thanks for checking it out, it's a phoenix intercooler, it was on the cheap side for IC's.

Also about to install some new injectors (from index 7 to 12) NGK 1 step colder plugs and the bimmerlife coil kit, will do a few more logs after, could be interesting to see if there's any change

Thank you 👍🏼

How many miles on it and when did you last walnut blast?

Ps, watch that large timing corr in cyl 4.

Uhh Cylinder 1?

69000 miles currently and walnut blast was done around 53000 ish, I fitted an catch can about 5000 miles ago

there are 2 logs on there, not sure which one people are looking at, I'll try to rename them

Gotcha. The one i looked at, cylinder 1 had 8 degrees correction and 4 had none.

[danthomoo]

Rb pcv was fitted last week too, and as of today new index 12 injectors, just waiting for the bimmerlife harness to arrive

yeah both logs are quite different, just slightly concerned the degree of correction, I always use vpower which is 98 Ron, I've changed the map to stage 1+ on 95 Ron to allow some wiggle room, will do anther few logs over the weekend and see

Hey guys please look at these two logs. I am bone stock n54. I am trying to figure out if I have to adjust my front actuator arm. Because of my WGDC and spool time I think my boost is building slower than it should - can anyone verify this?

Solid. I was just curious if there was any easy reasons on the table for cyl corrections still but I think you're good. Might just be getting close to threshold for your fuel type without a custom file.

uhh if you scroll slightly up, you'll see its been resolved. thanks douche

well thanks to both of you! You were both right and you both have tought me something to look for on the logs, let's keep this forum friendly

absolutely! I thought about the fuel and that maybe Shell are lying about their Ron rating, I'm hoping it was a dodgy injector and that as of today with my new index 12 versions it'll resolve, will post up some new logs over the weekend, thanks for your input mate

Maybe they didn't look at it.

This morning the car started, sounded really rough, and then died on me. I had to give it gas just to keep it going, and then I drove to work without an issue.

So far it's just been misfire codes, I previously had seen some low fuel pressure injection cut codes.

Here is my most recent log. This was sitting at a stoplight and then pulling off in drive, not a very hard pull or anything. It does seem like I'm getting big timing corrections on all 6 cylinders:
https://datazap.me/u/eyehategod/idle...?log=0&data=14

Yeah, its pulling timing pretty bad mid range.

But you also want to get a shift in there - thats when corrections and basically timing recovery (which is kind of dme dependant) are at their worst - Looks like this log is like up to 5300 in 3rd.

Run it to 6250 in 3rd from about 2500 and shift into 4th and run it to 5500.
That will put a good load on everything.

Are these one step colder NGK plugs that are fresh?
What type of fuel is this? Dont use just grocery store. Try for Texaco, Mobil/exxon, conaco, sunoco. or shell.

Be interested if they new injectors helped out. Same tank of fuel?

just pulled 2 more logs, seems much better with the new injectors, 3 degrees on cylinder 1 on the 2nd run, more corrections on the first, be interested to see what people think
They're certainly no where near as drastic as the first 2 runs with the old index 7's.

I filled up with a bit more V-power from the same station, only difference is new injectors and a warmer day today

Hello,

Still trying to find a technical explaination to my WGDC drops prior WOT ?

https://datazap.me/u/studio54/drop-w...data=2-3-23-29

Does anyone know why WGDC banks spike down prior WOT ?

Is this normal ?

High or low rpm, everytime i touch my pedal to WOT, my WGDC first goes down to 25-30 before going up to the max... why this extra travel ?

Thanks !

In all seriousness, it's because of you.

WGDC goes from default position (high) for no-to-low request (stop/cruise) with no boost request, to higher request, but still no positive boost target, so it opens to offset. Finally, back up a lot with active PID when higher request/positive boost target hits. That's an extremely watered down synopsis, but is the gist of it for what you're concerned about.

The DME is not doing anything with BCS that it's not programmed to do for the conditions and real-time data, so the bottom line is that you draw that WGDC curve like that on the chart by how you drive while logging.

Why don't you try throttling up and maintaining speed in the gear to where you want to start logging from instead of coasting down from a higher speed at 0% accel pedal and then flooring it? It's only a "drop" because WGDC starts high because of your 0% request. If you were on the throttle prior to going WOT, WGDC would start low and that drop would be a jump instead. Off-throttle WGDC isn't going to change what it does on throttle, it only changes where it's starting from.

Hello,

Thank you for your answer.

I did this special log to point the drop, but on my normal "logs", cruising/maintaining at 2600 rpm then WOT, it does the same thing.

Example :

You're welcome. Right, it was dropping from 60%+ to 25-30%. Now its 40% to 25-30%, a much smaller "drop" and then spool mode activates. As I said, what it goes to on throttle will not change much, that's baked into the tune and there's a small variance depending on environment, setpoint, MAF, options, etc.

Any stage 2 should move to similar position depending on conditions. From a page or 2 back, has a "drop":

https://datazap.me/u/nichender/log-1...2-30&zoom=0-37

Next log from the same car, little to no "drop" because starting WGDC is at nearly the same level:

https://datazap.me/u/nichender/log-1...2-30&zoom=0-34

The important thing to note is that they go to 25-30% initially no matter where they are starting from, just like yours. I can only assume you have rattle fix set, which just makes your starting WGDC that much higher, further to move and always "down".
