Hi, I just accidentally find something interesting range extender. Does anyone mx-30 electric owner have experiences about any range extender chips?
It is quite interesting thing if it works well. There is days sometimes when need to drive motorways more than usually and even little bit larger range would be great.

If you read my discussion again and think a little bit of it, you may understand that I don't ask your oppinion but I ask if someone have experience of it, I think it is more joke if you run out of battery. And if you click that link you might see that it hadve option to switch between different settings.
And ofcourse I would like that is faster but some situations it prior to drive longer.

I have sent them an email asking for the installation instructions to see what is involved before considering an order. I am aware, as you no doubt are, that the dealer may see this installation on obd data and could affect warranty. I will cross that particular bridge if and when I see how easy it is to install and remove. I, like yourself, am more interested in the range not necessarily speed. As you state it would be good to know how other vehicle displays etc. are impacted. Does it show additional range on car display, would the kwh/km for example push it up on the display etc. Good find but as you state more actual user info would be most helpful.

Seems like it just tweaks down the signal sent from the accelerator pedal, i would say given the additional range figure somewhere around 10%

Would also be non-trivial to fit in a Mazda given the pedal is bottom-hinged, I think you have to remove the whole pedal to get to the sensor

Baz, let's wait and see. They do state it is a simple installation that can be done without technical knowledge. Could it simply plug into the odb socket? Who knows hence the wait and 👀

The instructions are on the website - disconnect the throttle signal cable and attach the box inline to the terminals, then fasten it into the footwell - but you can't do that easily in a Mazda

Baz, yip I seen that and the youtube video but wondered if it was generic instruction. You would hope as that it states " increased comfort by balancing other electrical consumption" it is more than just a pedal sensor. It could be I am reading too much into it (probably true!!) but who knows as they could just be saying less drive consumption equates to more power for other HV draw components..

Also as it says easy installation you hope they would have tested the installation and made it plug and play without pedal removal.

Who knows and I suspect you are correct but I await the mx30 specific instructions 🤞

My guess is it smooths out the acceleration spikes and provides a more linear signal to the drive train. If you think about it, the motor will need the same amount of power draw to maintain, say 60km per hour, as before so no change in that respect. However it may take longer to get there in my opinion. It is only fitted to the accelerator pedal hence my guess on the more linear signal.

I feel obliged to offer this warning:

The automotive industry is extremely regulated, and if anything goes wrong with their vehicle which endangers the life of the vehicle occupants or other road users they are liable.

This is just my opinion, but it comes from someone who has designed and built mission/safety critical embedded microelectronic systems: Do not interfere with the control systems of your car, and definitely don't trust your life and the lives of others to a third party component which will not have been through the rigorous testing and legal requirements of the car's original systems.

Likely this "box" will probably be built around a cheap ESP32 (probably a consumer standard unit, not an industrial or automotive standard), which could fail at any time due to extreme environmental conditions, the software will have been coded to an unknown standard by an anonymous coder, with unknown edge and corner cases, and the full range of interactions with the rest of the vehicle systems will not have been fully tested.

If you want more range, the best way is to learn how driving style, loading, and route planning affect the power usage of your vehicle.

Apologies for the ranty nature of this post, but cars are dangerous.

-Edit- Also reading the web site, it appears all this thing does is reduce the apparent position of the throttle peddle... I don't need to spend the better part of £300 just to be a bit lighter on the "gas"... Also have you tired the cruise control limiter?

H5n1xp, I bet you are glad you got that off your chest. Good advice but there will always be people modding outwith the manufacturer regs and taking the associated risk. At least you have put it in stark terms. To be clear it does not physically adjust the pedal position but takes the pedal signal and "Adjusts it" according to how I read it. You disconnect the throttle connection and replace it one connector from the chip box. You take the plug you have removed and connect it to the other chip box connector. So all it is doing is playing with the throttle sensor signal. As you point out if this fails who knows what it will do, for example full throttle with no control🤯. And your warranty will be screwed as the mod will show up on the obd data feed!

p.s as may be your insurance :poop:

The risk most definitely outweighs the benefits
