I have decided to open this thread, because I haven't found answers and people, who have successfully installed and tuned the daughterboard on the sr16ve sr20ve ecu.
I want to share my expirience and to find answers for my questions.

As for me and my bro
we have installed the db on the sr16ve ecu.

tuned the fuel and ignition maps
changed rev limit.
changed the vq and the maf.

but still no idea,
why the vvl does not work?
why the ecu gives the 54 error (knock sensor error)?

our current setup is a
jn15 nissan pulsar vz-r
sr20ve engine
sr16ve n1 camshafts
bc s/r

now it rews 9k and pulls. but still vvl does not work and we have to engage the vvl manual.

Has anyone got a stock or modified bin file for sr20ve with n1 camshafts? Doesn't matter what Maf/ecu just want to load up and compare timing/fuel maps. Everything else (vvl points/idle/injectors etc etc) has all been tuned

i have the tuned maps
