Turn off AC and just let it be in fan , it would last about 15 minutes

Yesterday , I've managed to get 5/6 battery bars. Trying to get 6/6
IMHO the CBU unit is still better , rear disc brakes , 6 airbags , auto headlight (and even auto leveling i think) + auto wipers , better/softer materials
*
I don' think you can get 6/6 unless you are coasting downhill. Please be aware that regen braking will not function when fully charged at 6/6. Not sure how that will affect the braking feel, but something to watch out for.
Excerpt here.
QUOTE
If the battery is fully charged, the regenerative brake can not be used and the pseudo engine brake will not work, so it is unreasonable for the engine to turn while descending downhill, but you can travel EV even if you step on the accelerator slightly I feel that it is in vain that the engine keeps turning.


Here's a chart stolen from here as usual. Left chart is JDM pre-2014 recall. Right chart is after JDM 2014 recall. We are probably using Right chart.
When we just reach 4/6 bars, we are only half way there. 5/6 bars is where you wanna dump the power it into SPEEEEEED or you could just slowly discharge it at 90km/h.

Will you retain the stock HU or do you have plan to upgrade it to a better Apple car Play or Android Auto

How about the sound and  speaker quality
*
I'll keep the stock HU for now

Sound and speaker is meh , seriously it's a joke. My fiesta had better sound system , it's like super duper bad. Proton cars do have better speakers to be honest

Maybe the V spec gets better speakers , I don't know but the hybrid one is pretty meh

From the short 10 minutes time I had with the 6 speaker config, if I recall correctly, it's pretty much the same... I guess the front pillar speakers are too soft to make any impact on clarity/presence... voices are still coming from the A/C controls hmm.gif

Pre FL 30% highway 70% city

But always speed on highway.

17' rims but much more lighter than 16' Honda City's rims

pulse and glide , you need to learn how to hypermile

https://www.youtube.com/watch?v=wM2kTfFLi0o

I do that at highways , of course - you need to drive on a slow lane and make sure you are not annoying people at the back. Generally , I would pulse until say 80 or 90 and let it glide till 80 or 70 km/h and rinse and repeat

This way I can save a lot of fuel. You should try that

Oh hey that's my acceleration...
He's on manual, and shifts to neutral gear to glide(I think I heard him say "See no gear" @ 0:40), so there's no transmission loss for him (someone correct me). Dangerous guy.
Us EV guys have a different method.

Nah my V-spec pre-FL speaker is lousy. Changed it after a month.

Thought of a plan to fix the crappy HU sound system without removing anything. 100% end user plug and play... Will order stuff and report in a few weeks...
*
So, here's what I've done, then gave up on but it semi-works without replacing anything in the car.
I was mainly aiming to polish sheit into bronze, not shiet into gold, so it kinda works.
Do note, this is not the conventional way to get better sound quality.
This is figuratively shoving a square into a circle and you get squared circles, or rounded squares. Whatever.
Point is, am forcing stock speakers to behave like other speakers.

Equipment Used:
Phone [3.5mm AUX] -> [3.5mm AUX to RCA] MiniDSP [RCA to 3.5mm AUX] -> [3.5mm AUX] BT Transmitter [Bluetooth] -> [Bluetooth] Head Unit
Those who see the hardware and roughly know what I'm trying to do with the hardware above, just skip cause you already know it won't work proper. thumbsup.gif

Pros:
80% match my reference (AFTER a little +1/2dB EQ bump with phone *sigh*)
Head unit saves volume profile across Sources (AM/FM1/FM2/BT) so can safely change source without changing volume.
Cost??Maybe?? (I haven't scouted the price of amplifier+crossovered tweeters+installation yet unsure.gif )
BT takes over "Media Audio" profile only. You still can route phone calls to phone.
Blind test puts a smile on your face on how much improvement it got compared to stock... then you cross check with your reference... and cry.gif but keep at it bruce.gif , it'll shine abit more, then you'll realise you've hit that limit and continue cry.gif

Cons:
Soundstage/imaging located at top part of steering wheel which still sucks. Probably due to lack of tweeter/front speaker. Need hardware upgrade to fix which may void warranty (idk) and fork out more $$$.
Startup procedure is pain in the ass due to old ass bluetooth version pairing, but mainly because Honda Malaysia skimped on a <RM2 AUX connector for god knows what reason bangwall.gif
-Power up car > Turn on BT Device > on the HU, go to Bluetooth Audio > Settings > Connect Bluetooth Audio > Select BT device > on BT device, Trigger Rejoin procedure > immediately on HU click Connect icon > Exit main screen
Can't control Previous/Next track due to 3.5mm AUX.
Still need to tune with phone equaliser. (may be avoided, just need to spend extra few more hours or so)
Noise from BT transmitter can be heard at quiet parts of the song. Hissssssss. Like those AUX to FM transmitter noise. (This is gain-staging problem, MiniDSP mainly cuts dB to match house curve. You can try set Bass -5 on HU to so MiniDSP doesn't reduce gains so much, just an idea.)
Uses 2 USB ports to power MiniDSP and BT Transmitter. So you probably need a 12V to 3x/4x USB and a good quality or modern one. (1x charge phone + 1x dashcam)
--If you cheap out on 12V to USB socket (ones that use cheapo 50sen MC34063 ICs), both, BT transmitter and MiniDSP will cause a lot of noise.
----To fix BT transmitter noise, you can solder extra SMD 50V 10nF+10uF+10uF (space constraint) on BOTH input and output side tank capacitors. Solder them between the through hole electro cap legs. --BT transmitter has internal battery (most have it at least), so it will draw a light load current from the regulator, thus no noise. MiniDSP pulls too much current and it screeches.

Wires. Dem freaking wires everywhere. 2 AUX + 2 USB going from 12V to armrest.
Can't cast because casting forces audio routing to end device. (I think?) That means no 'Waze on the big screen'. Boo hoo.
No album art info & display. But FL HU already don't work proper ¯\_(ツ)_/¯

Total damage:
USD $105 MiniDSP DSP hardware
USD $10 MiniDSP DSP software
USD $75 UMIK-1 calibrated mic (optional, you can do it by ear if you trust yourself, or you can do it the old way, RTA/ear+pink noise)
~RM9 3.5mm -> RCA
~RM0/RM9 RCA -> 3.5mm (BT Transmitter should provide it)
RM60/140 Bluetooth transmitter (~RM60 if you can wait for 1 month shipping from China, ~RM140 ship in 3 days)
RM??? 12V to 3/4 port USB charger. (Had one lying around, since 6 years ago. In the car. Under the sun. It didn't explode. Yet.)
Lots and lots of reading and trying to understand and actually doing by experimenting and failing.
Time.
Fuel because A/C due to Weather hot and humid AF, everytime, everyday.

Coming this November, my Jazz will be two years old....though its under utilised, still need for windscreen coverage....the previous coverage is only up to RM1k only ? Is it enough ? Anybody have any idea on the actual replacement cost for the original windscreen ? Can cover the tinted cost as well?
