I ordered part number 0261545074. We will see. I was planning to get 0261545053 but it is supposedly the same but for a cx7 idk..

Interesting you can still get the 074. I thought that one was discontinued. Anyway keep us in the loop.
It's a cheap part so we will see. More just curious if it truly will work hahaInteresting you can still get the 074. I thought that one was discontinued. Anyway keep us in the loop.

I'm interested to see if it works. It says is a 200 bar vs the oem 140 bar. In theory the scaling is different. Hope it works.
Well if it doesn't work I'll be switching it out for this one instead.

Ok so sensor # 0261545074 did allow my car to run but my Short Term Fuel Trims were -25 and my AFR at a partly warmed up idle was 12.5-13.5 ish. I ordered # 0261545053 now from Summit Racing so we will see if that changes anything. Good news is I have figured out a custom tool design that works perfectly to remove the sensor without pulling the intake manifold. Homemade and quickly done but you get the point haha
Fuel sensor is a 27mm or 1-1/16" either/or. Cut a deep well socket and then just tack welded the adapter on similar to a crow's foot design but a thru-socket style. Side note as well, the sensor was shaped slightly different but seemed to seal well still.

Yes they were and I done a boost leak test before all this and did find a couple small leaks that I fixed. It is possible I had those during tuning so then fixing them would make the tune off a little. I didn't upload the datalog that I took earlier. I didn't necessarily want to idle my car until fully warmed up with it running down at 12 afr and then have fowled plugs to add to my list haha I will upload koeo test tomorrow along with the idle log.
My pressures were around 750 and only 130 degree coolant at that time. Thursday I should have the new sensor and I am just hoping it fixes my issues! Originally my idle pressures would usually be around 450ish so....yeah idk what that necessarily means but ever since these issues it has been upwards of 7-900 at idle instead.

Ok so I swapped out the sensor today and I also got a warmed up idle log of each. I will say they are both rich still and not sure if it changed anything lol Both might actually work but I am thinking I must need a maf cal again or something for some reason. I had an exhaust leak at the turbo to downpipe vband that I fixed a while back but I didn't ever think it was that bad to affect the tune this much. I will take it for a test drive today and see what happens. Here are the two logs.

Your fuel pressure sensor reads 0 volts on both logs. I will strongly suggest to check your harness again. You may have an electrical problem.
Seems odd What is the voltage labeled under because I didn't see it in the datalog parameters? Also, how could it be receiving 0 volts but still sending a signal for the pressure it is reading? Just seems odd. I didn't see an option for the sensor voltage on my AP for data logging choices.

So I guess I'm dumb lol I read this like 3 times but are you basically saying that the log just might not be recording what it is actually doing pretty much? From what I understand the most sensors use a voltage range to get the reading or vise versa so I just assume if it were reading 0 volts then the pressure readings would be the same?..

Every sensor only supplies voltage. It would need some kind of embedded controller to provide a final value, which means it would need to be programmed.
The cost for even basic sensors with this kind of configuration would be insane, and you'd need specialty tools to tune them.
Basically, doing a "MAFCAL" would be prohibitively expensive.
So, BMW will have this feature next year (Apple already does).

Oh ok gotcha. Yeah sounds expensive for sure. The more complex stuff is usually means the more often it has to be fixed lol

Correct.
I try to stick with the "keep it simple, stupid" type thinking and try not to overcomplicate stuff haha
