Ken,
I'd sent you a PM about 3 weeks ago... I'll PM you again with my ftp address logon. Yeap, am in KL. Mail me directly if you have question sub7owner[at]gmaildotcom.

 

Sub7,

Give me a ring 016-2819119. I pass the DVD to you so u can upload it to ur server. that would be much easier. so the rest of the guys can download.

Thanks

 

I haven't posted for a while, but work still continues with the map discovery, albeit a little slower (been very busy). I had plans for today to do some more research with the coil charge time with a buddy of mine who works for a major aftermarket ECU manufacturer. At least he has a far more accurate scope than I do.

The trans stuff is going to be slow going, so dont expect anything spectacular for a while.

 

Matt/Aaron, I got the copy of manual from Kenyong. Please PM me to get a copy of the manual. I have restricted bandwidth quota to share

Thanks to Ken for generosity to share with us.

 

Just a quick update for the Evo 7 GTA.

I am now using the OpenPort 2.0 cable and at this point using V1.40 Ecuflash. I had to create a new read template which so far seems to be working, at least for reading. I have not done a Write with the new cable yet but will give it a try in the next few days. If you get an OpenPort2.0 cable, put this Read template in the appropriate directory (rommetadata/read templates). This will allow the full 512k rom read.

 

Hi , I'm newer here , can anyone help me. I have problem with accelation map , when i look at acceleration enrichmap and try to fix it , no response , no change when i look at mitsu logger , no effect . Is acceleration map is that map . Now i cannot run my car becase when i put pedal quickly i got black smoke , Thankyou Mattjin for a lot of information.

 

What address is the map you are adjusting? If you are new to this be very wary, because some of the maps are mislabelled and there are many more that are not defined yet.

One of my next target jobs is the acceleration mapping. Just no time lately to do anything.

 

Some corrections, some more will follow (I am one of those hex nerds)
80700010:

<table name="Lean Spool Trailing Time - Rich Side" category="Fuel" address="3b2e" type="2D" level="2" scaling="uint8">
<table name="Engine Speed" address="598e" type="X Axis" elements="14" scaling="RPM"/>
</table>

<table name="Lean Spool Trailing Time - Lean Side" category="Fuel" address="3b42" type="2D" level="2" scaling="uint8">
<table name="Engine Speed" address="598e" type="X Axis" elements="14" scaling="RPM"/>
</table>

it seems that IPW mcsec scalings from your posts can be used here so:

<table name="Lean Spool Trailing Time - Rich Side" category="Fuel" address="3b2e" type="2D" level="2" scaling="IPW mcsec">
<table name="Engine Speed" address="598e" type="X Axis" elements="14" scaling="RPM"/>
</table>

<table name="Lean Spool Trailing Time - Lean Side" category="Fuel" address="3b42" type="2D" level="2" scaling="IPW mcsec">
<table name="Engine Speed" address="598e" type="X Axis" elements="14" scaling="RPM"/>
</table>

 

and some more axis corrections:

<table name="Lean Spool Load" category="Fuel" address="3b56" type="2D" level="2" scaling="Load8">
<table name="Engine Speed" address="5c72" type="X Axis" elements="9" scaling="RPM"/>
</table>

<table name="Lean Spool AFR" category="Fuel" address="3b66" type="2D" level="2" scaling="AFR">
<table name="Engine Speed" address="5c72" type="X Axis" elements="9" scaling="RPMStatLimit"/>
</table>

 

You might want to re-check those addresses because they don't have anything to do with Lean Spool from what I have seen. They point right into the middle of cranking enrichment map territory. More like 3dxx than 3bxx for Lean Spool.

 

I just started with that and I have observed duplicates and some discrepancies but from what I have seen the adreses were incorect so I wanted to help. I know that the 2d tables are labeled wrongly but at least adresses are correct.

 

You might have to check you are using the correct rom file and using the correct info for 80700010. Be sure you are using the 512k rom too, as this is the correct full rom. Those maps are definitely not anything to do with "Lean Spool" in anything I have.

Be sure you are up to date and not using too much info from the beginning of the thread. Back then I was new to this and learned ALOT since then.

 

Some new maps for 80700010:

DelayTime scaling was found only through experimentation, but through more thorough disassembly someone may find the true calibration. It appeared to be based on 128 = 1 minute, 255 = 2 minutes.


<scaling name="DelayTime" units="sec" toexpr="x/128*60" frexpr="x/60*128" format="%.1f" min="0" max="120" inc="1" storagetype="uint8" endian="big"/>

<table name="Closed Loop Fuel Start Delay #1" category="Fuel" address="3ac6" type="2D" level="2" scaling="DelayTime">
<table name="Engine Temp" address="5c58" type="X Axis" elements="8" scaling="Temp"/>
</table>

<table name="Closed Loop Fuel Start Delay #2" category="Fuel" address="3ad4" type="2D" level="2" scaling="DelayTime">
<table name="Engine Temp" address="5c58" type="X Axis" elements="8" scaling="Temp"/>
</table>

 

Found another few small things today while checking over the boost control routines. What I found are two 1D maps that control whether the boost control is enabled or disabled based on the Octane number. One will turn off the boost control if Octane drops below a certain value, and the other will turn it back on once Octane raises back above a certain value. I tested this today and it works. Yes I know this range of address numbers are usually in "uint16" but I have chosen to do the maps in unit8 so that the scale line works with other maps.


<scaling name="Percent (256)" units="Trim %" toexpr="x/2.55" frexpr="x*2.55" format="%.0f" min="0" max="100" inc="0.39" storagetype="uint8" endian="big"/>

<table name="Boost Control Disabled Below Octane" category="Turbo" address="1a5f" type="1D" level="3" scaling="Percent (256)"/>

<table name="Boost Control Enabled Above Octane" category="Turbo" address="1a61" type="1D" level="3" scaling="Percent (256)"/>
