1G DSM Speed-Density!
| Speed density conversion
eliminates the MAF and instead uses a 3, 3.3, or 4 Bar MAP sensor and GM
IAT sensor for fuel and timing calculations. What does this do for
you? Timing maps now cover the entire boost range, and therefore
match the boost curve, rather than being fudged by RPM and having to be
retuned at different boost levels. Once a speed density car has
it's timing and fuel maps dialed in, boost can be turned up or down and
hte timing delivered will be correct without having to change the
tune. This also creates a more precise, accurate tune, that will
be more consistant from gear to gear, and through spool-up.

Why speed density? |
|
Requirements: |
| - Eliminate the MAF | - 1G EPROM ECU | |
| - GM IAT Sensor | ||
| - More accurate, precise, and safer tune | ||
| - changing boost no longer changes the tune! | - GM 3 Bar, GM 3.3 Bar, or "custom" 4 Bar MAP sensor | |
| - Increased response | ||
| - AEM Boost solenoid (for boost control) | ||
| - Take advantage of extra features not found in any other 1G EPROM solution |
