Toyota Innova Owners & Discussions [continued]

[liv]

ano pong ibig sabihin ninyo?

mga naka experience po ng hard starting, choking, stalling, black smoke problems ang ilang 2005-2008 models ng Innova.

The ECU records how much air you get, to proportion how much fuel to inject. After combustion, it measures the oxygen content in the exhaust gasses to further tune and find the appropriate most efficient fuel-air mixture. This system is not as dynamic as we think, the ECU usually takes time to completely adjust since there are historical data logged in it from your previous use. In this case, the fuel management settings being used by your engine now is partly based on your previous usage which is with non-v-power diesel, therefore confusing the ECU and knocking almost perfect air-fuel mixture out of proportion. When out of proportion, two things will happen:

a. Lean (more air less fuel) = This tends you to give you lesser power which in return makes you push the pedal harder. This results the same speed but twice the effort for the engine.

b. Rich (more fuel less air) = This tends you to give you more power since you have more fuel coming in the combustion chamber. But you are actually wasting fuel because not all the fuel is being used up due to the lack of air. Biggest waste is when at idle.

Resetting the ECU erases previous data logs and the ECU gets to memorize the new setting for the new fuel you have for a near-perfect air-fuel mixture.

Hope I explained it well.

how does an ECU being resetted? before we go on far, too; what is an ECU?

Hindi yan grounded bro. Kulang ka sa ground... pa check mo sa toyota service advisor mo baka may body/chassis ground silang hindi nabalik. pag pinagtagal mo yan kahit hindi ka pa gumamit ng wiper, yari box mo dyan.

Thanks for the info sir, tama ka merong wire na hindi nalagay ng maayos then nag lagay sya ng additional ground wire. Sa may chassis at may loose wire sa dash board.

ka bad trip ang CASA. ano kaya ang sagot ng casa kung nasira nila ang computer box dahil sa kagagawan nila?

1.) yung di maayos ang pagbalik siguro ng wire nong nag palinis ako ng aircon at full detailing (exterior, interior at engine detailing.)
2.) di maayos pag lahay nila ng host ng aircon nabasa ang carpet ko nong nagpa remove carpet ako para linisan.

Nung bumili ako ng 2.0 na sasakyan, expected ko na mas mataas ang consumption nito kesa my Civic Lxi. Kelangan ko nga lang baguhin ang driving habit ko, alam nyo naman kung gano kaganda ang tunog ng honda pag binomba ang silinyador. :D

Hindi din dapat basta basta nilalagay sa neutral. You can coast ONLY if you will do a full stop (or less than 10kph) at the end of the coast. Otherwise, dagdag wear and tear lang yan sa transmission.

Haha! buti na lang umulan paps at nagkaron ng symptoms when using your wiper. Kundi, baka nayari yung box mo... that's why it really helps to install grounding kits. No need to buy, you can actually make your own grounding kits. Just buy a gauge 12 wire and some 10mm terminals, solder them together and install! Big help specially sa mga computer aided cars like ours.

how does an ECU being resetted? before we go on far, too; what is an ECU?

ECU is the engine control unit or the computer box. You can reset it by removing both battery terminals (positive and negative) while engine is cold (before using the car after a long rest like in the morning). Keep the terminals detached for 10 minutes then re-attach. Start engine and let it reach normal operating temperature (which is half of the gauge) at idle. When reached normal operating temperature, you may use the car na. Na-reset na sya nun. Some reminders though:
1. always remove terminals negative first
2. always re-attach terminals positive first
3. never turn-on any electric accessory while engine is running idle until normal operating temperature is achieved.
4. always do the reset when tuning-up or at least once a month.

Last tip to the fuel consumption conscious:

Always run with your car with fuel levels at least half of a tank. This ensures no air bubbles accumulate in the fuel lines and maintain the power efficiency your car. Because for example, your on a steep hill and your running with the fuel icon lighted up, chances are when you hit a pothole or a bump on the way up, the fuel inside gets to shake then the fuel pump might get to suck empty air instead of fuel which will lead to an air bubble in the fuel line. An air bubble in the fuel line causes misfire therefore loss of power for that particular stroke which makes you push the pedal harder which results to more fuel consumed.

Share ko lang nangyari sa gulong ko kaninang madaling araw while driving high speed sa NLEX. Buti nalang di nawalan ng control sasakyan. Sana palitan ito ng Yokohama.

Good thing nothing bad happened to you bro... ang sarap din kase patakbuhin ng Innova. I still have one myself. My friends and I call these Yokohamas: Yokohohoys! Sa ganyang sitwasyon, Pot*, mapapa "Hohoooooy susmaryosep!" ka talaga sa takot! Looking at the picture you posted, I noticed a lump right below the characters "/65". Yokohohoys have a high percentage of coming out with notoriously defective tires (at least basing it from my experience-100%). Nagbubukol bukol sa sidewall madalas. Well, the best thing to find out what happened to it really is to bring the tire back to them and have it inspected. Just pray and hope that you get a favorable decision from them. You know what? You deserve to get back at least a pair from ayokohama. Kilos gobyerno! Puro... anak ng jueteng!

Nagka bad experience na din kami dyan sir sa Yokohama, yung Super Digger V nila. Nakakabit sa lumang Trooper. Ayun. 4 out of 4 tires nagka bubble sa pisngi.

Yung sa innova namin naubos naman yung tread ng 4 tires without incident. Pero madulas talaga yang stock tires ng Innova na Yokohama. Pag brake mo parang progressive ang pakiramdam, parang kakagat pa ng mas malakas as you press the brake pedal further pero it never does, hehe. Marami na din akong close calls with these tires.

*crossedge
Dapat naiinspect mo yung tires mo bro regularly. Pag may bukol na ganun alisin mo na kaagad. Hindi naman ba na gutter yan?

[timo07]

I don't think doing an engine break will save more fuel, your rpm will still not drop to minimum during engine break meaning you are still feeding the engine with fuel above the normal idling.

Being on gear when on a downhill road is a safety issue. You have better control of your vehicle. You're right that the breaks gets hotter when in neutral as it puts more strain on the breaks when there's no help from the engine.

Sir Dokleng sa VVTI-gas pwede rin bang ireset ang ECU para ma improve yung fuel consumption and how to reset, same din ba sa diesel? Thanks

for what purpose would an owner reset the ECU? under what circumstances? is there any beneficial effect on that?
thanks....

As he mentioned in his previous post, this should make the engine more efficient. Without understanding how the ECU works in an engine, you cannot really tell if it will have an impact or not. The ECU is like the processor in your home computer. In a vehicle, it has the critical function in fuel management.

Dokleng2001, I just don't understand why resetting the ECU every now and then will have this result. The O2 sensor in the exhaust should provide an up to date data on which the fuel/air mixture will depend on. I don't think it needs to view or refer to logged data to do this.

Sorry to the others, i think this discussion will be more appropriate to another thread that has a discussion specific to fuel system, etc.

I think you are right that this discussion is not appropriate here.

And, resetting your ECU again and again might shorten its lifespan, I think.
Kung malakas na sa gas, fuel pump na siguro may problem, not the ECU.

just got my innova e diesel last month and got my plates this week. They gave me the caltex 5000 frees gas and it will expire end of this month. sna they gave it in advance... i only have less than 2weeks left, my everyday usage of the innova is going to my son's school. Now i have to set long drives to use the free gas/diesel.

Schedule a vacation... sa malayong lugar. O kaya benta mo sa mga kakilala mo, samahan mo sila magpagas.
