The Boost Controller with a lot of names like N75 Valve or pressure converter controls your boost from your turbo. It makes sure that your car is not over boosting or under boosting in some cases. I will be showing you how to Data Log your Boost controller.

suuuuppper handy vid, thanks man, been watching all your vcds vids. When i had my mk4 supra i put a catless dump and the stock boost control couldnt deal with it/keep up so would hit fuel cut, i ended up putting an aftermarket eboost controller and was stable and under control again. same happened on my 1jz soarer, big dump just = naturally more boost

Thanks so much 🥳 and hey if you had a Supra I am supposed to watch your videos 🤣 lol. But I can Imagine it was heavily 😎 thanks for the support 🙌 more videos will come soon 🥳

@JH-sc7cs Год назад

good vid! def look at a retune now you're running de-cat downpipe. Your tune may require more fueling to keep up with the extra flow now!

@megalodononwheels Год назад

Thanks man 🥳 The tuner did look on his behalf but could not find any problem with the software. So I am still a bit in the dak but spoke to a car shop and they think I must install a mini CAT on the rear O2 sensor as it is not made to receive info so quick without a cat. Its like all the air just gets blown past it. It will be my next step as it is not to expensive

Is there a difference between logging turbo pressure data when the car is on the road and when it's in parked and just pressing gas in idle? Most mechanics run the diagnostic on my turbo with the car parked, but most of the people run the car on the road to log pressure.

@megalodononwheels 2 месяца назад

Maybe when they go into launch control they can see if the boost is picking up like it is requested to. But I would imagine doing a "dyno pull" on the road will give more data to how the turbo is actually performs.

I facing same issue on q3 8u with stock turbo. Turbo was rebuild and diverter valve and n75 was replaced. The boost sensor that you replace is the diverter valve or n75??

@megalodononwheels 11 месяцев назад

Yes I changed the N75 valave... But as you saw, still not fixed :( Butttttt... I found the problem, it was the MAP sensor. For what ever reason the wrong MAP sensor was in the car, I could see it because the part number was wrong. (an Friend gave me the correct MAP sensor)

@megalodononwheels Год назад

@@megalodononwheelswhich boost sensor is this? Where is it located? I’ve had my VW Touran 1.9TDI BXE PD105 engine rebuilt after a timing belt failure and the guy doing it has done some performance mods on the cylinder head. He has also cleaned all carbon off all parts not replaced, cleaned the caked up turbo vanes, replaced EGR valve etc. Anyways after rebuild we had a judder issue which got resolved when we realised two vacuum lines were on the wrong parts. We still have a boost/power issue, it’s not the same as before but should be better with his mods which he says on average add a 15-20% performance increase. We swapped MAF and MAP off an Audi A3 I have access to but no change

For TFSI Generation 3 can i put the same value in VCDS and hit the button TURBO?

@megalodononwheels 6 месяцев назад

Make sure you always hit the Turbo button :) Also in some cars the values in VCDS will change a bit but are still the same thing. As an example on my car the boost pressure is called charge air and on another Audi's it is called boost air. So your will just need to play around till you get it :)

@dominicgama3362 Год назад

Literally the problem I'm facing on my B7! 😢 Where are you situated fam? May I please use your cable to scan it again? I scanned it a long time ago with an OBDEleven and got the Overboost error. I just wanna scan it again and see if there's anything else.

@megalodononwheels Год назад

I am all the way in South Africa 🤕... Yea the dumb overboost 🙆‍♂️

@dominicgama3362 Год назад

@@megalodononwheels Haha I heard your accent and figured. I'm in SA as well, Midrand side.

@NiickNicholas 10 месяцев назад

so which exact part that you found out and changed that solve the problem mate

@megalodononwheels 10 месяцев назад

You wont believe it... The sensor that was showing the boost pressure 🤣 its called a MAP sensor... Turns out when I called the shop to hear if they have spares they gave me a product number. When i got there and gave them the one I had in the car they told me that the one I called for and this one is not the same. Turns out the one in my car was for the wrong car 🙆‍♂️
