1985 TPI replacing my old batch-fire ECU with a Haltech Elite 750 with 6 injector outputs. I can can leave as batch-fire or set up as semi-sequential by pairing injectors.
I need advice on what cylinders should be paired, and is it necessary to completely rewire the electrical loom for pairing.
Also, will I need to change or add any engine sensors such as a camshaft position sensor or crank position sensor if sequential injection is set up.

 

With only 6 injector drivers, I can't see a good way to pair injectors, and anything you attempt is probably going to be functionally no better than splitting them into two banks,
