On the injector dead time, my question right now is "what should it be?" I have it set for a fairly standard 1 msec. These are the newer style smaller injectors with an EV14 connector. Some initial digging indicates that maybe it should be shorter than that (0.6-0.8 ms
That said, I think I have found much of the AF
issue. Too much accel enrichment and not enough decel enleanment. The AE is done in terms of ms
and the new injectors provide a LOT more fuel (600cc vs ~300) in a ms
than the old ones.
Before the AE/DE change the engine would often want to stall when I put the clutch in. The AF
gauge would go way rich as RPMs drooped very low/stall. If I coasted down in gear and let the AF
gauge read lean (16+), then the engine wouldn't stall.
Since the AE/DE change the engine always drops nicely to the idle RPM and stays there and the AF
is about right on the money.
I am putting a little more enrichment back in because I started getting a lean stumble on launch and throttle tip in.
