Changes

WARNING...DO NOT ADJUST ANY OF THE TIMING VALUES IN THE COLUMNS BELOW 1000MG/STROKE. Why? Daily driving around town from stoplight to stoplight the engine uses ignition timing fairly aggressively due to the lack of airmass (which is due to the lack of exhaust volume spinning the turbine) to power the vehicle. If you lower these values the car will feel sluggish at part throttle. If you increase these values the engine will knock. Only make changes to the last few columns of the tables. Once you get comfortable with tuning and are looking to move to more advanced manipulation (i.e bigger turbo, E85 blend timing, etc..) you may feel the need to increase or decrease values in some of the air mass columns in the 600-900 range. For larger framed/slow spooling turbos you may need to increase timing at low air mass to remove the off/on feeling. Winter gas blends often have less knock resistance that can often lead to excess low air mass/spool knock that one may seek to reduce without also reducing overall timing by adjusting the slider. Use your datalogs to make adjustments as needed. If you are consistently seeing knock in a few cylinders at a specific RPM range then adjust the timing down at that RPM and air mass cell. It's best to make timing adjustments to both tables equally (or as equal as possible). If you are going to pull 1 degree of timing out at 6000 rpm in the 1299 air mass column then pull 0.375 from one and 0.75 from the other. If you feel like you need further reductions then pull more from the table that got the 0.375 reduction. If you only adjust one table then your octane sliders will no longer function smoothly as one end gets aggressive quickly and the other doesn't respond adequately.
