Went to the track last night and figured I would share some of my results with the AMS AWD controller. I ran a new best of 11.511 back to back with almost the exact same splits. My previous best was an 11.587 which was run a few weeks back. On the 60ft I was able to break into the 1.5s with the AWD controller vs my previous best of 1.64 so while there are obviously many factors it would seem the controller is shaving about .05 off my 60fts and close to .1 off my quarter. I think on regular tires the controller will be an even bigger advantage, I’ll test that out when I put the all seasons back on.

The auto-shift has made the car much more consistent vs playing wack a mole with the paddles. The 1-2 was always kind of hard to hit for me. Looking at my logs it shifted consistently at the same RPM every time.

Burnout works well although with an open diff sometimes only 1 wheel spins which is expected. May look at an LSD for more consistent results but I’m probably not really at a power level that needs it yet.

Install is pretty straightforward, took me less than 45 mins and most of that was trying to squeeze my hands under the dash to secure the unit.

I’m really happy with where the car is at while still using the tiny factory mid-pipe/muffler and intakes. I’m sure I could get into the 11.4s with better DA but the local track is closing after this weekend to start resurfacing unfortunately.
Thanks to AMS Performance Josh Perez Jacob Compton getting my car rolling. It surprises a ton of people while sounding stock with a kid's car seat in back.

The dragstrip run made me chuckle at your "competition" in the other lane - nice red light! (in the 1st video)

I feel bad for that guy, I out ran him twice. He almost lined up a third time and he let another car go in front I think.

Apparently AMS just released updated S/W to address the AutoShift issue and binding condition at low speed and turning:

AMS AWD Box issues with Autoshift on Red Sport

If you have this AWD Controller, see the following YT video on how to d/l the latest S/W:

That's all configured in AMS's calibration, I'd have to see if I can see the tables

This is what they have as far as description on the website.


AMS CALIBRATED AWD MODE SWITCHING
The Syvecs control module and software allows us to configure four separate AWD mode strategies that are able to be selected on-the-fly by the driver. The adjustments require no laptop or phone app, and are easily and quickly controlled via the factory Drive Mode Selection toggle switch.

  1. Sport & Sport+: 100% AWD application for improvement in straight-line acceleration
  2. Standard: Normal driving mode with optimized stock-like AWD control
  3. ECO: RWD/open differential for increased fuel efficiency and less wear on components when driving straight and without wheel slip (AWD will still engage in a high slip scenario and is not completely disabled for improved safety)
  4. Snow: Increased AWD center diff lock from a standstill, AWD lock optimized for increased stability when turning or stopping

Hit the track today after AMS adjusted my launch control since I didn't seem to be traction limited. I also raised my shift points a tad and installed AMS intakes.

Track was slammed so I only got 2 runs in with each of them being a new best so a pretty good day. Also ran sub 1.550 60fts on both passes.

I watched the latest AMS video, where AMS talks about the Syvecs AWD Controller and "burn-out mode":


So did AMS think of a real-world situation, for example, driving in fog, slowing down and you don't want to get rear-ended by some ass-hat - what do you do? You turn on the emergency flashers, but wait... there's this warning in the Syvec's Product Notes (Burn-out mode is activated by turning-on the emergency flashers!):

PRODUCT NOTES
  • Auto-Shift works for vehicles with and without paddles, and can be wired in at the end-user’s discretion. Instructions for wiring to both vehicle types are included.
  • Failure to use Burnout Mode properly can cause serious drivetrain damage. Do not engage or disengage mode while wheels are moving. The vehicle must be at a complete stop, with zero wheel spin, when activating or deactivating mode.
  • Changing calibration settings is not recommended unless done so by an experienced tuner. Calibration support and/or technical information to implement changes is not included with purchase.
Sooooo... I can't touch the emergency flashers unless my Q is stopped? Huh... am I over-thinking this?

I'm working on adding a switch on the other harness for burnout mode. I will say in many states you aren't legally supposed to be moving with flashers on regardless of conditions

Thank you for the info, great stuff. I’ll be installing the AWD controller next month. Is there an option to skip the burnout feature? I never bring my car to the track.

There is probably a way to disable in the config. I think AMS can lock some settings out to protect us from ourselves but not sure about this one.

Probably something AMS can change for you in any case.

Good call, I’ll be chatting with them soon - I’ll report back.

Hi all,

Now that you've had your controller for over 3+ months, what are your thoughts on it now?
I've also got two questions-
AMS lists the following maps:
  1. Sport & Sport+: 100% AWD application for improvement in straight-line acceleration
  2. Standard: Normal driving mode with optimized stock-like AWD control
  3. ECO: RWD/open differential for increased fuel efficiency and less wear on components when driving straight and without wheel slip (AWD will still engage in a high slip scenario and is not completely disabled for improved safety)
  4. Snow: Increased AWD center diff lock from a standstill, AWD lock optimized for increased stability when turning or stopping
With them being selected by the drive mode switch.
I assume if using personized mode, if Sport or Sport + for 'Engine / Trans' is set then this will trigger the controller?
How is the non-straight line performance in Sport / Sport+ mode? I like canyon driving and the RWD bias so not sure if full time AWD works for that. Thoughts?

Thanks.
