Valet mode working?
I'm confused. What do you mean by 'working'? Does the care run cleanly, and start easily? (No boost, just smooth.) If this is so, then yes, your existing tune is corrupted. Quote:
And I am not 100% convinced that's the problem, but if the valet diagnostic revealed this, it's a smart start. Less words, same answer. LOL! Someone with a sense of humor. Coop

Hey Coop thanx, The Valet mose I have set is the car will hit fuel cut at 30 MPH, The will run fine till I get to 30 MPH and the cut kicks in, So the Valet mode works. More info on driving I would notice I could be at 5k RPM and would hit no boost, Gauge would read -20? The first think that got my attention was I was merging on to the street in front of my house I stepped on it , It would ramp up and then the car would jerk( Almost like fuel cut) and boost would fall off to below 0?, I can not build any boost, Even if I step 1 tenth of the throttle and vert slowly ramp up the RPM's in first, Will get a small jerk at 1200-1400 and the at 2800-3200 the car will just burble and pop, and jerk, Know what I should take a small vid, It will do it in park,, Going to take on know.

I have had my battery disconnected many times and never lose the tune. Easiest way to check for UPREV is if you can select and change maps, and the cruise indicator blinks the proper number of times for the map selected, then the tune is still there.

Battery died not sure if its different and was down for about 8 hrs? Also when I got in the car in the am the RED security light was blinking, Called the dealer told me the battey was dead and had to jump it? Did that and now all these issue, I know there things that just happen at the same time but right before I park the car it was running perfect?

OK so uploading the vids, The more I drove it it seems like fuel cut, There is alot of breaking up at 1800-clears at 2300 or so and will start again at 3k? But if I get on throttle even a little it will ramp up an fall on its face, Lurch forward( Like fuel cut) also was a very LONG crank time to start up. 5-6 seconds, An was stumbling a lot till it go warm..
I also got a vid of the car at 4k and boost was neg 22

Hey man! You need to stop messing with it and bring it to the pros. Let's say if your blower is out your car can have symptoms like you're describing. The ecu does not know your blower is out and will keep dumping fuel and without the air from it of course it's going to take a crap! That happened to me when I first got my kit, the blower was bad and can only build 3-5psi of boost, but one thing my car did was it threw me into limp mode.
Really suggest you to take it back to your tuner and hope its not the blower. That's expensive! |

If you have a check engine light then I will bet it's your intake timing control soleniod valve. It controls the timing and oil flow. It should also be in bank 2...the driver side. My guess is it is stuck wide open. I know this because my was just doing the same thing.
Also does it start the blurpping around 2.5k to 3k? If it is doing this then you will need to change your oil and filter also remove the soleniod( really easy to do) and you'll notice it's stuck open. Simply push on the end and you will hear a pop. Problem fixed. Clean it and install. The car will run just like it did before all the issues. Also don't forget to pull the negative side of the battery to reset the ECU.

OK I am not messing anymore LOL, Just wanted to get some vids for you guys, I have been driving the wifes car, The thing about the SC is something my tuner said also after looking at the vids I sent him. I also looked around some more this morning and found SC fluid all over the back of the SC and engine bay, Drivers side, The fluid was a milky colored, So car is off the the dealer tomorrow AM, Costly better not be, Been on the car for 5 months, Warrenty..
TOWER, It starts blurping at 1800 at clears up and starts again at 2800 or so, The throttle pulls it self back also,

If you have fluid all over the place then it's the blower for sure. You might have a blown seal in the blower. If the blower is still under warranty ,then its just a matter of sending it back for a re-build. I had this happen to me on a brand new blower from Vortech on my 350z took them about a month to get it back to me. Once I knew my blower was bad I took the cog belt off the back and drove aroun N/A till I took it off.The car will drive normal that way.
