So a tune will be in my very near future, and I've got a few questions about my options. Looking primarily at the sct x4 and obviously the ap v3.

On our cars, what is actually end user adjustable with both? As in what settings can I adjust myself.

Can the traction control be modified with the sct besides just turning it off? (If custom tune is required that's fine)

I know both can hold multiple tunes. Is a reflash required to switch between them?

Basically, I'm trying to figure out what each does better than the other besides datalogging.

For you, I'd go with the AP3. I personally run Unleashed thru SCT, but sounds like you wanna swap maps quick and what not. I don't care much for doing that so SCT suits me fine. Also the COBB TC is exclusively on the AP.

The COBB TC alone would be a hard selling point if I were buying one right now. It is seriously THAT amazing, if you do go SCT it has it's comforts like free revisions through Unleashed for example

The traction control has me leaning hard towards the ap. That and there is a good pro tinge with a dyno about 45 minutes from the house.
Is the ap adjustable for gear ratios and tire size? I've been toying with the idea of having one of my gear techs cut me a few higher gears when I do the lsd install.

Traction control can be had with right foot. The SCT allows timing adjustments, rev limiter, launch control, fan speeds and a few others with the handheld. No need for tune adjustments. They just have to be enabled by the tuner.

Yes, yes, driver skill I agree. I got spoiled more than you can imagine with the rpm slew rates and traction control tunability of the 7531 box on my old grudge race car. I know it's apples and oranges, but ignition based tc doesn't seem to upset the suspension as badly as throttle based.

I know most of those features are unlocked on the Mustang handheld, which is what's in the video, but are they enabled in the focus handheld? Sct's website is horribly vague about this.

Yes they have the same features unlocked. we are going with it on Stealth's 2.3 build so we can adjust at the track. He is currently using cobb but wants to able to adjust for slicks and track conditions.

That's what I was looking for. I've been laptop track tuning for years, and honestly love the ability to tinker at the track. I've actually started trying to find info on hp tuners for our cars for just that reason. I've used it on several f-bodies. It's not for everybody because you have access to edit every aspect of the tune, but that's very intriguing to me.

Everyone has pretty much hit the nail on the head IMO. I have the APV3 and have zero regrets. For me, the biggest thing is all the monitors you can switch through. I am also a big fan of being able to switch through slots on the map to change things such as LC, low boost/valet modes, and anything else you might want to adjust on the fly. Worth every penny, and if you do go that route, do yourself a favor and go through a tuner like Stratified or Panda etc.

Get a hold of @tmcphail and he'll set you up. He also does HP tuners. IMO the best tuner around

How would it compare to sct advantage?

Accesstuner Race should be re-released very soon and will let you do about anything... they might hold out a few features for the pro version only like the Cobb TC stuff, but who knows until it's here. If you're interested for something more along the lines of HP Tuners. It should have access to tables to alter tire size and stuff... really just depends what Cobb has decoded and/or decides to put in the software. I didn't have the ST yet when the old version was still a thing. I did use ATR for the mazdaspeed 3 back in the day. I also have experience with megasquirt and currently use EFI live for LSx stuff

I never expected to hear megasquirt brought up in this group! I've built and tuned several of those kits. Brought back some memories of burning 28 pin chips the early 2000's! I've used tweecer, dsm link, hondata, hptuners, lt1 edit, tunercat, aem, fast, accel dfi, and a little time with bigstuff 3.
Thats why I am only willing to get something that is completely end user adjustable.
