Ah, thank you very much! Now it all makes sense. Looks like I have only 1 extra input on the ECU for what I want to do. Between wideband, boost, and EGT, I think wideband would be the most important to me.
After some looking I've found that the MMCD logging software has settings to convert the EGRT input to display readings for various MAP sensors or a wideband input (similar to how DSMLink does it). So, it looks like I'll be logging with MMCD and adding the wideband output from Zt-2 to the logs. Not a perfect solution, but it works for what I want to do.
I'm really excited to start tuning with the Ostrich. I'm going to start out by modifying the e931 Eprom code using TunerPro. Then I might move on to a speed density setup so I can eliminate the MAF. has pioneered a cheap speed density setup using the ostrich. Its basically uses a Map sensor and IAT sensor instead of the MAF, similar how AEM is setup.
Once I get going and have some results I'll gladly share them here.
