Read Second O2 sensor in OFT Stage 2 Tune
 

I'm moving back to fascist Massachusetts and need to pass inspection. I have a JDL catless header and an OFT stage 2 tune which makes the second O2 sensor will read as not ready and I will fail and probably be red flagged. Instead of installing the original header I plan on using an O2 spacer.

This means I'll either have to flash back to the original tune which I know reads the second O2 sensor, or modify my current map in RomRaider to properly read the second O2 sensor which I would prefer (has things like quieter start-up which could help me during inspection). How might I achieve this via RomRaider?

Also a long shot, but does anybody have experience using the Vibrant or MXP O2 spacers?

Much thanks!

Ots roms do use the Second lambda, they just disable p0420 dtc error i think. You could just enable again the code and hope that it doesnt trigger CEL immediately or yes, use also a spacer

Don't they do a visual inspection in MA? They will see there's no cat. Also, the car will fail the readiness test with the OFT tune and they can see if the P0420 is disabled (I think anyway). Others have posted in here from MA and they are pretty hardcore on emissions there.

You'll have to run a while on the default tune so that all the readiness tests have been run, so an O2 spacer may be your best bet. You can't clear codes then run real quick for an inspection, this much I am sure of otherwise everyone would do it and it'd be too easy to beat the inspection.

Hey, we need a Masshole for this! Where you at??
