Talking PTM Modes......Misunderstood?

So I've been having fun with my ZL1 since I got her a few months ago. I think one of the most amazing things about this car is the MRC and how it adjust the suspension.

I really think most drivers don't realize what they have at their finger tips...

I'm still learning myself.

So from what I've read and experience there appears to be 8 modes total:

1. TOUR - Everyday driving. Suspension in "soft" mode for comfortable driving.

2. SPORT - Stiffer suspension. For casual canyon driving.

3. PERF TRACTION 1 – WET /
ACTIVE HANDLING ON
. Intended for all driver skill levels.
. Wet or damp conditions
only — not intended for use in
heavy rain or standing water.
. StabiliTrak is on and engine
power is reduced based on
conditions.


4. PERF TRACTION 2 – DRY /
ACTIVE HANDLING ON
. For use by less experienced
drivers or while learning a new
track.
. Dry conditions only.
. StabiliTrak is on and engine
power is slightly reduced based
on conditions.


5. PERF TRACTION 3 –
SPORT 1 / ACTIVE
HANDLING ON
. For use by drivers who are
familiar with the track.
. Requires more driving skill than
mode 2.
. Dry conditions only.
. StabiliTrak is on and more
engine power is available than in
mode 2.


6. PERF TRACTION 4 –
SPORT 2 / ACTIVE
HANDLING OFF
. For use by drivers who are
familiar with the track.
. Requires more driving skill than
modes 2 or 3.
. Dry conditions only.
. StabiliTrak is off and available
engine power is available is the
same as mode 3.


7. PERF TRACTION 5 – RACE /
ACTIVE HANDLING OFF
. For use by drivers who are
familiar with the track.
. Requires more driving skill than
in other modes.
. Dry conditions only.
. StabiliTrak is off and available
engine power is available for
maximum cornering speed. for
Use mode 5 for most consistent
performance during drag strip use.
When the TCS/StabiliTrak button is
pressed again, the vehicle exits
PTM mode and the TCS and
StabiliTrak systems are on.
Use Mode 5 for the most consistent
performance during drag strip use.

8. T/C & STABILITRAK OFF

Here's the best video I've seen on explaining the driving modes:




So which mode do you guys drive in the most?

I play around with "tour" and "sport" when I'm just driving around the street. Usually I just keep it in "tour." However the different PTM modes definitely help out. PTM 1 (wet) does actually help when it's raining. I can tell a big difference in PTM 3, 4 & 5 on the track. I usually autocross in PTM 4 or 5, and let me tell you PTM 5 will let you lose it. For actual track days I usually use PTM 3, especially if I'm not familiar with the track. once I get more familiar I'll play with 4. The PTM on the track in 3 or 4 is very cool, it will regulate just the right amount of power to make sure you have maximum traction in turns. Here's one of my videos from a track day and you can hear in some turns the exhaust kicking in and out (for example 0:17-0:20) that is the ECU feathering power to maximize grip through the turns.

Thanks for sharing.

I used PTM mode #3 at Streets of Willow CW last time out and I found it to be too restrictive around the corners....almost as if it was cutting power or torque....made it hard to have a fast corner exit speed.

It was my first time out on the track with the ZL1 so I didn't want to due something stupid. I just left it on PTM #3 but I think next time I'll move up to PTM #4 and she how the car handles.

Maybe I should mess around with the PTMs.

From my Z to my modded SS, everytime I start the car I hold down the buttons and turn of everything off.

Thumbs up

Good topic, KaBoom1701, thanks for starting the discussion. My new ZL1 just passed the 1,500 mile break-in. Have used Tour mode on the street almost exclusively. It would be nice if GM/Chevy would give more detailed information and descriptions on what parameters are monitored and what & how outputs are controlled, and to what degree, with each PTM setting. Would like to see their detailed design criteria outlined, but I suspect it's regarded as their private IP (intellectual property) and their trade secret for now, until it is released, leaked, or reverse-engineered.

This past weekend, Sat & Sun, I instructed at a Chuckwalla Valley Raceway HPDE and had a few instructor sessions on track in PTM3. Agree with you KaBoom1701, I felt PTM3 limit engine output in the corners carrying thru to the corner exits. Doubt corner throttle steering and significant car rotation is available when PTM3 is selected. Once the steering was unwound and car headed down the straights the engine "perked" back up.

Next track day in three weeks, back at CVR, I will move up to PTM4 and perhaps PTM5 depending on how it goes. Not yet ready for all the nannies off while driving with "anger" on track, or maybe never, won't know until I can determine the pluses and minuses.

I pretty much do the same as Baylor....

Great topic...99% of the time Im in tour mode without any PTM selected.

But I have a question I've wanted to ask regarding this for a while. In watching one of the videos in the sticky, the PTM mode will reduce torque & horsepower depending on which mode is selected. So the question (if I can word it right) is; does the ZL1 have all available horsepower and torque available when none of the PTMs are selected? Or is all horsepower and torque only available in PTM5 (#7 in KaBooms list)?

Thanks...

The power is always available, the car will detect certain circumstances and cut power. Everything is available only with the nannies off.

With all the nannies turned off you have no intervening controls reducing power with regards to steering angle, traction, and yaw rate.

I usually run in PTM 3 on the street unless the wife is riding or the road is rough then its PTM 2 and on wet and rainy days I like PTM 1.

I drive in Sport mode all the time. In the occasions that I used PTM3 and/or 4, I felt like that car didn't have as much torque.

aZL1, you worded this perfectly!

This was phase 2 of this topic.

It would be interested to know what PTM3 vs. TPM4 does when it comes to reducing engine HP or Torq.

Even if we knew the % of HP or Torq. reduction it think it we be good to know.

Anyone here have any Chevy Camaro engineers connections?

I use PTM 5 a lot because I like the tighter steering.
