If you are asking for a BIN then this thread will be deleted.

As it is running rich, not surprisingly, you need to reduce the VE tables until you can run the engine. Then do some data logging and use the BLM tables in WinALDL to further tune the VE tables. Then work on the spark.

Did you reset the BPC in that .bin for your injector size, fuel pressure, and CID ?
