[Diy_efi] Hesitation

[Mike]

Any transient mixture enrichment on rate of change of throttle position ?

Even the oldie hitachi/bosch ecu reads rate of change of throttle
position and intersperses extra injection pulses to act like the
old accelerator pump of the carbie days, seems like you have
that issue from your description as you report its more than
noticable when on load - that is when its most apparent...
