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

Hello,

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.
