My car idle speed value is low from standard figure in the specifications which is 650 +/- 50 rpm for manual transmission model. Noted for automatic transmission model 700 +/- 50 rpm.
I decided to DIY cleaning engine throttle body. Let's get on to the DIY shall we?
Tools needed are:
- Phillips screwdriver
- Flat head screwdriver
- 10 mm socket wrench
- 12 mm socket wrench
- 12 mm open wrench 2x
- Torque wrench
- Contact cleaner (cotton buds, dry cloth)
- Lubricating oil (WD-40, Vaseline)
- Engine degreaser (painter brush, copper brush, etc.)
Level of difficulty: Easy
Estimated time completed: Varied (at least an hour or more)
These are the tools needed.
First remove by pulling out the air cleaner inlet duct (red circle) and move it aside. Release the two springs of the air cleaner housing (yellow circle) then lift off the upper section and remove the filter element.
Lift the canister purge valve off its holder, and move it aside.
Disconnect the airflow meter wiring plug.
Loosen the accelerator cable adjuster nuts and remove the cable from the bracket.
Remove the three mounting bolts using 10 mm socket wrench and lift off the air cleaner housing.
Remove two screws using Phillips screwdriver and pull out the airflow meter.
Use contact cleaner, spray the intake air temperature sensor gently wipe with cotton bud or dry cloth. Tip airflow meter upside down and have a look inside you will see two thin wires with small resistors. These get hot and get coked with oil. Clean them with contact cleaner. Refit in the reverse order of removal.
The intake air temperature sensor cleaned (yellow circle).
Disconnect two wiring plugs (blue circle), remove four housings (red circle), remove two bolts (yellow circle) with 12 mm socket wrench (15 lbf.ft), one bolt (orange circle) with 10 mm socket wrench (6 lbf.ft). Lift the engine throttle body.
Clean and wipe the carbon deposits inside the intake manifold exhaust with dry cloth.
Retain the O-Ring and you need to lubricate it with Vaseline when fitting back into place.
Cleaning in progress with engine degreaser.
Once cleaning the engine throttle body done, refitting is a reversal of removal. Check-up everything are tighten up. Start your engine and check-up for abnormalities.
First minute idle speed after engine started.
Five minutes idle speed after engine started.

|Seat Belt Convincer|
Tomorrow 9th June 2012, BSJV promoting ROAD SAFETY DAY 2012 - Saving Lives on Brunei's Roads at Pusat Insani Seria & OGDC from 10:00 am to 4:30 pm. Come by stop at our Schlumberger booth to try out our "Seat Belt Convincer". They will be a lots of fun and activities throughout the day with goodies and prizes to be won.
What is Seat Belt Convincer?
The Seat Belt Convincer is an easy to use educational tool that allows riders to experience forces of a low speed crash to reinforce the benefits of wearing seat belts whenever a vehicle is in motion.
The Convincer is developed to educate the general public of how beneficial the use of seat belts can be even when involved in a low speed collision. It is a very effective tool for safety presentations at community events, drivers education programs, students, or any event where the entertainment and safety education factors associated with the Convincer would be of benefit. It allows the rider to experience the surprising amount of force generated with such low speed collision and to gain respect for the benefit that a seat belt can provide.
The passenger enters the carriage at the top of the slide and buckles into the seat. Once the rider is properly fastened in the seat belt and its fitment is double checked, the operator rotates the lever from the "return" position to the "convince" position. The secured rider slides down the track and collides with the front bumpers, safely experiencing a simulated crash. After impact, the rider exits the machine at the bottom. The Convincer is then returned to the top of the carriage in preparation for the next rider.

|Cold Air Intake Bypass Valve Filter|
Cold air intake bypass valve filter helps your engine intake to have consistent air flow and prevent hydraulic-lock. Many cases driving under heavy rain or wet floor, aftermarket cold air intake will often absorb the moist into the filter, having it unable to have air flow.
The bypass helps resolve that problem, by having a second air filters. This secondary filter will prevent water from going into the intake causing damage to the engine.

Chassis Dynamometer Differences & Testing Goals:
Much debate revolves around measuring the power and torque levels of your vehicle and engine on a chassis dynamometer (dyno). One machine may give your measurements drastically higher than the next. My first objective is to explain some important differences amongst the most widely used dynos. However, my main objective is to discuss the importance of setting dyno testing goals.
Inertia vs Eddy Current Dynos
There are a variety of different types of chassis dynos; however, the two most common machines are either based on inertia or eddy current magnetic retarders.
Inertia dynos calculate power by measuring the power required to accelerate a drive roller. The drive roller has a known mass. There is no load that is moved, in turn there is no measurement of load. The most common inertia dynos in use are manufactured by DynoJet and Mustang Dyno.
Eddy current dynamometers have an electrically conductive core, shaft, or disc. It moves a across a magnetic field to measure resistance to movement. The eddy current magnetic absorber allows for quick load change rates. The best models enable the operator to conduct true steady-state and controlled rate operation. The most common eddy current dynos in use are manufactured by DynoDynamics and DynaPack.
Roller vs Hub Style Dynos
There are also two main types of design used in chassis dynos.
Most dynos consists of rollers mounted in a frame or in a pit in the floor. The vehicle is strapped to the frame or floor and driven on the rollers. The most popular manufacturers of roller style dynos are: DynoJet, Mustang Dyno, and DynoDynamics.
Another type of chassis dyno is one that is mounted to the hubs of the vehicle after the wheels have been removed. A popular brand is DynaPack.
It is obvious that a roller type dyno will deliver lower measurements of power and torque, since the drive train loss is carried further. This loss is increased the further we move from the engine's flywheel, to the transmission, to the axles, to the wheels, and finally to the tires. A dyno that measures at the hubs does not suffer from drive train losses at the wheels and tires. Therefore, it will measure higher power and torque numbers that are closer to those measured at the flywheel.
Correction Factors and Smoothing Factors
Dynamometer manufacturers also incorporate different features with regard to atmospheric correction and smoothing. DynoJet uses a smoothing factor to average out the bumps and spikes to compensate for the fact that the raw data from the DynoJet's acceleration sensors is very jagged and noisy. The scale runs from 0, least smoothing, to 5, which eliminates nearly all spikes and dips. You can imagine that the spikes and dips can significantly distort the mesured power and torque numbers. Atmospheric corrections are handled by incorporating dyno room temperature, humidity, and barometric pressure in to the dyno's software. With these variables, the dyno operator ensures that the measurements are equivalent during widely varying seasonal conditions.
All types of chassis dynos share one common characteristic: they are tools to measure output levels and to prepare appropriate tunes for the intended purpose of the vehicle. Therefore, it is of lesser importance what type of kind of chassis dyno is used, than what the dyno professional does with the machine.
A good tuner will prepare your street vehicle with a consistent combination of air/fuel, ignition timing, and cam timing. The tuner's focus will be on safety and reliability, not power numbers. On the other hand, a good tuner will prepare a track oriented vehicle for the highest power and torque results that are necessary for the type of racing intended. A much more aggressive tune is justified in race vehicles, with a greater focus on power numbers. Regardless of what the intended purpose is of the vehicle, the tune should reflect a repeatable, lasting combination of air/fuel, ignition timing, and cam timing.
In conclusion, considering the large amount of differences from one dyno to another, it may seem difficult to determine the best approach when you want to put your vehicle on a chassis dyno. However, your decision will most likely depend on the proximity of the dyno shop, their rates, their customer service, and their availability.
Here are some useful tips for successive dyno testing sessions:
- Use the same dyno for all your testing
- Ask the dyno operator to use the same smoothing factor (DynoJet)
- Ask the dyno operator to use the same correction factor or method (all)
- Establish a baseline first, which can be a stock vehicle, a stock engine, or just the start of a new project on your already modified engine
- Compare your baseline results to the results of the next trip to the dyno and every subsequent one
- Ask the dyno operator to attempt to conduct successive dyno pulls within the same range of engine and intake temperatures
- Be consistent with gear selection, dyno pulls in different gears will produce different power and torque measurements
- Always check with the dyno operator how to properly prepare your vehicle for your visit

|Universal Adjustable Fuel Pressure Regulator|
Some say more fuel + more air = more power after tuning.
The answer is NO.
Fuel pressure regulator is to maintain fuel line pressure but not to increase fuel. Bigger injector (cc) + fuel pressure regulator + fuel pump = more power and by changing only one part is no use at all.
With a proper tuning on a dyno for optimum level, owner can get at least 8 WHP increased on normal aspiration by doing proper tuning to fuel pressure regulator for better air fuel ratio.
Fuel pressure regulator doesn't increase horse power actually unless fine tuning the injector timing to maintain A/F ratio. The benefit of higher fuel pressure regulator, apart from ensuring the engine will not run lean is possibly finer fuel spray which aid mixing, evaporation, and enhance combustion. But this is provided the injector holes is small enough so it will spray very fine droplets, else its useless. AFAIK, only those with multiple holes benefit from this.
Be careful when tuning fuel regulator with stock injector as they will defect more quicker. Try to study or Google regarding fuel pressure is suitable for turbo, supercharge, or normal aspiration. Learn without guidance sure will make you astray, so basically learning using Google doesn't prove that you good enough too.
Logically figure influenced a number of reasons:
1. Power to weight ratio (weight of car engine).
2. Type of tires used.
3. Every car has a different gear ratio.
4. Weight mass of the roller may vary between each roller dyno machine.
5. Different units of measurement used, HP, BHP, WHP, PS, etc.
Usually do a dyno before and after mods. Do a comparison with a friend with a same mods and finally do a side by side test on the road against factory stock and your question may be answered.
