ECUFlash Definitions

[BCX]

More romids added
Moved address info to specific roms rather than in base xml.
Went through this thread and captured everything.

For the fan control, we can add this into the official xml:

<table name="Thermo Fan Duty" category="Miscellaneous" address="124b0" type="3D" level="2" swapxy="true" scaling="Percent (128)">
<table name="Conditions" type="Static X Axis" elements="9">
<data>Main Fan 0-50kph</data>
<data>Main Fan 50-80kph</data>
<data>Main Fan 80->>kph</data>
<data>A/C Fan 0-50kph</data>
<data>A/C Fan 50-80kph</data>
<data>A/C Fan 80->>kph</data>
<data>Main+A/C 0-50kph</data>
<data>Main+A/C 50-80kph</data>
<data>Main+A/C 80->>kph</data>
</table>
<table name="Engine Temp" address="2d0d6" type="Y Axis" elements="12" scaling="Temp"/>
</table>


And we can use Evoscan, request ID 84 to show the Thermo Fan Duty.

I've added this in, but I think there might be a better way to represent this data as a table.
In the newest uploaded defs, there are a bunch of 1D tables that represent the vehicle speed switchover points.

Agree. From the Fan controller schematic, there is only 1 PWM output from the ECU, so, there shouldn't be any "main", "A/C", "main+A/C", etc, and yes, 1D table is enough to configure it.

new version uploaded. fixed some other stuff up.

new version uploaded. fixed some other stuff up.

Just downloaded and tested out the new XMLs - but EcuFlash doesn't like them?
Shows 'The current map description is invalid or incomplete'.
Am I missing something?

 

[BCX]

What version of ecuflash you running?

Some of the tables might say that as I'm working to complete them but 95% work.

Any output in the log?

 

[BCX]

Uploaded a new version with some other stuff.

@wintertidenz the issue might have been me using the < and > characters table name. I've ensured my tool replaced these with &lt; & &gt;

 

[wintertidenz]

Sorry didn't see this till now. Will give it a shot now and let you know!

 

[wintertidenz]

Looks good now - thanks for all your hard work.

A lot of menu for engine tuning on xml, some correctly addressed and some are not. just wonder do we need all of that menu? my galant is MT so i notice menu i often use are:

1. fuel map
2. timing
3. injector scaling
4. stock boost control lift off
5. radiator fan tweak
6. speed and rpm limiter lift off
7. knock indicator with CEL, but i hate to use it because it blink all the time on vacuum underpower. so i remove it for own use.

i maybe missing something but any other menu that we truly need it?

so what you guys think about it?

Can you elaborate what isnt address correctly?

7. knock indicator with CEL, but i hate to use it because it blink all the time on vacuum underpower. so i remove it for own use.

this isnt a feature of an OEM rom, you'll need a modified rom to have this feature.

i maybe missing something but any other menu that we truly need it?

so what you guys think about it?

I'm not sure what you mean. do you think we are missing maps, or the order is wrong?
In future revisions, i'll be trying to put some form of order to the tables/categories - open to suggestions for this.

Hi Guys, Let me know if this is not the best place for this post.

I'm having a bit of trouble with Scaling in EcuFlash and I need a bit of help understanding. I've tried to solve this by myself but no luck.

I've loaded up Bill's recent "vr4base" and "20030013" .XMLs (excellent that we have these!) and my Load scaling is 440?

Got a screenshot?

Hi Bill,

I did have the maps up earlier but I thought these ignition maps could be considered Steve's IP so I wasn't sure and pulled them down.
Here is my ignition map using your recent Defs copied into "C:\Program Files (x86)\OpenECU\EcuFlash\rommetadata\mitsubishi\galant"

If I put the stock defs that come with ECU flash in instead:

If I log ignition timing with EcuScan:

I've tried to solve it myself by looking at the .XML's themselves and also the "edit table metadata", I can see what the differences are with the numbers, but I have no idea what it all means:

So I was wondering:

• How do you change the scaling of the Load_16bit (and do I even need to?)
• And do I need to know what scaling (Load & Rpm) was used when my car was tuned by Steve and the maps were created? Would he have used 220 load as the maximum or 300 load or 280 etc. etc.

I'm just trying to experiment by pulling a bit of timing out of my tune at light loads/low rpm to see if this makes my car a bit more friendly to drive around town:
RPM oscillation on and off light throttle:

Thanks Bill.

 

[BCX]

No worries, ill have a look at it when I get a chance to pull out my laptop.

Not uncommon to rescale the load axis past 220.

I've been using stock ROMs to test the defs but I'll recheck the scaling is correct and then open my tune to double check.

Cheers,
Bill

 

[BCX]

@GLen20 well spotted, the scaling seems to have a problem. I'll fix up the defs and upload them again.

 

[BCX]

@GLen20 Uploaded a new version, check it out and let me know what you think. Added you as a credit to the defs

Had a few different scalings defintions for Load, wrong ones applied to Openloop, BDEL and fuel axis. Hoping it's correct now.

Can't help you with your issue with the oscillation, might be one for @TME_Steve

PS. Steve rescaled my load axis when running the standard size maps. Rom I'm currently running has big maps.

 

[GLen20]

@BCX Thanks Bill. That is very very much appreciated. And adding me for credits, wholly undeserved, but I'll take it

You guys are legends.

 

[GLen20]

Does anyone have any experience regarding how relevant / accurate the actual numbers in the Timing Maps are?

ROM data:

Logged data:
2250rpm 30% Load
= 35 degrees?

During log car was warm, 2nd gear, steady throttle, no AC, 15 ambient, sea level.

Do we know if there is something else in play here that would add timing?

 

[GLen20]

Hi Bill @BCX
I've done some further testing.

Both HO maps set to this:

Both LO maps set to this:

Written to ECU and then re-read to confirm changes applied.

2nd gear, 30km/h - Has not changed the timing?:

Not sure whats happening. I don't think I'm doing anything stupid / wrong.

I've compared your 20030013.xml and vr4base.xml files with the ones that come with ECUFlash and with my untrained eye, can't see any problems.
I did notice they do have a specific "23810004 2002 JDM Galant VR4.xml" and my car is a late July 2002 model (40th last car built), but I can't see any differences with addresses or anything (that seems like it would matter) with that 2002.xml either.

The reason I'm chasing this so much is because I have had a nightmare run with the timing doing strange things, tune, detonation, re-tune. detonation, good, hang on - detonation, pulling -8 degrees everywhere, good, cam seal replaced (CAS re-seated....?) retune.... @TME_Steve scratching his head.

Detonation is all good now, but the thing is a bit of a pig low rpm / light loads and hunt/surges on steady throttle at 1600-2500rpm.

I don't know if it is even timing related.
But I'm thinking about either throwing a carby and distributor on it, or setting the whole car on fire.

If you get a chance to have a look that will be very much appreciated. Thanks again Bill.
