how-to: control closed loop AFR with your wideband O2 system
#46
The LC-1 was so easy to setup for this....not sure why the ZT2 is being such a bear! I guess try it on your car and share what you find, maybe I am doing something wrong? but i have checked and double checked......always a triple check I guess!

maybe I will try your old patch and see if it works?.....
I just cant imagine the calcs. not being right, when logging the stock O2 with analog/serial they both show 14.7ish driving around..

Its probably the patch. I tested it in the simulator, but not on my own car. Sometimes the simulator doesn't do things exactly as the processor does. I give it a try on my drive home this evening.

Thanks - I just re-did the old patch, going to try it on my way home from work. I def. know it works because I used it for a good while, the LC-1 hiccups is the only reason I stopped using it.

By chance did you try re-doing the current patch? I had to go back through the steps for direct boost after hating myself for weeks trying to figure something out, and of course I missed copying one value that screwed it all up!

Ok so I have edited the new patch to my .xml file and transferred over all of the values from the rom given by mrfred (edited tonight w/ new revision), but when I open up "cold engine closed loop afr" my value is "..." is this a scaling issue? The reason why I ask is when I click "edit map" I have "none" for scaling. I looked @ the patch for the .xml and scaling was "AFR16" but there is no "AFR16" there is only AFR. I have tried changing it to AFR and it still read "..."
I am having a ZT-2 w/ LCD installed on Mon. and I wanna makes sure I have my ish together! any ideas?
TIA

Well I made another attempt at using this new patch vs. the old patch and I am still having problems. The car fires and idles but the afr is 16-17 no matter what is in the map....I go back to the old version and it works like a charm?
Mrfred any ideas what could be causing this? have you tried it on your car yet?
