    I've got that gauge sending unit in my car for temperature (single wire right?) and the pull down resistor and the equation if you want it. The equation gets a little weird at room temperature so when you start the car it will tell you that the oil & water temps are like 5 deg. I'm guessing they get weird at really high temps too, but in the 190-220 range they are correct having checked them against other known temp senders.

    Fuel pressure - autometer makes a fuel pressure gauge that has a three wire sender, will work in parallel w/ the gauge and the DL-1. I have a fuel pressure gauge w/ very technical change to read oil pressure - a small label says "oil" stuck over the "fuel" label. This reads on teh DL-1 w/ a pretty simple equation that the DL-1 will create for you w/ a couple of data points (it is linear, whereas the temp senders are not). I think I have this one: http://www.summitracing.com/parts/atm-3363/overview/

    Shoot me an email or give a call if you want to see how they are wired.

    Another option is the Autometer Elite gauges. They all have a 0-5V output from the gauge to connect to a dash/datalogger.

    The gauges are quite nice--they can change color and flash to alarm on under/over range.

    I think The Boys already have a R-T dash that comes with limit warnings and flashy LEDs....

    I have a dash 3 So I think I can program it as Greg mentions. I really don't want to buy more gauges our use any part of the ones I have. The idea is to eliminate the gauges I have and give my entire gauge package to my brother and he can buy me the sensors to utilize my dl1 and dash3

    Well, the easy button is to buy sensors direct from Race Technology, complete with the harnesses and already-programmed-in functions/formulas.

    Oil/ Fuel Pressure - http://www.race-technology.com/oil__...ure_8_976.html
    Oil/diff/water temp - http://www.race-technology.com/water...ure_8_973.html
    Water temp - do you have the OBD inputting to the DASH3 so you can set alarms? If not, same sensor as above.

    My oil temp sensor is screwed into the oil pan; water temp is screwed into the head (drilled and re-threaded the stock hole); oil pressure is tee'd off a braided-steel line mounted to the firewall, with the other side of the tee going to the stock dash idiot light. For temps I'm using R-T sensors; for pressure I'm using the lesser-expensive Autometer oil pressure sensor, as pressure is a straight linear-voltage function (temp sensors require step-down resistors to convert the output. Not difficult to do.)

    Ok, awesome! Dam that oil pressure sensor is pricey!

    You mentioned above you have some sensors.... some you want to sell or are you just saying your using them...

    Which is why we're using the Autometer one. I seem to recall it was about $50 or so. I'll have to look up which one I'm using; Matt, do you remember the right one?

    I have three Bosch 0281002170 sensors available. Problem is, that's the "old" style oil temperature sensors and Race Technology does not make the harness for that any more. I have some (2? maybe 3?) damaged wiring harnesses that have the correct plug for it, and I've got the correct resistors (from Radio Shack) but they'll need to be repaired. Buy me a 12-pack of local NH IPA and I'll give it all to you at LRP (pls remind me via email to bring them with me).

    Problem I had with those is that the wires were breaking at the pins where they went into the sensor plug. Fatigued, broke off. I found out just this past month that R-T changed to using the same sensor and harness for both water and oil temp, with an improved wiring harness, so I bought a whole new setup for oil temp. These could actually work for you fine if you can find a good way to stress-relief the harnesses to stop them from fatiguing.

    Greg, I am not sure what you mean by harness. I have zero wiring going out of the dl1 other than gps and CAN BUS adaptor. Oh and a video thing that I never used...
