My manual says 91 RON minimum by the way.
'normal' is 91 RON...
There you go, replace 93 in my posts with 91...
Since that is the case, I can say with almost 100% certainty that you will LOSE power goingt from 91-98 and only advancing 2 degrees.
lose 'peak power' or 'power everywhere'?
you need to be specific, as i will be dyno testing this in the close future...
You won't be able to get conclusive evidence from a dyno.
The two sets of results will be closer than the mean tolerance in a dyno run so any results you get will be void....
Where you gain/lose power will depend exactally on how the timing map is setup standard. If at one point the map is more advanced than MBTT (incredibly unlikely but i'll humour you) then you will see a HIGHER power. But for the rest part, you will see a lower power level everywhere.
um, so what you are saying is that your theory that increasing timing will lose power, cant actually be proven or disproven?
well, this will be an interesting dyno session!
starting at 14' i will do 3 runs,
let it cool 10 mins
moving to 16' i will do 3 runs
let it cool 10 mins
move to 18' i will do 3 runs
let it cool 10 mins
move to 20' i will do 3 runs
are you saing that this will not give any indication at all of what changes to static ignition timing will do to an engines power output under load?
BTW - in your opinion is 10 mins enough cooling time, or too much?
oh, and will the results be affected in any particular way if a V-AFC is being used.
or for the sake of consistency, should this product be set to zero?
and just to get it REALLY certain, you are saying that increasing timing and increasing octane i will see generally "lower power level everywhere", even on non-stock engines?
or are your assertions ONLY in relation to stock, non-modified engines? (which you have not mentioned anywhere, but just thought i would check...)
This is a very stupid argument. We are obviously on two different levels understandings as to how ignition timing affects torque output.
Your wasting your time by doing these dyno runs. You will not get any results that are applicable to anything but your car.
My comment was that going from 91-98 octane and only advancing 2 degrees would cause a loss of power. Nothing more.
A tuned, modified engine would obviously not be running on 91 octane, and would have a well tuned ignition map so this entire thing is useless as advancing the base timing would mess it all up.
And I did not say that it couldn't be proven at all.
Do multiple dyno runs, I bet you don't get the same result. I'm saying that on a roller dyno, there are just far too many variables, which could cause the result to vary more than the variance in the results that are expected.
well, no - your original comment in dispute was:Quote:

If thats what you believe, then just go ahead and do it, stop structuring your questions to cause arguments...It's not a court room !Quote:

Obviously there is a point where advancing more doesn't help, but on a stock honda, some power can be had from advancing timing.
