Sorry, my question meant, after the reset, did it feel ok until the light came on again?


As for the test, you needn't go back to the shop, there is no problem with them being in the pipes, just pull the plugs to both rear sensors. Perform a reset and let us know how it feels.

 

The ses light came on again with the same p200 code, oddly the car now runs better with the ses light back on. Another weird thing is the bank 1 code i still disabled but the light still came on. i dont think i would be able to remove the sensors myself im afraid i would break something .
have
So are you saying i should the shop remove the bank 1 and bank 2 sensors?

 

I was playing around with osiris today, and i saw that my rev limit was set to 7500 rpm, i thought my tuner had set it at 7200 rpm. I went ahead and lowered the rev limitir to 7200 rpms . Would it better to lower the rev limit back to the stock 6800 rpm's? , i have an automatic.

 

If your engine isn't built, I would logically say it probably isn't safe to go that high.

Plus, your power curve drops before your redline. Unless you were specifically tuned to keep increasing power all the way up, there is no benefit in being able to shift later

 

Re the rear sensors, just unplug the wires on them, simple click plugs, if you brake something doing that you've got other issues

The ses light will come on for *any* fault in the system.

 

You will run out of breath after 6800rpm anyway. Not sure what the guy was thinking knocking you up to 7500?

 

[QUOTE=ITNKICN;9775485]You will run out of breath after 6800rpm anyway. Not sure what the guy was thinking knocking you up to 7500?[/QUOTe. Lol, stock automatic hr rev to 6600 rpms so ill go ahead and set it from 7200 rpm to 6800 rpms, so i still get a slight rpm increase with less strain on the engine. I had assumed that since m/t hr 350 can rev to 7500 rpm, ,that my auto would have gotten better performance with the rev limit raised to 7200 rpm.

 

good point thanks fore the info

 

lol, is this going to require the car being lifted?if so i don't have the tools. im gonna look fore a diagram or picture of where these sensors are located

 

Haha, yes, it does require lifting, you've got a jack in the trunk

They're very easy to get at and see, they're on the underside of the gearbox where the Y-pipe is, they stick out like sore thumbs, you won't miss them.

 

i forgot i had a jack, ive yet to use it lol. im gonna look at those sensors in the morning. my car has been running better now fore the past 2 days , the ses light came back on even with the bank 1 sensor code disabled.

 

aren't the 07-08 hr auto/manuel the same 7500 rpm?

 

Oh yea your right lol... set it back to 7500

 

i think most auto hr owners set to 7800-8000rpm, not because they are going to rev it up that high but when in manual mode there's that delay to compensate for..

 

No the automatics only rev to 68000 rpm, ive since set it back down to 6800 rpm i had lowered it from 7500 to 7200. But im playing it safe and keeping it at 6800. Ive felt no difference betweeen 7500 and 6800 rpm.

 

I can also report that the boggy feeling my car had has so far not been present ( knock on wood) . I still need to get the bank 1 sensor switched out under warranty.

 

This isn't right. HR automatics have a 7500 redline, just like the 6MT ones.

Are you sure you have an 07? The 06 autos were the ones that had the same DE motor as the years before, while the 06 manuals had the rev-up with the higher redline.

 

Car and driver disagrees:

"The only exterior change to the 2007 350Z may be subtle—a new hood with a slight center bulge—but there are big changes under that hood. Power is increased to 306 horsepower, a modest six-hp bump for manual-transmission Zs and 19 for automatics, but Nissan claims that 80 percent of the Z's prolific 3.5-liter VQ engine has been changed. This is the same update—and the same engine—that powers the Infiniti G35 sedan. The changes were extensive enough that Nissan renamed its celebrated V-6 "VQ35HR" (just rolls off the tongue, eh?). HR stands for "high-revving," reflecting the higher redline for the manual-transmission model, which increases from 7000 rpm to 7500. (The less-fortunate driver of an automatic 350Z can only rev to 6600 rpm, as with the previous engine.)"

 

Thanks i was gonna reference that article but you beat me to it lol, i also realized that i may have reset the rev limit to 6800 and not 6600 rpm. Does any body have nissan literature that shows what an hr a/t revs to? I was trying to find a brochure online but no success yet.

 

I know it's wiki but it's a solid start. They're saying 6800 as well.

I went to "specifications" in the mobile version. I suppose it's not really what you asked for but if you're in that range I would be comfortable with it.
