So you can see it's very important to start with a Boost Target table that has an accurate representation of what the turbo can actually do. | So you can see it's very important to start with a Boost Target table that has an accurate representation of what the turbo can actually do. | ||

- | You do that by making a good, long 1st, 2nd and 3rd gear pull with error correction disabled and starting at an RPM below where the turbo can build boost. So start at, say, 2500 RPM on a flat road in each gear and wind it out to, say, 7000 RPM at full throttle. Repeat for each gear and maybe do a couple pulls like that. You want as much data as you can. | + | You can get a good Boost Target starting point by making a long 1st, 2nd and 3rd gear pull with error correction disabled and starting at an RPM below where the turbo can build boost.

This function averages the boost pressure and duty cycle at each RPM point and in each gear found in the current datalog and copies that data into the Boost (WGS) tab. | + | With that datalog displayed, right click on the graph and select the "Set Boost (WGS) tables" helper function.
