Thanks Tony. I'm pleased to know that it's appreciated. I feel I still need to cover a lot more of these because I don't fully have a handle on all the subtleties of lambda control. Best endeavours though...

yup thanks for all the hard work Doug

Bump.

LRSHK 9.20 (Continuous Post-Catalyst Lambda Control) added 10th January 2012 and on the Nefmoto wiki to assist with understanding the integration of both pre- and post-cat lambda control if experiencing a malfunction on either system.

Hey, TTQS!

Are there any chapters dealing with Post cat o2 sensor heating? I've disabled post o2 correction, now my front sensor doesn't jerk around, but I still have limp (with zeroed out P1114 and P1118 from error class table). When I plug in my post cat o2 sensor (with fouler) I have no problems, but if I disconnect it I get limp. There has to be something with the heating of o2 sensor... Could there be situation like this: ECU checks o2, finds that it is disconnected sets LIMP and only then stores P1114; P1118 errors? So basically If I zero out error classes they are only not saved in memory, but the check is still performed?

Maybe you could tell me what does CODEWORD TESTER MAP? I have found it in my bin but it has have weird value of decimal 14

Also in funktionsrahmen there are always used CARB error codewords. I have never found them anywhere in my bin. Do they exist?

I'm thinking just to shortconnect this function by setting TADHMN very high... What do you think?

BTW: CWDLSU and CWKONFLS are very interesting. Looks like they deal with postcat o2 sensor but I don't know their possible values

This should be in another thread, but you have zeroed CDHSH and CDHSHE?

So rear O2's plugged in and everything's good, rear O2's unplugged = limp mode?
