I wish I had a flow chart of the MK60 ABS algorithm. :)
I hate relay's and switches.....I'm considering not installing the Brake Light Switch and the required relay to get the "no brake = gnd" circuitry. (Although mechanically, I could make a custom bracket that activates a switch when the pedal is not pressed, and floats the input when the pedal is pressed, so no relay needed.) I guess leaving the BLS input pin floating, the MK60 sees "brake light on", but 0 pressure from the sensors, and ignores the BLS? Put anther way, maybe the MK60 ignores the BLS until it faults one of the pressure sensors? |

After sitting down and looking at it yesterday, it seems like one way to clean it up a bit would be to use M12 bubble flare dual banjos into the ABS unit with one of the fittings being a M10 bubble that you thread the pressure sensor right into and the other fitting being a m10 inverted for a MC feed line.
edit: accidentally a word Looking in pegasusracing for fittings now! |
This may be the money shot for my setup. Thanks for the idea, headed to the shop to measure a few things!

I hate all the AN3 junctions I have (BMW sensor + prop valve or AiM sensor, front and rear). Looking in pegasusracing for fittings now!

I suspect a number of us are tied to the MK60 due to NASA lol rules

Then I noticed the post above talking about the length of the M10 nuts so it sounds like I'd want to order:
12x Brakequip BQ4511LT 3/16 M10x1.0 long bubble flare tube nuts The flare nuts have different nose shapes because the back side of the DIN/ISO and inverted flare is different (first being flat, second being angled) If using Brakequip nuts for M10x1mm DIN ports and flares the proper part number is BQ72 - it is properly shaped to support DIN flare and should be the correct length too. |
I just looked up a link for you from that site:

Seems you're trying to use inverted flare nuts in the ports of the MK60 (the seats of which are for bubble DIN/ISO flares).

Here's a plan I put together for myself to help make the wiring loom and also to help me troubleshoot in the future, wire colors I made up myself with the wiring I had. I made the complete harness on the bench and then installed in the car.

If the outlet port of your MCs is on top (the way most duals are) and you bolt this banjo there, how are you going to take the air out of the side with the sensor since it is a dead end and no fluid flowing through?!

Yea, I'm a big fan of mounting those (or any) sensor such that air rises to the line. My pump is mounted at an angle, and I think it might all work out. That said, my plumbing is done and leak free (whew) so this would be a change I'd do down the road.
Got a good start on my harness/cable today. Timwrx, thanks for the pdf, I'll be double checking mine against that. https://cimg5.ibsrv.net/gimg/www.mia...f790379550.jpg I'm going to mount a lever switch next to the brake pedal for the BLS input. I have my brake lights activated via an AiM pressure sensor, but a normally closed lever switch should would great for this...I think. |

The BMW unit uses an ISO bubble flare not a DIN flare, the inverted flare nuts work for both bubble and inverted flares.
The DIN/ISO bubble flare has a flat back thus the different shaped nut. BMW use DIN/ISO bubble flare and this is what the BMW flares and their nuts look OEM: https://cimg5.ibsrv.net/gimg/www.mia...6643bcf6d8.png I guess you could get away by using SAE bubble flares, but you'll be off the OEM spec |

Your picture has the name wrong! What it calls ISO bubble flare is a SAE bubble flare (also called British bubble or Girling bubble). The SAE bubble flare has the same back as the SAE double inverted flare and they share the similar nuts.
The DIN/ISO bubble flare has a flat back thus the different shaped nut. BMW use DIN/ISO bubble flare and this is what the BMW flares and their nuts look OEM: I guess you could get away by using SAE bubble flares, but you'll be off the OEM spec |
Do the inputs of the BMW E46 wheel speed sensors have polarity?
That is, the ABS controller pin-out shows "Signal" and "V+" for each of the 4 wheels speed sensors, does that matter? |

Thanks!

Incredible work here guys!
Does anyone have any tips on depinning the large controller plug at all? |
