EGT vs WB02??

[Superskwrl]

I was wondering what everyone's take is on tuning with an EGT vs. Wb02

I have the wb02, but not the EGT setup, is there any benefit to getting an EGT setup?

Well the wideband wont tell you when the pistons are blobs of aluminium Use both be safe

What kinds of egt temps are ppl seeing? I gather that it will be different depending on where the sensor is located. I have my sensor located in the turbo exhaust inlet housing and run about 16,000* to 16,500* at WOT. I would think it may show a little cooler at the head exit (exhaust manifold/header).

With a rich tune i get 1650 in the factory o2 sensor location@25psi and 11.3 a/f and 26 timing on c-16.

I wonder how much difference there is between the location before the wheel and after the wheel. Your location being after the wheel. Do you think it's about the same.


I am running 27# of boost with an AFR of 12.0 @ 26* timing and a 50/50 mix of c-16 and Sunoco 94. I get about 2-4* of knock at the 1-2 shift and at the TCC lock at the top of third. The knock is directly on the shift point... assumed it's probably shift related. My o2 correction is +/- 3 at WOT.

With my egt at 16,000-16,500 before the exhaust wheel, I am wondering if my next step in being a little more aggressive in tuning should be boost, timing or afr change. Any suggestions?
