Re: Frankenso - ECU shield compatible with OEM case / official

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.

Re: Frankenso - ECU shield compatible with OEM case / official

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,...

Re: Frankenso - ECU shield compatible with OEM case / official

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 ...

Re: Frankenso - ECU shield compatible with OEM case / official

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.

Re: Snap on programming header like the OEM's do

If it's that 6 pin header row in the middle of the Frankenso, it's going to have to be a robust 3D print to clamp 80mm away on it's own. One of those cheap plastic clamps in my video with more reach would make it easier. https://rusefi.com/images/Frankenso/frankenso_0_5_assembled_as_recieved_front.j...

Re: Snap on programming header like the OEM's do

Yeah I've only seen bad 3D prints when they were done wrong, like the high temp filaments, ie: ABS etc, delaminate if not done in an enclosed printer that can keep it hot. I'm not really sure what configuration you want, but I was thinking of just pushing the pins into the female IDC connector of th...

Re: Snap on programming header like the OEM's do

Seams like they do make a 0.5mm pogo, so I suppose you could just slide it in a female header if that is what is on the programmer. Other wise it's a PCB breakout with pogo on one end and the IDE connector on the other. 0.5mm and 0.68mm pogos. https://www.ebay.com.au/itm/100-Pcs-Spring-Test-Probe-Po...

Re: Snap on programming header like the OEM's do

If it's low volume it shouldn't be that hard to 3D print, with some tweaks. ;) I printed this with 1.4mm holes but had to drill them to 1.5mm, which might be too lose. Maybe with some tweaking you could a straight 3D print, and push the pogo in with a soldering iron so the plastic melts a bit and gl...

Re: Snap on programming header like the OEM's do

I fear 3D printed stuff likes to break when flexed. The layers tend to shear. That's only if you are doing to wrong. Like if you print with ABS on a non enclosed printer it can de-laminate. You can increase the number of perimeters, go full solid infill, decrease layer hight so each layer if squash...

Re: Wave strength in racing engines

My memory isn't great after 15 years, and yes now I remember a spacer.

I remember his 1st EMC engine had a piston that stuck out the bore ½" and had a spacer, but the rings were ½" down the piston so he could run it in detonation and it wouldn't break.

Can you run the internal STIM with the wire jumpers PC6 to PD1 and PA5 to PD2 and the console, while communicating with TS. It looks like if you change the engine setting, ie trigger pattern, the STM32 outputs STIM pulses for that trigger pattern. At the bottom of - https://rusefi.com/wiki/index.php...

I was looking at some old clips and TS used to load to 26% even before I installed telnet in my Win7. Do we still actually need telnet at all, because it seams to do the same thing with and without telnet.
