Has anyone installed this without using a boost gauge to do the initial calibration? Mine is coming in today, and I'm anxious to install it because my old one is completely shot. I'm a little freaked about doing it without being able to monitor the boost. Has anyone had any success here? Any pointers? Or should I really install a boost gauge to boot?

Re: IPD TCV question. (wilhelmscream)

You don't need a boost gauge. <p>Just install it, reset the ECU and then go for a drive where you stay out of the boost until the car warms up, then do a series of runs where you lay into a bit more each time, but don't go flat out. Turn it off for a half hour and repeat.<p>That's what I did with mine, and it has worked perfectly.<p>Cheers,<p>J

Re: IPD TCV question. (Needsdecaf)

The directions don't say anything about the red button. I didn't touch it. I'm sitting on the side of the road after my first set of runs now. I've got about 5 minutes left until I go again.

Re: IPD TCV question. (idiomaniak)

Okay, so things aren't going that great. After doing two runs of using increasing amounts of boost each time, this thing feels really weird. I'm getting much slower throttle response than before, and the boost cuts out and stutters worse than with the stock TCV. Did I do something wrong? will this thing eventually "learn" and right itself? It seems like right when boost is going to really wind up and kick, it makes sort of a chirping sounds and cuts right out. Is that part of the process? I haven't really pushed it hard at all yet. Someone who knows what's up, please advise. Sort of freaking out about this. <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/confused.gif" BORDER="0">

Re: IPD TCV question. (wilhelmscream)

No, what you are experiencing is not normal. <p>This thread may help you with trouble-shooting the TCV: <A HREF="http://forums.swedespeed.com/zerothread?id=104225&page=1" TARGET="_blank">http://forums.swedespeed.com/z...age=1</A><p>The firs thing that I would check is that you've connected the hoses properly and that they haven't come loose.<p>IPD should really be providing instructions regarding checking the alignment of the TCV, particularly since it is possible to take it apart to clean it, if necessary (nevermind that they shouldn't be shipping any that aren't properly aligned anyway).<p>Best of luck!<p>Jeff

Re: IPD TCV question. (soupandspoons)

I'm pretty damn sure that I ran the hoses correctly, but I've been known to be kind of a spaz from time to time, so I'll double check it in the morning. I read the thread about checking the alignment too. Thanks for posting that link. What sort of damage could I potentially do by leaving it in being improperly adapted? Should I stick with it for a while to see if it gets better, or put the factory one back in?

Re: IPD TCV question. (wilhelmscream)

IMO, what you're experiencing is that the ECU did NOT adapt to the TVC. Take off the battery cables, and touch them together for 20 seconds. Then, go thru the adaption procedures all over again. You ought to be good to go assuming you connected the TCV right in the first place.

Re: IPD TCV question. (Short Circuit)

I think you're right. I did the battery thing this morning, checked all of the connections, and went for a spin to run through the break in procedure again. What a difference. Throttle response is back where it should be, and the boost seems nice and smooth through the entire RPM range. I'm waiting for the car to cool down completely before I go for round two, but I think I'm all set now. Thanks a ton. I was having a defcon 1 freakout last night.

^^^^^^ Fantastic! Glad this helped. We don't want any stinkin' DEFCON 1's around here!

Re: IPD TCV question. (wilhelmscream)

Why did you replace the TCV? I am going to start chasing a stutter problem here myself. I got the MAF cleaner and bits to start, then I was going to do the TCV. Then I guess FPS. I have peen trying to put a game plan together.

Re: IPD TCV question. (dave_n_ruth)

Mine was stuttering really bad. I took it in for the 90K service, asked them to check it out, and they said it needed to be replaced. They quoted me $300 to do it, so I figured screw that, I'll do it myself for $80, and do it with a better part to boot.

Thanks, I have been avoiding the Stealership for a while now. Even with a problem I am better off throwing parts and money at it than dealing with the $h!T I get from them.

Re: IPD TCV question. (dave_n_ruth)

I'd like to do more work on it myself, but I really have no clue what I'm doing when it comes to working on cars.

Re: IPD TCV question. (wilhelmscream)

I will do anything on my Jeep, but I have always been afraid of the R. I guess its time for me to learn. I got the time and internet is a great resource. The XC90 is my daily driver, so I got time to make mistakes.<br>

Kudos for re-setting the adaptives <IMG NAME="icon" SRC="http://********************/smile/emthup.gif" BORDER="0"> <p>IIRC, the red button on the bottom is not a button, its a plastic/rubber cover.

The TCV is so easy that there is no need to remove anything, including the dead space cover in the corner (unless your hoses are really, really short). You can slide it off the air box, pull it up above the dead cover to work on it, swap it out, and put everything back. Only tool needed is a pair of pliers for the hose clamps. Only takes a minute.
