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.

jadams161 · 06-21-2022, 07:34 AM

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.

HB E90 · 06-22-2022, 12:11 AM

My car doesn't like v10 either. My issue was the boost was just plain slower to come on. Felt like I had a slight boost leak or something. As soon as I went back to v9 it was good again. Leaving it on v9 2+ 91 with a little E85 to help with the Cali 91 fuel. Runs great this way. * Edit just logged a few runs. Boost rides above target for a bit. It really likes this map as do I. A few timing corrections along with boost spike and TC but only after a shift. I can live with that I think.

Let me know if something doesn't look good. BTW I just replaced the HPFP so it feels stronger now.

That's the plan it drives great I just wanted to know why. I figured it might be good info to have if I get a custom tune or big single etc.

Custom tunes will pretty much always be better than any OTS maps, if I recall correctly, OTS maps are essentially a one type fits all map that works fine on most vehicles not all.

Guys Ive gone back to stage 2 map. 93 octane tune. My car feels absolutely awful!!

I don't understand why my logs look ok but driving the actual car feels terrible!?
