer. i try and start it and it starts and runs for about 15 seconds then dies on me, i have p200c and p200e codes both having to deal with sensors. but i can reload my street tune on the truck and it cranks up just fine. what gives? what do i need to do so that i can load my different tunes on my truck?

Load first file is not your stock file you need to load that before you load a deleted tune. Tow tune is the lowest power offering I believe so you would need to load the load first file then then tow file

so there is not a deleted stock program?

I don't even know what the "load first" file is. I didn't have one.

Never heard of a load first.

Just ordered my deletes and tunes today, can't wait haha

I have a '15...with an X4. All I had to do was load the tune I wanted....DPF on and off didn't matter.

Just got an email with my tunes and see the load first one so I gotcha

Must just be some tuners using that file? Weird....

Mikeyfitz · Mar 25, 2015

Dunno, but I might as well do it lol.

just guessing here, but i'm thinking it's for the custom tunes. i didnt bother trying to load the canned tunes on the X4, went straight to the custom and I had the load first file as well.

I have to disagree, Mike.
I got my files via email from our friend. The only thing on my X4 is a street file and a race file. I have never once loaded any other file on my truck. DPF on it was just the street file and DPF off I returned to stock then loaded the new street file. I don't know how or why...I just know what I have.

OK...got some clarification. Load First is only for delete files. Since I already had a DPF on file loaded and I guess I just wrote over that and didn't return to stock first (thought I did but I guess not) the first DPF on file acted as a Load First file. That said....I've still never seen a Load First or loaded one but apparently there's a work around. If I ever return to stock then I'd need to use that file first.

It just depends on who's tuning you're running, load first is what you do before loading a custom tune. You can go between any custom tune with out having to do the load first tune again, but if you program back to stock you will have to do the load first tune again before going to a custom tune.

Mikeyfitz · Mar 26, 2015

That's what I was curious about was having to do it each time I wanted to switch between tunes. Cool business, waiting is the hard part now lol

SEABEE08FX4 · Mar 26, 2015

Yeah its only done when going from stock to custom, custom to custom doesn't require it.
