yes the 61 was someone that didnt know how to tune knock out and put it to 61 so it never knocks.. we set that back to around 18. the car now has 0 knock with my tune.

Heres the additional stuff you want to add to the XML to display the knock settings.

<table name="Knock Load Table 1" category="Knock Control" address="407e" type="2D" level="2" scaling="Load8">
<table name="X" address="4d76" type="X Axis" elements="10" scaling="RPM"/>
</table>

<table name="Knock Load Table 2" category="Knock Control" address="408e" type="2D" level="2" scaling="Load8">
<table name="Engine Speed" address="4d76" type="X Axis" elements="10" scaling="RPM"/>
</table>

<table name="Knock Load Table 3" category="Knock Control" address="40b0" type="2D" level="2" scaling="Load8">
<table name="Engine Speed" address="4d76" type="X Axis" elements="10" scaling="RPM"/>
</table>

<table name="Knock Multiplier - Low RPM" category="Knock Control" address="177a" type="1D" level="1" scaling="uint16"/>

<table name="Knock Multiplier - Mid RPM" category="Knock Control" address="24aa" type="1D" level="1" scaling="uint16"/>

<table name="Knock Multiplier - High RPM" category="Knock Control" address="21de" type="1D" level="1" scaling="uint16"/>

<table name="Knock Adder - Single Gain" category="Knock Control" address="1780" type="1D" level="1" scaling="uint16"/>

<table name="Knock Adder - Triple Gain" category="Knock Control" address="177c" type="1D" level="1" scaling="uint16"/>

tom! just found out the adress is WRONG!!! after digging around alot! it made no sense why even the stock 9055 roms had a mid of 61

here ya go...

Code:

 <table name="Knock Load" category="Knock Control" address="407e" type="2D" level="2" scaling="Load8">
        <table name="X" address="4d76" type="X Axis" elements="10" scaling="RPM"/>
    </table>

    <table name="Load required for Octane update" category="Timing" address="408e" type="2D" level="2" scaling="Load8">
        <table name="X" address="4d76" type="X Axis" elements="10" scaling="RPM"/>
    </table>

    <table name="Knock Multiplier - Low RPM" category="Knock Control" address="177a" type="1D" level="1" scaling="uint16"/>

    <table name="Knock Multiplier - Mid RPM" category="Knock Control" address="24a8" type="1D" level="1" scaling="uint16"/>

    <table name="Knock Multiplier - High RPM" category="Knock Control" address="21dc" type="1D" level="1" scaling="uint16"/>

    <table name="Knock Adder - Single Gain" category="Knock Control" address="1780" type="1D" level="1" scaling="uint16"/>

    <table name="Knock Adder - Triple Gain" category="Knock Control" address="177c" type="1D" level="1" scaling="uint16"/>

Hmmm...yeah my tune is nice and safe now.

Waiting on my wideband and front pipe to go in and i'll clean up the fuel map, then get a bit more from the timing map...

Hey guys......I"m baaaaack into it.
TXS front pipe, LC-1, 4bar Omni Map sensor installed.
Ripped out the water spray and ran a cold air feed, boxed the HKS intake etc. etc. etc.

-Now first pull after installation shows its leaned out quite a bit, mid/high 12's through out the run until above 6k where it runs down to low 12's.

Selected the main chuck of cells that i'm trying to richen (3-6k, 180-220 load) and dropped the targets down by four points.
This richened the a/f ratio the next run, it was low 12's dropping into high 11's.
My target AFR number on the EcuFlash bin is "10.6-9.7" but my actual is ~2 whole points above this.

Does this indicate my fuel pump is on its way out? Presuming its stock as i've never looked, the a/f's are dropping up top though which made me think not.

I know the MAF scaling can sort this out but is that such an issue with a stock turbo/injector/pump setup?

Cheers.

no try pulling some more off and see if it goes richer. .4 isnt enough to take mid 12's to mid 11's. try .3 more

Cheers Tom.
I was just curious though as this is the first changes to the map you put down 2 months ago, was high 11's t the tail pipe then.
Very suprising how much the front pipe leaned it out. Not knocking though and running 14 deg up top.

Ok got the fuel map done I think, at least for WOT 3rd gear pulls.
Here's the VD of three pulls, Green was where I left it earlier this arvo, blue is the last flash to sort out the fueling, Red is another pull about 30min later with no changes, forgot to plug the LC-1 back in though.
Forget the crazy spike though, does that sometimes.

Any suggestions on that spool up a/f? Is that ok?
Was aiming at just above 13:1 at 3k, tapering down to mid 12's at peak boost and then 11.7 by 4k.
Then rocks between 11.5-11.6 until ~6500 where it tapers down again toward 11.2 by cutout.

Have attached the log for the Blue run.
Fuel is 98RON which is ~92.5MON.

Cheers.
