Etorque Sensitivity

[Wifuop60]

I was just wondering if anyone else has to take of from a stop like your driving with an egg under the accelerator to prevent chirping the tires. I have good tires on the truck.
If there is any kind of moisture on the road I will spin the tires even when babying it.

Mine works good but I usually have it off ( Tazer ). Maybe that right foot is just to heavy. lol

if i'm not mistaken, the etorque system only activates whenever the vehicle is coming back on after auto start stop. not every single time you accelerate from a dead stop.

Take foot off brake. Truck starts. Accelerate. Takes a bit of practice.

The system does add torque for the first half turn of the wheels according to videos that were regularly circulated when 5th gens first came out with etorque.

I have to be careful with my Rebel. 3.90 rear gear combined with that low first gear in the A8 makes for plenty of torque. Also have the eTorque system but that has nothing to do with it on my truck.

The eTorque system does provide some torque on engine start, but not once the engine is running. It would come into play when switching from brake to gas quickly. In what for me is normal driving, there is enough time between when I lift my foot off the brake and move over to the gas pedal for the engine to already be running. I bet if I did it real fast, I would just burn rubber due to a bit much gas pedal.

Set your rear tire pressure to 32 to 35 pounds.

Perhaps you mis-spoke. Etorque provides no torque on engine start but does add torque on take-off.

There is a lot of misinformation that's thrown around in forums. I would encourage anyone who really wants to understand how the system works to search the web for any of the dozens of articles and videos which explain it, and avoid forums for that information because of the contradictory information that exists in them.

My understanding when I watched those videos, is that only occurred after the Start/Stop.

From what I read/watched, the only help the eTorque gives while driving is making the transmission shifts more smooth.

This video explains it pretty well if you have 6 minutes...

Seems a mix of I mis-spoke and mis-understood as to how the system works. The video is a clearer explanation than what I wrote, and it does provide more torque to the road in the early rev pulling away from a stop sign. The video shows it does so for longer than I understood it to provide the electric boost.

this is what i was trying to explain, when turning back on from a auto start stop cycle.

It’s not just after an auto start stop cycle. For instance, if you disable stop/start the etorque motor/generator adds torque when taking off from a stop. Disabling stop/start does not disable the other features of etorque.

Agree. For instance if the AC system can not keep up so auto-start (stop/start) is disabled, the system does still provide some additional torque off the line. Almost never happens for me unless I set the system to max cooling.

As part of my earlier comments, was wondering about the axle ratio for the original question. I have 3.90:1 and the A8 has such a low 1st gear, the combination already has a lot of torque. I do have to be careful getting off the line, especially if I am making a right turn and there is loose stuff like gravel on the ground. I spin tires pretty easily. Not sure how much eTorque contributes but any amount is on top of what the Hemi already has. I do pretty much drive like I have a raw egg under my right foot.
