Bochim Posted May 23, 2013 Share Posted May 23, 2013 Just wanted to post what i have and see what other on here think. Any feedback is appreciated. http://i1354.photobucket.com/albums/q700/gork138/dynopost_zps8dc38c5d.jpg Car: 2005 LGT base Transmission: 5speed Target Boost: Not sure, I have seen AP boost reading at 20psi Target AFR: No clue. SAE Correction factor:? Fuel: 93 pump gas Engine/Power Modifications: BNR 16g, catless up, Cobb highflow catted down, Magnaflow cat back, Perrin turbo inlet, K&N air filter. GFB BOV. Cobb AP V2. Driveline Modifications: Stock. (At the the time of this dyno the clutch was the original stock 90 some K. It was slipping after the tune. True reading?) Suspension Modifications: None. Other Modifications: Heavier rims. (Maybe 2-3lbs per rim) Link to comment Share on other sites More sharing options...

Underdog Posted May 23, 2013 Share Posted May 23, 2013 Agreed. How did you plumb up your wastegate and boost control solenoid? The Crimson Dynamo Link to comment Share on other sites More sharing options...
Bochim Posted May 23, 2013 Author Share Posted May 23, 2013 Agreed. How did you plumb up your wastegate and boost control solenoid? It's all set up stock, I didn't really change anything with the lines. What dose t seam right about it? Link to comment Share on other sites More sharing options...
Underdog Posted May 23, 2013 Share Posted May 23, 2013 Well it's just a guess due to the lack of info. What gear was this done in? It would be good to see the boost on the plot. It would seem like your boost was coming up very slowly since you should be hitting max torque earlier in the power band.

I guess this is kind of a vague question but what normally would cause a condition like this? Link to comment Share on other sites More sharing options...
Underdog Posted May 23, 2013 Share Posted May 23, 2013 Well, did you have the car tuned or just dynoed? Your tuner will be able to explain their boost control strategy. The reason I asked about your wastegate plumbing and boost control solenoid is that 1) the BNR16G comes with a larger wastegate nipple, so some re-plumbing is necessary and there is an opportunity for a mistake; and 2) the way your torque is so low and late makes it look like you have bypassed the boost control solenoid ("BCS") completely and the wastegate is creeping open. You could also have a post-turbo boost leak. If so then you need to be very careful and get re-tuned immediately after fixing it. How does the car feel?

They told me they tune there cars to be "safe" (Not over stressing the motor) What does the re-plumbing include? just a larger hose? I just used the stock stuff when i hooked everything back up. The car drives and runs great. Was a little concerned as too why the spooling took so long becuase alot of people on here do say the 16g is qucik. Looks like ill have to give the shop a call and see if they have any ideas. Link to comment Share on other sites More sharing options...
Underdog Posted May 23, 2013 Share Posted May 23, 2013 I use a PCV elbow to a reducing tee. The PCV elbow goes on the wastegate barb and to the large side of the tee. I cut the stock line that attaches to the boost pressure signal barb (on the output of the compressor) a bit short, but make sure to leave the "pill" section intact. Then I attach that line and the line that runs under the manifold to the BCS to the small ends of the tee. It's possible that BNR has changed the wastegate barb size to resolve this. I am getting one in today for a customer build and will take a look. The Crimson Dynamo Link to comment Share on other sites More sharing options...
Bochim Posted May 29, 2013 Author Share Posted May 29, 2013 The shop has still has not called me back... Starting to think I'm just going to have to get it retuned somewhere else. Link to comment Share on other sites More sharing options...

Does the line have to be a certain diameter and length? I've been searching and I can't find anything on it. Thanks in advance! Link to comment Share on other sites More sharing options...
TheBlackPearl Posted November 8, 2013 Share Posted November 8, 2013 I used a plastic barbed reducer to go from the 7/32nds line from the compressor nipple to the 5/32nds line of my ebcs.

Bochim Posted May 1, 2014 Author Share Posted May 1, 2014 I still have not resolved this. After doing a lot of reading and fooling around with the car and accessport, I'm thinking I have a combination of a bad tune and needing re plumbed. I know everything on the plumbing is hooked up just like the stock set up was same hoses, everything. I also know that when doing a pull, my accessport will read around 20psi max. Also in weather 45ish degrees and under in WOT it will almost always over boost and I get the fuel cut off and p0244 waste gate range code. I'm defiantly not an expert on this sort of thing so I'm thinking I will just have to pay some money out and have a good shop get this right.

need bb Posted May 1, 2014 Share Posted May 1, 2014 The peak power or boost isn't any issue. It is that your turbo is spooling very late. You should be reaching peak torque around 3500 RPM's where your car looks to be around 5K. If you can't figure it out it is best to bring it to a local tuner who can review your wastegate setup and look at your tune. Link to comment Share on other sites More sharing options...
BrandonspecB Posted May 1, 2014 Share Posted May 1, 2014 Yeah, that's a 35r powerband only missing 300 horsepower. Link to comment Share on other sites More sharing options...
JermTheElf Posted May 1, 2014 Share Posted May 1, 2014 What boost controller are you using? I had this issue with the grimmspeed 3 port electric one and had to swap in a manual boost controller to fix the issue. Link to comment Share on other sites More sharing options...

I get the feeling I'm going to have to get it re tuned though. Not a whole lot of options here in NE ohio so I might be making a little road trip somewhere. What boost controller are you using? I had this issue with the grimmspeed 3 port electric one and had to swap in a manual boost controller to fix the issue. The stock one. I was thinking about changing things around and trying to "fix" the issue, but (this is my not knowing about how the ECU programing works at all with this system) wont if I modify the existing system that will throw off the current mapping? I have downloaded access tuner and tried to open the map that the shop made but it is locked. (I also e-mailed, called, showed up at the shop many times over the past year for any kind of help but have gotten nothing. I am very disappointed and feel like I waisted a lot of money on taking it there) So I can't really do anything with the current map or make my own since I have no idea where to really begin. I'll probably just end up taking it somewhere. Car is still fun to drive though even in its current state. Thanks for this insight. I will try a few things before handing the keys over and hopefully its something easy and inexpensive. Link to comment Share on other sites More sharing options...
