E67 ECM Lambda

[Warren]

Does anyone no if the GM E67 ECM and run package will run 4 x lambda,i have it hooked up to a stock LS7 with 2 x lambda and need to try and get through a Euro 4 test with 4.

Euro 4 is a strict emmission test and is explained on wicki,I was hoping so to find out if the E67 ECM is capable of running all the systems for the test

Are you talking about pre-cat and post cat O2 sensors on each bank...?

I googled it and wiki has an article: http://en.wikipedia.org/wiki/European_emission_standards

so according to the table in the wiki, Euro 4 is a standard for the level of emissions...

if you tune the ECM correctly and rub closed loop you can achieve CO/NO/HC levels much lower than shown in that table for Euro 4...

i.e. from what I see/understand, the level of emissions is purely a function of the tune and how well it runs in CL.

Joecar correct 02 sensors before and after the cat on each bank,so the test includes checking all 4 working correctly,even is the emmisions are reading low the circuits have to test correctly ultimately can the E67 run do any of this
