We would like to see your 2ZZ install… a log of that would be pretty interesting too.Post a log sometime, I would like to see the difference in the 500 and my 2ZZ

Will you be pinning that knock sensor into the EMU?I haven't been around much, since I am now back at school, but I figured id stop by to give some updates.
The Abarth is running really well nowadays. I am finally getting the tune dialed in, and I gotta say, hearing the FIRE engine at 7500rpm has given me a new perspective on it. I have pushed the boost as high as 20lbs - far from the nearly 30 it was at before, but I am taking it easy as knock control is crucial for such high cylinder pressures. Despite having setup a seemingly pretty decent knock detection strategy in the ecu, I do not have an OEM level of confidence in it.
As such, before pushing the engine further, I am going to explore options to implement ion sensing knock detection - a process which uses special ignition coils and some light processing as a means to determine cylinder pressures (in real time) simply by applying a voltage across a standard spark plug. We'll see how far I get with that process, but it would be quite cool if I can get it working reliably.
This is akin to Saab’s Trionic system I presume?I haven't been around much, since I am now back at school, but I figured id stop by to give some updates.

Precisely the concept and perhaps even the implementation.This is akin to Saab’s Trionic system I presume?
Through some translation board, that's the hope, since they seemingly have no interest in supporting external knock detection devices. So I'll add my own support...a common theme with my projects at this point.Will you be pinning that knock sensor into the EMU?
That would be really, really neat. I didn't realize there were companies trying to bring it to the aftermarket already.Just about the time COVID hit there were a couple of companies developing ionic knock sensing systems for the aftermarket. The hope was to produce some sort of fairly universal system that could be tuned to use on many different applications. However at that time they only had preliminary designs more directed at common engines (e.g. the GM LS), and they were incredibly expensive. Due to COVID their progress was delayed and the trade shows that included those companies were put on hold. So I do not know what the current status is for it. Hopefully the upcoming show season will be more 'normal' and I may see some of the latest developments with this technology.
