And the L15B1 is only a good engine on paper. It's about 5hp down on the R18 so it's fast. But the carbon build-up is very bad even by DI standards. Servicing that engine is a nightmare. At least in China it's the first PR disaster that caused Honda sales to plunge, though quickly became overshadowed by the oil dilution issue on the L15B7. The R18 despite being an outdated engine from mid 2000s, is very reliable and cheap to maintain.
Seriously, any DI engine without complementing port injection should be a big red flag. Toyota did their experiment in the late 90s (3S-FSE/1JZ-FSE with 1st gen D-4) and it was a limited-scale disaster. 3S-FSE is very rare in the used market because they have mostly disintegrated. So they got the homework done and introduced self-cleaning D-4S. Mazda and VW also got it right.
The whole L15B series (NA and Turbocharged) is becoming a failed 'Earth Dream'. It only ruined their reputation in China for the time being, but it's a huge ticking time bomb that will detonate sooner if american auto press could stop, forgive my foul language, licking Honda's butt.
I have one phrase for the Honda fanboys, that is "keep on dreaming".
