I'm doing some remote tuning through PMB for my injected 2056. The tune is close and I've been driving it but there are improvements that could be made now that I have had about a year and change since my last tuning session.
Eric suggested I move my O2 bung from the muffler (where I knew the location was not ideal but it got to sample all 4 cylinders) to one of the exchanger pipes (much better/hotter location, but only get to sample one cylinder.) Tapping into the Cylinder 1/2 bank would be easiest, and I was thinking of going into Cyl 1 since the pipe is shorter and maybe a little hotter. So now the question is what cylinder is the one I want to TIG weld the bung into. I don't track EGT so I don't really know if one pipe is hotter then another. And I want to eventually get heat back in my car so I can't go to headers which would allow me to sample all the cylinders before the muffler. Thanks! Zach @Eric_Shea |

NP at all. (IMG:style_emoticons/default/agree.gif) I don't know of a decent solution at this time though, short of using two O2 sensors. I'm very interested in this thread at this point in time.

NP at all. (IMG:style_emoticons/default/agree.gif) I don't know of a decent solution at this time though, short of using two O2 sensors. I'm very interested in this thread at this point in time. I had two wide band meters on my /6 with carbs, I'm done tuning and one is off the car now. If anything I found it confusing and ended up only looking at the one meter at a time. Basically they read the same and if your engine is sound they should all be the same. Since I have carbs and I don't really like the look I'll likely remove the other meter as well. If you're carbs, L-jet or D-jet there's no real reason to leave it on after tuning. Aftermarket EFI leaving the WB installed depends on if you run open or closed loop. |
