Default RX-7 550s -Injector on time? What are you using?

DIYPNP base map. Hoping to start tuning on Saturday and looking to get all my settings right.

How do I find the injector on time to use for these puppies? I'm assuming this isn't an unusual setup around here.

Uh oh...15 views and no replies. This is starting to feel like a dumb question.

I'm using 1.2 ms. I haven't done the scatter plot method on my set but I believe that people who did that with the high-imp RX-7 injectors saw non-linear results with the slope indicating anything from 1.0 to 1.5. I had always been using 1.2 anyway, but if you're inclined to mess with it you can read this thread:
