More really cool electronic nerd stuff from USB data logger to USB programmer? Install in OBDII system? Also led lights that could be used in USB cable for connections? Look through the products link at top of page.

with a bandpass filter installed, i have to wonder how useful that DIY knock detector would be if connected to a PCM...

it dosen't look any more complicated than a DIY aldl cable, but I don't see a schematic on the site

here is another good way of displaying knock if you can get a gm knock filter board off a memcal to suit your engine bore size pretty easy circuit build for DIY
