Benchtop ECU question

[Barry Tisdale <btisdale@cybersol.com>]

Got a 7749 ECU hooked up on the bench & have a question.  This relates
specifically to SyTy PROMs, but its probably a general case.

When the PW gets small enough, the injector goes into Quasi-asynch mode -
this is readily hear-able as a halving of the injector pulsing.  Good so far.

On tweaking (opening quickly) the pot used for Throttle Position Sensor,
Accel Enrichment is heard in the injector as a brief doubling of the normal
rate, but only rarely seen in the ALDL data stream as ms. values.  Nothing
consistant here.  ????

Any feedback?  Thanks much - Barry
