Civic of Doom: Honda Challenge Recycling

[Kaan]

SO... data said i was down on power. It was getting worse the longer i was out there... i'd see the same/similar corner speed but low Gs coming out, etc.

1. I sent my injectors out to get cleaned at Injector Pulse (great service by the way)
2. Injector Pulse said my gas smelled bad (i honestly thought this was my issue and my only issue)... so in addition to the cleaning i replaced my fuel filter and drained the tank (what a mess)
3. I made a date with the dyno... and boy i am glad i did.

On the dyno we discovered my TPS was failing.... the more heat the more issues (we only did 3 pulls on the dyno before the TPS was swapped). First pull looked like it wasnt going wide open (169hp) and i had a bad breakup at 7k rpms... second pull it showed the injectors (RDX) were cycling out (160hp) and it broke up again... third pull it was showing all of it (151hp)... we pulled a TPS off another car and threw it on... back up in the 180hp range... tweaked some things and go back to my normal 188ish hp range. My AIM Solo said i was only able to get 121mph on the front straight... which is about 8.5mph low... and i'm going to conclude the TPS was the reason (at least i hope so).

Several things are being swapped this winter... I'm going to put on my max bore throttle body, go up to a 3 inch exhaust, and i'm going to swap my RDX injectors out for something else. Some people like them, some people hate them... but the rule is... always do what your tuner says when you are looking for more and earlier power.
