therealcc Posted August 8, 2013 Share Posted August 8, 2013 I am getting things ready for a tune on my 05 OB XT. I am about to get a DP then a tune from Revolutions Performance in Colorado Springs. I was going to get an EGT sensor and oil pressure sensor, but I saw that EGT sensors can break off in the up pipe, etc. This is my daily driver and my main goal for selecting which gauges/sensors I get it so be able to see if something is going wrong before it causes serious damage. Does anybody have any suggestions/advice? Thanks Link to comment Share on other sites More sharing options...
ctlex Posted August 8, 2013 Share Posted August 8, 2013 Wideband o2, oil pressure and boost. Link to comment Share on other sites More sharing options...
Benjamin M Posted August 8, 2013 Share Posted August 8, 2013 I plan on getting Boost, Wideband 02, Oil Pressure, and EGT for my 05 OBXT; using the VEI D-1 series gauges, so much data, yet so compact. Link to comment Share on other sites More sharing options...

therealcc Posted August 10, 2013 Author Share Posted August 10, 2013 I ordered the JCS cubby pod and only have room for 2 gauges... so should I do a Boost or Wideband O2? I'm most concerned about detecting and preventing a major breakdown before it happens. Link to comment Share on other sites More sharing options...
Benjamin M Posted August 10, 2013 Share Posted August 10, 2013 Haven't ordered it even yet! haha It's just my plan, but I will reference Nrw's set up (pretty much copying him haha) Post #165 http://legacygt.com/forums/showthread.php/nrws-2005-bsm-gt-194060p11.html?highlight=nrw Link to comment Share on other sites More sharing options...
CapnJack Posted August 10, 2013 Share Posted August 10, 2013 I've got the STI gauge pack (Boost, Oil Pressure, Oil Temp) and an LC-1 Wideband O2 mounted in a JCS a-pillar gauge pod. LOVE IT! On a built car, the three vital ones, IMHO are Boost, Oil Pressure (especially on an 05/06 with the oil pick up problems) and a Wideband O2.

Dujo Posted August 11, 2013 Share Posted August 11, 2013 You don't need EGT. The stock EGT is used to make sure the uppipe cat in the 05-06s doesn't reach melting temperature and come apart and grenade your turbo. It is not used in any fueling calculations either. Regardless, you should be replacing the uppipe with an uncatted version to really be proof from this design flaw anyway. If you remove the cat, the uppipe EGT becomes superfluous. An aftermarket gauge running in the stock uppipe location would be in the wrong place to measure true exhaust gas temps as well. The EGT sensor needs to be closer to the exhaust ports by moving upstream into the exhaust manifold to get an accurate reading. Besides, afr will tell you the same info that's important for EGT, which is that you are running way too lean which causes exhaust gas temps to skyrocket and promotes detonation. Boost and oil pressure are most important to see if you are maintaining known air pressure to match your tune (no unmetered air) and make sure there is always good lubrication as the stock oil light is set to something like 2 psi, which really just makes it a replace engine light.

therealcc Posted August 11, 2013 Author Share Posted August 11, 2013 So you think go with Boost over Wideband O2? I already replaced the stock uppipe with a catless one. Link to comment Share on other sites More sharing options...
