Delay after depressing throttle.....possible causes? (uber w/pr4)
 

What would be the most likely cause of a large delay after pressing the throttle? At first I thought it to be a timing issue but it seems that may not be the case. I recently swapped engines and went from an underhood intercooler to front mount. The engines were both b20a's (3rd gen prelude)
I'm running uberdata with a chipped pr4. The same map that worked on the other engine doesn't seem to be working on this one. If I slowly depress the throttle the engine responds ok but anything moderately quick makes it want to bog way down before the rpm's rise. Sometimes it nearly stalls.
Any ideas?

Sounds like your TPS 'Tip-In' is going lean...common problem I remember I used to see with Uberdata.

There might be a fix...

Thanks for the advice. I enrichened the tps tip-in and the majority of the hesitation is gone!
You saved me a lot of hassle. Thanks Xenocron

Problem is Uberdata cuts fuel at TPS values less than 15, stock TPS closed position is 9 or sometimes 10. I adjust TPS to 14, never worry about fuel cut value.

yeah sometimes in uber i feel hesistation on deceleration, and my tps or throttle sticks at like 10%?wtf

It's not %. It's arbitrary junk number. "10" is about right for stock unadjusted TPS when closed.
