Hey guys,

Following up with some logs for review from my previous post - 500hp package - N54Tech.com - International Turbo Racing Discussion

First is a typical WOT 3rd gear log. Everything feels normal.


I have been getting some light rough idle / possible knocks during cold start up after the c@t warm up when the car kicks the idle down to normal. I've also sort of noticed something when coming to a stop and between brake to accel just before leaving a stop. I've got a second log that I'm hoping someone can take a quick skim for irregularities.

I have used INPA and checked most of my values, my main concern being injectors. My flow values are 2.20, (3) at 2.27, and (2) at 2.46 mg/stk - none of these seem too far one direction or another, except the 2.20 is injector 6. I have previously had some misfires before switching to my new plugs - my old plug wasn't wet to the touch, but looked to be like some overnight leaking.

Sounds like the injectors when you did the plugs were starting to leak a bit.

Let the car sit overnight & pull again and see...which index?

Unfortunately they're index 9, but only have 102,000km so I was hoping they're still in decent shape overall.

I asked a local BMW dealer and they said there currently aren't any SB's open for me to get a recall or extended warranty on them. I don't necessarily want to spend $2000 on injectors this year if I don't have to.

I do believe there is an injector sb

If you go on BMW-RP type in the last 7 of your Vin, see what’s open
