| + | ===== Approach 1: Just disable error correction ===== | ||
| + | By far, the easiest approach to dialing in the boost tables is to simply disable error correction. When you do that, you can ignore the Boost Target table entirely and just tweak the Base Duty Cycle to get about what you want. In fact, doing this is the starting point for setting up the boost target table for use with error correction. | ||

| - | Set the base duty cycle table to 0% across the board. You can do this by selecting all the cells in the table at once and then using the Ctrl+down arrow key combination to run all the cells down to 0%. | ||
| - | Go make a pull and confirm that you're getting wastegate pressure (probably around 10-15psi depending on the wastegate). You may find that you get some boost creep towards the end of the pull. That's usually fine too. You're just looking to see the minimum amount of boost you can achieve with your current setup. | + | Set the base duty cycle table to 0% across the board.

| - | Now, try increasing the base duty cycle table a bit and see that you can build more boost as the duty cycle values go up. Try setting all the cells to 50%, then 65%, then 80%, etc. You *should* see boost increase as the duty cycle increases. If it does, great...you have everything installed correctly and your system is working in a predictable manner. If not, review the [[bcsinstall|install page]] to see if you can find what's wrong. | ||
