Mythbuster/Does-it-work? Spark plug cables

[Veloc]

IMHO, ECU control fuel & spark timing

It detects air by AFM, MAP, etc & inject fuel according to the programmed air fuel ratio

And it checks with knock sensor & oxygen sensor

Then it adjust the fuel & spark timing accordingly

VTEC, VVT, etc has another set of programming n sensors

This is from my knowledge la. I could be wrong

ECU didn't detect a bigger spark. It just detect knock & oxygen

If it detect knock, it will inject more fuel & retard spark timing

If it detect less oxygen, it will inject lesser fuel & advance spark timing

In the case of bigger spark, the oxygen has been burn completely..

So, ECU will reduce the fuel & u'll get better FC

I stand corrected

Agree with this. Besides burning more completely and the ECU injecting less fuel, the increase response and torque will also result in less throttle input giving better FC.

Anymore reviews? Any update on the dyno chart?
Anybody else using this Best I Cable?

How much is a set (4 cables)?

I agree that spark timing is to avoid knocks..I get the theory of bigger spark results in better combustion i.e. a more complete burning. But I personally do not think that it affect or being effected by AF ratio. Of course, with bigger spark, better combustion, thus more power and smoother ride. I think it actually improve the burning efficiency instead of providing more fuel/air.

I believe that a good ignition cable can improve the car responsiveness and "smoothness" we called...berapa RM sebiji btw?

You believed yourself that a stronger spark leads to more complete burning. Complete burning on the other hand means AFR is affected. So ECU read sensor readings, and adjusts according to the tune and adjust its output potentially leading to better performance.

I sense a bulk buy coming soon...
