02 Sensor Extension Kits

[EllowViper]

I want to relocate my 02 sensors on my Belanger Headers to the **** that was welded on the main collector vice the single tube on each side. The easiest way would be to simply install "snap in" wiring extension kits. Does anyone make these? I see they offer them for Mustangs and GM cars..but I could not find any for Dodge applications.

Or Dan Cragin at DC Performance sells the whole o2 sensor with the extended lead on them. Thats what I bought when I put my Borla headers on

 

[EllowViper]

Now why couldn't I find these??? THANKS!!

I just relocated my O2 sensors on my Belanger's as well. I ended up soldering my own wire extensions. My Belanger came with one **** location in the primary tube, not sure why. I welded bungs in the collectors and moved my sensors there after my car began running ridiculously rich. This started as soon as I installed the Belangers. I suspect that since only one cylinder was being read it may have been running lean and the PCM adjusted the whole bank to run richer. After relocating the sensor, my AFR went from 10's to mid 12's and I'm fine tuning the AFR now with my Vec3. I'm pretty much stock except the exhaust.

 

[EllowViper]

With my new ROE install (yet to be tuned) its now running like Cr----p. Missing and popping on acceleration. I hope the fact that I am using the single bungs on the right/left tubes is contributing. I have several bungs that have been added so I plan on moving to the ones in the main collector (all five banks on each side feed). I can't get into M2 Orlando for tuning for several weeks, but I still want to drive. I gotta believe the basic ROE card should be tuned for driveability. I'm not throwing any codes, but I'm sure going through the gas.

 

[ViperTony]

I have the same problem with the Vec3...car run like crap at WOT. I've gotten closer to a better AFR but I sill have sporadic hesitation when stomping on the gas. Feels like a miss. Sometimes, during WOT pulls my RPM needle bounces/flutters between 4K and 5K RPM. The logging I do through the Vec3 shows a non-smooth power curve with dips along the way. I wasn't getting this prior to the Vec3 installation. I'm trying to get to a tuner next week and see if we can resolve this. I'm beginning to wonder if the new Vec3 units have issues.

 

[EllowViper]

Received the 02 sensors from Casper Electronics as recommended...and guess what...the f'ing things are the wrong ones!! I have the round four plug 02 sensor connectors and the extensions came with square. Hopefully, they have ones for a 2001 Viper; vice simply "VIPER". I really hate wasting time dealing with wrong parts.
Viper Tony, sounds like we are having the same piss-poor condition with our cars. I discussed with Sean at ROE and verified my VEC firmware update and smart card tune. He thinks a vacuum issue, bad plug wire, or some other "mechanical" condition. I have to do a bit of checking on these areas. Here are my symptoms:
-When I stand on it, I get several misses and pops out the back during transition to open loop. Like you, it seems to die out somewhat from 4000-5000 rpm. It doesn't pull like there's no tomorrow. Also, on decel during normal driving, I am getting ALOT of poping and backfiring out the back...more than the normal burbling. Sounds like crap.
I switched to the 9D card just to see if there was a difference...at first it seemed better, but them it started acting like the 6D card. I pulled two plugs and they looked fine (1 & 3). When I pulled the 02 sensor **** plug out where I want to relocate my 02 sensors, it was really black (both sides). The 02 sensors looked normal though.
Next plan is to check the diaphram on the bypass hose on the blower and check all my plug wires (Sean's recommendation) I'll also make sure all my injectors are firing since it does seem like at WOT there is something going amiss. But first I need to get my 02's back in with extension kits...!!!! I may pick up the ROE software $99 and a cheap Windows XP laptop to do some data logging. I do not have an Wide Band yet....but I expect soon.

Has anyone tried these? Our factory O2 connector is round, and the one pictured looks square.

 

[Joseph Dell]

You need to CALL casper if you want to order the round ones. a friend of mine ordered on-line and ended up w/ the sqaure ones even though he needed round. some years use the round and some the square.

[Steve 00RT/10]

The OEM sensor wire is long enough. You don't need extensions. Just need to creatively re-route the cable.

Thanks JD!

Steve - passenger is, but not the driver side. Also, depends on your application (I have a CPE TT set up).

 

[Steve 00RT/10]

I was able to do both sides no problem with Belanger headers / exhaust. The Roe doesn't interfere with anything down there. Different applications can pose problems.

Yup, no problems with Belangers. That's what I had before the TT set up.

I took Joseph Dell's advice not too long ago and made my own extensions...I followed his step-step directions which entailed going to Radio Shack and buying a roll of wire and heat shring tubing $7.00 in total. I soldered my own extensions. Took less than 20 mins. Since I relocated my O2 sensors to the Belanger collector area my engine light came on once. Hasn't come on in 2K miles. The Wizard suggested that if my light does come on, due to the O2 sensors not warming up fast enough, that I heat wrap the area around the sensor with some header wrap. He swears this works but I haven't had a need to do it yet.

I ordered mine a couple of months ago. They were insistent that they knew which plug I had when I told them the color of the connector. I wanted to send them an e-mail pic of the 02 sensor, but they were positive. They sent me the wrong one's. They overnighted the correct one's, but they are not exactly the right style. One of the connections has an additional ear which they cut off with an exacto knife.

According to Dan Craigin, if you are going to splice additional wire in for extensions, you should do so at the harness and not at the 02 sensor. I did not want to cut the factory harness to accomplish the task. Sounds trivial but I wanted the factory harness untouched.

Tator gave the OK to splice near the O2 extensions. If it's good enough for Tator then its good enough for me and the Viper. A very trivial task but it has to be a neat soldering job. Although I'm running NA (not for long) I have similiar issues as you. Coincidentally, my problems started as soon as I installed the Vec3. I did end up replacing a TPS sensor that went bad and was sending the wrong voltage at WOT. Sean also steered me to a vacuum problem since my MAP sensor output at WOT shows a loss of vacuum. This happens between the 4K and 5K RPM range. Sean dismissed it by stating this was normal and that my throttle bodies can't supply the air the engine is looking for. I've outgrown them. The logging feature of the Vec3 helped diagnose my issues and will help Sean get to the root cause. He saw the TPS issue immediately with MAP data in the logs. He showed me how to log the TPS voltage with the Vec3 logs and we found that bad sensor issue. But now, my logs look fine. AFR is smooth across the RPM range, TPS sensor output normal but I'm still showing a drop in vacuum during WOT. Still no explanation about what I call the "fluttering" of the RPM between 4K and 5K. I'm going to have my valvetrain inspected. I swear I notice that my left bank valvetrain is chattering much more loudly than the right bank as of late. I'm going to do T&D rockers soon anyway. You need to log AFR and get the Roe software. Well worth it. Without at least the AFR readings, you're troubleshooting in the dark.

Casper swapped out the extensions for the correct ones but like CamFab, I had to cut a tab off the harness plug for the "correct" OEM connectors to work. For the ******* around I had to go through and the $60.00 I would have expected better. I am throwing the right and left bank 02 sensor heater malfunction CEL. Once I get things tuned and balancing the injector offsets to where the adaptives are searching, I plan on going back to the original location. I may try the Tator solution just to see if it works.

 

[ViperTony]

Tator told me to wrap the O2 sensor as well as the pipe. I did a search and found some old posts from Steve00RT/10 that discusses drilling larger holes in the O2 sensor to get them to heat up faster and avoid the check engine light. Does DC Performance still sell the quickfire O2 sensors?

 

[Camfab]

Yes, DC sells the Quick Fire sensors. I used them on my car. No issues.

 

[Dan Cragin]

We have O2 sensors with longer leads. These "quick fire" sensors have a quicker response rate and a faster heater that gets rid of warm-up trouble codes found when using headers on 2000-2002 Vipers.

DC Performance
310-841-6996

 

[ViperTony]

Thought I would post this information here. For reference, Casper's Electronic DOES make O2 sensor extensions for the GenII's and they fit perfectly. I ordered mine from Jeg's, part #109034. The kit below is for the 24" inch extension.

 

[dave6666]

How many pesos?

 

[ViperTony]

$21.99 each. Want to save money? Either extend the wires yourself (as you did ) OR when ordering the quick fire sensors from DC Performance...tell them the length you need as I'm pretty certain they will extend them for you...which I forgot to do. Don't get me wrong, the quick fire sensor wires were just long enough but a little too snug for me. After seeing how you routed your O2 wires Dave I decided I wanted to do the same and simply ordered the extensions to help speed things up.

 

[Camfab]

Talk to Dan at DC as to why you should not extend the wires on the O2 sensor.

 

[01ACR/VIPER]

Extend as far as harness side or 02 side?

 

[ViperTony]

Talk to Dan at DC as to why you should not extend the wires on the O2 sensor.

(1.) Should not extend the wires on an O2 sensor in general?
or
(2.) Should not extend the wires on DC Performance Quick Fire Sensors?
or
(3.) Is it how and where the splice is made? i.e. harness-side vs. sensor-side?

'Cause DC Performance's O2 sensors come spliced and extended already...

 

[dave6666]

My understanding having talked to DC as well as many others is, you can splice and extend the chassis side of the O2 harnesses, but you never want to modify the sensor wires themselves. What they come with is what you should leave them at. They are not regular copper wire from what was explained.

When I did the chassis side extension it was solder followed by adhesive lined heat shrink followed by plastic loom followed by heat wrap sleeve.

The only problem I have had is when I hose down the engine bay twice a year or so I will get a preheat code on the driver side for a few days. It goes away until I do the wash down again. I assume it is water getting into the heat sleeve because of the angle of the sensor under the car. I might put a drain hole or something next time I've got the car up in the air.

This is what mine looks like now.

As Dave said.....

(1) That is correct

(2) That is correct as well

(3) Splice the factory harness

I have the quick fire sensors from DC and they are not spliced. The wire I believe was marginally longer, not long enough for my SVS application. I used the Caspers plug in extensions. No codes, no issues.
