(latest can have 2 types slots, one on SPI2, second on SPI3)

I can build FW without SPI2, but I have no idea, if it works on yours MRE :arrow: :roll:

Re: Proteus - Waterproof, High-feature ECU!

as you say .. You have two identical setups ... but two different fuel pumps ... one is wrong, maybe ... poor condition, different type of DC motor ... (no caps and/or inductor inside, etc) ..and VNLD5090 can't handle this situation ... try to use different type of load (bulb .?? ) on this output ..
