My 2007 S hangs on to revs for a long time between shifts - If this product will improve that issue, I will buy it

 

Looks to me just like a signal booster - i.e. you push the pedal an inch, it tells the TPS you're pushing it two inches, thus exaggerated (relative to OEM) response to pedal movement.
Doesn't seem like it would to anything to help the revs drop between shifts. IMO, of course.

 

Thanks Eric - Just like an upgrade on the "sports button"?

 

The Civic SI had this same issue when it came out - Honda fixed it with a free ECU reflash - Is it just me, or does this driveability issue bother anyone else?

 

lol, like a sport button. These things are very unnecessary.
