I assume you used a transistor to switch the current into the injector?
To what voltage did you clamp the Drain or Collector of said transistor?
The reason I ask is if you clamped to say, 60V, the latency numbers will come out longer than the AEM which IIRC clamps to ~33V. This would explain why I need around ~900 uS with the AEM at 14V.
The reason for this is that the higher the clamp voltage, the quicker the current decays and the quicker the injectors close, lengthening the apparent opening latency time.
