I'm interested with the bitumen spray. Got anyone to help to apply? Need to dismantle the wheel well?

QUOTE(davidke20 @ Sep 6 2012, 10:58 AM) down hill On new EFI engine, fuel supply is cut on downhill. It doesn't burn lean, there's just simply nothing to burn. The combustion chamber temperature should not rise excessively just because of downhill high vacuum reading.Wheels is spinning faster than engine, you will get all sort of error in reading vacuum. Most of the time during down hill, your vacuum reading stay below 23(24,25). When vacuum reading stay below 26, also mean the combustian chamber burning lean. Lean burning can raise temparature up to 800'c. Despite your sensor reading as normal 400'c at the catcon, you wouldn't know what kind of harm done to your head gasket. Often I heard people going Genting come back with a wreck engine despite radiator didn't boil, there's a good chance that the head gasket was burnt during downhill due to ultra heat developed by lean burning. Manual transmission can opt of lower speed downhill. Or declutched at idling RPM. Auto/CVT, I have no experience, you'll have to figure it out. For carburettor engine, the lean burn may occur. Disengaging the gear on EFI engine will cause fuel to be injected again during downhill, wasting some fuel. From Toyota: http://forum.diyefi.org/download/file.php?...a086b&mode=view |

QUOTE(lhwj @ Sep 6 2012, 02:02 PM) Actually IINM the owner's manual doesn't recommend that we try push starting the Gaga Even when fuel is cut, the fuel pump continues to function to maintain pressure. So the fuel flow rate never goes to 0, even when NGV is used.I live on a hill here and there's quite a long stretch downhill whenever I leave my house. I just coast downhill in 4th gear at about 50 km/h. If I step on the throttle while coasting I can notice the engine kick back to life, so that's why I believe our Gaga has the fuel cut off while coasting in gear Anyway Datuk Dares can try out with his new OBBBBBDDDD IIIIIIIII reader and see if the fuel flow rate goes to 0 whenever he coasts downhill, cos CVT got engine breaking rite. That should put the matter to rest. Added on September 6, 2012, 2:05 pm Hantu mana ada berat And fuel flow rate is not a good way to judge fuel consumption. On my NGV ECU follower, there is a reading from original ECU called T.Inj/RPM. Petrol injection time per RPM, this will tell how much fuel the engine is using.

QUOTE(redshark_999 @ Sep 6 2012, 07:41 PM) omg! jz checked tire pressure jz now, 45 45 for front and 34 34 for back and have been running at least 1000km on it -.-" Overinflation is at least better than underinflation. Overinflation doesn't eat up the thread faster, just uneven. Speaking about driving risk, underinflation is dangerous.this is gonna burn the thread faster rite? thx god no tire burst or whatsoever-.- Btw, tyre pressure is to be measured when tyre is cool. i.e. Measure on the morning after you stopped the car for the entire night. A driven car will raise the tyre pressure significantly when measured. This post has been edited by mengsuan: Sep 6 2012, 08:12 PM |

QUOTE(davidke20 @ Sep 7 2012, 09:11 AM) 2) Its weird more fuel goes in will reduce engine brake(keep the engine alive) to really cut off fuel supply, turn your key back to ACC position from ON(so you don't lock your steering). Now that is real engine braking Don't wanna argue with those with OBD2, but engine shall not cut off fuel supply until shut down. If the cut off fuel supply did exist as TOYOTA suggested, then the problem will be when rolling downhill, if you step on clutch then engine mati straight away. No powah steering, no hydraulic brake, no ABS i'd think when injector/ml 0 reading meaning not sending signal to the injector, but fuel being tarik by vacuum to keep the engine alive. The injector response time is quick enough to start again when the RPM goes a specified ECU threshold. You can also see someone mentioned: "DFCO was a requirement for all OBD II vehicles. So anything post 1996 should have it." http://forums.nasioc.com/forums/showthread.php?t=2184765 I haven't found Persona's parameter for injection duty cycle from OBD2, but at least I can see the engine entering open loop mode during the fuel cut, suggesting that the ECU does not monitor AFR anymore while rolling down the hill. |

QUOTE(dares @ Sep 7 2012, 11:50 AM) Since getting the OBD scanner, I notice my car goes into open loop in 2 situations - cold start and deceleration (engine braking) O2 sensors gives lambda value, which the ECU uses it to monitor AFR. Open loop does not conclude fuel cut, but for fuel cut to be allowed, the ECU needs to enter open loop.Open loop doesn't mean the ECU is not monitoring AFR, it only means it is ignoring the O2 sensors. It will continue to inject fuel based on the MAF sensor input. That's why during cold start it goes into open loop so that more fuel is injected to warm up the engine. Same goes for WOT driving to ensure the engine does no run lean. I assume the same is happening when engine braking, because the ECU needs to inject more fuel to prevent the engine running lean, hence it has to ignore the O2 sensors aka invoking open loop mode. P/S: OR it could mean it is ignoring the O2 sensors so that it can cut off fuel But all in all going into open loop is not enough to conclude that it has in fact cut of fuel supply. |

I know how much is bolt on. Turbo and supercharger also survey already. Minimally 4-6k without ECU management, 8-12k with ECU management. |

QUOTE(davidke20 @ Sep 9 2012, 08:01 PM) Bro, have anyone ask you before, why not just swap a Mits engine? Over the long haul of no turning back modding life, getting a better platform such as 4G63 will be cheaper than bolt on and or stick to S4PH No? I try to stick with Campro, actually I like it. Moreover 4G63 requires mounting change I think.Sos More sos |

Mine appears to stay connected and remain visible via Bluetooth even after days shutting down the car. But no issue, the power used is very little.

I've notice quite some times while tackling rubber hump at basement parking.. drive very2 slow (avoiding sagat style). Aircond switch on.. Manual Transmission FLX.

I have also encountered the max RPM situation. It's a sign showing drivetrain fault, nothing in specific.

That engine bay wash is a bit WTF. Water and soap all over the battery and fuse box.
