This is a bit of a problem, as egt must be measured VERY close to the port (usually right after the header flange) and this is only done in serious shops/dyno development. Additionally, the ideal egt of ANY engine is largely UNKNOWN unless determined after comprehensive bench tests of the particular engine. This is why I haven't installed an egt gauge in my 1.8T. What should it read? Ideal egt's are vastly different between engines. Therefore they must be used as an alarm to monitor engine condition when the value shown changes suddenly.

Getting too involved for someone like me. I think that’s why in OKTechs car he has 6 EGTs at the exhaust flange. That’s beyond club/hobby levels. I have to stick to AFR.

But for knock I might be able to do something. What device do you recommend? Phormula? Or Maybe a seasoned ear?

Found this video, not a bad device TunerNerd Knock Monitor Pro, only $300+.

I used Knockling G4 to help properly map ignition advance on my 1.8T with very good results. I do have a good ear and knocking is very evident on the turbo, but this gizmo is even more sensitive. It's not a permanent install, just used to verify mapping. It uses the oem 1.8T knock sensor located on one of the intake manifold lower studs. For the 24v, the dyno shop has their own knock sensor gadgets.

A seasoned pair of ears…..wait MD has very seasoned ears…he’s heard a lot of things in his life. Wonder what he has to say about this.

Anyway, I’m gonna get me one of them knock detection devices for my next dyno session…hopefully I will have adjustable cam gears by then….
