In IRC, I had commented about ripping the CCFL lighting out of an LCD display I ordered as a gauge display and either swapping in an LED strip at the exact same location or placing LED lights in the shell of the Toyota gauge cluster. That was met with these useful comments:

6:27 I have done the same, removed the ccfl tubes and inserted some led strips
6:27 my current car has ccfl lighting and with cold weather it is hardly readably for the first 10 minutes
6:28 only to settle at a half-readable state within the first 30 minutes

A few other things arrived in the mail recently:

1. A CANable, which is possibly the cheapest ($25 USD) and tiniest pre-made product I've seen which uses socketCAN. It's based on Eric Everchick's CANtact and is sufficient for bus dumps and monitoring. The following image is linked from capable.io:

2. A sweet 12.3in LCD display. This would be submerged in the gauge display shell and there's clearance in the dash for the exposed corners. The original Tacoma plastic cover will be chopped in favor of a something custom to frame the display dimensions.

After installing the original Pi3, I never was able to resolve issues with the Anker hub while in the vehicle. Removed it this afternoon and have it at the office for testing. Plugged it into a Mac with a flash drive and that much worked fine, so likely a conflict with Raspian.

A working logger would have allowed substantial logging over the past months, something that would be especially useful right now. I've had two instances in the past year where I shut my truck off in the Burger King drive through lane, then attempted to turn it back on about 2 minutes later only to hear the starter going and see no engine activity. Fred's noticed some possible ignition issues in my logs, so I'll want to test warm starts like this while logging. Would suck if my fuel pump's starting to fail again with all this hot weather.

Shortly after the post above, I accidentally destroyed my Pi installation with a failed package update. End result: no modules loading. No USB, no touchscreen, no network, no bluetooth, etc. I was hoping to save it in some manner and still might be able to, but will likely end up rebuilding it was NOOBS lite and transfer over the account and scripts. Not a small amount of time. I really need to be logging right now.

Also not a small amount of time, but requiring less concentration, I bought a Craftsman drill press off Craigslist for $150 with a new belt. Most go for higher and I thought this was a great deal, but it turns out there's some wobble, the ground prong has been knocked off, and the quill won't recoil (and occasionally takes some effort to lower). This unfortunately wasn't so obvious at the time of purchase--seemed like just a little wear at the time. At the very least the drill needs to be cleaned and re-greased, though I plan to replace all the bearings since it's already in pieces. I'll also replace the 1/2in Jacobs chuck with one that goes to 5/8in and hand-tightens.

Throughout the years of driving my truck with FreeEMS, I've only had a few unexpected problems that went beyond normal maintenance issues. I ran the following by Fred first so as not to give the impression that FreeEMS (or my dodgy Jaguar assembly) was the culprit. He provided his thoughts and suggested I ask openly for thoughts, so any and all are welcome.

Quote:
I meant to send this earlier for your thoughts, but I don't think it's FreeEMS or my ECU at fault. I wasn't logging, unfortunately.

Last Thursday I was leaving work. The temperature outside was 106F and the car had been baking in the sun for hours. After leaving the parking lot and getting out on a main road, probably about 3 minutes from start, I was cruising at ~30mph and noticed the speed reducing despite pressure on the gas pedal being consistent. I couldn't get the vehicle to speed up, so pulled into the road center as if to turn onto a side street.

The engine made chugging noises as if it was struggling to operate and I'm not sure that I've heard it make those specific noises before. That is, it sounded different from just dying from fuel starvation. Plenty of vibration. I was able to restart the vehicle easily enough, but the same clunka-chugga type noises and resulting vibration occurred, I couldn't get the car to move more than a couple feet, and it died again. Instinct suggested something with ignition timing based on sound and perhaps the problem you (Ed: Fred observed in previous logs that I had occasional ignition misses) were noticing suddenly became more of an issue.

I was then able to start again and slowly creep into parking lot, cycled the engine again, and everything was fine.

One thing I've noticed lately is that there's a feint whiff of fuel when I'm home and parked in the garage (it subsides after sitting, so
the leak is most obvious when the vehicle has warmed up). Perhaps the heat from the day led to something odd with fuel pressure that day. I'll recheck all my hoses and seals around the tank when time permits and at least try to avoid any fuel leaks. I might also start
budgeting for new coil-on-plug igniters as a maintenance repair (recall that the plastic shrouding on some has mild cracks) and to rule them out.

There's one other issue I ran across twice, both times at the Burger King drive-through and I believe in vastly different temps (very
cold/very hot). I stopped the car after about 10 minutes of driving, then tried to restart and only the starter would sound. No audible
attempt from the engine to do anything. In both cases I had repeatedly pounded the gas pedal and turned the key multiple times and
eventually it would restart normally as if nothing was wrong. Both times I'd say it took about 30 seconds max to go from no-start to
start. I'll test this one out in a similar manner and see if it's easy to reproduce.

I'm going to approach the former as a fuel issue right now and try to get that resolved.

As mentioned above, I'm going to work on the fuel issue and attempt to log a no-start situation if that can be repeated. As for what happened on the road, that might remain a mystery until I get dependable logging going.
