I know the techedge puts out a linear out singal in one of the outputs that are on the back of the techedge ecu for the sensor.. they read v3 v2 v1 rmp _ t3,t2,t1
I JUST DONT KNOW WITCH WIRE TO USE.. I have a hondata engine management system hooked and i know for a fact hondata hooked up a FJO wideband to there system and i dont see any differecne of if i hooked up a techedge..
Here is some information if helps ...
1) The V3 to V1 inputs log voltages in the range of 0 to 5 Volt (relative to GND).
2) The centre two pins are the GND (or EARTH = triangle symbol), and the RPM pulse input.
3) The T3 to T1 inputs connect to K-type thermocouples with all thermocouple returns connected to the GND point.

 

does any one know????????????????????

 

just get a wire diagram and look for the sensors you want.

The Tach sesing wire is probably the blue one from the coil. and you prolly wanna log mpa and tps. well they go from the sensor on the throttle body to the ecu. look at a wire diagram and get the colors. Just connect Ground to the car body. you dont need the thermo couples unless you want to log charge air temp.

 

bump, cuz i need to learn this as well, from what i've tried to retain thus far hondata has to get the WB signal between the box and the display. there are only 2 wires in the DB9 wire that the hondata needs to see. I'm prolly wrong so someone help us

 

i just want to hook up a O2 signal so i can run in colosed loop with a wideband

 

You are looking at the wrong connector. The one you want is the RJ-45 connector on the other side of the WB. You want this:

You want to connect pin 4 to the stock ECU O2 sensor voltage pin. This is explained in this link on Hondata's website: http://www.hondata.com/techwidebandtuning.html

This should get you going.

 

man, so the other side where the rj 45 goes is when the techedge ecu converts the wide band signal to a linear signal.. man that makes perfect sence.. so you are saying that the pin 4 is the place were i tap the honda ecu o2 signal... so i have to go to radio shack and by a rj 45 and make a lead for it... thanks alot

 

edited.

 

Instead of me running the wire to the socket of the o2 sensor, can i splice the o2 sensor wire on the ecu into pin number six on the Rj45 i think NBSIM stands for Narrow band simulation correct me if i am worng... and pin 4 is Wide band line in .. ?

NEVER MIND IT IS PIN 4 OPPS
