I'm fiddling with passing emissions and I'm seeing a large rich spike whenever I lift to shift. Large enough to fail the emissions test even though I am very well sorted to 1.0 lambda in most conditions. Could this be cause by the dumn air-jacket injectors? I have blocked off their air nipples. Currently I do not have all of the kit necessary to install the original air jacket system.
Log file. Stop sign. Drive one block in city. Stop light. Drive a couple blocks. stop. etc.

I should note that I tuned this at a humid 55 degrees and the weather is now very dry 100 degrees most of the time. This log is from the morning when it was cooler, but still.
Your tune suffers from lot of problems. I would say you have to start from beginning. MAT/TPS enrichment table is wrong - it is base for proper fueling when air temperature changes. And VE table is untuned at all.
You have to start again with proper MAT/TPS table, valid injector characteristics (latency) and from that point start to construct valid VE table.
Also take proper attention to injection angle. If IGN an INJ tables lines matches, your angle is very bad. Also line must be even. Tune it for best throttle response from idle.

really? I think I got this tune from member that you tuned? I carefully checked the injector instructions as well.
I found what the MAT/TPS should look like in a default config - WOW! Different. I'm still confused on injector angle. I thought I had read everything and followed instructions.
thanks!
