Low idle Co2/HC readings with Decats

[Jellybean]

Hey

 

does anybody know what the Supra will emit on Low idle (1310 rpm) Co2/HC with Decats , will 264 cams affect the emissions?

 

Mine with first decat and unknown 3" pipe 2nd cat with OEM cams was CO 0.37% HC 75ppm

 

thanks

HC's will go up with more overlap or duration. You are asking some bizarre questions these days....

Lol there's logic behind my madness; was thinking of getting a 2nd decat fitted prior ecu mapping but nopoint if she won't pass the Nct (mot), I would not be into swapping out cats annually

Rather ask the q that splash out 200gbp and hope

Just get the mapper to do an extra 'MOT map'

[Jellybean]

Will see if the ecu can take a dual map not too keen on going back each year

 

Yes I want to have my cake and eat it too

If it won't store more than one map in the ECU why not just keep the emissions map on a CD and load it yourself when needed?

Just taught of that after I posted , thanks again Chris!
