Default Converting EMS Basemap 1.6-1.8?

Car is all wired and ready to get timed and fired-up. I have a "professionally tuned" basemap for a 1.6 on a gm 3 bar with gm iat, nissan VTPS, 725cc injectors, and 2860RS.

My car is a 1.8 with RX7 550cc injectors and a 2560R. I know I need to re-scale the injectors, what else should I scrutinize before I try to fire the car?

You'll find that some of the sensors have different outputs and junk. I'd just use a base map for your year of car and then transfer over the ignition and fuel maps.

Thank you. That was the other option I was debating. How hard is it to import the maps? In this scenario, all I should really need to do is scale the AEM base cal for 550s and import the maps.

I was hoping to do it the other way mainly because it should be a full tune. I have no intention of relying on it, I'm taking it to the dyno right away in fact. Thing is - the dyno shop is 150 miles away, so I need it to be half decent to get there.
