Hello all,

Looking for the location/definition of the post start enrichment tables for my 2011 STi. Did some digging and can't find any previously defined other than hot restart. Any help is greatly appreciated. If this has been defined, please point me in the correct direction.

Thanks!

Sorry mate, I've been in the process of moving house, just haven't had the time to do this - I'll see if I can this weekend.

Not a problem at all my friend. I wasn't going to pester you to death, as I figured you were busy based on the quick response you've given in the past. Figured I'd ask here too. Get to it if you have a chance, otherwise no worries. Trying to spread the load, you've helped me a ton already. :-)

No worries, I'll figure that out and email if I run into any issues. As always, thank you so much!

Oren,

Just to confirm, should I be working with something like this:

Code:
 <scaling name="Post_Start_Enrich_Decay" units="units" toexpr="x*0.00024414062" frexpr="x/0.00024414062" format="%.4f" min="0" max="255" inc="1" storagetype="uint16" endian="big"/>

      <table name="Coolant Temperature" address="CC6B4" type="X Axis" elements="16" scaling="CoolantTemp(DegreesF)"/>


My units appear to be off and the Post_Start_Enrich_Low_Speed_Decay_Initial_1A table location appears different than the rest. I'm sure I'm off base here. Just trying to find out where. I took the CC6B4 as the coolant temp address and replaced it down the line. Just to confirm that the xml code above is for the correct model and done properly by my hand.

Thanks!

Awesome thanks!

How do I go about changing the units on the X axis to something tangible rather than "units", how do I determine what those should be with no working reference? I'd like to know for future revisions.

Thanks!

It should be picking up the correct scaling, unless there is something wrong with your 32bitbase - see the CoolantTemp(DegreesF) scaling?

That's what I figured. I believe I have 2 sets: CoolantTemp(DegreesF) and CoolantTemp (DegreesF)[note the space]. I can test the other former when I get a second. It shows the temperature correctly and that looks good but the actual data below the temp is in units. Maybe an additional scaling is off?

Check in the 32bitbase for that scaling whether it is correctly filled in, or says units - that's where it's getting it from.

I figured as much. I'll take a look when I get to the office and have a sec. This is what I'm seeing but I'm sure it's something with the 32bit base:

These are the units I question. I can deal with it being formatted how it is, just wondering what the actual values are called in my OCDness.

Thanks.

The data unit conversion (multiplier and offset) is in the post from td-d. They are part of the table reference in the ECU (see below).

Thank you! Another elementary question.. With more understanding comes more questions :-).

So below, what determines the multiplier and the float point from within the base?

Code:
<scaling name="Post_Start_Enrich_Decay" units="units" toexpr="x*0.00024414062" frexpr="x/0.00024414062" format="%.4f" min="0" max="255" inc="1" storagetype="uint16" endian="big"/>
   <scaling name="Post_Start_Enrich_Decay1" units="units" toexpr="x*[b]0.00390625[/b]" frexpr="x/[b]0.00390625[/b]" format="%.3f" min="0" max="255" inc="1" storagetype="uint16" endian="big"/>
   <scaling name="Post_Start_Enrich_Decay2" units="units" toexpr="x*0.00000095367432" frexpr="x/0.00000095367432" format="%.5f" min="0" max="255" inc="1" storagetype="uint16" endian="big"/>
   <scaling name="Post_Start_Enrich_Decay3" units="units" toexpr="x" frexpr="x" format="%.0f" min="0" max="255" inc="1" storagetype="uint8" endian="big"/>
   <scaling name="Post_Start_Enrich_Decay4" units="units" toexpr="x*0.0078125" frexpr="x/0.0078125" format="%.3f" min="0" max="255" inc="1" storagetype="uint8" endian="big"/>
