I just got my DEFI gauge package and one of the gauges is an EGT. So where do i put the damn EGT probe? Some people tell me to pu it on the up-pipe but im not really sure if that would be a good place? Help me out here people.

 

Most people tap the casting button on the drivers side manifold since cylinder 2 and 4 run hotter than 1&3 on a stock setup. I didnt like the idea of only takeing readings from 2 of the 4 cylinders so I tapped the collector.

 

tap into your manifold, thats where people usually do it

 

Put it on the exh manifold...cyl #3...

 

Assuming he has the stock manifold why would you recommend #3? A guy over at another Subaru site did some testing with a 4 channel egt gauge and this is what he came up with.

Stock setup

2-1597
