    Most useful MG4 accessory?

    Just another reason not to kill even more aero with worse wheels. It's difficult to actually measure the difference in real world, but the difference is there. Otherwise manufactureres wouldn't bother covering them up.

    Most useful MG4 accessory?

    that's actually a common misconception. Aerodynamic properties of the wheel and wideness of tire play a significant role in consumption. For example; tesla3 lr rws drops almost 10% of WLTP range when you upgrade to 19" wheels with more open design. And the faster you drive, the more effect...

    What LEDs did you buy? Do note, that those open wheels will kill a lot of range. Not a very good thing when the car already has pretty small battery.

    DAB+ is still spotty, so is deceting poor lane markers. But it's better than what it was originally.

    MG4 Battery Health

    As mentioned above; at least for LFP car's the most accurate value seems to be to reset the board computer and check estimated range at 100%. That compared to WLTP range will give you an indication of actual degradation. NMC cars seem to already report pretty accurate value from the carscanner.

    State of health does affect that, but under normal driving conditions, you're not gonna be power limited until the battery is severly degraded.

    MG4 Battery Health

    I'd still say, that driving just like the rest of trucks isn't a bad thing though. As long as you stick to that and don't drive slow when there's no trucks or on the passing lane. But yeah, not a good image for EVs for sure.

    This is just to remove as much variables as possible. In real life, you just don't drive like that, as it's a pain obviously.

    MG4 Battery Health

    Both datas are relevant, because you can easily calculate available full charge energy of the battery. And thus calculate real SOH. The problem with picking a longer journy is that there is just way way too much variables at play to say if the battery is still the same or not. You might do that...

    As a driver you can fully charge the car + balance. And when the car is fully charged, immediatly go for a drive and run the battery completly. Resulting milage and consumption (along with energy spent on that trip) will give you a very nice indication on the actual energy battery has.

    Clicking sound from brake pedal

    Were you able to fix it? Seems to have the same sound from mine as well.

    Of course you can measure SOH. Very accuratly at that. Top charge to 100%+balance and then discharge to empty empty (BMS cuts off due to low voltage). The resulting discharged energy is your actual pack capacity. Actual pack capacity divided by nominal new pack = SOH in %. And BMS can...

    Maybe NMC cars are different. Im pretty sure LFP cars, when you reset the consumption, range estimation defaults to WLTP minus degradation.

    MG4 Battery Health

    don't give too much stock into this info. If you want to get real degradation (or close to it) reset board computer and check the range. Your actual range divided by WLTP range of your car will give you a better idea of degradation. My suspesion is, that 51kWh cars include bottom buffer into...

    Diagnostic VDI, VNCI, MDI with MG4

    Not possible, at least not with public tools currently available. Would be nice though. Disabling things like TPMS, seat belt reminder, LKA would be hella nice.

    I can confirm, that SE R40 is pretty good on bluetooth as well! Hopefully it stays that way.

    Will upgrade all speakers and add a sub

    Just a tip; since the infotainment allows for app sideloading; you can install poweramp equalizer and have a much better EQ tuning options compared to stock. Just remember to enable "global eq" in the settings for it to actually work.

    You can use ABRP without a dongle. If you have homeassistant (or any other linux based server) you can install saic-mqtt-bridge and feed your car data directly to ABRP via it's developer id. Much more reliable and convinient than a dongle. And to top it all off, you can map ABRP to one of the...
