I just replaced my stock TCV with a HD TCV made by IPD. Everyone on IPDs forum talks about how easy the installation was and how well it worked. I admit it was very easy to install but I have yet to get the car running properly. After I had installed it, I went through the suggested "breaking in" procedures that IPD provided in the installation instructions. After this I took it out and it ran great. came back to drop my friend off that had been helping me with the install. Dropped him off and headed him and suddenly the car was having issues with what I assume to be boost around 4,000 rpm. The car has virtually no power at this point and then starts to shudder. I know that the ECU is adaptive and I even did a hard reset so that it would be easier for the car to learn the new system. I then went back out and Went through ipds procedures the car was still doing this. Now this was all in the span of a few hours but i assumed that the ECU would adapt after these breaking in procedures were performed. How long does the system take too adapt? have I just not waited long enough or is something else going on that I need to take care of? Up until now the car had been running great. I also installed IPDs short ram air intake today as well could this be causing problems some how? Someone please help this was supposed to be a performance upgrade and it seems to have screwed some things up!!

Re: Upgraded HD turbo control valve not working properly (SaintC70)

Reconnect the stock unit and rerun the vehicle. If problem still persists then it is unlikely that either are the problem. Even with a completely non working IPD TCV the car would run fine except no boost other than at the waste gate. Your engine shudder scenario suggests that you have a problem elsewhere. <p>1. Inspect all your vacuum hoses and intercooler hoses, should be New hoses in the first place<br>2. Have the codes read even though no CEL's on in the vehicle. <p>My first thoughts are you have a bad ignition coil(s).<p>BTW: IPD has a forum that this question can also be asked.

Re: Upgraded HD turbo control valve not working properly (MKC70)

I actually replaced the ignition coil not to long ago. Had it been that the car would not have run right at any rpms. It would shudder the whole way through. Im pretty sure that the computer just needed time to adjust. I took the car out today and drove it about 100 miles and it works great now. Thanks for your help though I appreciate it. It works great once the computer learns how to operate with it and I would suggest anyone with a turbo volvo, especially the C70 T5, to get one.

I just ordered a new TCV and silicone lines based on your recommendation and all the other raves on IPD's website. Hopefully my HPT with 118k miles will see some benefit. Thanks.

So your 2001 only has one coil on the engine? Glad your issue resolved itself. <IMG NAME="icon" SRC="http://********************/smile/emthup.gif" BORDER="0">

Re: Upgraded HD turbo control valve not working properly (Chilled Man)

No it has 5, one for each cylinder and they are actually coil packs I upgraded when one of them went out about a year ago.

Re: (Luke797)

Definitely money well spent you wont be disappointed. My only suggestion would be after you have installed everything take the battery cables off the battery and touch them together, hold them for 12 seconds and reconnect them. This will do a hard reset on your ECU and allow for it to learn how to interact with the new hardware a whole lot faster.
