B13/S13 known map addresses

Calum · 07-13-2006, 05:37 PM

Please do not post this on other forums.

By request, here's the big chunk of my list. Lots of this is only written down in my notes, I'll sort through all those eventually.

It needs the units and x-axes added, if someone wants to work those out I'll update the list. Or someone could put it in a better format. Excel maybe?

This is probably missing some of the newer stuff thats been documented, and may have some errors in it. Post it in this thread and I'll correct it.

Anybody want to sticky this?

$000A-000B - K-value
$001B - Injector null time
$001A - Injector voltage adjuster
$0038 - Fedback switches (binary flags, not a numerical value)

$05C0-05C1 - sometimes rev limit
$0056-0057 - KA24DE 5th gear rev limit

$0031 - sometimes speed limit
$05C9 - sometimes speed limit
$05C0 - sometimes speed limit

$0D00-0DFF - Primary ignition map
$0800-08FF - Secondary ignition map
$0490-049F - Ignition TP axis
$0480-048F - Ignition RPM axis

$03A0-03AF - TTP Max
$0A00-0A0F - TTP Min
$02F0-02FF - TP Limit (high boost fuel cut)

$0200-020F - Acceleration increase volume ???

$0A00-0A1F - First water temp revision ??? this is wrong?

$0220-022F - Spray water temp offset

$0230-023F - Int spray TP offset

$0610-061F - Water temp map 3 ???

$0620-062F - Water temp map 4 ???

$0C40-0C4F - Dwell duty cycle, SR20DET with coil packs

$0320-032F - Starting injector pulsewidth

$0660-066F - Idle map

$0310-031F - EgStart gain offset

$0330-033F - EgStart pulse Offset

$00A0-00AF - Throttle Open Offset

$00D0-00DF - Water temp RPM gain

$00B0-00BF - Low water temp fuel offset

$0390-039F - Q offset RPM table

$03B0-03BF - Sequential spray end

$06A0-06AF - Dashpot duty

$0690-069F - EgStart Duty Table

$0680-068F - Open loop ISC min

$0450-045F - Starting ignition timing

$0460-046F - Idle ignition in neutral

$0470-047F - Idle ignition in gear

$0510-051F - Electrical angle offset

$04A0-04AF - Cold start timing advance

$04B0-04AF - Deceleration (Cold?) ignition timing advance

$04C8-04CF - Idle stabilization timing retard

$0AC0-0ACF - No translation

$0AD0-0ADF - No translation

$0AE0-0AEF - No translation

Pictures for the no translation stuff:

If anyone can get those translated I'd appreciate it.

Edit: I want to figure out what $0090 and $0F90 are. They're both 16 byte long 2-D tables, no clue what the axis would be.

Wow! Thanks!
A bit more, I've discovered them today.

$4A0-$4AF - Cold start timing advance
$4B0-$4AF - Desceleration (Cold?) ignition timing advance

$4C8-$4CF - Idle stabilization timing retard
You know, your idle timing is jumping if you have huge cams: try to set this map to lower values - you find your timing pretty stable!

My current setup for JWT C3 Cams is:
$4C8: 00 00 00 00 00 00 02 04
Do not set it all to 00 values - it's my suggestion! ;-)

Calum, please test $4F0-$4FF and $500-$50F if you can. There are 2 ignition maps, I think. I have no time to test them - I'm going to competitions at weekend.

Added. I won't have a chance to do anything until monday. We need to document how to build an engine simulator to make this stuff easier. I wrote some code to do the distributor signals, I need to post it.

Good find on the idle stabilization!

What are the first four bytes at 04C0-04C4? Any idea?

JRios · 09-10-2006, 12:10 PM

EDIT, nevermind. Off topic.

Engine simulator??? I'm intruiged..

thinnertenor · 01-23-2007, 11:42 AM

question, when you refer to these codes applying to the S13, is that only the SR20 S13, or would this stuff be compatible on the KA?

src · 01-30-2007, 04:42 PM

Calum, any update on Rom addressess from you?
What about an emulator building progress?

Calum · 01-30-2007, 04:55 PM

Yea, I need to post an update for this.

Emulator is just about done. V0 has been running great for a while, V1 should be in testing later this week.

src · 03-08-2007, 05:23 AM

Calum, please post an update! Can't wait anymore!

PS: pls check your email. I've asked for dautherboard OrCard
schematic and layout files. Thanks!

Translation:
28:
基本減速減量率: Base deceleration loss ratio
補正率: Correction ratio
（小）　Small　スロットル開度　Throttle Aperture （大）　Large

29:
減速減量回転補正：Deceleration loss rpm correction
補正率: Correction ratio
低回転 Low RPM エンジン回転数　Motor RPM　高回転　High RPM

30:
減速減量水温補正　Deceleration loss Water Temp Correction

hope this helps.

Ah, thats interesting. 0AD0 is a percentage multiplier applied to 0AC0. I'll have to see if I can simulate this.

I was looking through the S13 xdf and I noticed these 2 items-

00D0 - Cold Start - Moving - Secondary

and

0FC0 - Throttle Enrichement - Fast Movement

are using the same address "00D0"

Perhaps xdf needs updating?
