Tuning '94 chev Suburban Big Block

Dave:

Thanks again for the assistance. Don't understand the statement "It's a good plan to use closed loop data". Please expand on the statement please. Thanks.

Closed loop is when the computer takes full control of both fuel and spark based on the information from the sensors (Knock, TPS, O2, MAP, RPM, & CTS). Tune using only the data that was recorded when the computer was in closed loop.

Dave: Did exactly that with a BJKW 0E altered binary and the Suburban is running fairly well. In the process of using your spreadsheet and BLM data to correct the BJKW binary. Looks to be a VERY good method/process. Again, thanks for all your assistance.
