heinzboehmer's 2002 Topaz 6MT Coupe

[George Hill]

Trip is push on the LH button, clock is turn on the RH button

[Obioban]

... but how will you reset the trip?

that's a great QoL improvement!

It really is! Feels nice to never have to worry about setting the clock again.

I've configured Gauge.S to send the GPS time out as part of its D/I Bus relay packet. On (electrical) cold start, the BlueBus will wait until it sees a valid time (in reality waiting for the GPS to lock), then set it. Works great!

Slick!! I love it - that's a great QoL improvement!

Milestone!



And of course something had to break. Fortunately it was just the clock adjuster. Instead of doing the sensible thing and fixing the cluster, I decided to write a bit of code and have the car's time auto sync to GPS.

Setting the timezone and DST is kinda clunky with the CD53, but it works just fine. If I'm bored one day, I might add latitude, longitude and date to the D/I Bus relay packet, then spend (probably an unnecessary amount of) time coming up with an algorithm that can efficiently do a lookup on a world timezone map and set everything automatically.

Repos (1, 2) updated with the config and code.

Wait, why am I displaying ambient temp? That's already part of the stock cluster functionality...

I'll fix in a bit.

Edit: Fixed and repos updated.

heinzboehmer wanted to say thanks for providing the final motivation to get a filament 3d printer from reading this thread.

Awesome! Mine has been an awesome tool to have in the garage.

Also, made some UX changes to the extended low OBC display, after actually using it for a while today:

1. Added an "RPM + Overrev" page. Same idea as the "Gear + Overrev" one, but with RPM being displayed instead of gear.
2. Switched over to grab "Oil Temp", "Coolant Temp", "Ambient Temp" and "Vehicle Speed" from Gauge.S. They were previously being grabbed from I bus, but they seem to refresh once every ~2s, which is essentially useless (especially for speed).

BlueBus FW changes on my fork. I also created a new repo to host my Gauge.S configs: https://github.com/heinzboehmer/GaugeSConfigs/

There's also this: https://shop.sorek.uk/products/gauge-s-pod-52mm

But again, not stock looking enough.

I like the idea of 52mm pod even though it is far from stock looking, my vision would to have it display oil pressure, AFR, coolant temp on a cycle and maybe knock or miss fires if detected. It is on the list, but not super high up it.

Someone did something very similar, just not OLED:




But something about it just looks... off. Not the upside down screen, just looks out of place to me for some reason.

That might actually look better on the M3's more yellow cluster. But, yes, sure doesn't look "right" there.

I have some of those 1.54" screens and that was my original thought with Gauge.S - really to have it on the G-plot screen all the time

Mostly I don't need to look at numbers unless I'm datalogging or debugging, but it's fun to see the G-plot and limits. That and digital speed/gear are the only real use cases I'd personally have for it over the ash tray area

[heinzboehmer]

Would be fun to get a red/black OLED designed to be used in the sun that would go in the SMG display area, similar to the e39's Gauge.S

Edit: Just emailed them to see if I could get the ball rolling on that

The 2hz is unfortunate-- otherwise would be fun to do something like oil pressure or AFRs.

The refresh limit is unfortunate indeed. Was really hoping to be able to do something like you describe, but I don't think it'll be very useful at this frequency.

Another thing to note is that while the low OBC display can show four digits, it can only show two sig figs. It accepts a BCD formatted uint8 and a multiplier, so anything above 99 will lose precision fast. Didn't get a video of this but once you get above 1000 RPM (so basically all the time), the display counts up in chunks of 100.

In practice, this means that any number with a decimal point (e.g. AFR) cannot be displayed in a meaningful way. This is exactly why I left battery voltage out, it doesn't seem all that useful at two sig figs and splitting the displayed value up into place values would be very unintuitive to read.

For higher frequency/precision stuff I still have the screen on Gauge.S, which is a good enough compromise.

BlueBus changes uploaded to my fork: https://github.com/heinzboehmer/BlueBusMirrorMemory

The Gauge.S config in https://nam3forum.com/forums/forum/m...515#post360515 seems to be working correctly. Haven't changed anything since.
