Coding question - esys

Hi

I have ordered cable etc and esys off the net to change a few things on my 430d

Just wondered about the risks involved?

I'm an IT manager so usually competent at following instructions of this nature so my question is if everything is followed as per the instructions is there still a chance something could break?

Simple coding is pretty simple, and safe - flashing is riskier, and I wouldn't attempt without some experience. Understand the difference between VO coding, and FDL coding, and never press the 'Code Default Values' button (it doesn't do what is sounds like it would do).

It sounds like you want to do some simple FDL coding, that should be very safe. A tip, when you press 'Read Coding Data', it creates a NCD file in your CAF directory - that is the file that you edit when you edit the FDL. This file is also used to code the ECU with 'Code FDL'. So, before you edit it, make a copy, then if you ever want to go back, you can press 'Read Coding Data', replace the NCD with your backup, and then press 'Code FDL', and you will be back to your original state.

Yes, powersupply connected to the car (e.g. this).
When you turn on your ignition (which you had to do to code or flash) the car has a high consumption of power (F10/11 up to 60A in the first five to ten minutes).After ~15 minutes it sends some of it`s units to "sleep" so that the needed power goes down to ~30A or less.If your battery isn`t the newest or you need to much time to change your settings it could happen that your car will "break down" and if this happens while you are flashing or coding you could break your car to luxary garbage :).

Sorry for my bad english ... not my native language :D.

Ok well Im not spending 200 pounds on a power supply just so i can turn off Automatic stop start, is that normal practice to use one of these things? what sort of time frame do I have without a powersupply?

My car is only 3 years old, 22k miles and all service history so the battery should be ok....

20A isn`t enough and the 80A is only for starting, not permanent.
I´ve often read, that working on the carcomputers isn`t a good idea while the engine runs.
I`m not sure what the powermanagment (EfficientDynamics) will do.To much risk for me.
When i disabled my SSA the car was connected to a 60A Laboratory power supply.
The guy that coded that for me is a real professional and he gaves me a lot of advices.
One of them was not to do dangerous things with only the ignition turned on.Because of the fact that he really knows what he is doing i believe him ;).

Correct. Flashing can take an hour or more, programming only takes a couple of minutes for even headunit. Even if something goes wrong during coding, you can always recover, its just during flashing that you need to be extra careful.

To answer your prior question, this is the F-series info from the brref.xml file in the mapping directory of psdzdata.
