  1. Hi Don, Thanks for the useful information. Do you think any differences of ECU programming of an engine for a JDM and same engine mated to export directly to SL from Japan?

    Honda FIT GP1 - Engine Oil Burning

    Hey Hondaclub, I contacted the guy!!!! to me what he was saying was pretty strange. I just acted like a layman to get to know the guy. His first suggestion is to swap the engine with an Insight one costing Rs. 95,000. He did say that there is not such a problem with insight and he gonna swap the engine with little modification. But, we all know the truth of insights too. Then I asked for the piston replacement kit thing, his reply was it would be costly and not worth of the money spent on.... What I realized is this guy going after quick money with easy work!!!!! That's not professionalism!!!!!! Better stay away from him

    Delay of shipping

    Even I doubt whether It has travelled through SL!!

    Delay of shipping

    Following live tracking app says that it is in Durban right now :). I agree with iRage, often dealers are lying. In my case also, when I received vehicle documents, I got to know that the vehicle was shipped in another ship than what i was told. Don't rely much on the vehicle dealers, http://alltrack.org/9604914-636015657-vessel-gracious-ace-tracking
  5. You have a good point here. Probably, companies need to cut down the base value of vehicles by limiting safety options. Further, partly I do agree with the notion that this auto-breaking system is not suitable for our country, especially the pedestrian collision avoidance system. I narrowly missed few rear-collections due to morans who walk on the road and tailgating. I always, switch off the system when driving except on the highway. These systems are fine-tuned for the other part of the world having a proper road network and well-disciplined drivers and pedestrians. Though we can switch off these systems, always reactivated with next start I imported mine personally due to long waiting time at the Agent. However, best to import via the Agent since the warranty they provide. We never know complicated electronics in today's vehicles would fail......
  6. Yeah....You may not go wrong with EC. I have been using it for some time, but nothing to complain. Just a fun share below:
  7. But, MPI system adds a cleaning effect for valves avoiding carbon/sludge build up on intake valves. Of course in Pure GDI the chances of building up of carbon on intake valves are higher, if not properly tuned. Note this is a conference abstract: "A Study of GDI+MPI Engine Operation Strategy Focusing on Fuel Economy and Full Load Performance using DOE,DOI: 10.7467/KSAE.2014.22.3.042. The gasoline direct injection (GDI) system is considerably spreading in automotive market due to its advantages. Nevertheless, since GDI system emit higher particle matter (PM) due to its combustion characteristics, it is difficult to meet strengthened emission regulation in near future. For this reason, a combined GDI with MPI system, so-called, dual injection (DUI) system is being investigated as a supplemental measure for the GDI system. This paper focused on power and fuel consumption effect by injection mode strategy of DUI system in part load and idle engine operating condition. In this study, port fuel injectors are installed on 2.4 liters GDI production engine in order to realize DUI system. And, at each injection mode, DOE (design of experiment) method is used to optimize engine control parameters such as dual injection ratio, start of injection timing, end of injection timing, CAM position and so on. As a consequence, DUI mode shows slightly better or equivalent fuel efficiency compared to conventional GDI engine on 9 points fuel economy mode as well as MPI mode shows less fuel consumption than GDI mode during idle operation. Furthermore, DUI system shows improvement potential of maximum 2.0% fuel consumption and 1.1% performance compared to GDI system in WOT operating condition. Another One: The dual-port fuel injection system for fuel economy improvement in an automotive spark-ignition gasoline engine "https://doi.org/10.1016/j.applthermaleng.2018.04.027" Abstract The purpose of the present study was to investigate the performance of the dual-port injection (DPI) system in an automotive spark-ignition engine. The DPI system utilizes two port fuel injection (PFI) injectors per cylinder, i.e., one injector at each intake port. An original 4-cylinder PFI engine head was modified to accommodate total 8 PFI injectors. In the present study, three spray angles and two install configurations were investigated in the intake port visualization, steady-state part-load experiments, and cold-start experiment. The intake port spray visualization experiment showed that the wider fuel spray provided better fuel distribution, but also more wall wetting. The steady-state engine experiment at the several critical part-load conditions showed that the DPI system in combination with the open-valve-injection strategy achieved the most brake specific fuel consumption (BSFC) reduction of 4.6%. The average BSFC reduction of the 9-point experiment was 2.8%. The cold-start experiment also showed a fuel economy gain by the DPI system. In the cold-start experiment the wider spray angle exhibited higher total hydrocarbon emission likely due to the greater wall wetting observed in the intake port spray images.
  8. Mitsubishi 4B40 employs Direct + Multipoint injection system. Any difference between Multipoint and Port Injection?
  9. Guys, As far as the Direct (GDI) and Port injection (MPI) engines are considered, it is often said that the port injection engines are better in terms of the durability, ex- less bulding up of sludge on intake/exhaust valves, low cost of replacements. Problems related to GDI could become severe when mated with a turbo unit (in case of oil leaks etc). Due to combined benefits, many manufacturers nowadays are going for GDI and MPI combined engines....e.g. Mitsubishi Eclipse Cross 4B40 engine!!!!. However, it seems the C-HR (8NR-FTS) still uses a GDI engine. Why Toyota still relying on GDI? and is that indicate potential problems in C-HR in the future......

    Tools for DIY of Vehicles

    Guys, are following items needed for a break/caliper related DIY is available in Sri Lanka, if where I can buy them: 1. Silicone paste (Si Based lubricant) for lubricating guide pins. I know our mechanics use grease called "Rubber Grease - Seiken", is it a sort of Si based product? 2. Copper-based anti-sieze lubricant ( for break pad guiding sleeves and shims) 3. Thread locker

    Many thanks for sharing your experiences....

    Toyota vitz/ Suzuki Swift/ Audi A1

    Many thanks. Why an A1 is such difficult to maintain!!!! It seems like swift is the option., though we don't like. Bigger car is not an option, since this for my better half. The time it has come to get rid of the GP1 we have been using but Vitz is not near to it in terms of quality of the interior. It's really a pity that with the present situation in the market, we are left with very few options.

    Toyota vitz/ Suzuki Swift/ Audi A1

    Guys, After a few weeks of hunting for a small car, the personal preference is boiled down to an Audi A1. My only worrying side is maintenance. This will be tough daily runner 160 km up/down (col-kandy) at least 4 times a week. I am thankful if you could share the following information based on experiences since this gonna be our first Euro: 1. Maintainance - I am in Kandy. I don't know any garage handling Audis in here. Let's say, for regular maintenance, do we need to take it for a specialist garage (such as Vishwa) in Colombo?. I usually do oil change regular service by myself. Is it difficult for a Euro such as A1? 2. Availability of spare parts: We won't be able to wait for weeks if something goes wrong with the car. How about the availability of spares for A1 in Sri Lanka. 3. What are the main challenges in maintaining the vehicle compared to a swift RS (though we don't like it) 4. Fuel - The car which we looking for has been imported from Aussie. Would 92 petrol be okay for the vehicle? 5. The model has been around for a while in Sri Lanka. Any known faults recorded? or experiences are highly appreciated. Thanks

    Honda FIT GP1 - Engine Oil Burning

    Hi All, 60000 km after doing the piston ring cleaning option, my vehicle started giving the problem again. I am in a great trouble as I am not around in SL but the repair needs to be done urgently. In my absence, it will too risky to get it done at a garage. Thinking of going for the safest option, Contacted StXXXX MoXXXXs and their estimate is roughly around Rs. 250,000.00. To my surprise, they do not give any warranty for the repair except the verbal warranty that the problem will not come again. Guys, how trustworthy SM guys are to hand over the vehicle and get done the repair in my absence? given a warranty is not offered!!!! By the way, the vehicle has got into limp mode on the way to Colombo, as a temporary fix all spark plugs were changed and oil replaced with 40 (These stupid things can happen when a knowledgeable person is not around :)). The car has already done 153000 km, will the use of 40 thickness oil further degrade the engine? Now the vehicle runs okay but quite sluggish on hilly roads (kadugannawa). How risky to use the vehicle for a few weeks till I return back.......
