Thats nice Ceddy, looks the goods to me, well done.

 

My EvoIX Edm to -20 degrees

Pug did you use the Scaling I posted in message #60?

And did you change only one address?

88590015 is 133E, stock value 00CB
Not sure if address is universal or different in other ROMs.

Have you tried lower then -20?
The maximum possible retard should be -27, but not sure if there are additional checks that would limit it before that.


Sorry for so many questions, I don't have an Evo to test on.

Thanks.

 

Using 235 as the retard limit on an EDM IX i've logged -22° before, however it was only for a second or so, before it changed and held -18°

 

I have not tried to lose timming -20 in the map, I'll try another day ...

My ecu took 88840617 ALS (88840013 stock) max retard 1 and 2 = 233


The explosions are very strong!

 

did anybody try to change 0x2438 (uint16) and get any success?

96530706

 

hmmm interesting

 

any luck with this on 88570008?

if someone guides me in the correct direction i can figure it out .... hopefully!

 

Bump!

 

good info

stock ecu has came ALONG way

 

90550001 timing retard limit to 255 or -29 gives -10 deg logged no lower

 

So are we going to get a table to be able to make this adjustment? If we get a table, I am willing to test the heck out of it. I am not keen on going into the MUT to make change.

 

hey guys. is there a table for setting that limit? I'm on 94170015 on tephra 5.10 and I can't find it. Do I neet to update to v6 or v7??

 

I've been sniffing around the subroutine that sets the ignition retard limit, and it appears that in the newer ROMs, there are two ignition retard limit tables that are used for two different operating conditions. Not sure yet on what conditions these are, but here are the two tables for the 8859XX15 and the 9653XX06. They may both need to be set more neg for ignition to retard further under all conditions. Note that the max possible neg value is about -28 deg. Should be easy for people running newer JDM, EDM, and ADM ROMs to find the additional table by comparing the offset between the two addresses.

8859XX15:

<scaling name="IgnTimingECUa" units="deg" toexpr="61-x*90/256" frexpr="(61-x)*256/90" format="%.1f" min="-30" max="50" inc="1" storagetype="uint16" endian="big"/>
<table name="Ignition Retard Limit #1" category="Timing" address="205e" type="1D" level="1" scaling="IgnTimingECUa"/>
<table name="Ignition Retard Limit #2" category="Timing" address="133e" type="1D" level="1" scaling="IgnTimingECUa"/>

9653XX06:

<scaling name="IgnTimingECUa" units="deg" toexpr="61-x*90/256" frexpr="(61-x)*256/90" format="%.1f" min="-30" max="50" inc="1" storagetype="uint16" endian="big"/>
<table name="Ignition Retard Limit #1" category="Timing" address="2438" type="1D" level="1" scaling="IgnTimingECUa"/>
<table name="Ignition Retard Limit #2" category="Timing" address="173e" type="1D" level="1" scaling="IgnTimingECUa"/>

88570008-88570014, 88580013-88580015, 88840016, 88900006

<scaling name="IgnTimingECUa" units="deg" toexpr="61-x*90/256" frexpr="(61-x)*256/90" format="%.1f" min="-30" max="50" inc="1" storagetype="uint16" endian="big"/>
<table name="Ignition Retard Limit #1" category="Timing" address="2038" type="1D" level="1" scaling="IgnTimingECUa"/>
<table name="Ignition Retard Limit #2" category="Timing" address="133e" type="1D" level="1" scaling="IgnTimingECUa"/>


9417XXXX has only one ignition retard limit table:

<scaling name="IgnTimingECUa" units="deg" toexpr="61-x*90/256" frexpr="(61-x)*256/90" format="%.1f" min="-30" max="50" inc="1" storagetype="uint16" endian="big"/>
<table name="Ignition Retard Limit #2" category="Timing" address="173e" type="1D" level="1" scaling="IgnTimingECUa"/>

 

great work mrfred....

now anyone can help me find it for 8857?
