Did my ECM mod. I opted to drill through the plastic vent insert instead for the wires. I also attached the resistor to the "ground" pad. Its in series with the switch, the circuit doesn't care. It was easier and cleaner that way.

 

The mod looks great it should do the trick!
Do you have galletto 1260 to try it? BTW Get both galletto and mpps v13. only mpps does the imbedded 'flash' (MCP) for advanced coding later on. Also get a blue Kline cable.
Test 1 is downloading the flash and uploading it back so give that a go. Then, I will show you how back up MCP and eeprom before you do anything.
I highly recommend you put the original CE code in the box instead of the KR, unless you have the A2L file on hand. Logging with vcds is not very good, R32logger is best but needs the A2L, which is available for CE. I had KG and for the same reason put CE.

 

As you guys properly understand all the ecu witchcraft, what exactly happens if I delete my SAI pump and associated nonsense and how can I deal with what I expect will be a warning light and error code telling me that there is insufficient air in the exhaust on warm-up

 

You'll just have a CEL until you get it programmed out. Unless your having an issue I'd just leave it alone.

 

Righto. Thank you . No issue . Just trying to simplify and tidy my engine bay and thought that removing it and it’s pipework would help access etc. I have the blanking plate and water take-off adaptor for the head .

 

Thanks mate. I haven't bought any of the cabling yet. I was focusing on getting the car done. I will be buying them shortly. I opted for the surface mount resistor because it made the mod very low profile and we had them at work. All I had to do was get one off the shelf.

 

Hello,

Thanks for all the info @R32Drongo!

I just put a BUB engine into my US market R32 that has a CBRA engine, and now I want code out the SAI system in my ECU. I have the ECU for the BUB engine available so my plan to start is to Clone the files from the CBRA ECU to the BUB ECU, then work on messing with the extra ECU to try and get this to work.

It seems like I could do the cloning part with the mpps v13 cable and winOLS, does that sounds right? I'd like to keep the original ECU stock, and then I'm happy to modify the cloned ECU.

Finally, do you or someone else by chance have the winols 1.5 installation files still? The links in this thread are all dead.

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).

 

What's the difference between BUB and CBRA?

 

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.

 

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.
