I received my PC V today.. I got right on the install, question is do you remove both front and rear 02 sensors or just the front? I for some reason can't seem to figure that part out.. I think its just the front unless your using AT?

Also, if it seems to run good, is their a need to actually hookup the laptop to the PC V for any particular reason?

thanks for your help

 

I think i just answered the first of my questions. I should unplug the rear also, right?

 

i will be interested to hear how it performs for you, I've been thinking of buying a PCV.

 

yes unplug both and use the supplied eliminators

 

Ok now its running really good. Seems i left the rear in,, my bad..

Not sure what to do with the dangling rear 02 sensor wire that comes off the exhaust. Guess I need some black ties to tie it down. Looks like it might flop around a bit in windy conditions.

 

or remove the sensor all together and install a plug...

 

Initial thoughts on the PC V:

Throttle response seems so much better. Idles well (now that the rear 02 sensor is removed)

Gonna take her out for a longer run shortly and on the highway.

Yeah i think i could remove the sensor all together and plug it. Prob. a good idea.

Thanks for all your help.

 

Make sure you use some anti seize on the plug or it'll be a permanent plug soon!

 

Before I added the autotune I just used a zip tie to hold the wire from the front )2 sensor and just push the wire on the back one down out of the way.

 

You can keep the O2 sensors installed in the pipe, just not connected electrically. If you want to replace them, be patient removing them as they can be obstinent coming out and damage the threads. First warm the bike up and spray some penetrant (WD40, etc.) on the base of the sensor. Let it sit for a few minutes and start to remove the sensor using an appropriate socket like this one. If it gets hard to turn repeat the penetrant step, turn it in a few turns and wait another few minutes. Repeat this ritual until it's out. My front required serveral cycles but the rear came out very easily.

You can find plugs that fit at a local Toyota parts counter (#90341-18016, oil drain plug) for a few bucks. Put some anti-sieze on the threads before installing them.
