I purchased my car (non x50) with a (1.0 bar) flash that the previous owner could not give me any information on.

I would like to data log to make sure it is running safely.

Can anyone recommend which actual values I should data log with the Durametric to make sure this mystery flash is running safe?

Thanks!

 

You should log Air fuel (lambda) from the 2 banks and at full throttle it should be between 11.5-12.5

The durametric will log in lambda,just multiply this with 14.7 and you'll have the correct air fuel ratio.

 

From the Actual Values List would these be:

Lambda setpoint B1

Lambda setpoint B2

or

Oxygen sensing, bank 1 Lambda Value

Oxygen sensing, bank 2 Lambda Value


Thanks.

 

would also look at timing, load and IDC.

 

Oxygen sensing, bank 1 Lambda Value

Oxygen sensing, bank 2 Lambda Value..
Do a run in 4th or 5th gear from 2000 rpm till redline..
When you made the run push export button and save the file,now you can see data in excel...

 

I appreciate your response .

 

What is IDC?

 

Injector Duty Cycle.

You may also want to crack open your ecu case to see if the main 44 pin psop chip has been soldered on before (see pic).

Many european tuners solder in a encryption board with their logo. If its been soldered and there is no board, its most likely upsolute.

 

Thanks Tony I will check it out.

If it turns out not running safe can my car be re-flashed with a safer tune?

Also which Actual Values combination do you recommend I run?

Thanks!

 

Great info, I have a similar situation on my Turbo S, I think I have an FVD flash but am not 100% sure.

 

I believe that with FVD, they keep track of the VIN of the cars that have their flash. I think that Rhonda@fvd on this site can check that information.

 

parameters i log when i need my tuner to check are

oxygen sensing bank 1 and 1 lamda
ignition angle
engine load
rpm
boost actual sensor
