Just got a gauge kit (pyro/ tranny/ boost) & the turbo temp monitor. All Isspro from DieselManor. The turbo temp monitor (TTM) installs post turbo & shuts the engine down at 300*. I am going to go pre turbo for the pyro. Reading the instructions for shut down recommendations that came with gauge kit, it says to shut down @350* pre turbo or 300* post turbo. Here's what got me thinking. It says exception for pre turbo applications, that after a hard pull wait 3-5 minutes after you reach 350* because of residual heat. So with the TTM being post turbo & shutting down & 300* would residual heat be a problem? I don't think it is but I don't know. If it is, the TTM wouldn't be worth installing. The fact that it shuts down based on temperature versus time is why I bought it in the first place. She'll be panting hard when I stop. So do you think the TTM is OK ?

 

I would stick with pre-turbo , and shut off at temp , becouse thats what realy counts , not time ,
I think you answered your own ?

 

I was going to install the same TTM but the mfg doesn't give you wire color coding.
When your done. could you let us know the colors of the wiring you tapped into.
I have an 04.5 it's probably the same.
I just don't want to trigger the air bags by poking around. That would ruin my day.

Thanks

You could install the TTM post turbo and then use your pyro gauge to see how the TTM performs. i.e. do a hard pull and then see how long it takes the TTM to shut down the engine after the PYRO gauge sees 350. Hopefully that residual heat will be transferring back into the exhaust enough to keep the TTM post-turbo probe above 300 for the recommended cooldown time.

 

Just a side note. All the wiring for airbags are ran in a yellow hoses and or yellow split loom, and use yellow plugs. And don't for any reason ever use a test light on airbag wires.

 

I have an Isspro TTM on my truck, the directions say to put it post turbo. that is how I have mine and my gauge pre-turbo. I can see the egt's on the gauge go below 300 deg. long before the TTM shuts down. Just going by the pre turbo gauge if I shut it down @ 300 deg. the exhaust temp will go up 400+ deg. after a few minutes being shut down. It doesn't go up if I let the TTM work

 

after a hard pull the shaft in the turbo is very hot, much hotter than the air passing by it. you need the shaft to cool so the oil will not coke on the bearing.

 

DR3500 Could you let use know how to hook it up. I'm not sure what wires I need.

 

I hooked it to a solid red wire for power and a solid light blue wire for control under the steering column. I don't know if the wire colors are correct for the '05's though. the red wire is hot all the time and the light blue one is hot with the key only in on, both wires are 18ga I believe. It does work with the Sentry key, but I get brake warning, ABS, and an airbag light once I turn the key off because they see no power from the TTM. I also get a 480 (cooling fan control low circuit) code. I have had no other issues with it though.

 

Thanks DR3500, I'll check it out when I get from free time.
