One toy I always wanted was the TS Performance MPD HUD, but it only reads boost from the ECM, I wonder would there be make it work with this sensor?????? nice and stealthy!
100 PSI Boost into ECM feed.
- Thread starter McRat
- Start date
I had one, never did get it to read anything but boost(max 38) and EGT, no rail pressure or rpm. Customer service sucked.
Nice Pat, this is very useful for aftermarket charger trucks.
Here's the "Wet Dream" - To capture boost and EGT's in datalogs without any EXT feeds when running more than 30PSI boost.
By the end of the week, I should get it all finished up. Finally.
pat heres your widget to convert your standard type-K thermocouple signal into a linear 0-5v signal.

Good link! I'm still committed to using the LMM pyro due to it's survival at very high EGT's. My problem is that I can't more than 2.5v range because I don't know enough about circuit design.
I'm wondering now about re-tapping one of my stock EGT probes pre-turbo and peeling the wiring out of the harness that runs down the framerail to change sensor location.....Hmmm, i'm glad you posted this!!!
If you are looking for a chip level converter:

What's this about 2.5 volts? Pyro supply voltage?
The LMM pyro reads out in Ohms. I need to convert that to 0-5v. I convert it, but only get a 1.0-3.5? volt sweep. That will work, but it would better to have 4 volts or better sweep so the data has more resolution.
That is a circuit I would like to see Pat......
You need to energize the circuit with a constant current source while factoring in the influence of your measurement equipment.
Use the chip. It does it all in one package for you.

That chip looks like a good resource, the only issue I can see, is that it will read 1v at 212F, and 10v at 1832F, so it needs a resister to divide the voltage in half. It's used with standard thermocouples though, not the LMM style.
Voltage divider. So two resistors in series. Supply voltage to the outside of two resistors then tapping between the two for the divided voltage. Two 1Meg resistors would work well.
pat do you have a PN so that we may purchase this or have you considered selling it yourself?? I for one am interested in this.
I should be done testing this week, and if it works, I'll provide a link to the sensor. Kinda sucks since I've spent a few hundred testing different models, but I've given up selling anything for the most part. It cost me more to sell stuff than any profits I get, with the exception of EFILive and tuning.
Is the EGR Position sensor set up the same as the factory boost sensor as far as inputs and outputs? If so I'll probably get 2 of these so I can log boost vs. drive pressure.
I found this tonight slumming on gasser trash boards.

So does anyone know what are pigtails are for the factory boost sensor? Or where to find this info?

Sorry folk, I was dinking with other stuff.
I'll post up this weekend. I have to find the invoice for the sensor.
The color codes in my earlier post are correct.
