34 Error?

I change my turbo and install a new FFIM, and I can't run at WOT because the A/F drop below 10.0. I check my engine codes and display the Devil 31 (I'll rewire those cables and see if the error fix it), and the new one 34!.

For the 31 it’s a problem that only affect at Idle, but the 34! :aigo: I don’t now how can I fix it :cry:

Any Idea will be grate!

Thank you all and please help me. :1zhelp:

I have a Lex AFM.

I was thinking in Fuel cut, but it happen even with 8psi of boost

Then id say its a boost leak. Code 34 is all you get?

Carlos, its due to the fact that you are running a larger turbo now. 8psi on the new turbo is like 14psi on a stock ct26.

fuel cut at 8psi?

 

[MDCmotorsports]

Its NOT THE PSI THAT MATTERS GUYS. ITS ALL ABOUT THE FLOW

 

[supramike7m]

i know, but that must be a huge turbo, to hit fuel cut at 8psi and with a lexus afm

That and Carlos has boost leaks......

I found few air leaks :cry: I hope I can fix by tomorrow..

And suppost that with the Lex AFM I can boost to 22psi more or less right?

 

[supramike7m]

no not that high, especially with a larger turbo
