Acceleration Enrichment (Transient Fuel)
Acceleration Enrichment can be derived from two tables.
- RPM Acceleration Enrichment, RPM vs Enrichment PW vs Decay Time.
- TPSaccel Enrichment Scalar, TPSaccel (dv/dt) vs Scalar%
Transient fuel is the output of the RPM Acceleration Enrichment table * TPSaccel Enrichment Scalar.
Pulse width enrichment time
RPM Acceleration Enrichment
RPM | Enrichment PW | Decay Start |
RPM3 | et3 ms | ds3 ms |
RPM2 | et2 ms | ds2 ms |
RPM1 | et1 ms | ds1 ms |
RPM0 | et0 ms | ds0 ms |
TPSaccel Enrichment Scalar
TPSaccel | Scaling |
dv/dt2 | as2 % |
dv/dt1 | as1 % |
dv/dt0 | as0 % |
So with With the following entry:
RPM | Enrichment Time | Decay Start |
5500 | 4.4 | 0.8 |
4000 | 4.1 | 0.8 |
TPSaccel | Scaling |
50 | 100% |
25 | 65% |
Accelleration from 4500rpm with a TPSaccel of 35 would give:
RPM Enrichment of 4.2mS decay start 0.8ms
Scaled Enrichment 4.2mS * 0.79 = 3.318ms decay start 0.8ms * 0.79 = 0.632ms
