Hello there,

Sorry to ask but can't search.

I have a Supersprint DP + mid + backbox. No cats behind the turbo, just one before, but not long time ! !

I have CEL since the Supersprint and I wonder if I could go with a Scoobysport DP + 3rd OEM cat + Scoobysport center + Scoobysport backbox with no CEL.

It would be both noise and emission friendly :-)

Did someone try the same setup ?

Your feedback is very important. Scoobysport rules in UK but here (in France) the decatted DP replace both 2nd and 3rd cats, so nobody could try.

Thanks a lot

 

The reason the CEL comes on is because the rear Lambda sensor is telling the ECU that one or more of the CATs have failed (or in fact in this case, is/are not there )

Presumably you don't want to re-introduce any Cat's, so the answer is to fool the ECU into thinking the CAT's are there. Scoobysport do a box of tricks which does this for you but I've also heard that they only sell this to owners of SS systems, whether or not this is true, I don't know but would suggest you phone or mail Scoobysport.

The sensor in the centre section is positioned
before the 3rd cat so replacing it wont make any
difference to the signal being sent to the ecu.

Thanks for all M8.

I have ordered the OBD-2 scantool in the States for 79$ so I will be able to reset CELs.

In ordre to prevent them coming, I should think to Pete Croney's "Litl'Black Box"

Bye
