[paulwayman]

just i have heard you cannot de cat these engines as you get running problems is this right has anyone got this done on aum engine

think there is alot of people that run AUM's with de-cats. It will fail mot on emissions and think you need the lambda elements mapping out

Only issues are engine light due to a higher reading from the rear 02 being out of the threshold, but with one byte change in the mapping the car will run 100% spot on with out any engine lights or fault codes.

thought so as any car should run ok with no cat just cell light need wiping and a map to get best results
