I'm just saying thats a safe guideline but you should be able to use a 50 shot just fine

[EXcoupe06123]

Yeah a might run a 55 shot some people says that zex give less of what they say so I maight be fine

Hey guys some one please post a DIY

Yeah it seems pretty easy maybe I will isntalit my self with some mechanic friend.

Just I am courious on how is the wiring to the TPS

Engine Speed (Tach) Connection
ECM Connector A, Pin 28 (Outputs Engine Speed Pulse (NEP)) --> BLU Wire --> Connector D, Pin 3 (BLU (NEP)) on the EPS Control Unit (located inside the cabin behind the kick panel on the passenger's side)

Vehicle Speed Connection
ECM Connector A, Pin 29 (Sends vehicle speed sensor signal) --> BLU Wire --> Connector C201, Pin 4 (on the 2006 Si) or Connector C202, Pin 10 (on the 2 door 2007 Si) --> BLU Wire --> Connector G, Pin 5 on the Under-dash Junction Box (located inside the cabin under the dash on the driver's side)--> Out of the Under-dash Junction Box via a BLU Wire coming out from Connector E, Pin 2 and a BLU Wire coming out from Connector D, Pin 2

Throttle Position Sensor
Throttle Position Sensor/Throttle Actuator (on the throttle body), Pin 1 --> RED/BLK Wire --> ECM Connector C, Pin 20 (Sensor Input (TPSA): Detects Throttle Position Sensor A Signal)...ECM does not output.

Throttle Position Sensor/Throttle Actuator (on the throttle body), Pin 3 --> RED/BLU Wire --> ECM Connector C, Pin 21 (Sensor Input (TPSB): Detects Throttle Position Sensor B Signal)...ECM does not output.

TPSA measures ~3.9V with the throttle fully open and ~0.9V with the throttle fully closed

TPSB measures ~4.1V with the throttle fully open and ~1.7V with the throttle fully closed

Great Thanks. But does this also aplies to R18's

From what i have gathered yes ill find out.

only thing that you really have to do is get another HP fuel line and "T" in to it to the ur fuel then connect to a wire on the back of the TB


i know its not detailed or anything but its not hard

HELP

Black wire ground, white is activation is the TPS sensor switch, the red is you arming it needs power 12v and a switch to interupt it.
And the nozzle is easy just put it no more than 8inch away from the TB
