If your datalogger has external resistance ports on it, on 2006+ Duramax Pickups, there is a fast acting resistance based pyro sensor for the post-CAC manifold temps. This means no amplifier needed (not like a thermocouple). On 2007.5+ trucks there are also resistance based exhaust pyros that go past 1832 F yet, are also suprisingly accurate at 0 deg (after mapping the curve). This would also make a good CAC pyro. I mapped both of these, and the inlet pyro is fairly linear IIRC, but the exh pyro is only linear from 800-1700. You need to adjust the data in other areas.
If you are interested, I can dig up the P/N's. One thing about OEM sensors, is that they are way more durable than most aftermarket stuff. They have to last over 50,000mi for EPA crud.
