View Full Version : Upgrading Injectors and FPR before k04 Flash

12-10-2012, 08:10 AM
So I have had my k04 in for about 2 week and I'm still running my k03 software (1bar). I am waiting for giac to email me back so I can send off my ecu for the pc-16 upgrade. I got my 315cc injectors and 3bar fpr today and I was wanting to know if it's ok to go ahead and install these with my K03 1bar, and k04?

from my understanding you do not need to upgrade your fpr. i just purchased a franken kit and a few people told me i didnt need to change it. however i have a 01.5 so im not sure if that would make a difference on stock one. but i prolly wouldnt do injectors until you have tune ready to plug in.

I agree, swap in the tune and injectors/fpr at the same time. A 2001+ car with a wideband o2 sensor can kinda get away with it because it can adjust the AFR at all times. Your AEB can't do that and will probably run quite poorly without the correct tune.

The injector/FPR need to match the tune you are running, so you want to change them when you put the new tune into the car.

That's what I thought, but just making sure
