Service call speeds

There's no way to specifically slow down the calls of a specific service itself as such, but you can go into the options of a dispatch centre and disable it from spawning calls in entirely. If you're building up a new area for example and you don't want it to generate any calls yet, you can disable it so it won't spawn any new calls at any of the stations within that dispatch centre.

Alternatively, you can put stations for a service you do not want to spawn in a disabled dispatch centre, thus spawning only the active stations.

I have 6 dispatch centres broken into Fire / Paramedic / Police, so I can just get Fire calls and still have all the support assets, from Medical and Police. So I turn off ambo and Police

Thanks guys. This is what I've decided to do and just run ambo. Still a shame because it limits the type of calls like when they're generated by police but require ambo etc. but at least Im able to actually play without being overrun by fire calls

You can add a small amount of police stations to the active dispatch centre, which should begin to balance out the calls a bit better.

It'll be a lot of trial and error however.
