    I agree, running rich. See attached screen shot BLM summary for log 3. Change the injector flow to a larger value to lean the entire VE table. I recommend increasing the injector flow by 1 lb. or 2 lb. increments. Once the VE table shows both lean and rich conditions, adjust the fuel tables (VE tables) both near idle and off idle for BLM averages of 128.

    One option is to use the Moates.net Burn 2 Chip Programmer (http://www.moates.net/burn2-chip-pro....html?cPath=64), G1 adapter, ZIF Socket, and 27SF512 Flash Chip. Another option would be the Moates.net Ostrich 2.0 (http://www.moates.net/ostrich-20-the....html?cPath=64). I like the Ostrich 2.0, because I can make changes real time, even when driving!

    You will need the G1 Adapter.
