| - | These values were gathered from various sources. These may not match exactly with the values specified in the DSMLink user's manual. Regardless of which set of values you start with for your injectors, you will still want to run through the dial in procedure outlined in the DSMLink user's manual. | + | These values were gathered from various sources. These may not match exactly with the values you've seen elsewhere, but they should be fairly close. The problem is that each injector can behave a little differently from another of the same size and manufacturer. So there's some variation that simply can't be accounted for in all cases. Start with the values listed below and fine tune from there. |
| - | All of these values assume stock base fuel pressure (37psi for 1Gs and 43.5 for 2Gs). | + | All of these values assume stock base fuel pressure (37psi for 1Gs and 43.5 for 2Gs). Deadtime is listed as an adjustment to be entered into the ECMLink application, which is then applied on top of the calculated stock adjustment. |

| - | These values are for **GASOLINE ONLY** - they do NOT apply to cars running E85! E85 has a stoichiometric A/F of 9.8526:1 while gasoline is 14.7:1. So E85 should require around 49% more fuel than gasoline (14.7 / 9.8526 = 1.49). So for 850s (as in my car) with pure E85, I would run: | + | |
