my EFI sensors.

[T77911S]

thought I had a pretty good idea.
I have a knock sensor on #2 and 5.
my head temp sensor is on #1.
all can be accessed by removing the alternator.
I had the heads tapped and put studs in for the knock sensors and#1 tapped for the CHT.

Helps not having those pesky fins in the way, eh? Looks good

What EFI are you using? Is your efi knock model sufficiently sensitive to reliably detect knock in cylinders 1,3,4 & 6?

I suspect Porsche made the knock sensor bridges on 964's and 993's for a reason and didn't just rely on the cam carriers and the crankcase to transmit vibration to the sensors

Neat work BTW!

I am using a MoTec M130 ECU along with 964 knock sensor bridges and the Factory sensor. My system is able to detect knock in individual cylinders quite easily.

I am really impressed with the M130. My race engine gets really great fuel mileage...better than it did previously with 80 less horsepower. The previous ECU I used did not support sequential firing of the fuel injectors while the M130 does. Even at 8000 RPM.
