Still working....

blakeboys

On my 2002 CC I bought a flowmaster super 44 it was 2 1/2" in 2 1/2" out and it works... sounds damn good without the cats too

blakeboys

2 1/2" going to the muffler and going out

Well said...

... http://www.dsmtuners.com/forums/articles-electrical-wiring/221951-making-your-own-rear-o2-bypass-simulator.html Well the bypass i made using the schematics a couple posts up will work to bypass the sensor part of the o2 sensor. Then following the link I in my quote above will show you a design ...

My sensor is working just fine and I am not going to want to cut the wires on it. I didn't cut my o2 sensor wire because just in case this device turned out to a total waste i still wanted to have a functional o2 sensor. I simply splice into the ecu side of the o2 wires. Therefore i could easily re...

blakeboys

yes and after reading everything displayed here http://www.o2simulator.com/doc/o2sim_installation_manual.pdf I'm convinced. This page states that if you want totally remove the o2 sensor then they use a 20ohm/20 watt resistor and give pictures too.... sounds like your problem there is solved! I'd st...

... Wiring for the HO2S (Bank1 sensor2): Pin A - TAN/WHT = Low signal Pin B - PPL/WHT = High signal Pin C - BRN = Ground Pin D - PNK = Ignition 1 Voltage (hot in run and start) Huh.... guess i should have asked you before doing this project... so i grounded my bypass's black ground wire to the tan ...

blakeboys

Nooo I didn't try disconnecting the o2 sensor completely...I just spliced into the ground, power and cut the o2 sensor signal cable going to the o2 sensor and connected my signal wire into the o2 sensor signal wire leading to the ecu. It might work either way but from what I've read the ecu can stil...

blakeboys

I 2ND THAT! Replacing the sensor would be a good idea if it's dead. Even if you use this bypass you still need the o2 sensor since our o2 sensor has a heater which the ecu can also detect as resistance i believe... But other than that another day has gone by and the short drive to work and back (~10...

blakeboys

It'd probably work however, from wat I've read the o2 sensor near the air intake does much more random and precise signals to the ecu I think if u did hook this up I'd really effect ur performance

blakeboys

I could run enough wire to allow it to be place in the rear of the cab. I first wanted to place it under the hood directly into the ecu but there were soo many wire I didn't have the patience to test them all but if u or anyone else knows which pins are the power, ground, and signal then we could bo...

I went under my truck and checked everything out. Here's the color coding for the R-G-B wires of the bypass to the trucks ecu harness of the o2 sensor: red (power) splices into the pink wire, green (signal) connects to the purple and white white leading to the ecu (leave the purple and white wire le...

blakeboys

When i made mine i designated the power-red, ground-black, signal-green....so i can do the same..... cant get any easier. Tomorrow if I wake up early enough before i work ill check out the wires i spliced that lead to the ECU and snap a couple pictures with my phone.

blakeboys

Here is the schematic that I revised. This is the same as the other one that i've previously posted however instead of R1 and R2 labels i inserted the exact component name. This makes it a hell of a lot easier I promise.

blakeboys

I drove 35 miles tonight at 55mph and rev'd it up to 4500 rpms and still....no SES light. Sunday I'll try to make another bypass up it'll be something fun to do since have the day off. Using the left over resistors i have i only need to buy a few parts but including shipping it'll all add up to be a...

blakeboys

I got few left over capacitors. I just need to buy a perfboard and 555timer but i might make another one or two if you or anyone else is interested just to cure your curiosity of course :D and ya in the process make up for cost of everything. It took me about 4-5 hrs to make the last one since i hav...

blakeboys

If you check out the picture i know it might look too simple or too good to be true but ive drove it for about 15 miles or so altogether and shutoff and turned on the vehicle about a dozen times checking my welds and still NO Service Engine Soon light!!! http://axistechsystems.net/images/oxysimpic_s...

blakeboys

Haha no problem! i did quite a bit of searching online and finally stumbled across a link and i got a schematic for it http://www.dandmcollectibles.com/images/o2sim.jpg then went to radioshack and bought the parts. Catalog part numbers from Radio Shack stores: (NOT for their online system) 276-309 X...

Sorry it took so long for a response, just got time today to put everything into action. After suspecting the catalytic converter and hearing everyone's suggestion to check the cat i decided to do away with it. I cut a a small section away on the bottom of the the cat with an angle grinder then chis...

Ok I guess ill pull it out and check but wouldn't i get a different dtc instead of P0101?

blakeboys

Well I had my brother go buy the 2 1/2" piping for me but when he came back the pipe he had was 2" so instead of driving back up town i decided to just cut a hole in the bottom of the precat and bang all the junk out and weld the piece back in :D well all went well and after driving it for a day we ...

blakeboys

Sweet :rock: Ill remove it all together then and straight pipe it. But either way I never really intended removing the main cat since i seen too many posts where HJ said " it's a high flow cat". Another question: Would the exhaust sound better with a cat back straight pipe, no muffler or better with...

blakeboys

Bring an old thread back to life because i didn't feel the need of creating a new thread :D. Well tomorrow I plan on using my new auto darkening welding mask so what better to use it on then my 2002 CC exhaust since im also installing a flowmaster super 44. SO I've been reading alot on folks removin...

blakeboys

Real wheel bearing? First I'd check a bend brake pad. Replace wouldnt hurt either. Real possibility since we have 4wheel abs. A bad/bent brake pad caused my girlfriends car to recently squeak like hell.

blakeboys

no need to remove the drive shaft?

blakeboys

Thanks for the fast response! So since the rear drive shaft goes into the transfercase i should buy an output seal?

blakeboys

Hello again, I changed my fuel filter today (got hosed with gas!!) while down there I noticed some dripping transfer case fluid. There were some small drops where the rear drive shaft go into the transfer case. My guess a seal of some kind, however does it take a input or output seal? and would this...

I replaced the transmission mount. I did have to remove crossmember :( however i did get it on there successfully but afterwards i checked the motor and unfortunately the engine mount is gone too. Question: Is it easy to replace a motor mount or does it require a lift and tools. or do you think i sh...

blakeboys

ok i think i cant handle that. Thanks for your help. Also when i have time i'll post some picture of my truck .

blakeboys

ok i checked to see if it was an engine mount and that seems fine. So i priced the transmission mount and it's about $10 at AAP. My question now is how hard is it to replace this?

blakeboys

I have a 6" Superlift installed on my truck and when I accelerate quickly or slightly peel out of dirt or wet pavement a hear and feel a loud knocking sound like clunk clunk clunk clunk today as i was underneath my truck welding a flowmaster super 40-4 exhaust in I discovered where the noise was com...
