Maestro 7 Tuning: FAQ, DIY, hard data, and advice thread

[a4e3y5]

You select the appropriate vvt enabled base file from the drop down menu. Check the base files for one that is suitable to your needs.

Not sure im following u. I open maestro, click open file, open whatever file i have and then left side of the screen fills with options (fuel, timing, etc). Did this but didnt see anything that says vvt..

Anyone have a 630 file that gives you early boost and boost throughout the RPMs. I'm looking for a file that can get me my early boost so I don't have to wait till I hit 3500 rpm range to feel my boost or feel the car pull. I have no power down early on just when I hit 3500 or more is when the power comes on.. I have the Precision 50 Trim .48ar Turbo and Precision 39mm Waste gate.

Any and All Help would be greatly appreciated.

Click select base file, which will be found below open file but in the same menu(at bottom of file menu if I am not mistaken). Than select the appropriate base file.

Maybe try a different turbo

Maybe. But first he should try selecting the "Cam timing map" from the left-hand menu. This will bring up your VVT control map.

It may not be the tune. What size is your IC plumbing?

Thxs guys! I'll ck that out and report back.

X2. That's pretty much how my 50 used to behave when I had the .48ar. U can also ck for leaks, but for the most part, that's the way it is.

[NJ1.8T]

Its the Kinetic Kit which I believe is 2.75 -3" IC piping!

It may not be the tune. What size is your IC plumbing?

[Three3Se7en]

My kinetic kit has 2" hot side and 2.5" cold. Hope this helps.

[NJ1.8T]

Its the kit that cam with the CTS Turbo MKIV Kit. It probably is what you have. I just wish there was a way to get a little better response earlier n the boost range! Maybe I can bring it to someone who does Maestro Tuning on a Dyno and see what they can do!

Can increasing the Compression Ratio or Timing get the 50 Trim to spool a little quicker?

[Rod Ratio]

Yes.. throwing timing at it will help spool somewhat. The 50 trim is a lazy Turbo however, and the spool you're seeing is normal.

If you want faster spool; switch to a gt3071

[screwball]

The VVT stuff's supposed to help, but yeah, you're looking at a new turbo if you want better spool. Even a BB CHRA would help, but it's about a grand just for that on a 50 which puts you near new 3071R territory.

[NJ1.8T]

Thanks Guys, Appreciate the input. Well just picked up the car today after they finished putting in the fuel pump.
Anyway, I noticed that on my Boost Gauge at idle I am running around 10-12 HG. Isn't it suppose to be around 20HG or so?

OMG.. pressure test that sucker STAT!!

[a4e3y5]

Just downloaded the new 630 file (VVT) and noticed some of the maps are quite diffrent....am I seeing rite?

[NJ1.8T]

Where can I go to get pressure checked. Do any stores have something I can buy to check it? This is my first Big Turbo and well never had any problems with the KO3s which always stayed right at 21-22HG

OMG.. pressure test that sucker STAT!!

[a4e3y5]

^^^most likely a vacum hose. Thres a DIY where u can ck it urself. i believe is a the top of this forum (stickies)

[Brah]

You can tune it all you want, but it's not gunna change that much. If the IC plumbing is that big it's gunna take a while to spool. That's a lot of volume.

I use 2" charger pipe and 2.5" throttle body pipe. My 50 trim spooled to 22psi by 4200. Like stated before, its a lagy/lazy turbo.

I switched to a bb 6262 and it spools close to the same as my journal bearing 50trim. A little later, not much tho

[SGTphatboy]

im wondering if i should try another base tune. still running really rich and still no help from chris tapp. driving 4.5 hours to rennen performance to see if they can help me next week. if we get no where on the dyno with tuning this thing, im selling it. pretty frustrated
thank rac_337 for helping me as mush as you have, i owe ya a beer

[NJ1.8T]

Anyone ever have there Wastegate Hoses heat up to the point they become brittle and break. Mine just did now I am trying to figure out what kind of hose to get and how to protect them from the turbo heat!
Anyone know of good hose that won't melt, heat up and become brittle from the heat? Where can I get it?

that same very thing happened to me recently. i just wrapped it in heat tape, havent had an issue since

[NJ1.8T]

What brand of heat tape did you use? Thanks for your help by the way!!

Install a maf bro

I use Aeroquip pushlock hoses and "dash" fittings from the turbo, wastegate, and N75. Never had an issue

[screwball]

how did a 6262 get compared to a 50 trim?

[screwball]

I've gotta have hardware problems cause my car no likey the VVT_SEM_70mm_630 file at all. 15:1 at WOT-22lbs before I let off.

[sabbySC]

Mine doesn't like it either. Stalls when coming to a stop, idles to rich, and is generally not that great. If you want i could send you a copy of my current file to try out.

[NJ1.8T]

I can't get the Switching active to stay on. when I check the switching box it says code doesn't match, certain features disabled. Chris sent me a new code to try but still the same thing. I just can't figure this out!!

[screwball]

Sebastien, I'll shoot you an email dude.

S4 maf is in, I had to hack up part of Arnolds purdy inlet on this PAG setup, I hope this thing helps

I'm curious myself, keep us posted

[tojr1088]

try resetting all the corrections maps. i noticed alot of em are modifed on that file. and try lowering the exhaust temp threshold for full load lambda. i noticed the vvt file has it almost 300 degrees higher and the power enrichment maps are different so maybe lower that to have full load lambda working. also raise your minimum pulsewidth i noticed its like .34 when i checked but other files its like .75

also the bvc table is way different than the seimens default values.

good luck!!

[NJ1.8T]

Has anyone tweaked the 630VVT File in which you have a smooth idle and also power early in the RPM Range? If so would you be willing to let me try that file? My email is nc18tdub@gmail.com

Would really appreciate it if you could send me the fiile just to see how it runs on my 1.8 Jetta.

Like I said in your other post, check block 032 and adjust BVC and IC accordingly to help idle out... You have a 50 trim now not a KO3, your not going to get instant boost this has been covered... I'm assuming you have Maestro to make these adjustments..

Read this to help adjust BVC and IC, its been covered a million times

first block in 032 X Injector Constant = time in MS.

the 032 block is in %. You injector constant is in ms/%. so..... % x ms/% (%) cancels out and you're left with (ms). This method is ONLY for adjusting Voltage Compensation.

The second block is simply scaling your injector constant by the second value in 032.
Example... 032: -1.875 +5%
Original hypothetical Constant = 0.05000

-1.875% x 0.0500ms/% = 0.09375ms <===== subtract this from your BVC table.

5% = 0.05

0.05 x 0.05000 = 0.0025.. 0.0025 + 0.05000 = 0.05250. <==== your new Injector Constant.

[NJ1.8T]

I really wish I knew what all that means. I am use to just having a GIAC file but when I went with the 50 Trim I got Maestro so I can learn how to tweak and make it run better. I'm just trying to learn about it and how to do things. Thanks for your input. I guess first and foremost I should bring it to my closest Maestro dealer which would be EuroWise and have them Dyno Tune it for me so I can see and learn what can and can't be done.

Honestly the IC and BVC are the most easy things to adjust, trust me... But yeah a dyno tune would be a good way to go

The only thing I recommend is make sure your car is good hardware wise before making adjustments to BVC and IC... Thise vacuum leaks you have had will throw everything off.. I would reset your fuel trims by disconnecting battery or reflashing your base file in again, now that you think you have your vacuum leaks taken care of leaks taken care of
