-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. ​ 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.  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.
  
 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. ​ 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.
