I also welded a wideband sensor into my Bursch. It's very helpful for tuning. You can really dial in the MPS with the AFR and get it right in the range you want. I do not have any issues with idle data sensing and capture. I put it basically in the same spot as you did.
My original gauge and kit was a Chinese knockoff... AEM kit. It worked fine... except when I went to wire in an RS232 so I could log data to my laptop... it wouldn't work. So I bought the real AEM kit... and only had to change out the gauge... all the wiring etc is the same. It works perfectly and now I can stream data onto my laptop easily. I also have a 123 + distributor... with Blue tooth. This version of the 123 will create a log file... which I simultaneously log along with the AFR/OS data. Post run.... I bring it all into spreadsheets and can graphically view that data. The data elements of advance, vacuum, rpm, speed, temp, AFR, etc... allow you to view engine load conditions and how the Air/fuel is changing... A few tweaks on the MPS... and you can really see whats happening... improvements and compromises along the range. I'm planning to write some Python code to simplify the process and get it all to not only log but crate a viewer realtime. |
