TTS, SERT, etc. tuning question - Acceleration Enrichment
Based on the AFR spike at the beginning of WOT and dip at the end, this graph (TwinScan) seems to indicate I need to adjust the Acceleration Enrichment values, and maybe the Deceleration Enleanment. It is repeatable, to varying degrees, in other throttle positions and shows up on both the front and rear sensors.
Am I reading this correctly? Thanks in advance!

Add a little acceleration enrichment and try it again. The decell enleanment is for closed throttle. The lower the number,the more fuel it adds. It is used for decell popping.
The spike at the end of your graph is the fuel that backs up when the throttle plate is snapped shut from the sudden lack of air.not a big deal unless it causes a stumble.
