100 CELL CATS - worth remapping

[Das Chin]

hi all

my recently acquired car has 100 cell cats. great when you are moving but a bit lumpy when down low.

can anyone recommend getting the car re mapped for this as it does seem to run rich and the rear bumper is a bit covered in fuel.

happy to do a swap with some normal CATs if anyone is interested?

this doesn't sound quite right....run 100 SS Cats myself and have no dramas.......wait for adem.csl or gorilla to inform us all.....

Same here... although the EML light does come on sometimes, especially if taking it easy after a TD or enthusiastic :whistle: driving.
Nothing that my diagnostic tool can't reset though :-D

You guys need to get an EVOLVE tune for your cars. They do some nice tuning for the CSL.

You sure it hasn't been remapped already? Don't recall my car chucking fuel out the back with 100 cell cats.

[Das Chin]

no not remapped.

has 100 Cell Milltek Cats and the AC Schnitzer back box.

the light that comes on is the one below at the top of this picture



the flap motor has packed up and waiting new so wondering if that has triggered it. emissions altered as a result with the flap opening and closing.

will disconnect battery and see if that helps first.

will get the new solenoid actuator, fit then and then do a diagnostics.

could be an O2 sensor from CAT back that has gone too?

only a minor thing as running fine.

Check with a GT1 instead of guessing what could be wrong mate.

Low down stuttering at wide throttle opening will likely just be because of air flap

Can you not just remove the flap/motor..?? Mines not attached since I bought the car (it was in the boot)

got a new one coming steve as previous owner had one on order but coming from Germany.

will get that fitted first to see if that helps out.

Why would open flap cause that?

Why would open flap cause that?

feck knows, but I have had it, and replacing flap cured issue.

[Das Chin]

yep spot on Lawsy. its not bad but its a little hesitation and then off she goes.

new flap motor actuator coming to rule that out.

going on diagnostics later in week to see if an O2 sensor has gone too.

That's the best place for it IMHO
