Re: ETB or 36/1 performance issue?

Not that I know anything about it, but does it have a variable ratio activation table, ie, 0-50% on the pedal is 1:1, but 50-100 is 4:1. I know it was common in Supercars, but they did it mechanically with changing rate pulleys. I don't even know about the sensors or actuators, but is there a mech r...

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

I was just thinking that the pad is 1.4mm, and a 1206 is 1.5mm, so I thought it would be wise to link them to the 0.070" pins on the Denso connector. If it does 2 High-Z with a single 0805 it's probably not necessary. 8-)

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.

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

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 ...

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

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...
