For those of you following this thread. Ralph is not using the cam sync in the distributor but running the XFI in bank to bank mode. In order to use the SEQ mode he will have to reconnect this and modify the rotor to use 1 tooth only.

Yep and I am up and running and ready for some tuning. I originally did not time my distributor properly so it was probably ,180 out. Thanks for everyone for the help.

You can run it sequentially out of phase. This will allow you to do individual cylinder fuel correction

This is what the manual says for the xfi 2.0.


IMPORTANT NOTE - In switching from SEFI to Bank-to-Bank mode, if the cam sensor is removed, the individual cylinder corrections should be zeroed out. Although individual fuel enrichment will not be operational, individual cylinder timing corrections may still be in effect. However, the cylinders the corrections are applied to will change each time the engine is started as the ECU will no longer know where the firing order begins.

That is also correct. If you decide to swap it to B2B, zero the correction tables out

How does individual cylinder correction properly work out of phase? Why would you want to do that?

The injectors are hard wired to the ECU. So it knows what injector it's firing.
Reason: For individual cylinder fuel correction and better idle control with large injectors.

So when you say out of phase I'm assuming you mean the injector timing for a particular cylinder can be 1 of 6 possibilities.
