FURIA T5-R Posted March 24, 2021 Report Share Posted March 24, 2021 Hi, I've been having a problem with my 2.4t v70 for a while, when I get close to 5,500 rpm in 4 full gear the turbo pressure becomes erratic, starting to drop from 1.2 bars to 0.8 and then go up and then go down etc. .. it always does it around the same rpm, if I change to 5 gear it returns to its normal pressure, in fifth gear I have not been able to test it because at 5,500 rpm or 5,800 it would be something like 260 km / h, it has ever done it in third gear, but above all it is in 4, and always in the same rev range, I have a 16t and RICA update, I have tried changing the tcv, I bought the original and a porsche one, I also exchanged the relief valve from the 13t to the 16t, none of that worked, I hope you can help me Link to comment Share on other sites More sharing options...
bmdubya1198 Posted March 24, 2021 Report Share Posted March 24, 2021 If the new TCV didn't help, make sure you check very carefully for any vacuum leaks. Even a small vacuum leak can cause odd boost behavior. Link to comment Share on other sites More sharing options...
FURIA T5-R Posted March 24, 2021 Author Report Share Posted March 24, 2021 Hello, thank you very much for answering so quickly, the hoses that connect to the tcv are new made of silicone, I am not sure if any hose from the pcv system could cause that problem, what surprises me is that it is always at the same revolutions, let me explain, If it were a vacuum leak, I would also have pressure problems at other rpm, if I load the accelerator to the maximum from 2,500 to 5,500 I can get 1.2 / 1.3 bar, but from 5,500 rpm the dance begins, could it be a lack of gasoline? or maybe a bad tuning setting? Keep in mind that RICA sends the file to load it in the car without a test drive, although I think that the 16t configuration in an lpt is quite well known to them, a greeting Link to comment Share on other sites More sharing options...
Midnight Caller Posted March 25, 2021 Report Share Posted March 25, 2021 Hello ! I had myself issues with 16T in a LPT. The higher level of boost could lead to knocking and the systen cuts out in order to protect the engine. That might be your issue... Link to comment Share on other sites More sharing options...
bmdubya1198 Posted March 26, 2021 Report Share Posted March 26, 2021 Are you able to load the stock tune? If it didn’t do it with the stock tune, there may be an issue with the RICA tune. Link to comment Share on other sites More sharing options...

El nivel más alto de impulso podría provocar golpes y el sistema se apaga para proteger el motor. Ese podría ser tu problema ... Hello, do you have reassigned ecu or stock? 8 hours ago, bmdubya1198 said: ¿Puedes cargar la melodía de stock? Si no lo hizo con la melodía de valores, puede haber un problema con la melodía de RICA. Hello, in stock an lpt rises to a maximum of 0.6bar, I have not tried it, but I do not think that at 0.6 bar I have problems, anyway I will do all the possible tests Link to comment Share on other sites More sharing options...
bmdubya1198 Posted March 27, 2021 Report Share Posted March 27, 2021 I'm thinking it is pulling ignition timing for some reason. It could be detecting excessive knock. How are you engine mounts? I've heard of those causing excessive vibrations, and in turn causing a similar problem to what you are experiencing. Link to comment Share on other sites More sharing options...

Podría estar detectando un golpe excesivo. ¿Cómo están los soportes del motor? He oído hablar de los que causan vibraciones excesivas y, a su vez, causan un problema similar al que está experimentando. The engine mounts are all new, the only thing I've noticed is that if I don't release the clutch pedal carefully, it hits, especially in low gears, but I don't know if it could have something to do with it, that could be another thread. Another thing that I have noticed is that if I fully accelerate and step on the clutch pedal the rpm goes up a little just before releasing it again, the more load on the accelerator the more it goes up, I will try to upload a video, the clonk thing when releasing the pedal clutch is surely the box m56? Or could it be a poor quality motor mount? Link to comment Share on other sites More sharing options...
