| - | ====== Injector Data Compilation ====== | ||
| - | |||
| - | 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. | ||
| - | |||
| - | All of these values assume stock base fuel pressure (37psi for 1Gs and 43.5 for 2Gs). | ||
| - | |||
| - | **NOTE**: These values are for **GASOLINE ONLY** - they do NOT apply to cars running E85! | ||
| - | The formula to calculate the correct global setting for E85 is: | ||
| - | Stock Injector size/(New Injector size/((percentage of E85*0.33)+1))-1 | ||
| - | |||
| - | **NOTE**: The E85 correction above may work for some, but it does not work for me. E85 has a stoichiometric A/F of 9.765:1 while gasoline is 14.7:1. So E85 should require around 50% more fuel that gasoline. That would make the formula more like: | ||
| - | |||
| - | Stock Injector Size / (New Injector Size / ( ( percentage of E85 * 0.5 ) + 1 )) - 1 | ||
| - | |||
| - | So for 850s (as in my car) with pure E85, I would run: | ||
| - | | ||
| - | 450 / ( 850 / ( ( 1.0 * 0.5) + 1 ) ) -1 = 450 / ( 850 / 1.5 ) - 1 = 450 / 567 - 1 = -0.206 or -20.6% | ||
| - | |||
| - | Using that formula works perfectly on my car. | ||
