Had the car running sweet new lamdas, Apexi air filter trust greddy cat backs and now using vpower. Cat overheat light was coming on occasionally when booting it before air filter and lambda's done and all was good after were fitted. Fitted a mines ecu boosts harder and higher than before but cat light comes on briefly when in midrange for a while. It sort of has an uneven spot there which could be causing the prob of overfuel. When in power mode and raggin' it ... doesn't seem to come on. V. peed off anyone else similar probs

iff your mines is like mine which has a very rich fuel map then the cat overheat light normally comes on when it gets filled with unburnt fuel so you need to ask why is the fuel not getting burnt midrange allso the fact you fitted another ecu should,nt increase your boost values

It's gone about 1/2 a unit on the jap gauge 1 psi I guess in real money. Does your light come on regularly then? When it's in power mode it stays higher in the rev range, doesn't use the clutch so much and stay in the flat uneven spot so doesn't seem to happen. Wasn't happening with the stock ecu.

check fault codes

check fault codes

will get that done

Do your cat lights come on? I'm assuming your decatt is stock cat material inside pipes removed

also if its applicable no error codes on stock ecu came up

will get that done

no mine dont come on and yea i de-catted the originals,my first zed had your prob for months with no ill effects and i just ignored it till it got sold

think i'll just stick the stock ecu back on and flog the mines one. See how that goes.
