Tuning tonight for meth. I have a knock sensor on the car but I don't trust it and I can't monitor it's feedback. So I've decided to go the Det Can route.
Detonation Cans are used to listen to the physical knock of an engine. Known to be extremely reliable and it's been said that knock sensors will almost never beat the human ear when it comes to knock detection. You can make your own very easily and the performance is incredible.
Required:
- Ear protection headphones
- Copper pipe
- PVC air compressor hose
I ended up spending around 40 bucks but you can do it cheaper. I started with the copper pipe, the idea is to attach one end to the engine block somewhere and the other to the air compressor hose. I flattened the end with a hammer and made a couple of folds to drill through.
Then you've got to run the other end into the headset. My headset was ABS plastic and had a foam insert that was easy to remove. I drilled to a slightly smaller size than my air line fitting and it threaded into the plastic.
How cool will I look when I'm tuning?!
The other end is attached to the engine.
They worked great! You can hear the engine internals extremely well. It was too hot for my taste last night so I decided to push the project off to another day but I did advance the timing under boost by 2 degrees without hearing any knock so that's promising. Bring on the power.

Well I took a buddy of mine to the airport on Sunday and she didn't make it home.. I was cruising at about 70 and the bottom end took a ----. Blew something right through my oil pan. I pulled off and called a tow truck.
It wasn't tuned for the meth yet but I had recently added more fuel under the high boost areas. The cause of the failure is likely just the limitations of the stock block. Most people don't make this much power on a stock block and it lasts them long. I had a safe tune with no knock and strong fuel, it was just too much boost for the little 1.8.
So I sit, listen to some good jams and wait for a tow truck.
I was waiting for this day, and I thank the little bitch for making it through most of the summer, providing me with good times. Forged internals, stand alone ECU and about 22 LBS of boost will do me well for next summer.
