Poor man's Rolls-Royce

                                  A Journey of Enhancements

                                 My Honda Jazz VMT

When I first laid my hands on my Honda Jazz, I was thrilled at the prospect of owning a reliable and efficient vehicle. However, the initial joy was dampened by a sense of lethargy in its performance. Determined to unlock its true potential, I embarked on a journey of upgrades and fine-tuning, transforming my driving experience entirely.

The first step in my quest for improvement was upgrading the engine oil. Swapping out the stock oil for 0W-20 Idimitstu oil proved to be a significant turning point. Not only did it enhance the engine's efficiency, but it also laid the groundwork for further enhancements. Throttle body and injectors cleaners were employed to do its duty.

Next, I decided to address the ignition system by upgrading to Double-tipped Iridium plugs. This upgrade aimed to optimize the combustion process and improve overall performance. However, despite the improvements, I still felt a lack of low-end torque, especially during acceleration.

Undeterred, I embarked on a 3600 km journey to Madhya Pradesh and back, during which I experimented with adding 2T oil to the fuel. Surprisingly, this seemingly unconventional addition resulted in a noticeable improvement in drivability. It was as if my car had finally begun to awaken from its slumber.

Despite the improvement, the quest for better performance continued. Upon returning, I sought the expertise of Harish, a trusted friend and expert Cars, to further fine-tune my Honda Jazz. One adjustment that made a world of difference was reducing the spark gap to 0.9mm, a departure from the 1.1mm recommended by Honda.

The optimal spark plug gap may vary depending on the type and condition of the engine, the type and material of the spark plug, and the environmental factors, such as temperature, pressure, and humidity.

Iridium plug's spark gap is less compared to their copper counterparts. While the exact difference depends on the specific spark plug models and engine.

The impact was immediate and profound. The reduced spark gap facilitated earlier ignition after the compression stroke, resulting in a significant boost in low-end torque. The transformation was nothing short of remarkable.

OEM HU was upgraded to Android based HU with twin cameras, head lights were upgraded to OSRAM Night breaker. Wipers were upgraded to frame less Bosch wipers.

In addition to addressing the mechanical aspects, I also took the opportunity to attend to some minor issues within the cabin. Securing loose wires in the dashboard with tape eliminated any rattling noises, further enhancing the overall driving experience and one who did all these is Harish Naik , I am grateful to him.

My journey with my Honda Jazz has been one of continuous improvement and discovery. Through a series of upgrades and adjustments unlocked its true potential, turning it into a dynamic and responsive driving machine. With each enhancement, my connection to the car deepens, reaffirming my belief in the power of customization and fine-tuning to elevate the driving experience.

Update June 2024 : My Jazz V MT had an unusual problem where it hesitated during acceleration from a standstill and even when shifting gears. Occasionally, the engine would stall, even on flat surfaces. I spoke to the Honda service guy about it, but he couldn't provide any convincing answers. Today, I took my car to Pridecars, where Harish attended to it. He cleaned the throttle body and MAF sensor.

During the test drive, the Jazz had no hesitation going up slight inclines without any acceleration, and I no longer had to worry about the car stalling.

Update: Today I checked the tyre air pressure and drove towards my factory.

Got wonderful results, car never had any hesitation or stalling symptoms.

Due to which I could drive the car with light foot on accelerator, drove with speeds between 20 to 60 kmph.

Car felt relaxed to drive and FE was hovering around 18 and finally 17.5 kmph for for city drive.

Please refer to my above blog on what other changes to be done, oil and spark plug, airfilter, tyre pressure, MAF and Throttle body cleaning are very important to get good FE.

Happy motoring.
