Boost 50

Not interested in the 50hp boost, I struggle to use the >300 kW the car has as standard - my record so far is to hold over 300 kW for just under 3 seconds, and that takes a fair bit of doing (I play a game to see how much power I can put down in one continuous period, as recorded by Teslamate - childish, I know . . .).

However, looking down the features of this dongle, the one I've highlighted in their list (in red), copied below, jumps out as being very useful, and worthy of more investigation:

PERFORMANCE IMPROVEMENT

The Boost 50 module increases the performance of the Tesla Model 3 Dual, without the "Performance" option.

  • Acceleration time for Model 3 from 0 to 60 mph : 3.7 seconds
  • Total power: increase of 50 HP
  • Improves throttle sensitivity: reduced response time
  • Heated rear seat control with web application or rear window switches
  • Ambient lights
  • Automatic driver door opening
  • Automatic frunk and trunk opening with proximity sensors*
  • Drift mode (a special driving mode that disables traction control but maintains ABS and power Steering)
  • Battery pack heating
  • Manual wiper control
  • Blocks TPMS alerts (BLE)
  • Live data: battery pack state of health, beginning of life pack energy, full nominal pack energy, isolation resistance of the battery, HV battery voltage/current, LV battery voltage/current, battery and charger temperature
  • You'll still have access to Tesla's firmware updates

If this module can provide manual wiper control, then that opens up the possibility of other third party modules being able to do the same, perhaps providing enhanced user interface functionality to other controls, like the lights, as well, and maybe improving the lack of sensitivity with the left stalk control (I find it often takes two or three goes to get the lights to switch back to main beam from dip, for example). Might be worth contacting the developer to find out more, perhaps.

Edited to add:

Just spotted they do a cheaper (but still far from cheap) module that doesn't do the performance boost but does have manual wiper control:

BONUS Module - For Tesla Model 3
 
Any purchaser or user of the Boost 50 module releases Technologies Ingenext and all its related companies from any responsibility regarding the full or partial validity of the manufacturer's warranty following the use of this equipment. We are not responsible for any modifications the manufacturer could do to your car (ex: turning off some features etc.).

Wouldn't touch it with a bargepole while I was in warranty.

Also this - Tesla fights back against owners hacking their cars to unlock performance boost - Electrek - suggests Tesla can detect it.
 
Just been digging into the Bonus Module functionality (not the Boost Module). It does indeed add full manual control for the wipers. It's activated by pressing the wash/wipe button, then the headlight main/dip switch becomes the wiper control for a few seconds, allowing the wipers to be turned on, off, adjust their speed, etc. Seems a brilliant idea - just need to persuade Tesla to add it as an option.

BONUS Module - For Tesla Model 3

Indeed, these other options are almost as good as an extra 50hp :)

Particularly like the auto door opening, battery heating and manual wipers.

Throttle response improvements also good - I had this on previous cars (VW), through a "pedal box" which did the same thing.
 
This boost is faster on road tests and half the price...
But you gamble with your warranty. That's the price of it being cheaper. Only you can know if it's worth the risk tbh.

If it was a Skyline or something I probably wouldn't think twice, because I'd be using specialists anyway, and the car isn't "smart", but it's reasonable to conclude that Teslas are phoning home pretty regularly, so it is reasonable that diagnostics data might find its way back there too and you end up with a car with the Tesla equivalent of the Audi TD1 code

How does automatic door opening work on a Model 3 when it doesn't have actuators to do that?

Sure, it's a fair point.

Every "enthusiast" type of car has after-market upgrades... I've tuned/chipped Golf R's, Audi S4 in the past, all within warranty and no issues. Friend of mine had an early turbo go bang in a Golf R mk7 whilst chipped... replaced under warranty.

However the tech is much more advanced with Tesla... I'd be surprised if they couldn't "detect" it somehow. The article above I posted references to finding the unit through a "separate communications channel" - which is rumoured to be via a supercharger! Interesting to think that the car would exchange detailed info via a supercharger but Tesla's are so advanced, anything is possible.

Ref the Audi TD1 code - the workaround was always the tuning box and it's post the sensors - I wonder if this "nice try module" does something similar.

Anyway all interesting stuff for the enthusiasts!

Auto door opening appears to work via bluetooth proximity detection - same as your nhs covid app!
 
My TTRS was mapped too, and had warranty work done (only one job on the engine though, Haldex issues) without them flagging it or even raising it as a potential issue.

That being said, I did keep a slush fund handy on the basis that if something significant went wrong they'd probably investigate it more and if it was anything engine related they'd probably kick it back.
 
Ah right, yeah. Looking at @Medved_77 's video above, it looks like it basically does what the handle tells the car to do when you push it in, i.e. release the door. I was thinking more like Model X where it fully presents :)

IDK.... I'd be worried about a gust of wind catching the door and taking it back on the check strap or a post, parked car, etc. I assume the actuator/motor in the X can handle this. But I guess I'd be more worried about the possible affect on warranty. Some nice features though! Like the idea of wiper control - Tesla really need to do this!
 
Compare this from the boost's website:
Any purchaser or user of the Bonus module releases Technologies Ingenext and all its related companies from any responsibility regarding the full or partial validity of the manufacturer's warranty following the use of this equipment. We are not responsible for any modifications the manufacturer could do to your car (ex: turning off some features etc.).

with this, from superchips/bluefin for a 'chip' of an ICE car:
Summary of cover
Mechanical or Electrical Breakdown:

Being the sudden and unforeseen failure of a component of the Motor Vehicle directly attributable to the operating of the Superchip the subject of this Warranty, which has caused the Motor Vehicle to stop working and therefore requiring repair or replacement before normal operation can be resumed.
(taken from Superchips warranty for petrol and diesel engine tuning, ECU remap software for maximum driving pleasure.). Basically covers the situation that the dealer says no to something 'because you chipped it' - way I saw it with the last car was superchips would either fix the problem or lawyer up on my behalf. Peace of mind all round.

I'd take the tesla one if I didn't have a P-, thanks.[/quote][/quote]
