Maestro DIY Tuning Help

Would be worse if I couldn't fix it.

LPFP questions.
I have a full PR fuel system (450, line kit, 925CC mpi) installed (unwired) and I'm planning to switch from Maestro to UM or ecutek to actually run it. I have a 1.8T

I'd like to be able to drive the car when I put the turbo back on to make sure everything operates correctly before switching tuners (especially since I'll need to drive it if I go with UM).
I have 3 LPFP tables - "Max LPFP duty", "LPFP duty (4WD)" and "LPFP duty".

Any suggested baseline changes that I should make for the PR450 so I can drive the car and what do I need to look for (since without MPI there's no low pressure sensor). This discussion (https://www.golfmk7.com/forums/index.php?threads/maestro-diy-tuning-help.364083/page-26) talks about tweaks for a 525, but only the 0 column.

Sam tuned me with the DBV2 V2, but at the same time I'll be switching to a V1 and I'm not trying to waste his time doing revisions back and forth.

max 75
11 first column both tables
75 last column both tables
That should be able to get you to start it up and idle and drive around normally.

 

[Diggs24]

It'll surge around a bit when you first fire it up. That's normal.

75 last column both tables

My last column is 95
My second to last column (700) is from 72 to 95
My third to last column (600) is from 60 to 95
and my 500 column is from 53 to 85.

I'm assuming if I'm going to set 75 as the new max I would need to scale it all appropriately?

[Diggs24]

yes
you could probably leave them alone as is if you aren't going to go WOT. What you are trying to avoid is too many amps going to the controller. It won't command 95 duty just driving around so it's a non-issue.

 

[joedubs]

If I do give it any more than half throttle it'll only be to see how it spools compared to the V2 did - and it won't be over ~4krpm.
But again, it's mostly just so that I can actually drive the car/function test/etc prior to(most likely) bringing it to UM to get tuned.

Thanks @Diggs24

Need help: 2 logs below. Both are half pulls, just to see how the V1 spooled. Slider is set to 20. Towards the top of 2nd I'm hitting 27.5 (look at that rail pressure). Seems to hold target in 3rd much better. Hits target wastegate position so I would think the wastegate targets need to be changed, but I need assistance.

I can post the tables I have available, I'm not sure if I have everything you gti/R guys do.

More background:

I'm on the tune that Sam did for me when I had the V2. We always had a little boost creep in 2nd but had decided not to bother dealing with it since I would be switching tunes. Now that I have a smaller turbo and I'll be running it a while longer for some reasons out of my control, i would like to try and fix it.

Edit: Went back a few pages and I see that nobody seems to have any idea how to control boost on the non BT files.
Bummer.

 

[ZuMBLe]

Your "overboost" really isn't that bad, only 1 psi. I would consider that within acceptable spec? Slight drop in rail pressure but still within safe levels also. You could just lower the torque request table from 450 to 420 if you're concerned. That would be the simplest way to bring it back in control without seeing your whole tune.

 

[joedubs]

Look at the 2nd gear log
I'm requesting 20, hitting 26+, and rail pressure dropping to 140k

Unless I'm reading it wrong.

 

[ZuMBLe]

Damn.. I didn't look at 2nd gear because I consider it a pretty useless gear because of how fast the car revs through it. You definitely have a problem there. Cut torque request to like 400. Geez...

Bummer.

The factory boost control logic/tables uses axis' of "intake flow factor" and 'exhaust flow factor"...the problem is you can't log that in Maestro.....fail. So going to the boss loader files which use RPM vs airflow or MAP or whatever is more straight forward. From what I remember guys were generally just adding or subtracting 5 or 10 percent or whatever from the factory WG table and crossing their fingers.

"best" solution would be get something that can log what you need, like the Ecutek dongle, and then tuning/tweaking it should be pretty straight forward.

Do you know of anyone who has successfully logged a ED Maestro tune with the ECUTek dongle?

 

[aaronc7]

It's came up in a few UM threads and it works for them. ED doesn't change the basic software version / ID so it should detect the ECU/DSG just fine. But no I have not done or seen it first hand.
