I heard a lot about this Zaptor performance voltage stabilizer from AOCM, and have seen it installed in the Toyota Avanza of most AOCM members. It is a proven product which able to boost the performance of Toyota Avanza, and I have it installed today during the AOCM TT session. It comes with double sided tape and I sticked it on one of the leg of my Ultra Racing strut bar near the battery.
Today's car is functioned by many electrical and electronic components, the most important being the Engine Control Unit (ECU) which is a computer controlling the engine operations of the car. The ECU is highly dependent on all the sensors that provide accurate data and signals to coordinate various parts in different places of the car. This ECU can give the best judgement if and only if the signal received is accurate, which is affected by the electrical flow of the system. Therefore, a stable and powerful electrical system in the car will ensure best torque and response at all times.
The function of the voltage stabilizer is to stabilized the electrical current generated by the alternator, by storing some electrical energy in capacitors so that stable and constant electrical energy can be maintained all times even if there is voltage drop or surge across the car electrical system. It can also filter out electrical noise and eliminate irregular current flow in the car electrical system. Its working concept is similar to the Power Saver unit in my home.
Zaptor performance voltage stabilizer is developed by a member of Volvo Owners' Club of Malaysia (VOCM). The Acoustic Gold III version is waterproof, fuse protected, has voltage tolerance of up to 25 volts and operating temperature up to 105 degree Celcius. It has a compact size with a 7-colour battery status LED indicator. Most importantly, it functions in par with the branded voltage stabilizer made in Japan, and is distributed in AOCM at a much more affordable price. It is probably the lowest price voltage stabilizer product in Malaysia that can function effectively.
My feelings to the car after installation:
- engine starts immediately when ignited, there is no delay.
- engine respond faster and the fuel pedal is felt a little bit lighter. Probably this will improve in fuel economy.
- car accelerate smoother with increased torque as ECU works better.
- the RPM is very stable during idling, not so affected by air-cond condenser kick-in.
- cabin lights and headlights seems to be brighter.
- car audio sounds better.
I was told that the car battery water level will drop faster after the installation of this voltage stabilizer due to the charging effect. As such, using maintenance free battery is more convenient when voltage stabilizer is installed, to eliminate the need of frequent checking and top up of battery water.
