I went in today to get tuned at s-squared and the baseline was low. I was only putting down 230whp and about 220tq. While tuning, nate said that he would finally set the afr's to about 11.2 and then all of the sudden it would just get hella high and then drop down to like 9 or 10. We ran the cel code and nate told me that i needed a new fron 02 sensor. With the messed up 02 sensor i ran 250hp and 260tq. It was a lot less than I was expecting but nate said that after i get the 02 sensor fixed it should do much much better.

Does anyone know if the Perrin o2 simulator would work in place of the o2 sensor? Id rather buy that instead of paying $215 just for the o2 sensor.

 

You don't want to run a simulator on the front 02 sensor, that's the one that actually gives the ECU feedback on how the car is running. The rear one is just for emissions (post-cat) and is the one you should be ok with a simulator on.

 

Damn. Now i gotta spend another 400. lol. Thanks though. I'll see u at the meet tomorrow.
