Interesting. Maybe i'll do the same. I'll have to look into the gateway module. Never heard of those.

Yeah, I am not sure how it all works yet but I wanted to get one before the masses descend. Downside is they aren't allowed to be swapped into a car for NASA 4/5 per the ABS rules, so that puts it on the backburner for me.
I think that Doug has made harnesses for the MK60E5 and I know Andrew Liddell can flash them as he sent me a chassis template worksheet.

Ah awesome. Didn't even realise there was 0-5v outputs for wheel speed. Dont think they are on my diagram. Is that 4 channel? Suppose its an option but much rather have it over CAN. Just makes more sense.... that and the harness is almost complete and i don't want to be adding stuff now haha

notamiata

yes, it's 4 channel

Cool I didn't see those on my diagram. Do you have one to share with them on?

Ah great. I must have missed that! I was using the motorsport diagram I found earlier in the thread. I think I may just run those wires in case I am unable to get the CAN working.

notamiata

it's only 4 wires, and you can run a single 4 wire cable temporarily, which is what i did. I needed a pullup resistor for megasquirt

I've seen quite a few of that era BMW can networks and none of them have the 0x610 message. The closest one is 0x613 which is the cluster. I've also done a 335 swap into an E46 and the ABS definitely did NOT require the stock E46 ECU to send out the wheelspeeds or to request torque intervention during wheelspin.

i've been in the process of switching over from Megasquirt to MaxxECU, so i've been looking more into the MK60 CAN bus communication for wheel speeds. I've been hearing you don't need to do anything other than read the channels. This was first-hand from people who have done it. I will be trying it in the next couple weeks, so i'll report back what i find.

On a side note, i realized that i never calibrated my pressure and yaw sensors, so i decided to give it a try. I did this in INPA, and wow, what a difference. The brakes felt a lot more aggressive, and i had no instances of "ice mode" in situations where i would have had it. Highly recommend it.

Interesting observation on the calibration procedures. I did them with the foxwell hand held just because it was an option. I haven't seen any indication of ice mode in my limited use so maybe that is the difference between the folks who have had issues.

Good luck on the can bus, I have mine wired into the network but haven't messed with getting it communicating. My interim solution is a micro squirt as a can bus remote I/O expander

notamiata

I am currently doing the same thing as you with MS3 and the microsquirt. If you haven't done it recently, update your firmware on megasquirt. They made some changes to the traction control settings and it takes averages of both driven and undriven wheels now. seems to work better.

I did see that added, and I've had some very specific issues with TC response differences turning left to right. Fingers crossed this makes it consistent left to right. I've.got an event with Gridlife at Gingerman in a week, it has several 45-55 mph corners and I have wheel spin issues below 80mph so it should be a good test of the improvements

notamiata

I had the same issue before i went to the 4 channel wheel speed sensors with the io expander. i went to the new firmware as soon as i switched to 4 channel, so i am unsure if it would have had the issue with 4 sensors and the old firmware. I still constantly have to play with the amount of timing retard and richening i have based on track and tire conditions, but it seems fairly consistent left to right now. My car is very wheelspin happy, so it is very noticeable when it isnt working. Most of my usage of TC is in autocross, so it's generally all under 80, and it seems like the TC is much harder to set up for that stuff. On the track, it feels like some sort of black magic. I can mash the gas at exit and it will only kick out a little, then it reels itself right back in with no drama.

I ran the new firmware on the old 2 wheel speed setup and it was still very much left to right dependent. When tuned correctly for one direction it was exactly as you described. Really takes the edge off. Feels a lot like how the MK60 does it's thing while trail braking into the corner, just an invisible safety net to save you from yourself

notamiata

For me, and i assume everyone without a spool, it's because my Tru Trac doesn't work well when the inner rear wheel is off the ground, so when the active sensors are on the outside wheels in the corner, it doesn't know that wheel is just spinning.

notamiata

anyone know if a resistor is needed at the mk60 end of the can bus, assuming it's the last thing on the bus? Or is there one internally?

Which orientation does the acceleration sensor need to be mounted in? from what I can find it needs to be upside down (mounting tabs at the top) with the plug pointing rearward. Is that correct?

notamiata

this is correct

It should measure 60ohm between Can H and L.
