Max Enrich Asynch Pulse Width

......... Every bin I have looked at has this constant set at 5.55msec ... Is there a maximum value that this can be set to without inducing other headaches ? ......... My tip-in AE is still weak on the Wide band with the Accel enrich %BPW factor vs asynch pulse width set at over 4.00 ..... I'm wondering if the Max AEPW is holding back the pump shot ? ..........

Re: Max Enrich Asynch Pulse Width

Hard to say. Looked at the code but it is convoluted in that area. If the async AE is run every 6.25 msec then that setting of 5.55 msec is about max. As the injector compensations are added to the AE PW after the max values is checked.

If the async AE is run every 12.5 msecs, then it can be increased.

Re: Max Enrich Asynch Pulse Width

Try increasing the max async AE PW parameter. See if it gets richer. If so then it may be the 12.5 msec loop.
