Is it more acurate to hook it up to the ecu or the O2 sensor, for a 95 integra?

Hook it to the o2 senser

reddevil94

o2 bro, that is where is needs to hook up to...

Greaser

it doesnt matter where the connetion is made, at the 02 or at the 02 input on the ecu.

get another bung welded in and run a GM one wire O2. You'll get better readings this way.

if you get a one wire o2 sensor, how do u power it to get the readings?

WS6

what? power the O2?

Greaser

you dont power a 1 wire, it doesnt need power. once the sensor heats up it gives readings.

Those 3 and 4 wire sensors.......the extra wires are to power the HEATER that heats up the sensor element.

Greaser

no you wont, an unheated sensor in no way is more accurate than any factory heated sensor.

inaccuracy during warm up and then inaccuracy during full throttle vs coasting/part throttle driving.

sure it'll give you a good idea, but get a heated sensor at least.
