Ignition Retard Vs. Air Temp
 
Mrfred, other disassembly gurus...

Have you guys seen this table yet? Mrfred can you trace it and see if it does what it looks like it does?

retards timing based on intake temp, I know the DSM's did this..

http://www.norcalmotorsports.org/use...vs_airTemp.gif

Here is the code for 88590015

Code:
        <table name="Ignition Retard vs Air Temp" category="Timing" address="3c8e" type="2D" level="2" scaling="Enrich">
                <table name="Air Temp" address="714a" type="X Axis" elements="8" scaling="Temp"/>
        </table>

nice!

The DSMs has ignition retard based on air temp and on coolant temp. So, I'm sure the Evos have it as well.

I can find that table for 96940011 if you would like.

Well let's see if it's correct.

It is showing -1* at 100F intake temps, which I personally have never logged. I regulary see 100F intake temps in the dyno room.

The address for 96940011 is 388a. You need the 'enrich' scaling defined though. I have a scaling called 'TimingTrim8' which fits.

Very nice find.

Mattjin mentioned this table in his thread regarding a bunch of new tables he'd found recently.

Yup, then I applied intake temp instead of water temp so it made more sense and found the correct address for the timing.

rom
 
I added the definition that you listed above to my rom 88590015 but when I bring up the table in ecuflash I don't see any numbers in the table. There are Xs in every cell probably indicating to me that the definition is not correct.

Nice find!

You need the scaling:

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

temp
 
I put the scaling in but it's still not working. I think I need the scaling for temp as well.

RazorLab Sep 30, 2008 03:32 PM
temp scaling is just Temp.

Make sure your endians, etc are correct.

hearnoevo Sep 30, 2008 03:44 PM

Got it! Thanks! For some reason I put the scaling name after the table command and it wasn't working. I moved it to a row before the table commands and now the numbers show up.

Which I would have noticed if I'd have read a little more closely rather than drive-by-posting while doing a million things at once. ;) Good stuff. :D
