lol I should build an Arduino to sense WOT and automatically press the ESP button...  Kidding...  So the S4 Wiki procedure will disable both ESP and ABS brake Bias or will it just permanently disable the ESP keeping Brake bias? (no mention in WIKI about the bias) :S |

The only thing it does is cripple the ASR... which means ESP, EDL, etc are all still active, and there might be very bad side effects if the ECU doesn't do what the ABS/ESP controller expects it to do. Modify at your own peril. lol I should build an Arduino to sense WOT and automatically press the ESP button... Kidding... If I'm honest, that is a perfectly good solution |

haha I already have an arduino running behind the deck to fool the deck into thinking it has a Cd Changer.. (Wired in a Bluetooth audio module and added an IPOD connector to give me an Aux input controlling the ipod via serial output assigned to the deck buttons Only used like 3 outputs/inputs so plenty spare ones to add ESP auto off, idea planted.. |

Keep us updated! I definitely think it is a fine idea. You'll probably want some way for the arduino to know what the "current" state of ESP is.. im pretty sure the button is a single momentary switch that toggles the state (internally) in the ABS/ESP controller; I don't think it is a on/off thing (from an electrical perspective). |

If you do, please publish the sketch.

All it would take is 3 wires... 2 inputs, one output to pulse ESP button.. Can solder one to the dash cluster and use an unused pin on the cluster harness to pickup the LED (should be around 2volts...) 2nd one is pickup the 5v signal from the pedal potentiometer. both can be fed right into an arduino... Figured out that pin 32 on the cluster on blue harness goes negative when ESP is OFF.. enabling pullup on arduino should give me ESP status.. now I think for the sketch, if it senses a quick throttle change then disable ESP otherwise turn ESP back on, or should it just be when it gets close to the WOT point? hmmm.... project in motion.. Another Idea... Read over in the VW forums that simply unplugging the YAW sensor does the trick as well (disables ESP but keeps ABS).. Could we just put an extra toggle switch on the dash to enable/disable the system? Might be easier than arduino route.. Thoughts..? |

That might be worth pursuing, tbh all the asr has done so far is piss me off, so I'd like to disable it permenently.

I just yesterday tuned an 01 allroad with 551K, made a file from scratch on the spot... Had no issues with ASR/ESP.
Most of the M-box lines up pretty good, some maps you will need to edit even for STG1 will have to be aligned properly as they are off, so most importantly you need to makes sure all the maps you're editing are defined correctly BEFORE actually editing them.
Then you need to know what changes to make and why you're making them. Stop using the flyboy/community thread, it's a waste of time and you're not learning anything if you're just going to copy and paste everything over.

I think the vehicle has to be stationary to enable/disable ESP Read over in the VW forums that simply unplugging the YAW sensor does the trick as well (disables ESP but keeps ABS)..

I'm not so sure this works properly. What somebody REALLY needs to do is to read/write the ABS controller |

I'd settle for being able to reverse engineer it so at least we know what does what (disconnect yaw controller, pull fuse 42, etc). |

Still learning all of this, I do get the basic idea behind changing the various parameters. I was hoping for more of a proof of concept (Converting M /L to a K box from scratch and making sure it will run properly with a slightly modded bin. So I am running a A6 Q-box with a Allroad K Bin ecu that was converted from the M/L box principle... Lots of variables :S Looked over my K-bin def and can't spot anything wrong. Kinda stumped.... Any way you would be willing to share your modded Kbin for HEX comparison? (Stock one runs ok with the ESP off). |

How were you able to read the module? through the K-Bus or reading the chip directly? |

There is a ton of software for BMW's that read/write raw hex. I used BMW scanner 1.4

You're going at this all wrong... you shouldn't "convert" anything from anything else. You should solely be defining the K box correctly (like I said most of the M-box lines up pretty good). Then you should modify only what you need for what you want to do. Ignore/forget almost everything you've read in the community project in terms of actual changes/numbers they don't apply here or anywhere really. The K box (possibly from being an automatic ECU) already has more than enough load request in IRL so for a basic stage 1 you don't need to change anything there. IOP needs a little attention, and then you will need to take care of the load limiters, timing maps, fuel, etc. Again, you're over thinking this completely. Define the file, and look at each map you need to adjust. If you can understand the stock maps you will certainly see that you will have to do less changes than you think. |
