running too rich

[Vpinto]

Hi Guys,

My TU5JP4 is running a bit rough since the installation of catcams 743 and with an intense smell of gasoline.


After some thougths, I´ve connected an AFR gauge, and when WOT the car is getting richer and richer until goes to "RICH", at about 5500 rpm.

Also,the wideband at idle and whenever I´m off throttle is showing "12.1~12.8".

Any thoughts were to begin?
Switched the ECU with a friend of mine, no joy.
Disconnected the lambda sensor, to see If anything happens, no joy.


Thanks in advance for your comments.

Perhaps you need the ecu remapped,to to get the best out of the cams and to get the fueling correct.
