Title: ME7.1.1 Lambda Bank Selection Post by: ported2flow on October 31, 2012, 06:54:02 PM hi
im trying to set up the Lambda Banks on Me7.1.1 for example r32 it comes with 2 banks original trying to set it to 1 bank selection.usually CWKONLS is set to bit 51 and i set it to 3 but in the measuring blocks i still shows 4 lambdas. any hints? thanks Title: Re: ME7.1.1 Lambda Bank Selection Post by: jooo on October 31, 2012, 09:46:05 PM hi Hello Ported! :)im trying to set up the Lambda Banks on Me7.1.1 for example r32 it comes with 2 banks original trying to set it to 1 bank selection.usually CWKONLS is set to bit 51 and i set it to 3 but in the measuring blocks i still shows 4 lambdas. any hints? thanks I'm quite certain it's a system constant from compilation at the factory SY STERVK PROKON EIN system constant condition: stereo exhaust system upstream of cat Simple solution might be to make sure in code that lamsoni_w also get written lamsoni2_w memory position. Though I have not checked the FR yet if that is the correct variable and if it is as easy as this. That way you would only need 1 pre cat lamda in downpipe. Perhaps that is what c2 used to do to solve the situation for all complaining eiptuining vr6 24v customers a few years back. But you need to startup IDA to fix this. preparing for a tubular manifold with no possibility for stereo lambda pre turbo?

:D ill check mails Title: Re: ME7.1.1 Lambda Bank Selection Post by: Snow Trooper on November 01, 2012, 11:59:54 AM Us single turbo 2.7t guys have been messing with this for a while, so far a solution has not been found other then to run o2 pre turbo. I will investigate the lamsoni_1 idea.

I will investigate the lamsoni_1 idea. We don't have lamsoni as we have narrowband ECU's and this is lambda actual. It actually should be easy to solve in the same way that I did my EGT's from a single sensor. Title: Re: ME7.1.1 Lambda Bank Selection Post by: prj on November 01, 2012, 05:02:46 PM It can be solved at the point where the second O2 voltage is read.
Just NOP it out and copy over the first O2 voltage instead, job done. Title: Re: ME7.1.1 Lambda Bank Selection Post by: jooo on November 01, 2012, 05:40:01 PM After some FR reading I've come to the conclusion that UULSUV_W seems more correct than lamsoni_w. Still, this only apply to wideband ECU's.
