FrankenCIS control algorithm runs between 1000 and 3000 times a second (1-3 kHz)
both the eWUR and Frequency valve operate at 100 cycles per second (100 Hz) and the CIS-E DPR cycles at 30Khz

at 6000 rpm we have 100 revolutions per second (6000/60) meaning between 3 and 10 mixture adjustments per ignition event

plenty fast enough

now the real question is does the system react fast enough? and from the VE/AFR logs it seems the answer is yes
VE commanded AFR of 19.8 to AFR of 10.2 in 0.3 of a second
1981 928S 4.7 ROW with KE3-Jetronic and Franken8 (AEM Inifinty) follow at []
Yes! mechanical/hydraulic constant flow injection can be managed by a modern EMS
