Score one for the good guys No offense to the 1.3 folks

 

lol for those looking to pay for this upgrade, I compiled all the options available to the US here - https://www.evolutionm.net/forums/ev...t9as-read.html - is it possible to mimic these set ups using ecuflash?

 

Updated .xml -> 401403_2-23-10.zip

Figured a few more axis out.

Table Main: ??? x Vehicle Speed
Tables A: Throttle Position x Vehicle Speed
Tables B: Table B, X Axis Tables x Vehicle Speed
Tables C: ??? x Vehicle Speed


Table B, X Axis Tables are used to find the X axis for the B Tables.

Calc = X Axis 1 * X Axis 2 * 4

Axis 1 Tables are Wheel Speed Difference (Rear - Front).
Axis 2 Tables are Vehicle Speed.

So simply, the B Tables X-axis is Wheel Speed Difference times Vehicle Speed.


Still working on the Main Table. Tables C does some jump through the rabbit hole trickery I'm not following, maybe someone else can try to figure it out. (Acamus?)


sba if you could make a ACD Mode button, we could find out what Gravel, Snow, Tarmac, corresponds to. (ie .1, .2, .3)

 

Sure, can you email what you have?
I was doing 401501 :P, maybe we can exchange disassies.

sba has done acd mode, it is on mut 3

EDIT:
We have been doing some more research in ADC routine yesterday,
As I wanted to get complete ADC polling variables to be known.
There are more - maybe AYC stuff.

But it seems the ecu is protected somehow we have not been
able to use modified MUT to retrieve it as logging stopped
working with ROM modified.
I believe we need Colby to get the flashing working now.

 

I think the big table is the AYC Proportioning map, ie torque to the outside wheel.
X=Steering Angle (0-512*)
Y=Speed (0-250.2kph)

The G-Force sensors have to get involved with ACD somhow too.

 

right folks iv done a bit of digging on the net and found something very interesting for you all.it seems there are 6 inputs to the ACD/AYC control

1.steering wheel angle
2.vehicle speed
3.wheel speed
4.longitudinal G
5.lateral G
6.throttle opening

hope this helps

 

^ and lateral G Force

 

just noticed

 

MUT 0x22 - ADC_Channel_9
MUT 0x23 - ADC_Channel_1
MUT 0x24 - ADC_Channel_3
MUT 0x25 - ADC_Channel_2

MUT 0x1B - something calculated from ADC_Channel_2
MUT 0x1F - something calculated from ADC_Channel_2
MUT 0x20 - something calculated from ADC_Channel_2

 

Also hand brake switch and brake switch.

 

We are not sleeping for sure, we are working to find out all that is inside this ECU.

 

everything thats in the ecu should be in the diagrams i provided.after all its from a mitsi technical document

 

here is the doc in full

Hamish is getting his ACD ecu today to test with EvoScan, he is going to add support 1.3u and op2 for it. i'm gonna beta test and I'll let you know if its working.

 

Im glad to hear it will have 1.3u support.

Go hamish
