Yes, and modern ECUs with knock sensors will automatically compensate for that. See, this is exactly why car comparisons are frowned upon. There is always an extra level of complexity involved that isn’t accounted for.
I believe 3DS does that (and UFID is also trying), but 3DS mostly uses it as DRM. Again, just like most 2D printer makers.
But still, it is legal (and non-warranty-voiding) if you’re using a cartridge with a cloned chip. The only thing that’s stopping refurb cartridges nowadays is patents on some part of the chip’s encryption or other measures - for example, Canon uses a red led on many of its cartridges to signal the user which one he has to replace, but also uses a light sensor to check that that LED is in fact present and lights up at the right times. Which is patented.
@Thomas_Sanladerer Knock sensors will not so much ‘compensate’ as ‘keep you from blowing up your engine’ – it’s still going to run like crap.
(Unless you have a very non-basic engine with all sorts of things the ECU can control that are not standard issue)
@Jasper_Janssen Lol your wrong on additives as it depends on the valve and valve seat materials.
Knocking is over fueling and also known as pinking.
All vehicles sports cars or otherwise are designed to run on 95 octane. But you are recommended to use premium.
In the US “Regular” is 87 Octane, and “Premium” is 93 or higher.
Knocking is caused by predetonation. the additives in Premium fuel, are intended to lower the flashpoint temperature to alleviate predetonation.
