Your fueling seems to be really inconsistent between datalogs mate.
Try this one and see what it shows.

Also how ENDLESS getting on with the map I gave him?

OK. Your still getting knock before your recording your log so this time can you log your whole run and I'll tune out that knock as well.
Also try your WOT from nearer 2k. Do it in 3rd if you don't like the thought of it labouring.

Here's a map based on your last datalog though.

Hey. It's looking pretty good now. Richened it all up over 3500 a wee tad and took 1 degree out above 8k.

Should be pretty much done now mate.

If you or ENDLESS fancy trying my itr map give me a shout. Different cam angles than you guys. You might like it. You'll need to datalog it tho as the fuelling will need tweaked.
If you are happy with your own map though thats cool.

I'm at work at the moment but I'll check them as soon as I get home mate.
Is it at WOT? I'm surprised if it is as I already tuned out the knock in WOT.

You only had 1 knock during those datalogs mate, which I hasve made an adjustment for.
Your fuel is good although I added a small amount to it all to keep u on rich side of 13.2

Almost your knocks now are before your logging mate not at WOT.

If you want them tuned out you need to give me a datalog from moment you start car till the moment you switch it off and just do your normal driving.

Hi mate,

I'm working again just now but will check it out when I get home. Is your 2 counts of knock at the 3500 mark?

Also can I ask if you use the same quality of fuel all the time? Same octane rating?

Reason I ask is if I tune while your using say 93 octane and everything works fine, if you put in 91 octane there is a chance it'll knock due to the poorer quality of fuel.

You should always use the same fuel if poss and if you can't then tune with the poorer fuel as then better fuel won't affect the tune.

HI FONZ600...WELL FIRST OFF THE 1ST KNOCK WAS AT 2,283RPM - 4,305RPM - THEN THE 2ND KNOCK OCCURED AT 4,327 RPM - 8,600RPM THANKS FOR LOOKING INTO THIS MATTER. AS FOR FUEL I ALWAYS USE 89 OCTANE FUEL, NOTHING ELSE BUT THAT. EVERSINCE I BOUGHT THE CAR BRAND NEW, I'VE BEEN PUTTING THE SAME FUEL EVERSINCE. BY THE WAY IS IT REALLY BAD TO RUN MY CAR EVEN IT HAS 2 KNOCKS OR SO? JUST CURIOUS.

I wouldn't recommend WOT throttle if that is where you are getting knock.
I'll look at the runs later, 8 hors from now so you'll get that map when you get up.
It's bizzare as your knock seems to vary from nil to a few counts randomly unless your doing some runs on a flat road and some uphill.
Uphill runs in 4th will give the engine a good load and is prob best for highlighting knock.
That way if you tune for that you shouldn't get any knock on flat roads.

Hey again, well the runs I did was pretty much on a flat surface road. Other than that no bump whatsoever. Alright, so I'll check on the new map in the morning. thanks again bro.
