Hi.
Once I tried coding with nettodat, but no luck.
I tried to code the default front distance/time setting on my e65. Did not succeed either way.

I coded the default distance to the furthest no problem. Just used the US option (3). But maybe you tried to get a lower distance and thus needed nettodata coding? I have done nettodata coding to another sensor that had broken lens heating that I tried to deactivate.

If I remember correctly I chose the special functions, nettodata coding, specified nettodata.man and the ACC2_60_C28 and coded.
I think I got an error message but reading the module afterwards showed that it had taken the flash.

Well the error just said that there were bytes that was not changed so not really an error.

I had some other errors saved also but they seem to be from me doing it wrong

I'll try it once again. I wanted to code closer distance default setting, when I enable ACC.
Thanks

Try to change the min speed setting while you're at it [emoji6]

I changed the min speed down to 10km/h and coded with nettodata by reading the module then changing the coding and then selecting:

Basic functions
CoapiCodeSgByNettoData
Type in NETTODATA.MAN
And ok

Anyway. Even though it took the flash it still won't engage the cruise control under 20km/h. So it must be prevented by something else. I'll try to see if I can find something else.

Edit: it did not take the flash after all

 

Try using PerfektToolBox google it

 

I take back the statement in my previous post. Nettodata coding did not work. When I double checked it after a drive.

So I went back to NCS dummy and edited the file to include wert_03 with data (dec) 10.
I then coded with FswPsw.man the normal way and tada; it worked perfectly. I can now activate and use it from 10km/h [emoji3][emoji7]

What line did you change? I wonder if it's possible to code to full stop and go without touching pedals?

 

Vsetz min. Or something similar with the description in NCS dummy of minimum activation speed. Speed = data (dec) - linked to speed unit

Something like that is the line named.

Open your ACC2 module description file in NCS dummy without loading any trace file and find that line. Right click on the line, add costume parameter. And name it wert_03 and add your value eg (dec) 10, (hex) 0A.

Or as you want 0km/h you add value 00.

That said, I don't know how the car will behave at those low speeds because the idling speed (no gas, no brakes) is around 8km/h so I don't know if the acc will keep on the brakes in order to maintain a lower speed. Since it's not really intended to go that low. But by all means, pleas try it and report if it works.

Thanks, I just read somewhere that stop&go introduction required some effort even for the big manufacturers. So there are some issues to consider probably more than just coding.

That makes me wonder if it somehow would be possible to retrofit Stop & Go system into the E65. But that would require looking up what controllunits it excepts being able to talk to.

Yeah, I coded it to 20 km/h. Even that is pretty low, the cluster often throws a warning sign when the (not that close) car in front drives below 30 km/h

Maybe I should change the coding for the maximum deceleration value as well but I'm reluctant to change too many things

If you change deceleration it might become very hard braking at high speed since it's based on m/s²
But hey go for it but be prepared on it slaming the brakes at high speeds since it basically already does. Although it is possible that the stop and go version has bumped that up in order to do emergency braking.

 

Hi!
Is there anybody besides me who uses acc with normal cruise control stalk? I tried to code the initial distance(02) but when I set a new value in nettodata ncs gives me errors. I also tried another way, I disassembled the ACC2E90.C47 and set new values (00, 01) and after that I tried to code with the new value. Coding was successful, but when I go for a test drive and turn on acc it always uses 02 as initial value.

 

Coding was successful, but when I go for a test drive and turn on acc it always uses 02 as initial value.

Just in case, it happened to me (with the normal stalk), I just had forgotten to turn the car off and on again.

 

The car left the factory with ACC.

I'm just stating that it kept the 3 second interval even though I had coded 2 seconds until I removed the key and inserted again. I thought it was worth mentioning since the symptom was similar (but, again, not due to the stalk)
