How to create an xml file with this code?

I made a little discovery recently - with an unmodified ECU, the lowest speed at which I can activate cruise control, is 37 km/h.

However, if I then get the car to slow down (going up-hill or by using the hand brake), it will keep CC activated all the way down to 33 km/h. So the tables that we have defined only sets the minimum / maximum speed of activation / engagement, but there is another limit defining the minimum speed at which CC stays activated / engaged.

So I opened my ROM file in a hex editor and started searching for value 33 represented as a 32-bit big-endian float - and there are 2.

One is at 0xC07A0 and the other is at 0xC375C and searching for these values as 32-bit integers, I did find them at 0x1AAD4 and 0x63040 respectively - I guess these are references to the addresses, so they are 'something' significant.

Now I'm stuck again and clueless about how to find out what these two addresses are and if one is related to cruise control lower limit, how to define it in the XML so I can than use RR to change / lower that value to 25. I'm pretty sure I can't just change it in the hex editor and expect to have it flashed successfully, surely there are checksums that would prevent that, right?

Hi guys.. has anyone got these cruise limit addresses or XML for AZ1G104K please

JDM Forester XT MT

From C1AD4 to C1AE0.

Why not 32, there are a few 32s in the vicinity of the other limits.

I did, but I figured that since Low Limit in the table is 37 and that is actually the lowest velocity where I can engage CC, the lower limit for CC functioning would also be the last round KP/H where it still works.

But either way I don't know what to do with that.

thanks for that - sorry it took me a while to test.

I have put into xml for ecuedit and I am assuming the values are as std 35 for the mins and 102 for the max as this is what the 16 bit big endean works out as i think.

I could only see 2 mins and 2 maxs in that area of the hex file that equate back to this although tbf I dont think in hex so cant be 100% sure.

Will changes the max values and test

When an ecu has the 8 Min/Max settings have we figured out what each does?


2005 Outback XT A2WC521R had the same hex starting at C19A8 (seems like all 2005 dbw turbo models may have this hex somewhere). The values seem to be stored as KM but I especially don't understand the 110 and 105

Added 33 to all max settings and confirmed the change was successful. Still curious when each of the four settings are in effect.

Hello gentlemen!
Definitions for cruise parameter adjustments were provided above.

Unfortunately, after adding these lines to the EE5K000K definition in Ecuflash, only the first four lines are displayed. All the others are hidden and invisible. After changing the speed values ​​from 114 km/h to 250 km/h, there are no changes. As there was a limit of 114, it remained so. Despite the fact that the parameters were changed.
Maybe I'm doing something wrong?

I would be grateful for any help in resolving this issue.

Hello, do you have Cruise speed definitions for A2UG000B? Thank you in advance.

Hello! I need Cruise speed definitions for A2UG000B too. Thank you.

Cruise speed address for A2UG000B is the same like A2UG000K

For the AZ1xxxxx series ECU, look for 43 C8 00 00 3F 80 00 00
The next 4 values will be the two Min and then the 2 max values

AZ1G502L for example, has them starting at c1c14, which then becomes:
