After many moons I finally have my supercharger kit for my car, the kit is 2nd hand and was shipped to me so I dont have the tune that came with the kit new.

I would appreciate any input on what I would need to do tuning wise to safely run the setup?

My initial ideas are

adjust TEMIN, KRKTE, TVUB for the injectors
increase KFMLDMX for more airflow
reduce KFZW/2

then I will play with fueling once I am able to log.

I'd add some fuel via LAMFA before running, it. The file I've looked at is set @ 1. Figure lower it under high load/rpm to prevent from going lean.

There are maps that govern changeover. I have no idea what they look like, but I'd love to see an example.

Search the FR for sumode.

My understnading is that they are the conditions that dictate when the intake changeover occurs. I would love to see an example, I'm sure I could find it in my file, I just have no idea where to go from here.

What dark magic is that, and why was I not made aware of its presence?
