Would somebody be so kind as to take a look at the attached and let me know where I need to focus my attention?
This is a log of stomping on the throttle at idle. Initial AFR looks ok to me, but then there's a huge lean spike half a second later. I'm attempting to crispen up throttle response as hell and toe is very laggy right now. It feels like the motor sucks air for a split second before reacting, making rev matching a guessing game.
Thanks for any input.

can you post up a screencap of your enrichments? both the main page and the asynch pop-up.
ideally, you could raise the 1000 rpm asynchronous pulse by, say, 30% and it would take care of it, but I suspect it's going to go quite rich from then on. I'm guessing you have to set the duration of the TPS / MAP component to a smaller value. somewhere between 200 and 400 ms I'd imagine. Then see how smooth the AFR stays. if it's spike-free but just too rich for longer than a spike, lower the TPS/MAP components some...
