Re: Hellen81 PnP for 81-pin M7.9.7/ME7.9.7/ME7.8.8/Yanvar7.2/Micas10.3

what sort of modifications are these? btw, what's the ballpark estimate for its manufacturing costs? (jlcpcb?)

Re: R42 Board, for V8 engines.

I believe, it's the matter of your preferences. If you need a second ETB, and the firmware supports it, go this way. If you need extra can-bus port (for can-based o2 sensors?) - sacrifice your second ETB (or, better, leave it as an onboard pins/connector). Even if it is not implemented in actual fir...

Re: Nissan on Frankenso #47

this looks like your contrast level is too high. i had a similar problem in a different setup. if I recall it correctly, you need to play with voltage on the contrast pin of that lcd module (v0) - is it also connected to frankenso?

I thought that GD was a full-cycle manufacturer. Do they source wafers from some other companies? People say, this crisis will last for at least a year. Changing a package in the PCB probably takes a few hours. If you are switching to a different package within the same MCU, probably there won't be ...

GD32 version of Wideband Controller

(Fork of https://rusefi.com/forum/viewtopic.php?f=4&t=1856 thread)

considering this ongoing crisis, why not GD32?
GD32F190 is a 5-V series.

Will it be just one WBO (considering initial notion of 8 cylinders, which probably implies two banks of cylinders, hence, two WBO sensors)?

Re: gy6 150 MRE

Где-то попадался аппноут про то, какой размер должен быть у зуба относительно сердечника датчика. Я бы смотрел сигнал осциллографом, прежде, чем делать выводы. Ну и попробовал бы повернуть датчик по оси.
