Ive searched, and apparently most people call "tuning" these engines bolting on parts. I am finding very little info on actually tuning the 7m as far as knock goes. Whats everyones tuning strategy that isnt on a standalone? Is there a way to tell when the engine is detecting knock from the knock sensors? I have seen other cars where you can do some sort of knock light, but I know the piezoelectric KS on our cars are very sensitive, and it seems ridiculous to get those microphone/headphone setups when we already have KS on the engine. Thanks!

You need operational knock sensors, and if using a standalone the Software must be able to detect knock, if not you need a separate knock box and someone that knows how to make it work. For the 7m the ECU and proper functioning sensors, and solid working wiring is all that there is. I think waaaaaay back someone may have done something to display knock separately for the stock ECU. Anything other than this I guess would be with a good dyno tuning session. This is all based my understanding of it anyone more versed on this please chime in.
You can do it with my daughterboard for the stock ecu. Unfortunately, I haven't got my act together and made them available to the community yet.

I've been running a knock gauge for a grand national for the last four or five years, running with a ESC from a grand national to convert the signal....
This is the gauge I have been using:

The TCCS knock sensor when it detects knock will react and retard timing on the next ignition event. It is very good. It also learns what knock retard works best for different conditions and applies that immediately. That's one reason why the piggybacks don't blow up motors.
