Probably not. The ignition trim should only be active while the fuel is cut, but you can always try. Just lift the decel rpm offset to as high as it goes and increase the ignition retard and see what happens. Remember, this is an offset from target idle. All that is left then is to find the part of the code that turns on the antilag solenoid. Interestingly, the 89970010 rom runs very different values than our roms. It runs far more retard than ours with around 30 degrees of retard. This is usually only done to smooth the transition from closed throttle with the fuel off, to when it turns back on, but 30 degrees is alot compared to our 10 degrees. I havent tried just raising the rpm offset myself yet to see which maps continue being used or not. You can always increase the Delay maps so the fuel cut takes a long time to activate.

The scales are 100% correct for some of the maps. I am not sure about the enrich map as I couldnt find a reference in the code. I only know it is enrichment because of testing and took a guess at it being versus engine temp as per the offset.

I stumbled onto another map today for 80700010. A 2D map that determines what temperature range to use the warmup ignition retard 3D maps.

<table name="Warmup Ignition Control vs Eng Temp" category="Timing" address="4a02" type="2D" level="2" scaling="uint8">
<table name="X" address="5cd0" type="X Axis" elements="8" scaling="Temp"/>

Wow! Thks. Its getting more interesting now hehe BTW airtrek cams lifts are lower than GTA. I have since swapped them with e8 cams. Improve top end power especially 4th and 5th gear. I also up my timing to 3 deg. Leaning from 80-100 load 1000-4000 rpm add 2 points.

I am trying out the fuel maps for n12, 345.

Do you know a place called Hiper Racing?

The more I look around the 8997 rom the more I can see. There seems to be more maps in it than the 8070 rom. It would takes months of work to find use from most of them, but as I find maps for 8070 I will do a quick look to find them in 8997. You just need to verify they work with thorough testing.

I am pretty sure I found another 3D map for 8997 in the hex just before the ignition map that was listed as Do Not Use. They are linked in the code, so maybe change the description so you know that. It appears to be one of the "knock filters" but from my experience some of those maps are not knock related.

For 89970010:

OK, I have a HUGE find! Found the ignition trim maps vs eng temp and vs inlet air temp for 80700010. These are tested and working perfectly.

Whats the scaling data for Enrich? I cannot get the data display correctly.

Thks.

Mattjin

I am sure I posted it a few pages back

Mattjin

Was Page 5

scaling name="Enrich" units="deg" toexpr="x-128" frexpr="x+128" format="%.0f" min="-128" max="128" inc="1" storagetype="uint8" endian="big"/>

I think whoever created it thought it was a fuel trim scale offset from 128 and called it Enrich. But it turned out to be a timing trim in degrees but I just kept the name because alot of the defs already have Enrich.

Another big find today. I now have the Thermo Fan map!!! Tested and working perfectly.

<table name="Thermo Fan Duty" category="Misc" address="56d6" type="3D" level="3" swapxy="true" scaling="Percent (128)">
<table name="Thermo Fan Duty" address="6000" type="Static X Axis" elements="3" scaling="RPM">
<data>On</data>
<data>Off</data>
<data>On A/C</data>
</table>
<table name="Engine Temp" address="5cae" type="Y Axis" elements="12" scaling="Temp"/>
</table>


I am thinking of changing my name to either Captain Cook or Columbus : Discoverer of New Maps :-)

Mattjin

Might need this Scale if not already in the definition

<scaling name="Percent (128)" units="%" toexpr="x/1.28" frexpr="x*1.28" format="%.0f" min="0" max="100" inc="1" storagetype="uint8" endian="big"/>

Incase some people didn't know, the thermo fans on these cars are PWM duty driven, and as such the fan speed can be controlled. This scale converts the 128 based numbers to 100% to reflect duty cycle.

Your finding some good stuff mate.

Once you are done, would you be willing to go back through 90550001 and see if any of these latest maps are in that rom too ?

hotsync

Mattjin aka Captain Cook hehe

Thks mate! Which version are u using? Mine 1.29a which I think is very stable,

Mattjin

I use v1.34 and have never had problems.


I will find the thermo fan maps for the Airtrek when I get some time. Just remember I cant test them so you need to do that yourself when I find the map.

Mattjin

Cossie, I think I found your thermo fan maps but to be sure answer this, do your fans start to come on at only 73C?

If so, then this could be your thermo fan map. You need to add the Percent 128 scale from a few posts ago to view it correctly.
