Hy Guys

I hope you can help me because i'm driving crazy with my Evo 6.

Problem is when the car idle's and when you holding it on 2500rpm i don't get Lambda 1. The Evo is running too rich wirh lambda 0,7-0,8. So i don't pass the emission Test.

Facts on the Car:

Standard Exhaust and Airbox no mapping or other things.

Things we have done

New denso lambda sensor
Changed the injectors
New plugs new coils and leads,new filter and new fuel pump.
Changed maf sensor,water temp sensor. Cheked for boost leaks. Tps is running on 13,3 volt. Changed the ecu.

All nothing.

 

Do you have a Tactrix cable to datalog? Sounds like your car is stuck in open loop.
