Would like to be able to get it to run right without it dumping tons of fuel. Plug a stock injection timing table into the spreadsheet - might realize some things Factory targets PPV at idle and low rpms - they only start advancing it at cruise and higher rpms and stock actually has the ability to inject as the intake valve is closing with high enough Servicing and repairing foreign vehicles is straightforward if you have the proper knowledge and experience. Follow along with lead instructor, Jeff Evans, as he walks you through how the fuel injection timing is calculated within the Gen IV ECMs, and what changes need to be made when upgrading the I am thankful a few guys using HP Tuners figured out how it all works and created formulas in the form of an Excel Spreadsheet.
