I was surprised to learn recently that one of the 'modern' ECU's SM4 (I think) does not support sequential injection.
The standard Weber management was formula 1 technology of the day that Keith had fitted to one of his cars.

Until you drive one or map one lol.
The Sm4 is not considered modern now as design over 10years old and does most definitely does do sequential injection.
The Webber l1 to p8 is definitely not modern now and definitely very old hat. Of coarse it will start and run a YB quite well today it can’t possibly match a modern Ecu of today.
