Finally had a few minutes to work on the car last night. I had enough time to take the y-pipe off and confirm the TB plate was working like it should. It was working perfectly and opening 100%. So if it is the TB the computer is telling it to close for some reason but I don't think that it is.

 

I sent him a recall file for Durametric it will log everything including the actual throttle position.

 

Awesome, I hope,that the data Marski is after finds the problem. I'm dying to know what the issue is!

 

Have you checked the pop valves or penny valves in the turbo to make sure the seats arent cracked as they will never seal if they are.

 

OK well here is the log file for a 3rd gear pull.


For some reason when you save it, it saves as a .php file so you will have to change it to .xls in order for it to go back to an excel file and you can open it..

Thanks!

 

Throttle is staying open, so that's good. The only thing that looks off to me is your injection time. It's dropping off at high rpms when it should be increasing. I'm no expert, so maybe someone else can give some more input.

 

Here is nothing wrong with the car. Your wgs are set to crack to low. Make sure they start at 15 psi and your issues will go away

 

Just as a helpful hint. Markski is NOT saying fully open at 15psi. He is saying at 15 psi is when they barely should start moving.

 

Markski, I will try it but like i mentioned before, the car wouldn't boost anymore even with the wastegates actuators bypassed and even wired shut so I'm not sure how adjusting the actuators will help.

Thanks so much for your help!!!

 

I will suggest logging pulls with every change you make. You might notice something different and the extra data could be helpful.

 

I understand but why don't you try what we know works and then do a log. I've never wires then shut thus can't tell you what it should be like. But I do know wgs are set to low the car will act like it should. I'm not sure why the wgs were at 11 or 12 psi to begin with. They should be at 15 psi. That's when u should see the arm to crack to move.
You will see that all this time, if every everuting else is ok like book leaks that you will solve your issue. I know logs and I know how to fix it. This is what I do

 

Sound good. I will set them to crack at 15psi and report back. Thanks again!!!

 

Any update?

 

Unfortunatly no. This weekend I had to throw the built LS6 back into the RX7 so I wasnt able to touch the Porsche. I will try to adjust the actuators sometime this week and report back.

 

do you checked the check valve on top at the TB Intake Plenum?
