I have a wideband connected to a gauge on my dash and I've noticed that my A/F goes very lean upon sudden application of throttle, within a second or so it will normalize. Old carbureted engines had an accelerator pump that provided a burst of fuel in these conditions and GM ECMs have a table called "acceleration enrichment" just for this purpose.

Does the Honda ECM have something similar? It's a P28 ECM. I was looking in Crome for it but didn't find anything.

 

TPS tip in enrichment.

 

Is that in Crome? Did I just miss it

 

It has to have a tps tip in enrichment option. I haven't used crome in a very long time so I can't tell you where that option is located in the software.
