3.7L V6 QT1 to QT2 Conversion.

Changing the ratio would be a bit of a pita every time you switch back and forth anyway (well unless you leave it in the whole time).

I wonder if you could add some sensors to the CVs up front near the diff..... the rear would be a bit more challenging

I agree, any ideas on location and mounting would be greatly appreciated.

I know how to switch between the wheel sensors, but where to mount the tone rings and sensors? The tone ring count at each wheel is 48 stock, I confirmed that last night, the front and back are the same count, the additional tone ring would need to be 18.

I was actually going to mention signal conditioning earlier.... but wasn't sure if its possible to manipulate a pulse like that? (I'm sure my advanced equations professor would slap me for saying that and remind me of a basic Fourier transform that could do it....)

[Matt]

..... and the fact that an $85 off the shelf component can do it makes this idea very promising!

Put those ideas out here! Thinking outside the box. My thoughts as well, I found one on ebay for $80.70, I can't make many parts for $80.70. Now is the wheel sensor a square wave pulse? And does this conditioner do square waves?

[Matt]

I'm not an electrical engineer.... but its just a hall effect sensor which is (I believe) a square waveform..

If the conditioner simply gives an output based on a multiplication of the input waveform pulse count, which it sounds like it does, most of the work is done. Just need a way to control the conditioner "on the fly"...

I'm pretty sure you are correct on the Hall Effect switch. I'm not electrical either, just a mechanical engineer. I have an email into Dakota Digital. It appears our wheel sensors are +12vdc powered and the return signal is -12vdc. Reading their manual, it talks a lot about two wire, but one of the wires being ground and the other being the signal.

I have a way to switch between the two. Using my PLC and changing the program slightly. I can control relays to "toggle" between the two. Running the wheel signals through the conditioner if in Low range, and then bypassing the conditioner if in Hi range. I'm thinking this is all possible. Just waiting on a reply back from Dakota. Thanks Matt for the help!

[Matt]

I'm actually working on my masters now (one class at a time!) and my professor is an electrical/controls PhD.... I should get his input. I'm sure he's consulted for much more complicated systems (actually I'm positive of that)

[Matt]

Good news... at lecture now and my professor is on board.

Cool, stick with the Masters program. I've been designing automated equipment for 20+ years, I wish I had stuck with it when I had the chance.
