To be fair there are probably a ton of people that paid big bucks for features they'll never use.
Keep it simple.

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.

PowerFC doesn't have any failsafes. It tells the engine to run in the manner it's programed. It doesn't natively support any sort of failsafe that will cut power to the engine.

So now you're having to invest in additional loggers and controllers to have any sort of failsafe functionality. Now the cost is going up!


Infinity supports a failsafe for any parameter it reads if you want there to be a failsafe on it. I've got my sr20 Infinity setup with wideband afr, fuel pressure, oil pressure, boost, water temp, oil temp and ethanol content, all going directly to the ecu itself. If I set a max or minimum parameter I want for any of these the computer can trigger a fail safe.
I've basically got the Infinity set up to a point where I couldn't blow up my sr20 if I tried, aside from an all out catastrophic component failure.
