Default Chipping a p28 to use secondaries?

The wiki page on pgmfi is not working and I can't find anywhere archived on here how to do it.

Can anyone shed some light on how I can modify the p28 ecu to run the secondaries on my h22? I don't want to zip tie them open or run additional wires either.

it can be done you have to run the wires from the nitrous ports on the hondata and use hondata to open and close them through the nitrous feature.

I remember someone saying to use the P28 auto ECU to control the secondaries.
