Jehu Jehu Newbie Registered: 02/15/05 Posts: 54 Loc: NS, Canada	Hey, I can't seem to find anywhere that tells me what colour the signal wire is on the O2 Sensor of my 2000 SiR (Si in the states). I have hooked it to the White and then to the Green with no go. Also I am getting the CEL codes P0131 (O2 sensor circuit low voltage) and P0171 (System too lean) What would you guys suggest? I have only had this installed for 3 days, it seems to bog of idle pretty bad and there is a loud whistle type sound from the air intake (sounds like bad brakes) when the boost gauge approaches 0 and heads into boost My setup: 2000 Civic SiR (Si in states) JRSC @ 6 Psi Short ram intake 1 step colder NGK plugs timming set to 8 DBTC (only 91 octane gas here) boost gauge and A/F that doesn't work MAP CONTROLLER ON ORDER everything else stock _________________________ 2000 SiR w/CAI intake and short shifter JRSC @ 6psi MSD Boost Retard Master AEM Wideband Engine mount inserts 1step colder plugs

That will help you find the O2 signal. As for the boost guage. you will need to "T" a vacuum hose from one of the boost lines on the S/C and run it through the firewall and hook it up to your guage. hope this helps d

Jehu Jehu Newbie Registered: 02/15/05 Posts: 54 Loc: NS, Canada	The boost gauge is just a regular one, not the wideband sensor. I got the Boost gauge working and was told today that the white wire is the signal wire for the O2 and that I should be tapping into the wire up by the ECU.... and that that wire up by the ecu is white too. I still have the CEL for lean mixture.... I seem to detonate every so often. Do you guys think I need a high flow fuel pump? My car has 131,000km on it. ... I am getting discouraged and worried that I might blow my engine. thanks again _________________________ 2000 SiR w/CAI intake and short shifter JRSC @ 6psi MSD Boost Retard Master AEM Wideband Engine mount inserts 1step colder plugs

Dee Dee Still Not Turbo Registered: 11/09/03 Posts: 210 Loc: Okinawa, Japan	Do NOT use the narrowband idiot light type AF meters to tune your car. Even if the stock O2 sensor gives you a reading other than 13.0~14.7, the the readings will be slow and EXTREMELY inaccurate. Use a boost gauge and EGT to tune your car until you can get wide band or semi-wideband (Greddy). Check the connections to your O2 sensor. A loose connection could be causing the CEL. If someone else has tried to tap into the O2 sensor wire a broken lead might also be causing the CEL. If your connections are good you start to systematically swapout the O2 sensors and then the ECU.

What engine management are you using? It is just the stock JRSC 6psi kit with the JR FMU. How do I tune that..... I guess I must have missread about this kit working fine at 6psi with the basics. It hasn't been tuned... I live in Atlantic Canada and have no access to a dyno. I am beginning to think this was a bad Idea to install. I just found a dyno that I did not know existed here!! what exactly are they going to be able to do with the dyno? Sorry for being such a newbie..

Jehu Jehu Newbie Registered: 02/15/05 Posts: 54 Loc: NS, Canada	Also the place I had the CEL light checked at said the O2 sensor is working fine. He actually showed me the graph type thing on the code checker that shows that the voltage was going up and down between 0 volts and 1volt. Kinda just jumping back and forth. After the CEL is reset it comes back on after just idling for about 1min. Does this mean that I am lean even out of boost? _________________________ 2000 SiR w/CAI intake and short shifter JRSC @ 6psi MSD Boost Retard Master AEM Wideband Engine mount inserts 1step colder plugs

Jehu Jehu Newbie Registered: 02/15/05 Posts: 54 Loc: NS, Canada	I ordered a wideband O2 sensor/gauge. I am not boosting. My map sensor controller is not here yet. I have called Keith at Tech support but keep getting the answering machine.. left a message. I have been told by a couple of people that getting the CEL light is likely a bad wire job on our part. I am going to have the shop that I am getting the Map controller and wideband from do the install on both of these. They will have to undo my hookup of the JR enrichment relay to install the Map Sensor Controller. Once the wideband is hooked up I will be able to tell if the sensor is working right? (that is if i am getting good A/F mix and it is still throwing CEL for lean mix) When I hook up my idiot A/F gauge it doesn't show anything at all! When it is not hooked to the signal wire the light stays up in the middle of the gauge and when I hook it up it looks as if the light just drops all the way to the lean side and goes off. Could this mean that I have a faulty O2 sensor and is why I am getting the CEL? _________________________ 2000 SiR w/CAI intake and short shifter JRSC @ 6psi MSD Boost Retard Master AEM Wideband Engine mount inserts 1step colder plugs

spidermancivic spidermancivic Major Member Registered: 06/14/03 Posts: 1459 Loc: Somewhere in South Cali	a bad wire job of the o2 sensor or your o2 sensor being dead will throw the primary o2 sensor code. if your primary o2 sensor is dead, your narrowband AF gauge o2 sensor will stay most of the time in the red. the narrowband o2 sensor may be a POS, but, it does a good job telling you when your o2 sensor is dead. im assuming you are boosting the jrsc@6psi on a b16 with no kind of bandaids? if im correct, there is no lean code. there is a code for too lean/too rich......................not specifically a rich or lean code on its own. off the top of my head, i believe this is a code 42? how do your plugs look like? if you dont have any timing control, you need to set the timing to 10 degrees BTDC. also, when was the last time you had a valve adjustment? concerning the jr map controller. seems like you are on the path to picking up the JR bandaids? i would recommend you not take that route, and pick up an engine management system instead. at least a VAFC on some dsm injectors will be much better than the JR bandaids. combine these with a water injection kit off ebay and your detonation control will be awesome. as far as plugs go, i used ngk BKR7F-11s on my old jrsc setup. gapped at .038. keep dropping the gap till you hear minimal detonation. you want to try to keep the agp as wide as possible though. _________________________ wanna trade a 99 ebp si for a Pilot or CRV?

Jehu Jehu Newbie Registered: 02/15/05 Posts: 54 Loc: NS, Canada	Thanks for the reply. Yes I am boosting on a B16A2. The codes I am getting are P0131 (O2 sensor circuit low voltage bank 1 sensor 1) and P0171 (System too lean bank 1) or at least this is what the print out says from the shop that checked them for me. I haven't looked at my plugs yet. My timing is set to around 8 degrees BTDC (91 octane). Not sure of the last valve adjustment because I am not the only owner. I bought the car at 92,000km. I didn't know that I want to keep the gap as wide as possible. If I open the gap up from .035 what will I notice if the gap is too wide? I am using BCPR7ES gapped at .035. I haven't boosted since I got the code checked, but from what I remember it seemed like I was getting Tip-in detonation and that is why I ordered the JR map controller. If my O2 sensor is dead and is throwing these codes will it put my car in to some kind of limp mode? or safe mode? _________________________ 2000 SiR w/CAI intake and short shifter JRSC @ 6psi MSD Boost Retard Master AEM Wideband Engine mount inserts 1step colder plugs

spidermancivic spidermancivic Major Member Registered: 06/14/03 Posts: 1459 Loc: Somewhere in South Cali	when i ran the jr bandaids, i recieved a cel for too rich/lean. went away with a valve adjustment. i gapped my ngk BKR7F-11s at .038 with the bandaids. switching over to the hondata i gapped em at .032. your o2 sensor cel will put you in open loop mode. it is safe to drive, but, your gas mileage will definately suffer. with the jr bandaids (mapcontroller, boost timing controller, and vpac), i still had tip in detonation. switching over to hondata was like night and day. _________________________ wanna trade a 99 ebp si for a Pilot or CRV?

Jehu Jehu Newbie Registered: 02/15/05 Posts: 54 Loc: NS, Canada	When I found out that I had a lean mixture code I thought that the car couldn't be driven in boost... so I haven't. I am having Honda check the O2 sensor for me tomorrow. _________________________ 2000 SiR w/CAI intake and short shifter JRSC @ 6psi MSD Boost Retard Master AEM Wideband Engine mount inserts 1step colder plugs

Jehu Jehu Newbie Registered: 02/15/05 Posts: 54 Loc: NS, Canada	Honda checked my O2 sensor and says it is working fine. They told me that the car is just running lean. They told me to get a high flow fuel pump and bigger injectors. I then finally go a hold of Keith from Jackson Racing and he said that get a new high flow fuel pump only. He also told me to only get the 190L fuel pump and to NOT get the 255L fuel pump because that was way to much for that car. Can or should I get the 255L? (seems to be the most redily available) Is Jackson Racing just trying to get me to buy the 190L JR pump? I shouldn't get bigger injectors until I have something to drive them right? _________________________ 2000 SiR w/CAI intake and short shifter JRSC @ 6psi MSD Boost Retard Master AEM Wideband Engine mount inserts 1step colder plugs
