oh ya.. forgot to include plug cable in my 1st stage modification.. hehe..
anyway, it's good to have an aftermarket plug cable.. but u also need an aftermarket distributor and/or coil to go with it as well
Air + Fuel + Spark = Power
More Air + More Fuel + More Spark = More Power
for an NA to increase 8 to 10 ps is no easy task. Then again i've heard that dynojet and dynodynamics yield a 20% difference , so in the event you 1st dyno in dynodynamics , then go dyno again in dynojet ( similar car ) doesnt mean u gain 20% power
Fair observation, and agreeable. Looking forward to your dyno, since numbers walk the talk.
Personally I won't invest so much in cables since over time they will corrode/oxidize.. and more interested in active spark amplifiers such as those that raise the voltage for spark plugs or something like okada projects.. not sure how those works.
Erm, I don't understand your lambda part. If lambda higher, AFR = higher rite?
If AFR high means you are running lean
When you lean out, you have more heat than usual
When you have more heat than usual, you ignite your fuel before it can spark hence knocking?
Then furthermore, if you rev high, the high heat = piston meltdown?
Surely if you use a car which the mixture is rich (most stock ecu) you may feel its a bit laggy, but its to increase the lifespan of the engine. But yours lean it out? Then the ECU eventually will compensate (of course up to a certain extent). Then that may explain why when Izso put back the stock cables it started to feel like dying because the engine i choking on too much fuel?
I still don't understand your Lambda part
I derived my explanation from here:
Air–fuel ratio - Wikipedia, the free encyclopedia
I do not mean to offend anyone but since this is a mythbuster, I am more interested in the real science to explain it rather than just hearsay. I am not an engineer or mechanic, but I am a science student, so I am keen on scientific proofs.
Item #1
Would it be safe to say that the ECU was NOT adapted to the stock cables thus the sputtering, slower revving and sluggishness?
a cable that measures the same, would perform the same. a cable that doesn't, well, doesn't perform similarly. being different doesn't necessarily means better.
also, its safe to assume there's a margin of error between dyno runs, maybe +/- 5%? I'm not sure as I don't own one, but its standard for any measurement device.
Item #2
You mentioned the creator approach OEMs, so is any car manufacturer using it? Just curious.
diff spark plug had diff char which need diff tuning, cannot really saying the cable was doing all the works but it's the setting also took a lot of measurement as well~
just my 2-cents~ cheerio~
I've got something in my mind. What does the ECU adapt to, when we have a bigger spark? The controllable parameter to the ECU is fuel. When less air going into the chamber, the ECU adjust accordingly to it. But when we have a bigger spark or misfire, as far as I understand, the ECU does nothing to counter it as it has not control over them other than providing signal to give electricity at the right time. Unless I am wrong. Any bro can clarify?
