| - | First, the basic process of adjusting DSMLink for different injectors is simple. You simply use the ECU->Fuel dialog to adjust the global fuel slider and deadtime value. The [[baseinjectordata|Injector Data Compilation]] page contains a handy list of starting points to use. The DSMLink user's manual also includes a large section on injector compensation. If you haven't already read that, **please** do so now. It contains a lot of information I just don't want to repeat here, like how to adjust those basic global fuel slider values for non-stock base fuel pressure. | + | First, the basic process of adjusting DSMLink for different injectors is simple.

| Once you've made this basic adjustment, you can fine tune from there by watching fuel trims (LTFT) while idling and cruising. Again, the user's guide provides details on this process. Once idle and cruise are about where you want it, you can then focus on wide open throttle tuning by watching measured A/F ratio using a wideband and comparing against the estimated A/F Ratio provided by DSMLink. More details on the estimated A/F Ratio item can be found on the [[afratioitem|Estimated A/F Ratio]] page. | Once you've made this basic adjustment, you can fine tune from there by watching fuel trims (LTFT) while idling and cruising.

| None really, because the current V2 1G offering uses a memory board to permanently record the changes you make via the application. So even if you remove that 1G memory board and set it on your shelf for 10 years, it should still power up in an ECU with the same settings it had in it when it was removed. So there is no need for a new chip with new default settings in a 1G. | None really, because the current V2 1G offering uses a memory board to permanently record the changes you make via the application.
