Default I need some cold weather Cranking Pulswidths

I think Brain may have the closest to my set up, injector wise. I found a thread from 07, but I couldn't tell if it was Brain's CPW's or not.

I am selling the car to a gentleman up in the North and, well, it doesn't exactly get below 30* in FL very often.

What I would like to see is some CPW's from a Miata that is close to the Mason Dixon Line, and that is running 460cc RX7 injectors. I could do the math easy enough, which I have done, but still I would like to see some cold weather cranking PW's.

I would greatly appreciate any help with these.

In for answers. Aside from a different turbo, 1.6, and an internal wastegate, we have very similar setups. It's also in the low 30s right now.
