Well heres the setup and situation

1994 b18b
Neukin equal lenghth
garrett T3t04e 57trim .63a/r
RC550 CC injectors
Walbro 255lph
Greddy type S
Tial 38mm
Hondata s200b tuned by whipfactory(one of the better tuners in the midwest)

anyways heres the problem

when normally driving around town not boosting at all ill get this hesitation...

ill try to explain it the best i can

usually under normal driving situations when you back out of the gas to slow down or something the engine will respond to the throttle the way it should and slowly lower its RPMs and everything is normal

in my situation... sometimes its normal but othertimes its just terrible

ill be slowing down for something and slowly pulling out of the throttle but instead of the engine slowing down nice and smooth it practically just jolts and it feels like the throttle snaps closed... but then i have to give it gas to get it out of the hesitation so i give it a bit of gas and it feels like the thorttle snaps open again.... the problem persists until it magically goes away.. no telling when no tell tale signs of when its gonna happen or not...

this is not a problem under boost but id figure id post it in here bc its only been doing this on the turbo setup...

It could be a minor problem in the part throttle tune or lack their of. If the car wasn't street tuned and only dyno tuned then you can't hit all the load points on the map. I would take it back to where you got it tuned and see if they will datalog it while your driving it on the street to see if thats the problem.

part throttle needs alil bit more work it seems.

JDM EJ1 95

it runs great most of the time its just sometimes ill start the car up a few hours later and go for a drive and the probelm arises out of nowhere

I am having the same problem. I think it comes from the weather changes and with hondata not having a iat correction is tends to mess with part throttle I think that is what my problem is.

JDM EJ1 95

yea it seems like exactly that...... bc its always different outside from when its not doing it to when it is

the hondata 2b versions notoriously had the "part throttle hesitation" your speaking about, from what I heard it was one of the bugs fixed in the version you have the s200's.

I would think some more part throttle tuning would probably clear it up.

if it was in the tune dont you think it would happen all the time though??? i mean it was tuned by a great tuner anyways..
