whats worse is when a stand-alone contains features you didn't know would interfere with what you had planned for the engine. The AEM for example has a feature which allows a bad map sensor to jump to an "alpha-N" type of map, where throttle position dictates fuel instead of map pressure. However, this map is also apparently used when you "max the map sensor" which I find inappropriate and annoying. Sometimes I want to run just 1psi over the max of the 2-bar map (~16psi) but I don't want it to jump to some alternative map for that extra 1psi. Instead I want it to ride the 15psi line as if nothing happened. If you arn't away of this... hidden setting... the default will jump to the 7psi line of your fuel map as it passes 15psi into the 16psi region (instead of just sitting on 15psi like you would expect). By default, this is a dangerous setting to hand to somebody in a "plug and play" ecu.

MAP is tuned like any other ecu, generally wideband logs are reviewed and you plug formulas/maths to make it faster if you want. Depends how long you have the vehicle for. The PFC has its own MAP Sensor but you can change the settings (pressure : voltage) to use any MAP you want I suppose.
As far as fail safe, If you are worried about the engine you run a fuel pressure safety switch in any application first and foremost. After that, use the fuel cut limiter in street/daily applications for best results. If you have an expensive engine you also will want an oil pressure data-logger and safety switch for that as well.
