My interest is in looking for smoother low-speed operation... i.e., get rid of the slight engine rpm surging and snatch, reduce the decel pop.. both likely caused by overly-lean A/F.
The Dynojet eliminators just send a constant voltage signal to the ECU... 0.45V???.. and do nor create any A/F enrichment. (That voltage results from a 14.57 mix...but who knows what the ECU is programmed to do in response to that??? 15's or worse??)
Theoretically, the AFX-IED can be adjusted to send a false voltage signal, thus persuading the ECU to feed in a bit more fuel... they claim attainable enrichment to maybe an actual 13.8.. which oughta be enough to fix what I want??
Anyways, Wadejesu has one in place and I'm looking forward to his further comments.
