09 6.7 New to me, OEM IAT probe question
Hey guys, I figured I'd start posting here on my new truck. Well new to me, I just bought a 2009 Ram 3500 Laramie 4X4 crew to replace my 06 5.9 dually. I bought the truck at an auction in Omaha NE so I don't know the history but what I do know is that the entire exhaust and DPF has been deleted so it must have some kind of tune in it since I flew to NE and drove the truck 1800 miles back home to Florida. It does have the check eng light on as well as the DPF FULL light & alarm going off and the overhead SEE DEALER NOW or whatever light on. So I removed the EGR last monday and installed a delete kit and it still ran the same. Then a couple of days later I was at the local salvage yard and I found a almost new 2nd Gen turbo setup with a DPS manifold and a BW S300 SX 66 73 80 turbo with a .091 ex hsg, so I snagged it along with the thicker 2008 intercooler. So I've stripped the stock turbo setup along with the stock intake setup also and I am installing a Pusher intake to cleanup the intake side. I have a couple of questions that maybe someone can answer for me. Is the probe that came out of the OEM intake an air intake temp probe? And or does it actually measure IATs for fueling or is it just for the EGR or is it to tell the grid heater when to turn on or off? I was able to get a 1/4" to 1/8" brass reducer at my local hardware store today so I can install it in the Pusher intake if it is worth it. The AC compressor was a little week and the condenser was a little beat up from the road gravel so I am also replacing everything except the evaporator at this time. Basically I am taking this opportunity to change the water pump, serp belt and rad hoses along with cleaning half of Nebraska off of the engine and drive train along with adding some mechanical upgrades. So my intention is to add all of these mechanical parts and see if the truck will run after unplugging all of the stuff on the intake side, or will it go into limp mode? I guess there's only one way to find out right? I just took the exhaust manifold, turbo compressor hsg and a 5.9 thermostat hsg to get ceramic coated today so it will probably be a week or better before I get it all back together to run it and then we'll see. Obviously at that point I will probably need to make a decision on a new tuner and engine monitor device be it a Edge CTS or A pillar pod with gages. I still have my 06 5.9 to use until I get this truck the way I want it. I did an oil analysis and it came back good and all of the fluids are very clean and there is a decal on the passenger side of the trans indicating it's a Mopar reman. The truck has 178k on it. Any tips would be appreciated since this is my first 6.7 and my first electronically controlled engine that I have really messed with since my last hot rod diesels were my 12 valves and my 5.9 I have left basically stock since I purchased it. So I'm kinda ready to turn this one up a little bit.
