I asked Joe sort of the same question as I already had the timing advance on from my previous tuner.Here’s a new question. Years ago I had a forum member do the 2 degree timing advance.
Not sure if it was eventually wiped out but will the uprev tune have any issues if it’s atill there? If so will it wipe it? Will I notice?
I’ve read the O2 sensor won’t reach on one of the pipes and some people extend the wires.Not better fuel economy for me - probably due to the increased use of the gas pedal.
Still have front and rear factory spec O2 sensors - one in the JBA header and one on the catted B pipe. Uprev tunes the engine - so no fooling of the O2 that I know of.
No mods to the O2 cable, they all reach. Same stock sensors. Can use what you have.I’ve read the O2 sensor won’t reach on one of the pipes and some people extend the wires.
Can you advise on what is required to maintain the O2 sensors? Also, can the existing ones be reused or do they need to be replaced?
Great! Jeff also responded with the same if I use the Heavy Metal Cats.No mods to the O2 cable, they all reach. Same stock sensors. Can use what you have.
Glad I was able to find someone for you. If it comes out smelling roses, then it is all due to me. If something goes wrong, then talking to him was only a suggestion.Great! Jeff also responded with the same if I use the Heavy Metal Cats.
I reached out to the Craigslist guy that tchjts1 found and spoke to him last night. He works at a Nissan dealer around me and does side jobs in the shop after hours so I am going to go with him. Seems like a nice guy over the phone.
First ,i am very new to the armada . I have never driven one and have had one sitting on the lawn for a month or two.Jeff's catted B pipes relocate the secondary O2 sensor to AFTER (downstream) of the cat which keeps the CEL off. On the factory setup they are in front of the cats; essentially the ECU doesn't even know they are there.
Also there are 2 bungs on the headers for the primary O2 sensors, make sure he installs the primary O2 sensors in the upper one. If you try extending the wires it will cause all sorts of other problems.
