Knock controller test on a Lightning

Mike · 03-04-2008, 12:30 AM

Did you guys do any testing this weekend? Any results?

Mike:

Yes, we installed the system late Saturday afternoon and did some testing. His engine is pretty quiet, didn't have any interference from the rumored "blower whine".

We jumped on the I-5 near his place in Oceanside and made a couple blasts up to 120 mph. Too much traffic and no hills to get any real testing done.

One cylinder shows a little inaudible knock on tip in. Unit detects it no problem.

Minor software issue to tweak, hope to spend more time next weekend.

We routed the main harness and knock sensor cables through the same hole he used for his boost gauge.

The wires are connected at the two large plugs on the passenger's side of the engine bay.

Will just the basic unit indicate knock? or does an extra gauge have to be purchased?

Mike:

All units have a multi-function "Status" LED.

The LED pulses during cranking as each cylinder fires, merging into a solid glow as the engine comes up to idle speed.

The LED turns off as the engine goes above 980 RPM. Above 1750 RPM, the LED will again turn on, glowing in proportion to the amount of knock retard.
