AEM uses the latest wideband sensor - require minimal warmup - like 5 seconds so it can be used to set up cold start.
I've checked the digital innovate and aem against a reference (lab quality) wideband. AEM is faster and a bit more accurate. The digital innovate is a close 2nd.
Cruise - aim for 15:1
WOT - aim for 12.8 to 12.9:1
Tune for part throttle cruise with jet size. Then adjust the PVCR to get WOT.
A 9.5" PV will bring in WOT enrichment sooner - down side is your mileage will suffer.
If your pull 2" of vac @ WOT and the sec. throttle blades are 100% open. The carb is too small.
