I have been doing alot of map discovery for my Evo7 GT-A (80700010) and have started to find the same maps for the more common definitions that we see here in Australia. Please test the maps carefully before fully implementing them. Also some of the scale ranges for these vehicles were not immediately obvious in the disassembly so they may need to be corrected, but the values I have used are the same as those working on my definition.

All need the "Enrich" scale which is actually a mislabelled timing trim scale. Most defs have it, if not add this line.

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

Interesting. Good find.

 

The Warmup Temp Control map is linked to (obviously) the Warmup Ignition Retard maps. Most definitions have these maps listed as Anti-Lag or Boost Enhancement maps, and these maps should also be changed to be viewed in Enrich (which is Timing Trim).

The Decel Fuel Cut Delay maps would be part of the solution for those with throttle hang issues. Lowering the numbers can force the fuel cut to kick in more quickly.

Let me know how these maps go.

 

I'm one of those with the throttle hang issues. Thank you.

 

Are the IX tables for an 88580015 or an 88590015? Thanks.

 

8858 Aussie model. It should not be too hard for someone to find the maps in other defs, I just cant do any testing at all in the cars. If enough people want it I will find some time to find for 8859 or others.

 

88590015 would be great.

 

Nice thanks for the 98640014 additions.

any map in which i can set stationary limits? for a JDM EVO 7 2001 model , i have one but the address feild is empty while i go edit it doesnt show any data - anyone here knowing what is the input in the address feild of stationary rev limit - also any maps for JDM EVO 7 GT-A version (Auto)

 

I guess you have 98640014 there is no static limit in the standard JDM ROM, any xml that you see that in is wrong...however JoeBee and tephra have sorted that out and tephras V5.10 has a ROM that has been tested to work on the JDM 7...you'll need to change the immobilizer code see the thread here 10th post down by cossie1 download those 2 files.

+1

As these also work for 90550001 and 98650014

 

For the Evo 9 - 88580015

<table name="Ignition Trim vs Engine Temp" category="Timing" address="3c80" type="2D" level="2" scaling="Enrich">
<table name="Engine Temp" address="71ca" type="X Axis" elements="8" scaling="Temp"/>
</table>

Table is never called, so it is unused.

<table name="Ignition Trim vs Air Temp" category="Timing" address="3c8e" type="2D" level="2" scaling="Enrich">
<table name="Air Temp" address="71ca" type="X Axis" elements="8" scaling="Temp"/>
</table>

Table is called. Will check it out.

Still looking over other tables...

 

I *KNEW* there had to be some ign tables for different temps.

Awesome find

 

Same here ... it would explain some odd timing values I get when my octane level is at 100
