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...

Try raising the TPS component up to 100 and then 200 and see what changes.
and try dropping the duration of it if it gets too rich after the initial adjustment.
