Re: Hello from Poland

have you seen the STM32F407ZG board? I do not understand. STM32F407ZG is a chip, not a board. rusEfi is not a highly loaded webserver, we do not benefit from additional RAM allocated on demand :) At the moment we do not have the code to use extra RAM - we need more software developers to implement ...

Where does RusEFi store all the maps?
rusEfi stores all maps in stm32f* own flash

microRusEfi board has an additional external memory chip which we have not started to use yet.

Re: 2004 Mazda MX5 1.8 VVT #50

I believe the unusual proposal is in order to reduce fabrication? If one relocates cable-driven throttle, one needs a matching cable and matching throttle body for the cable. If one adds ETB it's easier to fabricate? this case old throttle body at default location with default cable act mostly like ...

TLE8080 breakout board

TLE8080 could be the basis for nanoRusEfi like needed for scooters and other tiny engines. Something similar to viewtopic.php?f=4&t=1496 but for TLE8080 would help.

Re: microRusEfi

Naive thermal test: Q1 seems to be the hottest component at 20C-25C above ambient. That's with rear side of the shell acting as radiator. Without the rear plate I've seen Q1 at 45C above ambient - 25C+45C=70C on a bench with no load on the MRE. https://youtu.be/QeZ0bujoRjg https://youtu.be/uu4JIkfsXe4

Re: EFI for small engines

You can make microRusEfi cheaper by converting it to use STM32F407VET6 from eBay. I believe there are some main system chips for two cylinder which would be cheaper than TLE8888 we use in microRusEfi.

So go for it!

Re: microRusEfi

+12v into each of the connector +5v lines was a success - MRE has survived.

Wiring GND and +12v was a success - MRE has survived.

Looks like we are ready for 0.3

Re: microRusEfi

Nope, here is how this is connected. The left resistor was added because LED was pretty bright even in OFF state, barely getting brighter in ON mode. Now with the left resistor, I get proper on/off light.

This style of stitching would require drilling and probably dust :( But yes that was considered.
