Modif mesin Taruna F Series

[Mikel]

halo semua, salam kenal

mau nanya nih, gw bawa Taruna F Series, masalahnya adalah mobil itu
cuma mau terima Super TT, waktu diganti ke premium (mau hemat) langsung ngelitik temen pernah nyaranin untuk puter negatif distributor, udah gw puter terus dipas pasin sampe gak ngelitik. Dan sekarang masalahnya, mesin jadi ngegerung dan tarikan kurang banget

waktu tanya temen gw, itu efek samping mesin yang pengapiannya kecil karena distributor dibikin negatif... pada akhirnya dia nyaranin supaya ganti koil dan kabel busi untuk gedein pengapian, dan kepada ujungnya
peningkatan tarikan

karena bingung ada yang pro dan kontra, pertanyaan gw adalah, apakah aman koil dan kabel busi diganti? apakah bisa mengatasi kurangnya tarikan di Taruna gw? apa efek buruknya?terimakasih atas masukkannya

p.s. gw sedikit buta tentang mesin, paling tahu cuma soal Honda (fan boy abis)

Penggantian Coil dan Busi membuat pengapian lebih sempurna sehingga pembakaran menjadi lebih baik .. mungkin lebih baik jika dibarengi dengan penggantian saringan udara dan saluran gas buang.

Kalo mo murah coba ganti merk VARSO silver buat busi en kabel businya SCAT .. tarikan bisa lebih responsif untuk rpm rendah

[Mikel]

ada efek samping gak?

penggantian busi semata bisa meningkatkan kinerja? wah hebat juga.... baru tahu

ada temen punya bengkel nawarin paket 2 juta untuk ngurus semua keluhan gw, itu kalo 2 juta diapain aja yah? katanya sih yang paling penting ganti koil dan kabel businya

[Equalizer]

penggantian seperti itu sih biasanya gak ada efek samping ya mas

coba deh lebih jelasnya buka Taruna Owner

Wah kalo ganti koil dan busi tampaknya gak begitu banyak ngaruhnya kalo ECUnya gak diremap lagi.
Baca aja di forum umum ttg busi.

buset dah, taruna cuma bisa diisi ama super TT ??? ;( emang kompresinya mesin taruna berapa sih?

makanya gw juga bingung... kalau gak salah ya, kompresi taruna 9.5, kata temen gw itu koil yang di taruna gw jelek (dari pabriknya, sampling error), ada juga yang bilang kompresinya tinggi supaya bisa memberikan tenaga kalo dipaduin dengan bensin oktan tinggi
temen gw bilang, mesin 1500 EFI taruna di brosurnya menghasilkan 88 pk, dan mesin kijang 1800 EFI (EFI atau gak lupa) menghasilkan 86 pk, tapi tarikan lebih enteng di kijang karena torsi maksimum udah didapet di puteran rendah. Pk yang dihasilkan taruna dibrosurnya dibilang menggunakan oktan tinggi jadi ketika kijang dikasih bensin oktan tinggi di brosurnya bisa ngelewatin taruna

bagaimana sih caranya remap ECU? bukannya itu cuma bisa diganti... maap kurang ilmu di otomotif nih

forum taruners udah jadi forum tertutup, males ngurus pendaftarannya

[Equalizer]

remap ECU itu sama aja kan sama reset ECU ?
Silahkan baca ini kalau memang reset .

ECU Reset
Definition

The ECU "learns" about your engine as you drive the car. The "learning" is actually a process that the ECU uses to track the tolerance changes of the sensors and actuators on the engine. Two examples of these values are the position of the idle-air bypass valve (automatic choke) at idle with the A/C on, and the trim gain on the injectors. The ECU stores these "learned" values in battery backed-up RAM so that it doesn't have to start from scratch the next time you turn your engine over.

"Resetting the ECU" is the process of clearing all the long term memory from the ECU's memory. These variables trim idle speed, fuel, spark, and more. The ECU will also store trouble codes for diagnostic capability. By resetting the ECU, the trim values will be set to some neutral default value and all of the trouble codes will be cleared.
How-To

To "reset" the ECU, all you have to do is remove the source of backup power. To keep the memory alive while the car is off, the ECU has a direct line, through a fuse, that goes right to the battery. This is usually the same line and fuse that supplies backup power to your radio so it doesn't forget all of its settings. In a DSM, this is the fuse that controls the footlights that go on when you open your car door. On a 1990-1994 DSM, this is the 10A fuse in the lower-right-hand-corner of the fuse box near the driver's footwell. On a 1995+ DSM, this is the 10A fuse on the right-hand side of the middle row of the same fuse box. Pull this fuse with the key out and wait for about 15 seconds, then put the fuse back in. Your ECU has now lost all of its long term memory values and will "reset" them all to defaults when it next powers on. By the way, the factory radio's memory lasts for a minute or two, so you probably will not lose your saved stations.

Sometimes people like to pull this fuse when they are working on or cleaning the interior of their car. This fuse also controls the lights that go on when you open the door, so many pull this fuse so they don't drain the battery during their job. However, this will also cut backup power to the ECU.
Myth

There is quite a bit of mythology revolving around resetting the ECU. Many people mistakenly believe that they need to reset the ECU after installing major engine modifications. Others believe resetting will resolve engine problems. Neither are correct.
Reality

The ECU is always tracking the engine's sensors and actuators. Resetting the ECU does not cause the ECU to learn engine changes any faster. The ECU is always tracking the gradual changes in the engine sensors and actuators. The ECU never gets satisfied with a setting, and is always updating the trim values. It will discover whatever change you made to your engine and make the appropriate changes. In fact, unplugging the ECU will most likely increase the learning curve of the new part.

On a DSM, there are only two reasons why you would want to reset your ECU. One is to clear a CHECK ENGINE light or error code after fixing the problem that caused the error. The other is to reset the spark advance trim value. The advance trim controls how much the timing is retarded from what the factory engineers considered optimum. This particular trim value is the only one the ECU "resets" to a non-neutral MAX value. If you are driving on low grade gas, the pinging picked up by the knock sensor causes this trim value to be lowered, and your timing to be retarded. If you go to the track and put good gas in the tank, you might not want to wait for the ECU to learn about the new gas and advance the timing. So resetting the ECU in this case makes sense. However, in the process, you will lose your idle and fuel trims (probably not too important for drag racing, though).
Questions

Won't clearing the trouble codes make the car run better? On a DSM, no. If the ECU notices a problem with a sensor, it will flag a code and possibly turn on the CHECK ENGINE light. Should the problem go away, the ECU will turn off the light and start using the sensor as normal once again. The code will be stored inside for later diagnostic retrieval. But that code being stored does not affect the ECU operation in any way.

I reset the ECU, and now the car runs rough! Why? The engine may run rough or idle poorly right after ECU reset. The ECU now has default numbers in its trim memory - it has to adjust them to match the tune of your engine and its sensors and actuators. It might take a day or two of driving in traffic before the engine will settle down again. Now you know why the ECU remembers these values in the first place!

coba deh ganti packing silinder head lebih tebal biar kompresinya turun dikit, dan ajust distributornya .... kayaknya memang disetting untuk TT ( kompresi tinggi )
