Every book I've read says that there is a Knock Sensor Output (+ pin 46, Sig pin 23) on all EEC-IV Ranger computers. If you EEC-V guys that have a knock sensor, can let me know what years they are, and where they are located, it will help our cause a lot!

The pin out for the knock sensor on the 02' Ranger's is

Pin 57 signal return - Yellow/Red - circuit # 310

Pin 32 Vref - Yellow - circuit #20

Yep, that is EEC-V, the pins I list are EEC-IV only.

On the 93 Ranger EVTM pin 23 isn't used on ANY Ranger engines and pin 46 is the signal return for more then just one sensor.

On the 94 it's the same in the Ranger.

In 94 it's the same on the 5.0 Mustang, which was EEC4.

The V6 in 94 was EEC5 and pin 23 goes to the Ignition Module and pin 46 I couldn't find listed but there wasn't a knock sensor on it either.

You said EEC4 and 5 ;)

Noted, and corrected.
That is just my point, Pin 23 is not used. It is blank. What is stopping me from putting a pin there and wiring it to a sensor, then attaching the other side to VREF (+) on pin 46?
Bingo, a KS circuit that the ECU SHOULD recognize.

Now I'm not a chip tuner by any means but I THINK if the computer isn't set up nor programmed for the sensor then I wouldn't think it would accept or use a new one. Kinda like adding extra injector pins to a V6 harness to make it a V8. Now this is all my thoughts, I'd contact a chip tuning company to verify this. If it does work then please let me know, I'm gonna add one to my 99', ahahah.

Doug904: Now I'm not a chip tuner by any means...
Nor am I, but, from what I've seen and read, the programmers are typical: Lazy. Not trying to get anyone's feathers ruffled, but many items of code are left in tact, even if they are not used. Why have a computer that needs to be hardwired differently for each configuration? It is far easier to hardwire them all the same for worst case (V-10, multiple sensors w/ A/C) and flash the ECU with just what it needs to run.
While you can't add two injectors to the V-6 harness, you can have the chip reflashed/burned to read 8cyl w/increased displacement and make two new injector runs from the ECU. Not something I would look forward to, but it sure beats a custom harness!
My thoughts on the KS are simple: the KS is (at the risk of oversimplification) a band pass filter. Only frequecies within it's range (some cars have multiple sensors detecting multiple frequencies paralleled on the same line) allow for an output (sensed on pin 23), that tell the ECU to back off on the timing. No input on pin 23, no retard. Why go through the effort of deleating a line of code that will not effect the performance/operation of a vehicle? So...
Once the Ranger is back up, I'm going to add a sensor wired to the ECU and test it IAW the Ford Manual (Idle engine and smack the block with a wrench while watching the timing light :eek: ).
If it works, I see some MAJOR possibilites...

I say run with it.

I think the older taurus had a KS. I bought a 3.0 from a taurus at a nearby junkyard. It had something threaded into one of the lower bolt holes that could have been a KS. The hole had no coolant, or oil passages running near it so I'm not sure what else it could have been. I'll check my EEC manual and see if taurus have knock sensors. I definetly would like to try this myself.

What I found is that the tauruses with a MAF (91?-UP) don't have a KS. But the older ones with MAP (88-90?)have a knock sensor. But the knock sensor input to the EEC is with pin 23 and using return of pin 46. Looking at the different engines with a KS all of them use pins 23 and 46. I think I might stop at the junkyard and pull a knock sensor and try what he outlined earlier.

Any luck?

I haven't tried this yet. I'm focusing on getting the M90 fitted on my truck.

Oh my! Too much fun!
What are you using for a TB?

I'm going to use a 60mm off of a 94ish t-bird 5.0. I've been searching for a 94-95 cobra TB on ebay but couldn't find one for cheap.

Good choice, it has the IAC built in. Makes set up a breeze.

Thats what I found out. I'm also going to use the sc inlet from the t-bird so I don't have to make one. Hey boss what did you use for a nose support for your set up?

On the charger itself? No nose support, it just hangs there.

But your using the downward discharge m62 where I'm using the m90. I'm just asking because I have my manifold done and I just need to figure something to keep the belt from pulling the nose down. I'm using the upward discharge eaton.

Gotcha...
Does the blower feed UP to the intake, like the Whipple?
If so, a snout bracket would be a must have to keep stress down. You want as tight a wrap possbile (180&deg or more) on that supercharger pulley, because it slips quite a bit. I have to clean off tiny bits of rubber now and then that get flaked off. I would LOVE a one-off 10 rib pulley set (...oh Santa!), that would be sweet. Sounds like a project for the Whipple...

Hopefully I won't have a big problem with chewing up belts. I'm going to only use the 6 rib belt. Do you know a site to get good cheap belts. Thats one of the next steps. I'm getting closer and closer to being done!

Bump

Have you found anything out BOSS? I've still been working out bugs in my SC setup.
