My ecu threw a code for the primary 02 sensor. So my tuner disabled it through fp. My question is, even though the engine light is off, will the car still be in limp mode? It seems to work well at wot but I don't want to keep driving it if its pulling timing. My tuner said its fine but I'd rather hear from you guys.
Main reason I ask, is because when my knock sensor went, we disabled it, and even with the engine light off, it was retarding timing.
Car is an 06 si turbo, 350whp@9psi. Thanks.
02 sensor question
Re: 02 sensor question
You really should replace both damaged sensors. We do not recommend disabling the knock sensor. Without a working O2 sensor it will not be able tu run in closed loop and your economy will suffer.

Re: 02 sensor question
oh i fixed the knock sensor right away lol
the weird thing about having the 02 sensor disabled, its actually running gas mileage now. the afr on the wideband always stays from 14.9- 16.9 when cruising. and yes i know 16.9 is way too lean but theres no load on the engine while having those numbers.
my main concern was just if its safe to drive it like this, i will be putting a new 02 sensor in next week thanks for the response .
