Hello,


now i have a 2.0 TFSI car with a garret turbo. The car was already tuned by a tuner. So now the customer comes to me to change a few setting. Turbo pressure, Lambda regulation. I read out the ecu file over BDM and modified it. Changed the turbo pressure from 1,45bar to 1,75 bar and the lambda values to lambda 0,83.

After this changes i write it back to the car. The lambda value is now so much better than before.
But the Turbo pressure is at the specified field still at 2550mbar and the actual pressure is one time 2700mbar and then goes down back to round about 2500mbar.

Has anyone an idea??
May i forgott anywhere an limiter?

For password please PM

You can only request up to 2550mbar..

There's loads, and loads, and loads, and loads, and loads of threads about this! :)

What can i do to boost it up??

This does not apply to MED9, it is much easier on MED9 actually.
Probably out of reach for most people though.

Can you help my? I need to find the map sensor map...

"Out of reach" meaning that you need to fiddle with the ASM code?

Obviously.

3bar sensor is easy enough.

Thanks! That was what I thought. Got to get started learning that sometime soon.


Yes, that is piece of cake, but thread starter obviously already have that. ;)

You can run more than 2550mbar without changing any of the processor code too. Just that anything over 2550mbar will be open loop so you lose some of the protection features.

O = requested
P = actual

This is an example of open loop without changing any assembly.

Much better to say is - you can run above 2550 mbar without boost control.

If you do this, you should run a mbc in parallel to the N75 set to a safe value.
Use the N75 to control the boost up to 2550 mbar, and after that max the N75 duty and use an MBC to limit the highest possible boost.

Much better to just do an asm modification.

Would you mind giving mor infos on the asm mod that is required?

Please i need help.... The boost is not going over 1,5 bar...

I am facing the same matter as you. The fact is that you have a Boost Limiter un ECU on 8bit and the max value he can store is 255(2550mbar if you include the factor 10). So if you want to run more you can go open loop (without PID help but you can have too much boost as PID won't react to bring pressure back to 2550 ), or you can modify the ASM to change pressure factor and allow to run twice much (5100mbar e.g). This is what I've understand!

Actually you can find many thread about the 5120 hack on me7 this is what they are advicing you to read.

Hope it will help you,

What I don't get about running more boost than 2550mbar without 5120 hack is how you get that boost?

Requesting more load than the equivalent to 2550mbar? doesn't seem to be the solution, because these logs show always 191.7%
It's by running tons of deliberated overboost?

I just don't get it... for sure it's simple. Any of you mates could explain this to me?

BTW, that's not WG DC it's engine load ;-)

This is WG DC, this will obviously be dependant on what turbo you are using and what actuator.
