DET3+ Mapping for VTEC

Hi all,
Need some help
Regarding DET3+ mapping
I actually did data gathering and I converted to MAP then i interpolated but i have some concerns
Because while driving with high RPM i can hear some engine knocks
I guess because of the VTEC system on my car
I would like to know if any special wiring for the VTEC or i need to adjust the fuel table

Thank in advance


In my opinion, the optimal solution would be to switch the fuel table when VTEC is activated. However, this will necessitate a two-stage conversion from MAF to MAP: one for when VTEC is not enabled, and another for when VTEC is activated. To switch the tables, you can use a map switch input in conjunction with the VTEC solenoid signal.
