Wideband AFR tuning help.

My 2 cents...

Disconnect the secondaries and wire them shut. Tune the primary side. Once you get that sorted out, then go to the secondaries.

Check to make sure the transfer slot in the secondary is properly positioned at idle.

The primaries are pretty dialed in, and the transfer slots are good otherwise
the idle screws would do nothing for me.

I'll have some final tweaking to do next week when I get my performance
disty and ignition installed.

Widebands are very cool.
