Curious...AWD converted to RWD.

[JDM_Man]

Confirmed today in the rain, traction control does NOT work. Now with this being said I believe traction control is also used for stability control so I think its safe to say that won't work either.

My first few cars didn't have any TCS or stability control and I never crashed any of them.

But then again none of them were rear wheel drive, and the most powerful one had about 164hp.

The point is those systems don't work and give no error so someone could assume they are working and kick the car out into a ditch or fair worse in a severe crash from no stability control

So in theory (if I'm understand everything I read) this fuse could go out and you'd have no idea your AWD wasn't functioning until you started losing traction. And if as @JDM_Man says it also disables the stability and traction control without any kind of warning that's a potentially dangerous design. Surely I misunderstood and it doesn't work that way.

@JDM_Man you're not getting any kind of light flashing on the dash when you lose traction indicating the system is still working? Like it's just off completely?

I could swear I see a difference with TC on and TC off. Its by no mean as good as awd, but I can smoke the tire easy with it off. I will have to double check again tomorrow. And stability control definitely works, the car is a handful when its off.

 

[Frenchy_418]

Have you actually tried to disable them and see how worst it gets? Or you just happenned to lose traction with a 365hp rwd car in the rain?

I feel like the stability tuning varies car to car, probably was refreshed at some point. I could never break the car loose (AWD) unless it was really wet or snow on the ground. My car was NOT a handful, even with a Map 2 JB4 tune. Comparatively, the stability/TCS is much more loose in my BMW in Sport+ than my Stinger was with all assists off and in sport; the Stinger would cut throttle if I tried to break it loose - with everything turned off. I wonder if some of your Stingers are a little more lax on the assists.

I am going to revisit this, studying document after document this is something that KMA (Kia Motors America) refuses to publish other than subtle hints about making this car RWD.

I've looked at the AWD system and how the canbus communicates with the AWD system. This fuse in only live, under 60KPH. The entire front end of this car, is turned off and we do indeed have 200lbs or hurling axles, and a front diff just spinning and not doing anything, this is the main reason why we have no CEL. or error codes on the dash. Zero power to the front end over 60MPH. By removing this fuse, in theory the car decouples the clutch and there is ZERO chance of it engaging. I would like to put this car on rollers and a multmeter showing when power is applied to this circuit and study it a bit more. Seems like a simply fuse tap/relay switch to convert AWD to RWD.

Why? I am going to put a LSD (Limited Slip Differential) in mine, and one day have the ability to go RWD at the track.

Did you ever end up doing any more testing with this? I would be very interested in doing the same with the LSD but am finding very little information on how the AWD system works with this.

I haven't. I am still looking into it, but honestly with the 2021 coming out soon I am losing a little interest. Depending on the changes...well you know the rest lol

So I actually just got off the phone with a Kia dealer who looked up parts for me. Apparently my 2020 AWD GT2 is mechanically the same as the 2020 GTS, but has different ECU/TCU programming. The parts guy said that essentially the only difference is an electric shut off for that AWD fuse. I'm not sure the difference in torque vectoring vs whatever the GTS uses to know if literally pulling the AWD fuse is the same as drift mode in the GTS

I'd be curious if you can swap the GTS TCU into the GT2 AWD.

I'm 90% sure it's software. These early model AWD units really need a LSD. I'm not sure if the mechanical change is also a software change.

I'd love to try a LSD in mine, but not 100% certain the electronics would let the car go "sideways" with 100% freedom

My little brother and i had dsm's in highschool
I had a fwd tsi talon 2g he had an awd eclipse gsx 1g

We had fun but one day he was unsupervised and removed his 2 front axles to 'make the car rear wheel drive'
It ruined the center diff and trans from obvious missing parts.
Yes very different circumstances but i do not want to see stingers with melted center diffs or anything like that so there i said it.

Technology is totally different. I was skeptical coming from the Subaru community.
From what I've seen the dif can go from 50/50 to 0/100 F/R torque split without issue.

Similar systems are used in the awd sport utilities that run the drive train in 100% fwd when awd is not needed. It's all electrically controlled.

The Stinger just has the system reversed so it is a rear bias vs front.

 

[street heat]

this gives you 100% to the rear wheels ?

 

[SnowyGT2]

Using the above and switching from Sport AWD to RWD makes a difference for sure. Can't say if it's 100% power but the rear tires spin a heck of a lot more.

 

[Tonkabob]

Yes it's 100%

 

[WearySky]

Any Canadians with the GT Limited (which comes with LSD starting in 2020) try this out?

 

[StingaGT]

I really wouldn't do this knowing that what people will try after taking the fuse out.
AWD components aren't designed to handle 100% power at rear.

But this is exactly what the GTS does. With the same components. The rear axle / diff are the same as the RWD versions save for those with LSD.
I was sceptical at first as well. This is not like other full time AWD solutions. Center diff torque transfer is variable from 0/100 to 50/50 based on the voltage/current coming in. Pull the fuse = 0/100
