Running an AEM Series 2 EMS. The cas disc having 24 teeth instead of 4 gives a 6 times increase in timing resolution. This gives much better transient response, especially at idle with my cams (Crower 288/292).

Fail safe is the AEM failsafe gauge with flow meter, and I hope to have it triggering a boost dump and possibly ignition cut and/or fuel richening.

Staged setup was indeed for idle and also for cruise. With the 1450cc injectors, at idle my command pulse was half of the deadtime value. Previously I could get it to idle no lower than 1000rpm, and from my few minutes of testing so far I've been able to idle successfully at 750rpm.
