Have been looking at various options on monitoring what's happening with the Zeds power plant and how to best protect it from any potential problems. Has anyone used these gauges from AEM? Not only can they monitor more than one item at a time, ie can have boost and AFR on 1 gauge, as well as log 3hours of data, but they can and this is the bit that caught my eye

The gauge includes a low side output for triggering a failsafe strategy in the event AFR falls outside of the operating window (example strategies below), and an RPM input to log RPM for tuning purposes.

 

Decent explanation of how/what they do

 

Seems like reading this it would be relative simple to wire in a relay to trigger an interruption to the boost controller or cut the ECU momentarily. Interesting read below

Your guys thoughts and comments welcome as usual

Anyone?

Bump as I am looking at this atm.

Tom, I have bought mine, although not in the car yet (as Jimmis still finishing her off). After looking at was is available its the best solution IMO for OEM/Nistune mapped cars. Next step up would be something like Haltech Platinum Pro Plug in Solutions and wire in additional failsafe features to fully protect your engine build.

Thats good and ok .but my question is can you have it set up so you get an alarm first if you get close to the perameter limits before shutting down the ecu and your engine.cas its one thing killing your engin but if i was razing around the bypass then this thing cut out my engine. Then im goin to be in trouble doing whatever speed and loosing all power and steering.

Once the gauges are installed, you connect your laptop with the AEM software on it to the gauges and set your own parameters base on how the car is running. You can set the tolerance as close to the engines AFR as you like. If you look at the first link in my first post I think it shows how his is set. Basically the failsafe doesn't kill the engine/ECU you can set it to interrupt the boost control, thus having no boost just low power so your PAS and everything else will still be work.

Ok nice one.

not quite no boost, it will be base boost ...
