Here's the file. See Brian's set up in his sig. Car surges at idle, and obviously the ecm is confused about things. You can see the surging idle at the tail end of the file, where the rpm and timing keep jumping around. There's another spot where this happens, we had just pulled into a parking lot and were idling along, I think this was around the 340-350 sec mark. It's weird - BLMs just hit the floor, most going down to 90, so it is obviously pulling fuel out, but then sitting there at idle it just goes dead lean. It's a puzzler. One thing I did notice is that the 3rd gear/4th gear switch isn't working, it thinks it is in 4th gear all the time.
I've got more files, where we changed the setting in the Gen2 to the Extender setting, and where we lowered the fuel pressure, if anyone wants to see those too.
