Default Knock controller test on a Lightning

We are still looking for a "test ride" in a Lightning in the SoCal area to evaluate the knock signal.

The "test ride" will require a temporary install of our system, then make a few mild 60 mph to 80 mph passes on the freeway. The system can only retard, so these passes will be even safer than running without the unit.

To install, no wires are cut, though eight control wires from the unit must be connected to the coils. Also, 12v and ground, and a knock signal.

The connections to the coil signals are made with wire splices, and a tube of silicone jelly is included in the kit to prevent corrosion.

We have knock sensor adapter bolts that replace a motor mount bolt, making it easy to mount a sensor. If we have time to play, we may try to find the stock sensor cable and look at that signal as well.

If anyone in SoCal is willing to participate, we will extend dealer pricing if you decide to order within one year.

Please contact me if you can participate in the test.

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.

Jonny glad to hear you got some testing done and it sounds very promising.

I dont know if I missed it or not but do you have any pics of the unit installed?

Drat, looks like I deleted them.

Not much to see, though. We temporarily stuck the unit in the console tray, then routed the harness cables through an existing grommet in the firewall, where Stew ran the line for his boost gauge.

The knock sensor cable runs up to the front of the driver's side cylinder head, where the Bosch sensor is mounted on an unused 8mm stud.

The main cable is routed behind a cover at the top of the firewall, then over to the connector area near the battery.

Stew had the manuals showing the wire colors for the eight coil wires. Four are in one connector, four in the other.

The light was fading on us so we used a flashlight, but it changed the colors of the wires, and I made a couple of boo boos. Good thing I brought extra Vampire taps.

Yes, it's so promising Stew won't give it back. Systems have been shipping since last June. These software improvements are going into all versions.
