For the 2016 and up Honda Pilot, although Honda is marketing its AWD system as “i-VTM4”, it is in fact identical to the latest SH-AWD.
So I thought there is some difference is the SH-AWD that the current MDX is using compared to iVTM4 current Pilot/Ridgeline? I have loaner 2015 3.5L 290HP TLX SH-AWD while my old 00 3.2TL is at dealers. So what's difference in it from Ridgeline with iVTM4.Interesting read. I always explained to others that the AWD system on the Ridgeline was the same as SH-AWD found in the Acura even though I was not 100% sure. It's just that everyone has heard of SH-AWD and it makes more sense and a good comparison for understanding. Looks like I was right after all.
I do not agree a truck is typically bought to off road more so to load and haul some of the time unless purchase for commercial use. I would like to see a survey of how many trucks actually do off road in a way that a true 4x4 system would be a better choice. My guess is a measly 5% and I am being generous.it's got a really nice AWD for pavement, but it's a truck chassis, typically bought to do truck things (off-road etc)
I'd argue its more a slip and grip transfer of torque from front to rear.So its not a FWD biased system like many have claimed.
Not really. I downloaded and read the SAE presentation that Honda gave on the system. The only time it goes into FWD mode is during coasting and braking, in order to save gas. The rest of the time there is some power being applied to the rear wheels, 10% during cruising, and more during acceleration (even in a straight line). I think it is fair to say that it really is a full-time system.So its not a FWD biased system like many have claimed.
Trucks are inherently terrible at any sort of real off-roading. They have terrible break over and departure angles, both of which are essential in any real off-road situation.I do not agree a truck is typically bought to off road more so to load and haul some of the time unless purchase for commercial use.

Honda doesn't want a Honda product having the same features of an Acura. It dilutes the Acura brand image.Why would the Truck NOT have the most aggressive torque vectoring software? Considering a truck should be "MORE" capable than a crossover type vehicle...
Now my question is: Is it possible to update the software to use the MORE aggressive torque vectoring software?
I would totally be willing to try it.
Cruise controls modules disappeared with mechanical throttle linkages years ago.Honda doesn't want a Honda product having the same features of an Acura. It dilutes the Acura brand image.
The G2 has the same cruise control module as the MDX, but the slow speed follow feature is disabled because they want Acura to have something Honda doesn't. The logic is there, but just disabled.
As far as modifying the software... I won't say it's impossible but it would take someone like Hondata to do it... and as far as I know they don't do much that Honda doesn't want them to do.
I actually have no idea where the cruise control logic is held. I just used the term cruise control module in error. I was paraphrasing a conversation about the issue about the slow follow feature. The bottom line is that all the hardware is already there on the Ridgeline to enable the feature, but to preserve the Acura brand image they won't enable the feature on the Ridgeline.Cruise controls modules disappeared with mechanical throttle linkages years ago.
The various sensors like the camera and radar unit must somehow communicate with the PCM, ABS, and power steering instead to control acceleration, braking, and steering, respectively. Does Honda use a dedicated "Honda Sensing computer" for all these functions or do the sensors communicate directly with the system that needs to be controlled?
The current iVTM-4 and SH-AWD systems are mechanically identical, but the logic is different. The SH-AWD system is programmed for more aggressive torque vectoring than iVTM-4. The difference is in the software.
I'm responding to this old thread because a new video was published today on the subject.Why would the Truck NOT have the most aggressive torque vectoring software? Considering a truck should be "MORE" capable than a crossover type vehicle...
