Can we route some stuff to unused middle plug pins please? This would allow easier PnP Miata NA6 and make unused pins more useful in general.

GND to bottom of W36
GND to bottom of W35
+5v to bottom of W28
+12v to bottom of W27

This keeps falling through the cracks. I finally remembered to tag it.
178) RESOLVED IN R0.5.5 Update AN input schematic to note "low pass filter knee at 1kHz or 10Hz with 10k series resistor"
179) RESOLVED IN R0.5.5 Update AN input schematic to note "low pass filter knee at 10kHz or 100Hz with 10k series resistor"
180) RESOLVED IN R0.5.5 Update AN input schematic to note "low pass filter knee at 100kHz or 1kHz with 10k series resistor"

Fresh batch of assembled boards has arrived. With two of them producing a bunch of lovely sparks during power supply testing, I am now always wearing safety glasses while doing 12 volts testing or soldering.

Stay safe my friends!

Hello all,
I am running frankenso for 3 weeks. Today i tried an autotune and the engine died. By reflex i did ignition off. The board shut down, ts disconnected. Ignition back on and ts would not reconnect.
I have restarted the ecu and ts. Now i have connection. The engine would not start any more.
Noticed tps died. Adc input zero.
Checked wiring till the ecu and sensor and they seem fine.

Tomorrow i will check pin config and opamps and inputs.

Did somebody had failures like this that adc channel just died? I would try last result to reroute it to another channel.

I have reloaded the msl file so i would presume that pin configs were resent to the controller.
Water temp looked ok so adc is working.

(moved to Frankenso topic since you say Frankenso?)

I am not aware of sudden burn or loss of ADC.

If you assembled the board yourself, identify the problematic channels and redo all the solder joints. I had a similar problem due to poor solder adhesion and cold solders

Also with a multi meter connected to frankenso ground, you could provide a table of measured voltages and frankenso's claimed values. I suspect you'll find Crazy Strikers comment about quality of assembly / cold solder joints is applicable. Is this a DIY board? Pictures of the board might also help identify problems.

Nice authors of ibom tool have made a fix for us and now Frankenso IBOM contains MFG and VEND part numbers - https://rusefi.com/docs/ibom/frankenso_latest.html

Are there any plastic parts in the Frankenso kit that aren't oven temp proof. I assume all the THTs get put on after, but how about the USBs, coin cell holder, etc.

USB and coin cell are probably safe. I've reflowed SMD USB connectors before, and many of them come with a small piece of tape on top so that they can be placed with a pick-n-place machine.

The big harness connector might be safe, but I'm not sure why you'd want to.

oh, that's what it's for! do they need tape for a suction cup to work?

Yep, the pick-n-place machine uses vacuum and a little rubber suction cuppy thing to hold on to components. So anything that doesn't have a relatively uniform flat top needs a piece of tape or something.

Likewise, the vertical USB connectors on the microRusefi board had a little "fake" male USB connector plugged in to them, with a flat top on it so that a pick and place can grab on to it.

I don't think this is for Frankenso, but the brain board. What board is this applicable to?

this is about Frankenso, this is about op-amp channels which could be used when Frankenso has MAX9926

When you get the Frankenso pre made, can you see red dots of glue under the 0805s on the underside. I hear that 0603 and smaller will stay on the underside without glue with a 2 oven process - oven solder bottom side parts and re oven for the top side parts -, due to the solder surface tension, but I'm not sure if I should risk 0805s. Basically there is a lot of 0805s and not much space between the pads for glue. So do I try for glue, or hope they stay attached hanging on the underside without glue during the 2nd oven heat.

I've successfully had 0603 and TSSOP-14 stay on the bottom of a board during a second reflow, while assembling microRusefi boards. I pasted, placed, and reflowed the back, then did the front, with the board propped up on stacks of more PCBs on the sides. Nothing fell off!

I've had 0805, 1206 and some larger chip packages survive a 2nd reflow. I've been amazed a how sticky the solders surface tension is. I was using Kester 256, which is a leaded solder. I do not know if the surface tension is different with different solders. Perhaps different solders would be less sticky if they have a different surface tension. Also what I do know is that is is best to wait until it has had more than enough time to cool down. I've been eager and pulled them to early, which was a catastrophe.

So even a 1206 will hang upside down. I've got enough spares so I might as well run a test to be sure.

Any chance of getting the "frankenso-cache.lib" file, as I'm having that missing part problem in SCH with KC5.

I'm trying to sort out why there are parts on the iBOM but none in the kit, like C103, and if I need it.

From memory I'm fairly sure I've done so8 in the bottom side.

Can you rescue? I recall the cache fine if have as it can be used to avoid the rescue file. Also what file are you looking for? Frankienstien frankenso other?

I found C103(10uF) on page 8 of the SCH PDF, and it kind-of looks necessary in filtering the input 5V to the MAX9926. Luckily I have one here already.

I put several blah.cache.lib files in my repo, Frankenso should be updated some time soon-ish to include this file.

I have questions about troubleshoting Frankenso board. I've one from tindie.
Display on board stop working. Is there way how this display can be enabled/diabled?
Which USB connector is for connecting Tuner Studio?

Please post a picture or record a video since too many different things could be described as "Display on board stop working"
There are no way to disable power to the back light for instance, back light is always on.

Both mini USB on red board and micro USB on green board would connect to Tuner Studio.

Backlight is OK, but seem to be an issue with display initialization. See below:

please understand how little information you provide. what did you do before this happened? have you ever seen blue led on green board blinking? iz blue led blinking now? can you connect with TS? can you connect with rusefi console? this is probably not a screen issue but firmware or configuration damage issue

I'm apologize, Leds are blinking. I've connected throttle body sensor and after few seconds display goes in "two line" mode. Tuner studio is working and throttle position sensor is working in Tuner studio.
Rusefi console is also working.

I understood that problem can be with hardware, dead display or dead gipo on CPU. Or someting in configuration.

Today I'v upload snapshot_20190806_000757_frankenso_na6_rusefi.
