29-12-2023, 02:46 AM #1can i please have the required info so that i can disable the rear o2 sensor, i only have a single cat and the OBD is telling me the efficiency is below threshold, with resistors not the anti foulers, thank you
I do a box that replaces the rear sensor to fool the ecu into thinking everything is fine.

30-12-2023, 07:30 AM #3i don't have any pre-cats, i only have the main cat installed, is this what is needed to sort it out? i can solder and make whatever is needed myself? i don't really want to buy a box if i can learn and build it myself but obviously i don't know what to make.

30-12-2023, 08:54 AM #4I'll be honest mate I'm not going to reveal what's in my simulator box as it's a product I sell. But it's certainly more components than that and i could tell you or not if that system pictured would work.

30-12-2023, 10:48 PM #7Stav would your box work if I took 1 of the lambda out of the precats so I could fit my air/flo in its place?

@is200turbo, you can wire up both the front sensors to one single lambda with no issues, join the plugs wire for wire and run one 02 sensor then you'd have another hole for your wideband.

01-01-2024, 03:16 AM #10and there was me just assuming he had a turbo because of his name, why even add a wideband sensor to a car with pre cats?
