2nd owners woe's - WTF is this lead?


Recommended Posts

Posted

88, 5.7 TBI - It's a 2 wire lead with it's own plastic covering, that comes out from behind the relay box on the passanger side of the fire wall, towards the TB.

 

Mine is cut! Just cut! I was thinking IAT sensor lead since I can't find my IAT sensor anyplace.... Does anyone know "For Sure" what it is? I can take pics if need be.

 

Thanks,

GOY

Sorry it took so long. I just got back in town.

That wire goes straight into the hood light on my 92. Right above where it comes out.

god I feel like an idiot... lol.

 

Well, the hunt for the IAT is still on  :banghead:

 

 

 

 

IAT sensor what is it?

 

 

 

 

 

Intake Air Tempature.... I only assume that a MAP based fuel metering system would have to have an IAT sensor. The MAF TPI sensor were capable of running nearly perfectly without one (althought they still had one), since the wire tempature could judge both density and flow, but since MAP is basically a big vac. sensor, I wouldn't understand how the ecm could calculate air density without one.

 

Maybe I'm misguided however - I'm new too the land of T B I :thumbs:

    • Late reply, but yes—it works on the SLT trim. Compatibility comes down to the plastic shroud shape behind your mirror, not the trim badge itself. On the SLT with auto-dimming, it uses a plug-and-play Y-harness off the mirror/rain sensor power, so no need to run wires down to the OBD port. If anyone's ever unsure about fitment, just drop a photo of your mirror housing and we can double-check it.   Appreciate the detailed feedback on the install! On the windshield glare—we actually took feedback like yours and developed a dedicated CPL (polarizer) filter to cut down dash reflections on sunny days. If you're still running the cam, shoot me a DM. I'd be happy to send a CPL filter over for you to test out—no charge. 
    • There are no stickers in your glovebox?
    • Look at the numbers on the stickers in the door jam...
    • Yes, every time the developer updates his code, you must recompile. I will private message you with the latest because it changes pretty much with every version.
    • After I wrote that reply I went for a ride. 85 F out. So trans started at 85 F and it shifted the same as it did an hour latter at 168 F. I've never actually recorded the to cold to shift point but it is under 32 F before they start hanging on to a lower gear or leaving the converter unlocked. Both intended to heat fluid.    Yes, brake or bake. Absolutely.      Your welcome. True research ended decades ago. Field trials are still in play.    There is a thing called oxidation onset temperature. This is the heat related oxidation not the O2 exposure kind. For mineral oil that starts at 140 F. So what happens after 140 F? Each 20 F cuts fluid life in half! Does using a Full Synthetic improve that? Yes! By how much? Depends on the base oil type and a few other factors. But enough to notice. Some esters are even higher. There are even synergies between types the will raise it higher than any one component is alone.    Then there is "Hindered" oils. Antioxidant additives. Hindered Polyol Esters can sit at 500 F for years in a turbine.   When a blender brags his oil will 'take 500 F" in service he doesn't specify for how long. Water will dance on a 500 F hot plate for several seconds. @newdude put up a chart showing the relationship between fluid temperature and it's life in an automatic transmission. Here's a version of that chart for Group III based oils. These temperatures are those in the pan as observed as 'normal'. that is you drive as you do for as long as you do under what load you ask of it and whatever that temperature is this graph applies to. Flash temperatures of a few minutes isn't what his means.    Note that fluids held at a constant 240 F have a service life of only 20K miles. 220 F explains the factory exchange limit, eh? My equipment I keep under 180 F and I'm good if the cooler will hold it as low as 140 F. But that's me.
