Hey guys, not sure if its been done before, but is anyone interested in a tutorial how you can tune your own ecu for the Mk5 and Mk4 R32? I've been doing it for a couple of years as a hobby on my MK5. It is quite a bit to write up so I need more than 10 people interested. I'm not a pro at all but with the info and some initial soldering , you will be able to flash new settings, such as cam timing, ignition timing, fueling, turn off cat heating and what ever else you want in about 5 mins at a time.

As far as I can tell the cylinder head, cam bridge, VVT/VVL actuators, and SAI system. the CBRA has a cylinder head that uses two combi valves, and the BUB only has one. CBRA is what came in my US 2008 MK5 R32 and the BUB came in an 07 Audi A3.
Both cars are 32v VR6 with DSG, and Haldex AWD. They also share P/N's for other major parts like block, crank, cams, cam phasers, etc.
For backing up all 3 components use ST10Ripper, I think I posted a link to it some time ago. For this use a plain kline cable, the normally cheap blue ones.No need for the special boot mode, it can work just with ignition on, in the car.
For cloning the backed up files you need to open ecu and put into boot mode. Then use mpps 13 to do the flash and mpc and use the blue cable with some other free software which I now forget to do the eeprom.
Use 2.24 or other newer ones. Patch the MPC and the eeprom so that checksums are not done, then you never need to use the outdated 1.5
But hold on a minute, you are much better off keeping the ecu that came with the new motor! Just edit the eeprom with the cbra vin and immo details. This works if the bub motor is from an r32 with the same type of transmission (manual or dsg).
Quick question on that topic. It seems that the new genius from dimsport can read and writte the flash directly from OBD port, thus without having to pull the ecu out and pulling down to ground the boot pin. Is it possible that boot is acheived internatly by the new genius some how?
Mpps, kess and many others can do it too. It takes over 20 minutes vs 3 minutes, it is a standard built in feature of the ecu software, not the special bootstrap mode that is built into the microprocessor itself.
You cannot clone without opening the box, but you can turn off the immobiliser on the new ecu and change maps without opening it.
Ok so if I get this correctly, you can always read and writte files straight from OBD. The only requirement to open the ecu and put it in boot mode is to copy and paste flash+ immo data. In case I'm working on my own, immo ON, ecu I don't need to put it in boot mode?
If you are working on own ecu, no need to open up ecu for writing or reading flash, but you need to correct checksum and be prepared to have to open up the ecu if the writing process via obd does stuff up! Btw is it mk4 or 5 ?
It is an MK4. I have the checksum add-in on winols. So in a nutshell. If it crashes due to bad checksum, writting in boot mode bypasses the fact that you need to have the correct checksum?
Interesting... if I take for example on EDC controllers the checksum needs to be calculated either by the tool or the software regardless if its BDM or OBD.
So to recap the boot mode is the equivalent of the BDM on EDC controllers in order to do Immo stuff, coding etc..
The mk4 makes it easier as it is c167 based. The mk5 is st10 which is more troublesome. Yes, bootmode is BDM. I recommend obd port flashing for the mk4, especially you don't need too do it many times. 20+ minutes adds up! Just use the winols to correct checksums, although clone tools seems to work fine too! Im not sure if the ecu will be able to reject a bad crc flash on the fly when using obd, but on the second attempt to start the motor up, it will not start if the crc is bad. You may be able to reconnect without boot mode, and flash again. Not sure but I heard its possible.
