Guys, today I was stuck in the jam. Normally driving I would have around 6 bars of battery left (Full is 8 bars). So as I get stuck longer, it drops to 5 bars. Then all of a sudden later it drops to 1 bar which shocked me. After that as I move longer, the battery gets charged very fast and back to 6 bars.

Is this a normal thing? Do you guys encounter the same thing also?

I went back home and started revving the car to 3k RPM to charge the battery fully as I remembered that my SA actually said to do it 1 time every month which I actually forgot. It took quite sometime to actually rev from 7 bars to 8 bars. Does this have any relation to why the battery drops from 5 bars to 1 bar in few seconds?
*
One thing to note is that the IMA battery readout is not a real-time readout of the battery capacity. There will also be cases where slow drive or car park driving will deplete the IMA battery much faster, due to low rev ranges (IMA motor only helps at lower rev range to propel the car along). High speed runs actually charges the battery faster due to higher RPM on the stator magnets, thus you won't notice that the battery gets depleted. On the opposite end, the battery gets depleted at low rev ranges as the battery could not get charged back in time (low speed at the stator magnets), plus the constant use of the IMA motor to propel the car at low rev ranges.
For example, for my case, i will fully discharge the battery if I drive around Sunway Piramid's car park (just by searching 2 levels) and the auto-charge function will kick in whenever the car stops rolling (stationary). As long as there is no errors being displayed, the IMA is still functioning fine.
Second thing to note in case you are worried, is that the IMA fan have 2 speeds AFAIK, the high and the very high speed. The very high speed makes you think that there is a vacuum cleaner in your boot, but it disappears once the battery has been cooled down and re-charged.

Lastly, I do not see anywhere in the manual to ask us to fully recharge our IMA battery ourselves by revving the car to 3k rpm stationary, any idea if there's any reference materials besides the mechanic's "say-so"? I have never done it before, and don't plan to do it... it defeats the purpose of having a car if we have to constantly do this (hybrid some more, supposed to save the environment by reducing pollution). The main idea of the IMA is to re-cycle the kinetic energy which is normally lost during driving, thus improving fuel economy, but by revving the car stationary it sort of defeats that purpose. I would suggest instead that you enjoy your car every bit of the way... it is a really fun car to drive. thumbup.gif

Thanks for the advice too smile.gif Yeap, I don't rev it frequently . This is the first time I'm doing it after 3 months actually.
Thanks for the great info it, The reason why I actually rev it is because that it the battery actually dropped from 5 to 1 bar so it does makes me think that this is some kind of the problem where it was mentioned previously by some forum members which is knowledgeable in hybrid stating regarding the battery level of each batteries in the IMA.  . Reading some articles or forums had mentioned that Honda's IMA uses 6-8 batteries (the ones that you use in torch light) and there are possibility where the battery level are not equal. One battery might have full batt level and another might have low batt level. Thats the reason why it appears on our display showing the battery has only 1 bar left but in fact there is actually battery inside. As the battery levels of each battery are not equal, it would sent a wrong signal showing the status of the battery is low and therefore, it would disable the use of electric motor although there are still battery left inside. Therefore, I thought of revving the engine (which is the 1st time i ever did after receiving the car 3 months ago) to charge the IMA battery fully hoping that it would balance all the charge level of the batteries inside the IMA. Not sure if it does work to balance the level of each battery but just wanted to give it a try....l'm not sure if you or anyone here could understand what I'm trying to explain though as the knowledge I have for Honda's IMA system is very minimal. Apologise for that though. Another thing I notice is that as you rev the engine to charge the IMA, it actually heats up? Because i can hear the vacuum cleaner sound in my boot which means its trying to cool down the battery. Anyways, thanks for the great info though.
Please do share your results later, if it helps improve your CRZ battery charge holding. I am also interested to know too, ever since this "charge-while-stationary" thing came about from Honda SA. I would really like to know if it really helps.
AFAIK, not all battery packs are created equal, thus you will definitely get unequal battery level during normal usage. Small items like the voltage resistance at each contact point and the temperature can play a role to contribute to different battery level inside the IMA battery pack itself. FYI, CRZ have 7 battery packs, each pack contains a number of NiMH cells. With so many variables, I would think the battery levels will be different at the end of the day after driving, thus charging it after the end of your day will probably help re-level the battery packs. However, do note that the battery pack coverts the additional charge to heat if it is being overcharged, thus while waiting for other battery packs to be equalized to the same level, some packs may heat up since they are overcharged. Thus the fan gets really loud while you charge....

No Bro, I'm planning to install one myself too and Ive heard some comments about it. That is why I'm asking to see whether its really true lol. But previously when I wanted to buy the CR-Z , the Honda SA did mentioned something like this before too.

Go for Connex le.... dont have to meddle with pedal locks, which is, IMHO, is a bit too close for comfort in event of a head on crash (for guys) tongue.gif

Anyone mod the CRZ to gain extra hp?
Saw in rexxstyling some owner mod to 180hp..
Anyone know where to mod this?

It is Rexxstyling owner's car, bolt on turbo with 0.5bar boost if I am not mistaken (not too sure).
A few CRZ have done it already, try asking Avantgarde Motorsport as they have been working on one too.

Some thing that potential CRZ buyer should be aware of :
MITI to announce cuts

Not sure if it will affect the price of the CRZ or not, but no harm listening and asking later.....

No way.... as there's only one plant in Japan that produces the CRZ.
I suggest you change your SA. tongue.gif

No choice. It is a must.
My repayment is 1370. But I pay my dad 1k monthly.
When u guys go for servicing at honda SC, what engine oil u guys used on crz? Semi or fully? I plan to buy my own oil to service.
*
If I only have a 3K monthly salary, IMHO, I would not think of any cars above RM50,000k...
FYI, maintenance on the CRZ is not cheap... after monthly H&P, there is hardly any leeway for emergency cases. Then again, it looks like your family is helping you pay part of the car's H&P, so I guess you should be fine (no rental to pay, home-cooked food, not need to worry about electricity + water bills). Or go for side income, like what Ilyas have mentioned, it will help.
Always remember not to be slaves to the car, life's too short to be one smile.gif

As for the oil, Honda does not allow outside oil to be used at official Service Centers, or that is what they claim. If you know any of the Service Advisors, maybe they can do an exception on that rule (I have not met one). I use full syn engine oil on my CRZ, 5W-30 only. Honda's 0W-20 is way to thin for my liking thus I switch to use Torco 5W-30.

not convince with K20, how much hp can get out of it? if similar to FD2, then not much point, unless FD2R lo tongue.gif....
Some more, change engine... abit scary to me... too major, SC not so difficult. for me, a bit of boost enuf lor... not need fly to the moon. I think can get up to 160-70.. maybe by then the SCkits even more advance

I think Ilyas was referring to the K20A, the Civic Type-R version.

SC kits have more maintenance aspects than an engine swap (if it is done properly), and SC can also have overheating problems once pushed hard consistently. It is also pushing the boundaries of the 1.5L LEA engine capability to get 160-170hp out of it on the wheels (which means about 190 hp on the crank, I smell broken conrods and bent crankshafts), as the engine was never designed to deliver such power. You still have to think if the stock 6-speed gearbox can handle such power or not (burnt clutches are not uncommon on a Stage 1 supercharger), and the transmission of that power to the wheels (crank and driveshafts).

If you are thinking of getting about 160-170hp from the engine, it is much better for u to go for K20A, as you minimize issues related to the LEA engine & its parts. The parts on the LEA engine are designed to have a certain range of tolerance, but definitely not to 170hp.

So far. U guys ok with the air cond?
It's cut off when u r pressing brake. Does it still cold?

No I wasn't ok with it, and neither is the shut-down of the engine.
I hated the auto-stop so much I decided to kill it off..... kinda suck to have to sweat inside a nice car, and late take-off when the lights turn green (for the engine to start back up).

Yeap, I used the Pivot ISC.... installed it at JC Racing at Sunway.
Other methods never worked for me, including aircon etc etc... so i just got the ISC installed.

Yes it will, my car no longer have warranty anyway, i felt that outside mechanics treat me better than Honda tongue.gif
Anyway, ISC does not work with CVT cars, so its not a mod-path for your car unfortunately.

Is the auto-stop feature for the CR-Z really that annoying? My mom's 2012 Insight has it but it is not as bad as everyone says it is.

Personal preference.... one meat does not suit everyone.
I just don't like how the engine restarts itself at traffic lights or in traffic jams.

CF doors from Spoon are too hardcore already. Note the windows (plexiglass) cannot be used, and you get a small opening at the driver side. Not to mention the car's NVH can be thrown out of the window too. Think it is only meant for track, as side impact protection is virtually non-existent for the CF doors.

someone tried pumping vpower full tank once, he said can't even feel much of a difference as the acceleration mainly comes from the battery.
*
My dyno runs using my CRZ (while tuning for Hondata) shows that RON97 indeed gives more power on the CRZ. That is why I decide to stick with RON97. Also note that the engine does not increase power immediately after pumping RON97, as the ECU needs some time to increase the ignition timing and re-optimize for the new fuel, unless you use Hondata and switch over to a program that is optimized for RON97.
BTW, normal Shell V-power RON97 is terrible based on my experience, I only use V-Power Racing if I m feeling rich, else it would be Petronas RON97 or Petron 97.

If wife rejects the car, my suggestion is to listen to your wife. IMHO, you don't want to end up in a situation where she says "I told you so". Trust me, you'd never hear the end of it till you die. laugh.gif
I drive a CRZ, however, I also have other cars to appease the Lord-at-Home, thus if you are planning for one car only, I would suggest a 4 door car.
