Topic: boost pressure??
Hi!
I have fis-control in my audi rs4 b5 2001. I can see rpm and that stuff but I cant see boost pressure. I have tried to change many settings but it will not work for me. can anyone help me please

Re: boost pressure??
You can find the boost pressure in group 115 of your engine control unit. See here:
http://www.ross-tech.com/vag-com/m_blocks/110-119.html
The ECU gives the pressure as MAP (manifold absolute pressure) in mbar. So you might want to change that, so that you get the relative pressure like it is shown on most boost gauges.
This can be configured at SETTINGS -> BOOST:
Control unit: 01 engine
Group: 115
Unit: Bar (or PSI if you want)
Scale: Gauge
Now you can start a measurement. Make sure that the currently selected control unit ist the engine:
SETTINGS -> CONTROL UNIT -> 01 ENGINE
Now click MEASUREMENT in the main menu an browse to group 115.
To have quicker access to the boost reading, configure a preset:
SETTINGS -> PRESET -> PRESET 1
Control unit: 01 engine
Group: 115
Value: 4
View: Measurement (or boost or whatever view you want)
For some view you will also have to set the upper and lower limit.
Re: boost pressure??
thank you so much!! one more think, I want to have it like this guy have on the picture with boost and rpm. can you help me with that to?

Re: boost pressure??
The FIS-Control can only show one value in the upper screen segment.
The reason is, that in the B5 the FIS-Control reads all parameters via OBD. And there is only one OBD group accessible at a time.

but how did that guy get it? he drives a audi rs4 b5

Re: boost pressure??
OBD is not the only way to get data. The vehicle speed signal is also broadcasted on the CAN bus.
So technically, it is not a problem to read boost and speed at the same time. I already implemented this for the B6/B7, along with RPM, oil temp, coolant temp, fuel, intake air temp and torque:

I really would like to allow mixing of parameters from different sources. But the current concept of the FIS-Control is based on OBD groups, so this would mean some work to change it.
As far as I know, the B5 doesn't have many parameters on the CAN bus. Most of them are already shown on the instrument cluster (speed, RPM, fuel, oil and coolant temp), so this will not give much more additional info.
