Mapping cost to switch off O2 sensors?

[thedon]

I regularly get P1146/7 error codes because I have HFCs.

 

The car has already been Uprev mapped - how much just to switch off the O2 sensors?

 

Also anyone know somewhere that can do this near Suffolk? Thanks.

Cany you use spacers?? Got mine from Chris at tarmac sports and works a treat.

[thedon]

Cheers - what do they do? send no signal at all?

Most tuners will switch off the sensors as part of the Uprev tune.

Thanks Alex, but Horsham obviously didn't. It was mapped before my time, hence wondering how much it would likely cost to simply switch them off now.

 

Would you suggest spacers as a cheaper option?

Strange , we usually do

 

Spacers might be a cheaper option than fuel to go somewhere to get them switched off

Thanks, Rich. Do spacers stop the error codes triggering the EML?

You're teasing me... why only sometimes?

On some cars with some hfc it works and others it doesnt

The spacers effectively move the senor further away from the exhaust stream, theoretical seeing less co2?

I am running Silenced Japspeed Decats with the "Generic" Right Angle spacers,

Spacers work some and not others. They didn't for me, so I went in for an upRev to sort it. At the price, they're definitely worth a shot.

If the o2 sensor doesn't report back with a fault after a ecu tweak, how will you know when they are faulty, or is it just the tolerance level that is altered?

Its the post cat sensors that are switched off, the pre cat ones are still used .

If HDev usually do turn them off it might be a actual fault?

We usually turn them off if the car has decats or hfc's there is no need to if the stock cats fitted
