I actually have a piwis 2 but haven't played around with it enough to know what it's fully capable of. That may be the best place for me to start. I appreciate you helping out though!

I'm actually really hopeful that the DC voltmeter idea works out. It seems like all the aftermarket visual knock indicators work on the same principle, it's just about finding the threshold. Interestingly the me 5.2 ecu has an output wire specifically for knock detection! You could literally run a piezo or a light off it and be done. But noooopo they had to do away with that for 7.2

Btw, I lied when I had nothing up my sleeve. All of this is in preparation for eventual Dyno tuning. I still have a lot to work through but I'm pretty sure I've figured out how to control afr input. I need to be able to monitor knock and timing (it would be awesome if I could rig a warning light to let me know when the engine is pulling ignition timing but I haven't figured that one out yet). The final part will be timing control. I wish aem would bring back the fic/6...

Update - oh look, I found one! In case the pic quality is crap, it's$99,999. LMFAO
