Install an aftermarket EGT probe.

If you don't wantto buy new ones you can get non-flight certified setups at a lot of aircraft wreckers for VERY cheap. They also have the added benefit of being vibration proof.

pre-turbo is most accurate. I find that pre vs post turbo readings can differ a couple hundred degrees.

Pre turbo is the only thing that counts.

I can't see installing that on EVERY car that goes on the dyno ... especially a 2.7t

Post-turbo is OK, if you have experience with pre vs post on a car and know the approximate difference.
For 2.7T it is easy, you already have the factory sensors. Just install a factory sensor and remove it afterwards.

You mean an RS6 wideband?

You don't need a wideband EGT, although it's beneficial.
It's important to not exceed a certain EGT, not so much know all the time where it's at.
Unless you have an EGT sensor on each cylinder it's pretty useless for mapping.

So I made a screw up today...
I was on the phone while editing my KFZW table...
It seems I typo'd a section of the table. The result was an 8 degree ignition timing spike at around 4000 rpm @20psi of boost...
This lifted the heads and blew out both head gaskets at WOT :/

Time to get cracking with my built engine...
Be careful guys all it can take is a typo!

That sucks but also shouldn't have happened.  Was it a tired engine, old gaskets?

OEM bolts?  New when installed? Torqued with a torque wrench

Yeah I know...
It was a used engine out of an A6... so used is used... no way of knowing the actual condition of the internals...

Ah well, 3.0 it is!

Since we are all here, do you think it is possible to wire in the 75psi Map sensor that my ZT-2 is using and run the 5120?
