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

[elRey]

My instincts are telling me it has something to do with your returnless fuel system. What did you do with that? And is your base tune for a returnless system or a return one?

[TooLFan46n2]

For the guys running the base Eurodyne 630CC file..


During your logging at what boost level have you seen knock starting to show up? Through my logs running 14-17ish psi I have no knock. I have the boost set @ 19psi-20psi now (T3/T4 50 trim) and I started getting 2.25 degrees on cyl #2. I assume this is still within acceptable parameters but should I physically be able to feel the engine getting this knock because I can feel a very slight letup in power during this point. I'm still combing over the logs but I believe actual A/F is still matching requested.

**And do I have a correct understanding of this? It is indeed knock or is it timing pull? Is the computer actually backing off timing at this point? Could I be feeling something more than just knock like my fuel pump is hiccuping?**

[elRey]

The value you see is timing pull, not knocking itself. And yes, you can feel it when ECU pulls even a small amount of timing under heavy load. The very, VERY cool thing about this software is that you don't have to compromise. I.e. either live with the slight drop in power when it pulls timing, or lower timing globally (unisetting) and thus lower power globally.

Now you can examine your logs. Identify at what load/rpm you are seeing that timing pull and just lower timing in that small area on your timing map.

So great!

how do you swap between maf and mafless?

im thinking im going to go to a DV and maf instead of the mafless BOV i have now

On my '03 AWP you just unplug the MAF. If it's plugged in it will use the sensor, if it's unplugged it will rely on alpha-n. per Mr. Tapp

U guys think 100 octane is enough fuel to switch to the " high octane timing"

[derekb727]

switch. do a log and see how much, if any timing is pulled. thats basically all that is different between the two from what i could tell. chime in, im sure there is something different, haha

i switched on 108. same amount of timing pull. but timing was increased across the board.
i wish i would have ran on the pump file and logged. there might not of been any timing pull...?

Use the best of both worlds...MAFless with a diverter valve. It is honestly the best way to go. Since I ditched the MAF I will never go back. I attempted to run with a BOV for a while but it really just was not that tuneable on my setup.

Ive decided to go with Forge Supersize valve in this setup. Have you got any experience with this?

Hi guys....would like to ask you a few questions...if this is off topic please erase it

I really don't know nothing about engine tune (just play sometimes with the timming), I can do 2 things...one go for the BT 630cc Uni file or go to Maestro 7..I really like the idea of the Maestro 7 but I'm a bit worried on blowing up the engine...or never reach a decent behavior of the engine...I know they give you a generic file to start, but...how hard is to learn this thing and to understand...I'm an average guy with average IQ, with average everything..hahaha...

The question is...."Is this going to be a pain in the ass for me???" (this is the most important question)

Hope you could help me...

I'm building up my car with this stuff:

SETUP
VW GOLF GTI 1.8T AUQ ENGINE 2003

Kinetic T3 manifold
GT 3071R 63ar
Precision WG
Siemens 630cc
Walbro 255 LPH Fuel Pump
CTS 3" DP
Titanum Vale Springs
Iconnel Exhaust Valves
JE Forged Pistons 20mm
IE Rods 20mm ARP bolts
FMIC
AEM meth Inyection
FX 400 6 pads Clutch
42DD 3 "Catback
CTS 3" Downpipe
Metalic Impeller Water Pump
Beru Coils
BKR 7E IX
AVC-R

Thank's for anyone that could help me on my choice

if you feel that a full adjustable unit is over your head. Well then get the Eurodyne tune and if down the road you fell you want to try it out. It's only a few more coins to add it to your system

Yeah in my experience and what I have seen as long as your running stock throttle body, intake mani & displacement the stock 630CC file is pretty spot on.

hey guys just wanted to post Maestro has another update

HURRAY

did they revert the update? i see last one being 10-8

[2literA2]

did they revert the update? i see last one being 10-8

^Same???

[One-Eight GTI]

If you go to the Eurodyne Forum Chris posted a new update from 1.8.1 to 1.8.4, due to the fact 1.8.1 doesn't automatically update??? I haven't tried to download it yet

[weenerdog3443]

^Same???

come on fellas.... you update it through flash and maestro now remember

[Dub-Nub]

come on fellas.... you update it through flash and maestro now remember

dam forgot lol, whats the update on this?

Here you have it Dub...http://www.eurodyne.ca/forum/viewtopic.php?f=18&t=770

come on fellas.... you update it through flash and maestro now remember

Wouldn't update automatically... must do a manual update to push this one thru.

[Dub-Nub]

I NEED 2 STEP ONLY!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

More then a couple people have requested this, i cant believe we still dont have it =/

[RoloGTI]

A new Eurodyne owner here, hope everything goes smoth

Were I can find the SW to start learning it (Maestro 7 and the rest of the SW)?

Thank's

yea if the speed feature worked on it we we be set

[Dub-Nub]

anyone know if its okay to unclip rear o2 sensor on a mafless file? dont want to leave it dangling when installing wideband.

[One-Eight GTI]

Hey Dub-Nub you will be ok, Mine had been disconnected for awhile now, Put my wide band sensor there for my air fuel gauge

[Gulfstream]

I was thinking of doing the same, but Autometer instructions is 5-6" downstream from turbine. Do you get reliable readings that far back ?

[One-Eight GTI]

Yeah I actually do, My downpipe was made by Al, so the second sensor spacing isn't that far behind the main O2 sensor... Works great, just disconnected the 2nd O2 sensor and tucked the wires away...

Edit I don't have a cat either, But I'm sure you figured that

[Dub-Nub]

Just finished my wideband install. I disconnected the back o2 sensor and left the second half of connector in that black box under, same place where i hid the aem wideband connector. Had a tough time figuring out why my gauge was going ALL over the place, it could make it dance by wiggeling wires. turns out one wasnt set correctly, so i got that fixed. now it should be fine.

Im getting the kit from Al as well so Ill prolly do the same. Did you cut the wire to the 2nd O2 or just leave it under the car?

[One-Eight GTI]

I did the exact same thing as Dub-Nubs post directly above yours... Hid everything in that little black box where the connectors are for both O2 sensors

[Budsdubbin]

I've been trying to control boost with the n75 and have been failing to do so. Using the quick settings in the flasher I reduced boost to 20%, according to the boost desired its supposed to be held at 17psi but I keep hitting 22-25psi. When I hooked up line pressure to wastegate again its limited to wastegate pressure which tells me that the line doesn't have a rip in it. I thought maybe there was something that I would have to do to switch the n75 on but there isn't. I've tryed swapping n75 valves with a friends and it still is the same. Do the quicksettings not work for boost? Do I actually have to fix the duty cycle mapping?



I'm still having issues with idle. After a while of sitting the car will almost fall on itself for a split second. This happens when the 02 correction starts to happen after sitting. Idle will bounce and so will vaccum while it will correct up 23% and below -16% and it will occur in the same block while viewing the main fuel scale in maestro. As you can see in the graph for some reason the value for actual A/F will stay at 58 for about 15 seconds while cruising. I think I'm gonna try swapping out 02 sensor 1 to see if thats the issue.

[Chunki84]

If I buy new ecu and
buy eurodyn maestro 7.
I can do immo defeat my self?

[Budsdubbin]

Yes.
