TroubleLS

everyone tells me i need to T off the fuel pressure regulator .. im running a 1990 integra there is no nipple to T off ... any other place i can put vacuum lines at ? i have a aem fuel rail with a fpr just don't wana throw it on the motor till i have a base tune and im not 100% on what injectors are on them....also just got the wide-band i have a bong for it.... but do i tie in the old 02 sensor wire in with the new bosch sensor ? and the rest connects to the a/f controller ? a little lost here but feel like im close to starting her up

you buy the nipple and cut the vacuum hose and then t-off of that.

you need to install all the parts first before you tune

the wideband is a seperate o2 sensor. it is an aditional o2 sensor on your exhaust. you should have the stock o2 sensor and then install the wideband o2 sensor with the supplied bung. do not mess with the o2 sensor wiring.

yeah my pipes are all cut n connected im just worried about the wideband i'll t everything up to the vacuum line behind the intake manifold ... but how am i hooking up this wideband ? so i spice the wire from the stock ecu wire to the new sensor ?

busa4

no. the wideband o2 sensor needs its own controller. your ecm cannot read a wideband o2 sensor so you cant splice it in.

your wideband o2 sensor should have come with a controller of some sort. weather its a box or a gauge.

TroubleLS

yeah so it's a stand alone ? im not hooking up my stock o2 sensor theres no place for it and it's gone ( it fell out the harness).. so onlything i spice in for the wideband is the power ground and illumination ?
how can i data log then ? thought it had it be hooked up to the ecu somwhere ... sorry for bein a pain in the *** noob

TroubleLS

can i t off the map sensor ? ? would it be ok if i hooked up the blow off valve to the nipple on the throttle body ? ? ? i know all the vacuum lines suck... but how much suck do i need and how small should the vacuum lines be >? if it don't rain tomarow ima think of where im puttin my battery and start her up =) apreciate all the help and knowledge

yes. its a stand alone. your computer doesnt read it. if you want to datalog you will need a controller that can data log. look into the innovate wideband or find a wideband gauge that can datalog. the wideband controller(gauge or box) has three main wires. power, ground and illumination. check to see if your wideband gauge has an analog/digital output. this can be use as an o2 signal to your stock ecm.

you need your stock computer to read an o2 sensor. without it the computer stays in open loop. those cars are a dime a dozen. go to the junk yard and get a good engine harness or find the connector off of one and repair your harness.

you can tee off any vacuum source at the intake manifold. if you are unsure if you have a good vacuum source then purchase a cheapo vacuum gauge at the auto parts store and connect it to the vacuum port you want to use. your idle vacuum reading should be ~20-25inHg
