| 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 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.

| - | Note how each gear builds full boost later in the RPM band. And notice how this particular example shows some boost spike just as full boost is built. You can either keep that spike in the curve or try to dial it out using lower duty cycle values and lower boost target values. | + | Note how each gear builds full boost at different areas of the RPM band. And notice how this particular example shows some boost spike just as full boost is built. You can either keep that spike in the curve or try to dial it out using lower duty cycle values and lower boost target values. I personally like this spike, so I run it that way on purpose. I want to get as much as I can from my turbo. So building more boost early on in the RPM band (where my turbo actually can build boost) is one way to do that. |
