Joining you from the nearly dead 1 series forum. I have a quick question about MHD. Can install a first time tune with error codes. I have an adaptive headlight warning. Carly liked to "fail" and make my dash a light show. Also, I would like to get my logs interpreted when I feel confident these programs can be installed and used without major error due to the current condition.

DME codes that appeared when i scanned were: 29D2
Shadow codes were: 2AD0, 29F4, 29F5, 2AAF

Swap plugs/coils to another cylinder and recheck if misfire follows, if it still stays on cylinder 6, then swap injectors and see if it follows again.

You can install and use MHD with existing fault codes if that's what you're asking.

MHD won't make your adaptive headlight fault go away though. You need to find out what's causing it then fix it and clear all codes.

If someone has time to take a look at 2 current logs I just did. Having a weird oscillation at the beginning then boost builds and its gone.

Your tuner should be able to help smooth it out. Happened on my custom tune as well, after a few revisions smoothed out.

He says vacuum leak. Which might be it. It developed after I changed vac lines and added a Tial bov with the VTT throttle body adapter

Right, have you checked all the lines, connection points?

Yes, I replaced all the stock rubber lines. I am wondering if a failing boost solenoid could cause this issue. Looking at the log, wgdc bank 1 is going crazy and so is the throttle...until rpm comes up and boost builds. If a solenoid was failing maybe it can cause this issue without a code....

Possible solenoid issue, log WGDC both banks and see if they both have the same fluctuations, if its one bank, swap the solenoids

HI can someone take a look at my log and tell me how the turbos are doing in terms of being max'd out? These are PS2 high flows. We may have reached their limit... these are race heads with port job.

Yeah looks like you've pretty much maxed out those turbos 95% WGDC 25psi

Yea I think some of it is that the heads are race ported, so for a stock head that would be more like around 30 to 32psi. I wonder if they're being pushed too hard....? Maybe should dial it down just a tad? I will say, I don't go around doing pulls all the time... I only get on it like once a week maybe... depending on how many mustangs are around

What could be causing all the timing corrections?

Common causes are fuel, plugs, coils, injectors etc

Yeah 95% WGDC is too much, probably best to dial it down. You self tuning?

No, I'll inquire; also, which column shows the air/fuel ratio in the log?

Lambda banks 1 and 2 AFR

I am not sure what is going on with my 135. N54 6mt. I took the following logs just driving home from the supermarket. I would just tap the throttle lightly and it would surge like when I had m mode enabled which I hated.

Stage 2+ v10. Jb4 and no lift shift relay installed but it's been installed for years and is in map 0.

I'm not sure the best way to narrow down what is going on. At high rpm's if you take your foot out of the pedal it's surgy/jerking like it's doing something too rapidly no matter what I do with the throttle, on or off.

This is my first log I bought the monitor module for this issue, so if I need to do anything differently please let me know.

new tune if anyone could take a look and give their thoughts. I was having horrible throttle closures and overboosting/oscillations on a previous tune.

The log is a mess. Did you do it correctly?

Monitoring in MHD? DSC completely off. Kick down disabled (AT only).

Rolling in 3rd gear, 2500 rpm, mash WOT to 6-6500 rpm, shift 4th for a few seconds and then let off.

No. It's 6mt and this issue only happens driving "normally" like a civilized person. It also is 100% resolved by going back to v9 maps and only happens on v10. Frustrating but at least I know it's not a hardware issue.

This was a log of me driving to and from the store gently on v10

If it's resolved in V9, just use that map.

Not all maps run great on all cars, you'll find some OTS maps run better than others.
