    GM 6.6 Duramax turbodiesel

    Ok, so basically this sensor sits on a cam that connects to the vanes. The tip of the sensor is lubricated in oil, so tip is being cooled. I can see how the center of the turbo is cooled with oil along with the tip of the sensor. I don't see any lines for antifreeze. I have attached a pic...

    GM 6.6 Duramax turbodiesel

    @Moon161. No this isn't a homework problem. @mikehalloran. So even when the turbodiesels have EGT's of 2000F, the bearings and the shaft are within the oils limit below 305F(typical)? I have seen photos of complete turbos turning red, that sure has to effect the turbo vane position sensor and...

    GM 6.6 Duramax turbodiesel

    Hi, I am doing research on a turbo vane sensor for the 6.6 GM Duramax. The sensor rides on a cam which entail reads the position of the vanes. I am curious to know how hot that sensor will get. If the EGT is about 1200F, and the turbine housing is 1200F then wouldn't the sensor which is bolted...

    While the information from the manufacturer is propeitary, there should be some engineering information available?

    TPMs reset requiring magnet, why?

    Hi NormPeterson, I checked Bartec, but no detailed info. I am under the assumption that to get to the basics of this I would need to consult a RF signals textbook or something similar as the manufacturers service manuals are tremendously vague.

    TPMs reset requiring magnet, why?

    Hello everyone, Curious to know why a magnet is required when resetting certain TPM systems. Somewhere I read it is to make the signal stronger and to notify the receiver of which wheel you are programming, another statement I read was there's a reed switch inside the sensor and the magnet...

    So currently I emailed a few professors, many have pointed me to the Bosch book. To me this is to vague. crerus75 : Where can I find data sheets on sensors?

    Book recommendations

    Thx guys for the reply. The end game is basically how to test the parts properly and the theory behind it. OEM data is non-existent so I can only go by all data and similar programs or factory service manuals that are unbelievably vague. I am going to check the SAE books also as they have some...

    How to duplicate Saab coil ionization signal without engine?

    MikeHalloran - That is a good idea, but it's a cassette with non separable coils(4). Comcokid - This is correct, but I need to confirm the cassette is receiving and analyzing the signal from the spark plug. Eliminting the cassettes output, wouldn't help me determine if the cassette is doing...

    How to duplicate Saab coil ionization signal without engine?

    Hello everyone, currently working on a Saab direct ignition cassette. There are no difficulties to get it to fire, but I cannot duplicate the ionization signal or knock signal(obviously I cannot do both without a engine). Is their a way to duplicate the ionization current and feed it through the...

    Aftermarket Ignition trigger signal compared to OE

    We have a generic Toyota style ignition driver box which we use to bench test the coils. The output of that box is 5V and I measure the current on the trigger signal wire. They both fire with the same inputs, 14V to the primary and 5V to the trigger circuit. The coils both fire and I get...

    Aftermarket Ignition trigger signal compared to OE

    Hello all, I have a question regarding the trigger signal output supplied on a coil on plug. The OE has a trigger signal of 2.0 mA and the aftermarket has a trigger signal of 4.2mA. I have not tested the coil on the vehicle(do not have it, only bench testing). From my understanding...
