	Siemens DEKA IV 630cc on Rs4 551k « on: February 13, 2016, 03:07:54 PM »

Hi, actually i have a tune 460ps on my rs4, any problem but i would like to put Siemens injector instead of rs4 oem for more fiability, i already put a bosch 044.

I just have to modify the krkte value?

I just want to change injectors size, no more modification.

Thx and sorry for my english. .

You can (usually) get away with simply changing KRKTE for the 630cc siemens, but they suffer from QC issues and you may experience idle issues....

which means one or more of the following:

increasing torque reserve
increasing idle rpm
disabling (or numbing) low load misfire detection

I can make you calibrate the injectors Siemens 630, but would need your software to the base calibration

You do not have 460bhp on std rs4 injectors.
And you can not just change to Deka 630 on your current tune and hope everything will be fine even getting KRKTE wright.
You need to retune that properly.
