AiM Dash Display install

So just need to buy Guage S and then upload the code from github? Let me know when you want to sell your old one.

Kinda. The things on GitHub are just example config files. You can write your own and tell it what to do.

For this, you'd want it to poll D bus for the brake pressures and then retransmit over CAN. There's more info on the wiki if you're interested: https://github.com/handmade0octopus/...ameters-config

I'll reach out when I get my second unit. Can also help set everything up. Should be easy enough to test with both units in hand.

It’s been great so far. Easy to setup and configure if you’re used to race studio and status variables/inputs/output configuration.
I’m still running the GM5 and heater core and it has no issues powering all that plus the engine and light related components. It’s also nice having the half bridge outputs to control the wipers.
Only down side was finding out how much current everything in the car draws and realizing I went far too conservative when I built the chassis harness. Suppose it’s better than going the other way.

I just ran the brake pressure signal wires to my AIM PDM32 inputs. It’s a typical 0-5v signal and the scaling is linear. If you want, I can post the sensor scaling.

How do you like the PDM? I've been thinking about one for my other car.

Ah, thats good. I still think going to a 2 would benefit you. Everything you set up with that will directly transfer to a dash. It would be a stepping stone and if you find a used 2 and sell your 1, the price to change won't be much. *That is what I am doing before I go full dash.

Good point. There is a fear aspect to going to the dash or even a Solo 2 because AiM makes nothing easy. At least for me.

I also got the car to a point where I can do a full weekend at the track and no longer want to push it off a cliff afterwards because of issues. So I'm also hesitant to change anything right now...hahaha

At some point, I will go with an AiM dash which should solve this issue. I just need to accomplish a bunch of other things first - still trying to get the car under 2500 lbs which is proving to be quite the challenge.

I don't pull oil PSI since I use an audible alarm - a piezo siren wired to a pressure switch. There is a super load and annoying alarm (at speed w/ a helmet) if the PSI drops below 20.

Convert to a Solo2 DL and then you can add analog inputs. You can then monitor oil pressure and brake pressure... that's what I plan to do, amongst some other components. *Edit, I'm surprised you aren't monitoring oil psi already.

I've installed a couple brake pressure kits to wire into a datalogger and it seems like a solid option for a track car. This will give you the idea to piece your own kit together, https://www.moreheadspeedworks.com/p...-pressure-kit/

Yeah that device should do what you want.

Another option is to wire a Gauge.S in and have it retransmit the pressures over CAN:
- https://shop.sorek.uk/products/gauge...elopment-board
- https://github.com/handmade0octopus/...retransmission
Keep in mind that if you go this route the Gauge.S will essentially be completely useless except for grabbing and retransmitting brake pressures.

The box is more expensive but at least seems to be plug and play. Gauge.S is cheaper but will require more messing around.

Edit: Actually, I have a second Gauge.S coming my way. If you want an extra cheap way to do it, I'll sell you my old one once the new one arrives. Nothing wrong with it, just wanted the newest board revision

Is there a way to pull this data into CAN so I can log with a SoloDL?

The device Heinz linked would pull that data over to CAN, but otherwise you’re on your own.

[bigjae46]

Been experimenting with this so will add one more thing in case it's useful for anyone else.

There is no way to get brake pressure on CAN from the MK60, even after sending the DS2 command in the previous post. There's some references online to brake pressure being available at CAN ID 0x1F8, but it looks like only AWD cars will do this. The DSC module on AWD cars is different to the MK60, so unless you write some custom MK60 firmware, you're stuck with reading the pressures from D bus.

I was also just made aware of this thing: https://www.airventdisplay.no/en/onl...60-detail.html

Seems useful pretty useful.

Okay can confirm that brake pressures are available on D bus (not K bus) if you request them from the MK60. The following DS2 command is what you need to send out:

B8 29 F1 02 21 06 45

You'll get a response with 15 bytes of data. Front brake pressure is 2 bytes long at data offset 6 and rear brake pressure is 2 bytes long at data offset 8.

Here's my Gauge.S showing the pressures:



Cross checked with Inpa and they matched.

Note: Raw pressure values are in kPa and are int16_t not uint16_t (i.e. they're in two's complement)

To access KBUS modules without the cluster, you can add "MODE=KBUS" to your obd.ini file.



I personally would completely dismantle any cheap non M3 cluster with coding index 8, code it to M3, mount it to the backside and then read all the important information via CAN.

Seeing you are German, the M3 kph cluster you can sell afterwards will cross finance a lot of other goodies
