Tayar Michelin ni - cepat haus dan botak.



Tayar Michelin 100/80 dengan Rim saiz 2.50 sesuai dan padan tetapi mahal betul. Membazir. Taubat nak beli lagi sebab cepat haus. Corner stabil walaupun hujan dan basah. Tetapi ramai orang kata tayar ni tak stabil dan licin semasa di corner, lebih lagi waktu jalan yang basah dan hujan.

 1. Original tayar kira-kira 6000km sahaja. Bunga ada banyak lagi. Tapi dah tak guna. Macam licin walaupun jalan tegak sahaja. Top speed semasa turun bukit, badan tegak dan relaks 135km/h. 15/39 sproket. Di highway ada salah satu tempat bila lalu dengan kelajuan 120km/h tayar motor belakang macam beralun-alun, jadi kena pegang handle baik-baik. Lagi parah bila langgar garisan putih pada kelajuan tersebut. Motor anda macam ada raksasa buat main handle anda.

2. Tayar ni haus dan botak kira-kira 5000km sahaja. Di highway ada salah satu tempat bila lalu dengan kelajuan 120km/h tayar motor belakang macam beralun-alun, jadi kena pegang handle baik-baik.
Lagi parah bila langgar garisan putih pada kelajuan tersebut. Motor anda macam ada raksasa buat main handle anda.

3. Tayar 110/80. Macam jenama VIVA. Baru je guna. Puas hati dengan harga sebab murah RM115. Adalah dalam 2000km baru guna. Stabil dalam macam-macam keadaan. Langgar lubang pun relak tak ada goyang-goyang. Overtake semua jenis kenderaan dengan yakin. 120km/h lalu garisan putih tiada masalah goyang-goyang. Acceleration biasa sahaja. Tiada rasa macam berat atau beban. Naik bukit tak ada masalah. Okay je. Cuma 100km/h ke 120km/h susah sedikit. 120km/h tu kira beruntung disebabkan tiada angin rintang.

Boleh Pula Hilang Benda Ni..

"Made in Japan" tu, haha. Original Yamaha untuk  FZ150i banyak dan murah "Made in Indonesia", tetapi bila bawa masuk Malaysia melambung tinggi harganya. Contoh Fuel Pump beli di sana ~RM218.00 sahaja. Harga HLYM ~RM610.

Yang lama hilang akibat lupa nak ketatkan skrew selepas tukar sproket belakang. Banyak juga guna petrol habis akibat nak cari skrew brake belakang ni. Aku cari banyak kat kedai hardware. Semuanya hampir-hampir boleh masuk tapi tak habis benang skrew. Akhirnya aku beli juga walaupun boleh masuk sedikit. Janji boleh guna. Boleh tak terfikir nak cari benda tu kat kedai motor. Sudah lama tu tanya kat kedai motor, kedai tu tak ada jual yang original YAMAHA tapi boleh masuk dan ketatkan sebab sama saiz dengan YAMAHA 125z punya.

Akhir sekali, beli yang asli baru puas hati. Alhamdulillah.

==========================================
Highest rpm, lowest map reading.

However, sequential injection does not necessarily mean you are injecting into an open intake valve all the time. The intake valve is only open less than 30% of the time in a typical 4 stroke engine.

Once you are trying to produce more than about 25% of maximum HP your injectors are firing for longer than the intake valves are open. If your maximum HP is correctly calibrated to a safe 80% duty cycle, your injectors are injecting well over 50% of the time on closed valves.

At higher rpms, it becomes increasingly difficult to inject while the valve is open. For example, if your Req_Fuel = 15.0 ms, and your maximum duty cycle is 85% then the interval between injections cannot be closer than 17.6 ms.

Buat code yang senang-senang dahulu, janji boleh start enjin. Tune tu nanti dulu. Perhubungan data input antara RPM vs TPS vs COLS langkahnya hampir serupa dengan langkah masa buat projek temperature monitoring system kerana projek tu menggunakan 4 input tapi tiada guna interrupt.

Masalah:

PWM output tak dapat nak program. Kena belajar lagi.

MAP vs RPM vs TPS vs Air Temp

MAP controls the acceleration enrichment table (AET). AET is an additional fuel used to improve throttle response, just like acceleration pump on a carburator.

Load Sensing.. nak guna TPS atau MAP ?

volt/psi relationship for the stock map sensor...

Map-based accel enrichment.

TPS-based is likely easier when use single butterfly.

* Cold start pulse widths and acceleration enrichments.

MAP Sensor.

 MAP Sensor Definition:

Absolute pressure is usually 1 atmosphere (1 atm) or 14.7 psi.

Refers to a manifold absolute pressure sensor, a variable resistor used to monitor the difference in pressure between the intake manifold at outside atmosphere.

This information is used by the engine computer to monitor engine load (vacuum drops when the engine is under load or at wide open throttle). When the engine is under load, the computer may alter spark timing and the fuel mixture to improve performance and emissions.
