The dealer said my wire was soldered and shrink wrapped but i looked and looks more like electrical tape. I did not look under the tape to see but i will prob put some of that ribbed harness covering on it next ime on the lift and think about re directing the wireing all together. I spent a couple of hrs molesting my car with a good waxn with this stuff called The Black Box. What a pain in the ass and i have black hands too. OH YEA, THE DEALER TRIED TO CHARGE ME $22 FOR THE GAS THEY HAD TO PUT IN THAT THEY USED DRIVING IT AROUND.



There is a clear bra on here, The line is about where the trunk of the palms are,

 

Well I wish it had thrown a code so they would maybe had done something othere than switch things sround and try to charge me for the gas they used. It looks like it is shrink wrapped with some stuff looking like elect. tape. I can see the rubbing and bumping causing the car to freak into limp mode( but also the flutter?) Or are these 2 diff. problems?

 

It's tough to say. When mine was crapping out I would get some flutter (heard it while in the garage) since the air is bypassing but I wasn't paying a lot of attention. I was more concerned with the car running like hell. Mine was put in similar to yours (soldered, taped, heatshrink, etc) but water had gotten in over the winters and corroded the harness to hell resulting in poor communication with the sensor. All in all it's a pain in the ass to cyber out.

I can't remember but has the dealer run checks for boost leaks? Mine also did this depending on weather conditions when the lower radiator bolt started wearing a hole in the harge piping. When cooler it was fine, warmed up leaked and no more than 5psi (though normally) but don't think I had flutter in that case.

 

The dealer did not do a boost leak test. I really do not think they fixed it by swapping the map sensor with the boost sensor but knock on wood it has not done it since.
I did beat 2 tangs this weekend though.They were surprised I beat them. Just noticed that i need to put car on my lift to rotate tires this weekend. I am wearing them out too fast!!!

 

I have flutter and I have a BOV.

 

Many people told me I had to get a BOV to STOP the flutter( so much for that being a solution), but if it did not do it the first 8mo. then It is not a mandatory item. I do not want one just for the reason of the sound but later will poss. put one of those Forge BPV on.Not too sure what they sound like though?

 

So I have the saaaaaaaame problem and its pissing me off. I have turbo flutter whenever i shift or let off the gas and my boost doesnt go past 5 psi. I have taken it to the dealer five times and they keep telling me they cant find anything wrong with it. So did you get yours fixed. I also have the gms1 and a K&N SRI. This will happen one day and then the next day it will drive perfectly fine and get 21 psi boost. What did you do to fix the problem?

 

Hey buddy,
I dont realy think the "fixed" anything since nothing got replaced. What they did is swap the positions where the MAP sesor was with the BOOST sensor. The car has not done it since(knock on wood).What puzzles me is that why would swapping those positions "fix" the problem? The car did not come configured that way so why is it f***ing up now unless a part went bad? People tell you that you have to get a BOV or a BPV to solve the problem but thats crap too. The car was fine without it for 9mo. so It is not mandatory, something else is wrong. I may be puttung on a Forge BPV though. Looks more sturdy than stock. If your dealer is still stumped PM me and I will give you my dealers # to give to yours. Let me know how it goes.

 

Well I guess I should have really knocked on wood cause on the way home from work this evening sure enough flutter and limp mode!!!!!. I am pissed too. Called the dealer and will be dropping the car off in the morn. I knew just switching the positions of the 2 sensors would be too easy of a fix.( not even really a fix since nothing was replaced) I find it hard to believe that we are the only 2 who have this problem and they cant find other dealers who have already had to deal with this and know how to fix it. I want to know what STOCK part went bad and is causing this problem. not what aftermarket part I can get to solve the problem.

 

So I took it to the dealer today and it was fluttering and only puttin out 5 pounds of boost. Finally after the fifth time bringing it to them, they found that the bottom of my charge piping had a huge hole in it. So I really hope this fixes the problem.

 

Man I hope so too. Could I have a hole as being my car is so new with only 13k on it. seems not long enough for a hole to wear but who knows. Reading you thread I think mine is a little different. I am thinking the BPV or something. I hate that its randome so the dealer does something , it stops doing it so they give the car back and say its fixed then a week later it comes back. Sombody at GM has to know what the problem is!!

 

ya you would think they would. I pretty much told the dealer what they need to look at just from reading some forums. I found that its either the charge piping, the BPV or the sensors at the bottom of the charge piping. Sure enough it was one of them, so I would tell your dealer that too

 

Were you at WOT when it did this? Reason I ask is that the lower TMAP is notorious for hitting the AC compressor as the motor rocks back under torque load and can cause the drop in boost. You'd be surprised at how much the stock mounts flex, even brand new. It might not be THE sole purpose of your flutter, but it may be a contributing factor.

I can mention it to the dealer but It does not happen while WOT. semi normal driving. I sure hope they find it. I think their tech support is going in the direction of the sensors. I personally think it is in the direction of the BPV, but what do I know. I think if they would contact the engeneers who created this "tune" they may get some answers since it seems to be a GM1 problem. well I guess another week without my car. yipeeee

 

Yea they just called me to tell me the car was done. They said the replaced both sensors so i should be good to go. They said they could not feel the clutch pedal creek. I think they are just tired of working on my car.

Lets hope this fixes the problem.

 

Well I guess this did not fix the problem. I was on my way to wally world and had flutter and limp mode. car is at dealer again. they did say the re-flashed it before and did replace the sensors and I in the mean time put on the forge BPV so now we will see what they have to say. The head technition is comming today. I said if gm would still honor my warranty I woulg get the trifecta tune and be done with the problem. Will keewp you posted.

 

if your only getting 5 psi it's the gm stage 1 kit. you have to solder the wires going to the map sensor...

 

they claimed they have soldered them.

 

I once in a while get the same problem.

I don't recall it ever happening before I got my GMS1 though.

Then a year ago I got an HP tune, still happened to me.

I got a forge BPV, and not an intake, it it has happened to me once just recently. Not a big issue, but as it's intermittent it's hard to get the dealer to check it up.

Usually it's like this, and the next time I use the car all is good, and then it comes back once weeks later. The other day it did this, and as I was driving it suddently got fine.

As you guys, I hget no more then 5 psi and car feels vbery sluggish when this happens!

 

Even though you got the HP tune you still have GM1 in the car so I assume? I still think it the GM1. It is just a pain in the ass!

 

Dealer called today and wanted to know where I got the kit. I got it from Crate engine depot. The dealer said there have been cases where there have been bootleg kits out there and they want to see if mine is one. Could this be the cause of this whole mess? I will keep you posted.

 

Nope, what they are saying is that sometimes you will see people piece together the kit themselves.

CED is a GM certified dealership. It's the real kit, hence why the tune they loaded actually works.

Oh and I had the same issue. They are covering their ass and I think the regional rep is covering their ass on that statement.

 

thats what I thought. What fixed your problem?They are talking about insalling another kit. I think if there are that many of us with the GM1 problem that they need to go to the people who designed the program and get answers from them. I tried to track them down on my own but to no avail.

 

Dealer called I wioll be w/o my car till Mon. Now they are ordering a new harness. Said it could be faulty. I think they have no clue myself. I wish my Z28 got better milage...

 

Got car back today. Guess they replaced 2 harneses. we will see if this does the trick. Still trying to get them to fix the "creak" in the clutch pedal. My car must have been built on a Monday by a crew with nasty hangovers.
