K04 Conversion sensors swap
« on: May 29, 2022, 09:45:39 pm »
Hi, guys! Hope it's all good with you all!

So, I've started to do K04 conversion on my GTI. The turbo is fitted already and it's coming turn for the injectors.
But I'm not sure and I wonder, should I change the rail sensor with 200bar when it is on easy access, and it's same question for the Map sensor. Or it's better to leave them for the maping session?
The car currently is on K03 Stage2+MAP

Thank you!

The standard GTI rail pressure sensor is fine, but fitting the K04 3 bar MAP sensor is a good idea. 038906051C.

Thank you!
So I will leave the fuel sensor how it is. But if I change the map sensor now, is it gonna work with the current map till be mapped for K04.

Change it on the day of the mapping. It's a 5 minute job to swap that over.
