I see timing corrections but don't really know how to look at logs yet. Should I go back to stage 1 until I get FMIC?
Also believe I have a few leaky injectors(most likely the couple rev9s I have with my rev7) as a couple plugs were wet when I looked at em while changing coils.

Definitely need a larger FMIC, your IATs climbed quickly. Boost slightly off target, but not enough to lose sleep over.

Mod up and show us what she can do

Yeah I saw that also, all 3 logs I've done have had the lpfp steady at 55psi. Any idea what could be up with that?

Yes sir, walnut blast and FMIC are next on list now that all maintenance has been taken care of.

The fuel pressure sensor under the intake is bad. Mine did the same thing when it was busted. The old design is pretty cheap, but prone to failure due to vibration. Newer design is about 2x more expensive if memory serves me right. Me being a cheap bastard and the sensor relatively easy to change, I opted for the old one.

Here's the link to my thread on replacing this part, which includes the old PN

Thanks for the info, I'll look into getting a new one ASAP.

Just did some logging on the weekend, would appreciate someone having a quick look

Stock 08 model with MHD syage 1 map, running 98Octane fuel in AUS

about to install 7"FMIC, RB outlets, DCI's, new plugs and coilpacks, also thinking of vanos solenoids as I've got intermittent Vanos codes coming up

Only looking for input on LPFP and HPFP. Im told my HPFP cant keep up. This logged threw a SES light and required a restart. I've had several instances of my LPFP dipping into the high 40's but the HPFP always stays 1400 or higher. I was under the impression that anything over 1200 for the HPFP is fine.

Please dont post if you're not sure. I dont need advice on the other parameters. I just want opinions on the HPFP really

[GearHead335i]

Finally got some data logged in, how is mine looking? I'm looking to get a custom tune, would That be an option or just stick to OTS? The boost target said that it was 11.4 and mine was 10.4 on manual log and then when I hit auto logging and it's just the two gauges it can spike up to 14 psi. Does the manual logging just read differently?

Took a couple of logs. l'd appreciate it if someone could check'em out. 30FF thrown both pulls which I was already aware would happen just not sure of the cause yet. Looking to see how the car is running and any advice is welcomed. Thanks!

Looks like Cylinder 1 pulled timing which in turn caused wastegate to open up a bit and drop boost. Even before that boost versus target was off by ~2PSI during the pull. Looks like you could have a leak somewhere. On a positive note, IATs were good the whole time

Suggest you max our performance with FBO and OTS tune before going custom. You're IATs went up pretty quick, if you haven't already upgraded your FMIC, you should consider it. Boost was off target by 1-2.5 PSI at times. Not sure what's up with that. No throttle closures or crazy timing adjustments, so fix that boost and FMIC and keep at it.

You had some throttle closures due to overboosting. Could be lazy boost solenoids or worn waste gates. Bank 2 is pulling out a lot more fuel than Bank 1, could be nothing or leaking injector(s) weak spark.

Thank you for taking a look. I did notice the correction in cylinder 1. On the second pull there was also corrections in cylinders 1,4,5. Not sure if you looked at that one? I'll Probably end up taking it to get tested soon to find the leak.

Your waste gate DC drops at ~5300 RPMs on both charts. On 1 chart this could loosely be correlated to the cylinder 1 timing pull, but not on the 2nd chart. Not sure what is causing this, but once you get it figured out, I'm sure the motor will feel stronger.

Thank you for taking a peak at where I'm currently at! Have a brand new front mount in the trunk ready to install, only a cxracing but it will to the job for now. And to my knowledge after the fmic I will be FBO?

I did recently replace 1 injector bc it was leaking. Before I spent $1000 on 3-6 new injectors I purchased a refurb index 4 injector but did not get it coded. People on here say you won't even notice a diff if they are the same index but I'd say it wouldn't hurt to get it done? Does anyone know how much bmw charges?

why 2nd gear? Car went EXTREMELY lean, that's why it went into limp mode

How does this log look?

What he said.

lol dude, in it's current state your car is a disaster and all you're interested in hearing about the is the health of your HPFP?

Instead of callously disavowing information that's actually way more imperative than your initial requisition, try increasing your level of rational next time.

Notice how both fuel banks are not hitting 234.95, at zero pedal? > leaky injectors.
Also some high timing correction and stock ic?

Could they be leaking and show no other symptoms, car runs perfect

I'm confused, is this directed at me?

Please, enlighten me, how is my car a 'disaster'?

He's probably referencing your overboost problem and massive timing corrections

Then 'He' doesn't understand the question regarding the HPFP.

This is a small piece of a much larger log and I'm only interested in input regarding the HPFP

The car is fine and I didnt ask about the 'health' of my HPFP or your assumption of the health of my car. I asked what safe operating parameters are for the HPFP when going WOT but I guess I didnt make it obvious enough for you. I guess I should have highlighted this part:
I dont need advice on the other parameters. I just want opinions on the HPFP really

You should spend more time understanding request/questions you're replying to rather than jumping the gun and spouting off at the mouth trying to make someone look bad when you don't fully understand the situation.

You can speak as eloquent as you like. It only makes you come off like a pretentious ass but I guess most people on this board know that already. Congrats!

Why are you bitching on people trying to help you out? Your data log looks like dog shit, what do you expect? Your HPFP looks fine, the rest is not. Is that better?
