Does turning off VSA (Vehicle Stability Assist) improve acceleration/performance?

Has anyone seen this article published on Edmunds.com website reviewing the 2017 Honda Ridgeline? Specifically the acceleration testing section.

https://www.edmunds.com/honda/ridgeline/2017//long-term-road-test/2017-honda-ridgeline-performance-tested.html

It’s an older article reviewing the “new” Ridgeline. They apparently spent a morning on their test track to test the difference between the G1 and G2 Ridgeline. The acceleration test (0-30, 0-45, 0-60, etc.) was done with and without the “traction control” on (I assume TC off means they turned off the VSA as there is no way to simply turn the TC off. Per the owner’s manual “The main function of the VSA® system is generally known as Electronic Stability Control (ESC). The system also includes a traction control function”) Per their testing, they reported a significant improvement in acceleration with the traction control off. (0-60mph - 6.9 seconds with the TC off vs 7.5 seconds with the TC on). All the other acceleration tests demonstrated better numbers with TC off as well.

Do you all think this is accurate/true??

I have been unable to find any other testing or reference to acceleration/performance of the Ridgeline with the TC (or VSA) off vs on.

After learning this, I’ve turned off the VSA at times and it seems to me that the throttle feels more responsive and the truck feels quicker. I don’t know if I’m just imagining it, or pushing the gas pedal down further/quicker. I haven’t done my own 0-60mph testing.

I’m wondering if any of you have tried turning off the VSA to see if you get a feel of improved acceleration (The VSA needs to be turned off each time you start the truck by pressing the VSA button…VSA is automatically turned back on next time truck is turned on).

If this is true, is there anything significantly negative to turning off the VSA when driving in good weather on streets/highways to get a bit of better acceleration/performance?

Usually better acceleration is achieved with traction control off because engine torque may be reduced at launch to eliminate wheel spin. With traction control off, tires are allowed to break loose and engine rpm is allowed to climb as quickly as capable for the vehicle gearing which achieves higher horsepower and torque quicker.

I doubt you would get quicker acceleration unless you are flooring it or torque loading by holding the brake at launch.

The fastest I have experienced the G2 is in SAND mode. Put it in it, wait for it to engage (3 sec), then floor it and hold on.
*** won't be good for the mpg's hahahah

...or the clutch packs in the iVTM-4 unit. :)

The clutch application is highest in sand mode. On dry pavement where the rear wheels are trying to turn 2.7% faster than the fronts, but can't, the clutches are generating tremendous amounts of heat and wear.

I would not classify my question to interested members of the ROC as concern or worry. I’m not drag racing for real money (or fake money for that matter either).

I enjoy driving my Ridgeline daily and feel it has pretty good speed/acceleration/performance for a pickup truck. I selected it for that reason and others. Having switched over from a sports car as my daily driver (for a multitude of reasons), I am looking to see if there were any interventions which could make the truck drive a bit more “sporty” (besides stripping weight, making significant modifications to the engine, etc). I don’t believe adding a sprint booster or any of the “performance chips” would work.

You may not experience them or realize it, but there are real world situations where a 0.4 -0.6 sec up to speed improvement can be very valuable (not to mention the experience a driver feels when driving a vehicle with that capability). The question is if the trade off of loss of the VSA/TC features is worth the gain in acceleration.

Thanks for your input but I’m really looking for others to comment who have actually tried this to see if they perceive improved acceleration in real world driving conditions or not.

Of course if there are other suggestions to make the Ridgeline drive more sporty as a daily driver I’d love to hear them.
