UTEC in Australia!!! - knocking due to cold air

[rstlss]

I was starting to think that also, but we have +98RON fuel here also, which is a shame because alot of what u guys n girls use over there, cant be used here...
But u am finding that alot of your information is relevant such as dropping timing and other ideas...

I'll get that timing map up

rstlss did you make those timing changes i suggested a few posts ago?

I took my High Boost Map (which i am having problems with) and have now redone the timing and boost figures.

My boost figures look slightly better t han what they were - they were jumping by about 50 on the UTEC map.

My timing figures i have changed also. I have reduced the timing as follows...

            80%                 90%                100%
3750     17.5 to 16.5      17.5 to 16.5      17.5 to 16.5
4000     17.5 to 16.5      17.5 to 16.5      17.5 to 16.5
4250     18.5 to 17.5      18.5 to 17.5      18.5 to 16.5
4500     18.5 to 17.5      18.5 to 17.5      18.5 to 17.5
4750     19.0 to 18.5      19.0 to 18.5      19.0 to 18.5
5000     20.0 to 19.0      20.0 to 19.0      20.0 to 19.0
5250     21.0 to 19.0      21.0 to 19.0      21.0 to 19.0
5500     21.0 to 19.0      21.0 to 19.0      21.0 to 19.0
5750     21.0 to 19.0      21.0 to 19.0      21.0 to 19.0
6000     21.0 to 20.0      21.0 to 20.0      21.0 to 20.0
6250     21.0 to 20.0      21.0 to 20.0      21.0 to 20.0
6500     Left at 21.0 all the way thru to redline...

I have run this 2nite on the way to work, and has not shown any knock at all, air temps around 18C degrees. I also did some runs with the data logger and it is holding boost nicely at around 17.5psi and and not showing any knocks at all.
I am gonna get the car onto a dyno so i can check the fuel mixtures are still ok, but they should still be around 10.8 - 11.2:1

Would this mean that i might have solved my problems???
If so, in which direction should i head now with getting down to a fine tune???
Should i be looking at increasing some timing in parts and seeing if knocking shows up? Or do you think i wont get anything else out of it and i should just leave it???

Cheers

Tim!

sounds like it.

well, if you're anything like me, you probably won't leave it alone...

can you get a little more power? sure you can, 99% of the time... but it will be more prone to knocking. that's the tradeoff: power vs. stability/safety.
