I am totally stumped ont his one.. All i can think of is it is some bug in Hondata.
When i first got my car tuned, everything ran great, then a few months don't he road my CEL comes on and the car starts idling weird. Of course it was TP sensor. But what was weird was, when i was driving there was no CEL, but the the car would just fall on its face for a second or two and then it would jerk and start running fine again except it would through TPS code. The weirdest part was if i floored the gas while it bogged, when the car would jerk back on it wouldnt through TPS, but if i didn't floor it, it would come through TPS. I had an extra TPS laying around so i swapped them, calibrated the new sensor and everything was great. well now 4 months down the road its doing the same exact thing. I checked everything i can think of...
closed throttle = .55
open throttle = 4.5
+ and - on plug = .5

the reason closed throttle is .55 b/c it helps smooth out low end throttle response. I know people who do it and never have a problem so i don't think its that. Plus i didn't have that done last time it happened, it was a stock TB.
Why is open throttle .5 to high? does that mean the TPS is bad? I wouldnt think so since 4v is just an approximate.
The only other thing i can think of is Hondata but why would it only happen after a few months?
Is it just plain bad luck?
any ideas would be much appreciated!!!!

We always recommend that at idle the TPS be adjusted to .49.

You may have a wiring fault in the car that is only happening at a certain resonance frequency and thus you get the problem at a certain RPM.
