I have a tech training class coming up on feb 21st. the teacher is a really smart guy ive been to his training before. i scoffed pretty darn hard at the course description considering honda accomplished this 20 years ago. heres the course description.
"VVT (variable valve timing) - Meeting the 54.5 mpg car is taking shape with 2017-2025 C.A.F.E standards now in place. Car manufacturers are constantly looking for ways to improve engine efficiency, lower emissions, and lowering fuel consumption across all platforms. This seminar will discuss VVT, one of the technologies manufacturers are utilizing to achieve all of the above.
-how vvt works to improve emissions
-discuss the various components of vvt
-explain methods of vvt operation
-discuss diagnostic service methods with a scope/scan tool
-explain the importance of maintenance to safegaurd oem warranties"
im VERY curious to see if the vx (d15z1) is going to come up in the discussion.
in response to your question, the above is an indication that more lean burn engines might be in the making in cars to come. but for now i dont know of any vvt engines that have the capabilities that the d15z1 does. regular honda vtec engines (d16z6,d16y8)usually engage at much higher rpms (4500+) an ecomodder wont get close to that rpm so vtec wont even be used
