This is stupid..
You hav a non-vtec ecu hooked up to a vtec e head,
ur vx / d15z1 isnt gona run right wita d15b non vtec ecu,
th right ecu (p07) uses 12 valves in low end torque + thn
wen a less extreme vtece kicks in at around 2500 rpms
thn it opens both intake valves. This saves gas and wen done
correctly u can get 50+ mpg wit these motors.
and u need th egr and 5 wire o2 sensor or itll throw codes
and not get as good mpg as its capable of.
Also wen u put vx engine in a car tht didnt come wit it stock
thn its not gona hav all of th 5 wires frm th o2 sensor goin
to th ecu right.
