ECT button vs. ShiftSense Pro V2

2019 TRD OR, automatic, doublecab

Fellas - Just because it's fun to spend money on the truck, I've been dabbling with the idea of getting a ShiftSense Pro V2 to see what sort of performance changes (smoothness?) that unit could provide. My truck does on occasion hunt for gears and do the weird shifting, stutter that some describe. That said, when the ECT button is pushed, most issues evaporate and I get a nice smooth throttle response rather than the delayed "...oh wait, you want me to do something?..." pedal push.

For those who have played with the ShiftSense Pro V2, does it buy you much more than what the ECT button provides? Any information you can share would be appreciated.

I've had ShiftSense Pro V2 for 3 years. I think it works great, but I am considering OV tune soon for better performance and some other tweaks. would recommend.

 

SprintBoosterV3 here and ECT on Dig it. No regrats.

 

Do yourself a favor, OP, get your truck tuned. Smiles for miles they say!

 

if you have a v6, you can get a tune.

 

From ShiftSense FAQ...

How do the shift-mappings differ from OEM and ECT options?ShiftSense™ Pro shift-mappings differ significantly from the OEM and ECT shift-maps. Maps are established based primarily on speed/throttle position combinations. The stock shift-maps for the Gen3 Tacoma resemble exponential slope curves, which extend to very low speed at low throttle positions. That is the reason it shifts up so early. On the other hand, these same stock curves go to very high speed at high throttle position, hence the need to 'floor it' to get it to accelerate normally. ECT mode is slightly different in that it indexes the stock shift curves up by several MPH, but they still maintain the 'exponential' slope which is not a good match for many driving conditions. The ShiftSense™ Pro uses a more linear shift-map, which provides shifts at higher speeds for low throttle positions, and greatly limits the amount of up-shifting at low-speed conditions.



Equally important to the 'shift mapping' itself, is the ability of the device to hold gears for certain driving situations, select the proper gear for cruising speeds, and perform appropriate downshifting during deceleration and braking. These criteria are extremely important to the overall shifting performance and 'feel', and have been refined in the ShiftSense™ Pro based on extensive testing. In modern vehicles, 'drive-by-wire' has replaced the mechanical connection between the driver, throttle, and transmission by a computer. The ShiftSense Pro relies primarily on accelerator position for shifting calculations, therefore, it effectively re-establishes this 'link' between driver's foot and transmission control.
The ShiftSense™ Pro includes a shift map for normal operation as well as a slightly reduced map for cold operations while the engine is warming up (engine temps <150F). This coincides with the vehicle's stock torque-convertor operation which is prevented from lock-up if the engine temp is less than 158F.

 

Thanks everyone for the replies. I'm sure I can find this elsewhere, but since we are on the topic, does OVtune void out any warranties? I've already lost a few with the suspension and driving bits by adding a lift and would like to avoid losing any other coverage, if possible. From other members, it seems that most that play with the ShiftSense end up graduating to OVtune. ShiftSense seems to be the step #1, low dollar, performance mod, with OVtune being the holy grail. Someone correct me if I'm wrong?

Thanks again for the input and help.

In my opinion, for around $300, going with a tune is the best option. The tune is not detectable but if you are concerned for whatever reason, you could always flash back to stock.

Take a look the below thread. You may find all your answers there.

Thanks, all. I just nabbed a ShiftSense Pro from eBay for $70. I'll give that a go for now, but keep OVtune in my back pocket for future. Again, thanks everyone who responded. Best, MJA
