1. I can't test as I haven't bought yet. (I won't buy a vehicle I can't disable stability control on.) I'm hear doing research on the CX-3. If this is figured out my plan is to buy one, lower it, get a header fabbed, and possibly do cams from Orange Virus.
2. Same as 1, I can't answer this one as of yet.
3. I believe you missed the point of my Subaru posts. It was not to try to duplicate they things they've done, it was that they have threads and people actually trying various ways to disable. That aside trying some of the same things they've tried would be a good starting point.
4. This really has no point here, as we aren't comparing AWD systems, we're talking disabling stability control. My current daily driver is FWD until wheelspin is detected (I can lock in 4wd) and it drifts quite well, even when I don't have it locked. Disabling stability control also allows it to get through way more things off road than when it's on. There are hills I can't get up with it on, that I can literally stop on, then continue with stability control off.
5. Yes being able to disable DSC could make it nice in certain situations. I too have previously owned a Subaru (WRX). It didn't even have TC or stability control, and it didn't need it, even with much more power. For me being able to turn off the nannies is a requirement as I'm a 30+ year old kid, and I'm going to play in the snow with whatever my daily is.
7. It's a 3000GT VR4.
1. This question was directed at those already commenting that the DSC cannot be turned off on USDM (maybe all North American?) models. While it wouldn't necessarily surprise me if true, given all the other weird regional differences on these, do we really know for certain that this is true or is it just a feeling we have? The evidence presented so far has been one person confirming it by saying his car "freaks out" when trying to do donuts. Do we know that "freaking out" means it's the DSC/TSC system doing stuff or that it's just the nature of the particular AWD setup this car employs? It's likely to be some combination of the two, but I'd be willing to lay a heavier share of the blame on the relatively weak engine and AWD system rather than the DSC. I haven't looked into it, but it's possible that DSC systems, if equipped, are not allowed to be turned off by law here in the US in the name of safety.
2. Same as #1
3. My point there is that you may be barking up the wrong tree looking at what the Subaru guys are doing. Two different systems with different sensor arrays and different control logic. At best, it might give some ideas of the type of signals you can look at, but the array of signals employed here may be very different. You'd probably be better off doing some research on Mazda's TCS/DSC system to find out precisely what signals they are using to control their system. What Subaru or anyone else is doing may be entirely irrelevant.
4. Ah, but I think you're missing the point with my discussion on the differences in our drivetrain... I bring it up because I suspect the lacking engine horsepower and the way our AWD system works in the CX-3 are possibly more to blame for its weak ability to do donuts and "super dorif-tooooo" than the DSC system. i.e.: I don't think the DSC system is necessarily the problem you guys are trying to "correct."
So far, no one has been able to confirm for us if the TCS/DSC indicator is flashing when trying to do these donuts to indicate if it is, in fact, actively trying to straighten out the car even with the TCS button off. All we've heard so far is "the car freaks out." What does that mean, exactly? How do we know for sure that the DSC is not disabled? There's no indicator light that I've found for any CX-3 trim sold in any region to confirm DSC is off, yet others outside the US say they've disabled it. How do they know it's off there but not here? Proof seems lacking. Other cars like Subarus and the Speed 6 have very different setups and may explain, at least in part, why they don't see the same behaviors while drifting with those even on other cars with TCS/DSC systems. My Forester had both systems and I had no trouble drifting that sled around and I didn't have to disable anything to make it do so. The full-time AWD was much more predictable and smooth than our part-time setup when trying to do stuff like this.
What you're describing with your daily driver is a problem with the traction control system in your car, not with dynamic stability control. Stopping on a hill and taking off again in poor conditions is a traction problem, not a vehicle stability problem. DSC only engages when it detects yaw (sideways movement) while moving. Stopping and resuming on a hill is not a dynamic stability problem unless you're sliding down the hill sideways or something. Mazda's owners manual even talks about the exact situation you're talking about and recommends pushing the button to turn off the TCS if you have this problem.

5. Could be. But I think that's speculation at this point. As I said, I had no issues drifting my 2010 Forester that had both TCS and DSC systems. I could happily make that car drift smoothly, do the Scandinavian Flick, etc. whenever I wanted in the snow. Something else to consider is that not all DSC system are created and tuned equally. Subaru's system may be tuned to react less aggressively than the one used on the CX-3 or vice versa. I haven't seen any testimonials yet that can definitively point to the DSC system as the limitation of the CX-3's ability, or lack thereof, to drift. The "freaking out" claim that's been made could just as easily be attributed to the dry clutch system suddenly engaging the rear wheels mid drift. Whether or not that's the DSC system that is causing the clutch to engage is certainly possible, but I think that's just speculation at this point.
If hooning in the snow is your game, and I have no grudges against that, I think the CX-3 is probably not your best option. The lack of horsepower doesn't help it do what you want, and probably the main thing is that the car is just setup to do everything it can to keep its occupants safe, which includes correcting skids, even if they are intentional. I haven't had any trouble getting the rear end to swing out when I want on my CX-3, but I can't say I've personally tried doing donuts (yet >
6. This goes to the point TiGrayMSM was making about the differences in behavior between his old Speed 6 and the CX-3, despite the two cars having a similar hardware scheme controlling the rear wheels. The CX-3 uses a wider array of sensors to control it and has completely different control logic. The CX-3 is setup for safety, efficiency, then performance while the Speed 6 is seemingly setup for performance first, safety second. The Speed 6 almost never disengages the rear wheels except for a very limited set of circumstances. This contributes to the predictability of the handling of the Speed 6 and it's ability to hold a smooth drift in snow vs. whatever it is the CX-3 is doing. Of course, the Speed 6 is also making over 100 more horsepower which helps break all 4 tires loose while the CX-3 will feel more grippy and less likely to hold a drift when all 4 wheels are driving.
7. Yep. The engine even has Mitsubishi badges on it. His car has a rather rare option on it as it came with the straight-ish 3000 GT rear wing on it instead of the weird boomerang wing than the Stealth normally got. Previous owner said it came that way, but I'm guessing that was probably a dealer-installed option. I don't recall ever seeing another setup that way, but I like it much better than the Dodge wing. I should see if he's got that car put back together yet. The stock turbos bit the dust a while back and he had a head gasket leak he was fixing up along with a few other odds and ends while he had it apart. He's got a new set of aftermarket turbos and intercooler(s?) that should put the power up around 400 HP or so he says. He didn't want to go too big on the horsepower because the transmissions in those cars are rather notorious for being made of a substance that looks like steel but seems to actually be made of glass.
