Would anyone happen to know...

Is the wiring for the knock sensors used in the Mach 1 or GT's also in our wiring harness? Or are the wires not there at all?

In order to run knock sensors with the MS3 you have to use the pins in the main plug. If the wires are physically in the harness then cool. If not I'll be skipping that plan.

I'm sure they're not as I've had my harness off and there are no spare plugs. Shouldn't be to bad to add a couple wires.

I was hoping the wires were at least in the harness from the ECU to the plugs under the hood. Oh well.

If anyone knows it'll be @MalcolmV8

Just run that vampire system for knocking.

I've got a brand new vampire and I think I'm going to run in in parallel to the Holley HP system. I really like the vampire system. This would be a good option for you Slo, it's not cheap, but sure seems like affordable protection.

kinda hard to justify another ~$500 when he already has the standalone.

i thought with the MS3 pro you could get knock sensors and run em as some sort of accessory

In for the knowledge. In the same dilemma.

Does the MS3 retard timing in each cylinder and advance it automatically to find the best timing that doesn't knock? I guess I'm asking how the MS3 uses the knock data/

Here is wiring diagram for Mach

Here is connection c1222

I would also think these are not there on cobra.
C1045 is full which I’m assuming is same as c1222
If those pins are open I would assume you can run new wires to pcm

From my brief conversation with Ed and the screenshots he had posted yes it will do individual cylinders and retard/advance timing like the J&S

Thanks for the diagrams hotcobra. Hopefully this weekend I'll have time to poke around.

I haven't delved too far into this yet. I haven't had the chance. Right now I just wanted to see about running the wires because the ECU is pulled for the reverse lockout update.

What I got from Matt is "The MS3Pro PNP uses the pins on the 104 pin connector that a Mustang GT would use - pin 57 for knock sensor 1 and pin 102 for knock sensor 2." Hence the reason for looking for the wires or the room in the plugs.

From my understanding I can select how aggressive the timing is pulled and added. What temperature ranges to worry about pulling timing. I can have the ECU ignore the knock sensors at certain loads. You can also chose to run either a wideband or narrowband sensor.

The Vampire system is nice. It was on my list of things to get before. But I think if I can figure this part of the stand alone out it'll be more than enough for me.

It's not in the factory harness. I just ran some wires manually for it.

You can configure it pull some timing based on detecting knock. You can configure it to detect on a per cylinder bases or as a whole and you can also independently configure it to pull timing on a per cylinder basis.
It does not add timing above what your tune has but it will advance timing back to the original value prior to pulling timing based on what you put in there.

For those looking for a Vampire I can help with those.

Just load up Tuner Studio and go to Ignition Settings and then Knock Sensor Settings. You can see all the options right there.

I guess the follow up would be is these are the right pins?


Did you use the Mach 1 sensors Malcolm?

No I used Bosch broad range sensors. You can use online calculators to figure out what frequency your engine would detonate or ping at. The main factor been cylinder bore diameter. Once you have a frequency you can pick a very specific sensor. The Vampire uses a broad range sensor as well. Meaning it responses to a wider frequency range. So I opted to do the same. I have not put it through extensive testing. My car has been a dedicated E85 car in the past but I've started using 93 & torco so the knock sensors are suddenly of some importance.

Thats why I'm looking to go down this path. The engine will be spending some time running 91 so I want the extra measure of safety.
