Accel Enrich - Flat spot

Meh, I can only do so much searching. Question, if I touch the gas, response it pretty good, if I jump to half throttle, initial response is good but then it hits a flat spot for a couple of seconds then 'catches' and goes. So, I think I'd look in the MAP PW Multiplier vs MAP table (@ 0580). Do these MAP values 0 - 50 correspond to change in MAP, or just MAP? How would you go about figuring out where more or less fuel needs added. What should WB reading be when you step on the gas, in the neighborhood (10, 11, 12.x:1)?

Thanks for the help.

The table at $580 is based on delta MAP. You need to check the data log and see what is happening. It may be too much AE which drives the INT & BLM down. Then as the AE runs out the engine is left lean.

Port AE is touchy, need just the right amount. And if running closed loop less is better.

Locked BLM/learn disabled. I'll look more closely at the log.
