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

[schwartzmagic]

Well, I finally got a real TT225 MAF and Sensor hooked up. Maybe today I will take a drive and do a few 3rd gear pulls and after doing so see how the car idles and also how block 32 looks. Also I have a spare ECU which I might decide to get Unitronics to put on the Big Turbo file for 630cc Injectors or I might just get a bigger turbo. The Precision CEA Dual Ball Bearing 5558 Turbo for better spool and response.

Dont waste money on the 5558.... Get at least the 5858.... They both spool the same, the latter makes more power.

so now i try to open eurodyne flash and it says account locked, down load latest version. i click ok, and nothing happens, i uninstalled and reinstalled from his website and still same thing......anyone having this happen??

[NJ1.8T]

It happened to me yesterday actually. What I did was sign into Eurodyne and downloaded the file again, it asked me if I wanted to delete the old file which I did and then it installed the new file. I went to my download folder and just sent it to the desktop where it worked for me.

yeah i did the same thing and it still doesnt work

ok tried again and this time it downloaded 4.3.2

Quick question about Boost Duty, What would happen if you increase the cell % in the early stages of the cycle up say 5% or so and leave the late just the way it is. I'm thinking the first 5 cells from top to bottom.

[Rac_337]

Anyone have experience tuning a b5 s4?

having an issue on a friends car with a tial 770 kit. keeps leaning out up top. requested lambda is .81 but its still going lean. 95mm MAF scaled using the spreadsheet.

[Rac_337]

guys i need help.

laptop crashed during a flash, now theres no info on the ecu and it wont let me reflash. what do i do?

Call Chris Tapp. Send him your ECU and cable. Be sure to include the appropriate international paperwork. It's 4:30- he's in till about 5.

im in toronto. hes only 3 hours away from me.

will call in the morning.

its for a friends big turbo s4 btw not my car.

Is your hardware capable of meeting such a demand?

Has anyone had success using the injection correction map for dialing in there fueling? Previously I was using main fuel correction. Just got my car fired up again, done a few days tracing and logging...still got a few to trace yet but not sure I'm getting the results I want.

[Budsdubbin]

main fuel correction should be used last. injection correction should be used to correct nonlinear injector response. Neither of these should be touched until you get your maf calibrated for your particular setup. But yes the trace feature should work because it would be giving percent correction values. 1.0001 would be the multiplier so if your lambda is being corrected for +10 percent to achieve desired lambda you would fill that cell with about 1.10. There is no "trick" or calculation for using this map.

Capiche....I still have not installed my V8 MAF so mafless, just don't have the funds to get my piping chopped/welded adjusted for the huge ass diameter. I always had PERFECT results with main fuel but am trying injection correction since it has been deemed "the better way"

I may have been jumping the gun..I will know when I flash my latest tune--as it seems my histogram corrections have settled down a little bit. I was worried as I was seeing very large corrections and did not have corrections coming in so high on my old tunes. I'm seeing corrections needed as high as 1.25 (this is after I smoothed and bumped some stuff down) which seems high. 1.25 in select areas not across the whole map--I believe IC is close to dialed as I was only seeing -3%. Main fuel correction is zero'd out.

I guess what I'm asking is what is an accetable % increase? Is 1.25% ok? Seems high, what do you guys have in your tunes??

I guess the problem is MAFLESS so my corrections will be more significant since the ECU is guessing.

[Budsdubbin]

I would start off by dialing in the alpha n map then dependant on how your o2 corrections are behaving. Injection map should be for the fine tune. Maf and or alpha N / throttle vrs pedal position mapping should be your base coat. Then clear it with the injection correction .

Also your alpha N map should be dialed in when your injection map is 1.0001 so there is no multipliers screwing with your calibration. Although you will have to do this in open loop operation. So to make things easier on you just tune the injection correction map for the time being. If your getting really bad correction like 10 or more correction in some places you have a bit of work to do on your alpha N.

[Rac_337]

Has anyone had success using the injection correction map for dialing in there fueling? Previously I was using main fuel correction. Just got my car fired up again, done a few days tracing and logging...still got a few to trace yet but not sure I'm getting the results I want.

after tuning my alpha n, i've only used injection correction for fueling, with the exception of full load areas in the main fuel correction map; i've added a bit at the top.

heres what my injection correction looks like:



the only time i see corrections dip rich is on increasing loads, but for some reason the vvt accel and decel maps are far different (richer) than non vvt maps....still trying to figure out how to mend this.

[torkme]

Need a little help.

1.8 T with a GT28R forged bottom end bigger injectors ect ect.

The tune is spot on, I got the O2 correction in check, the AFR's are 11.5 to 11.8 under WOT. Car runs and drives great under part throttle or daily cruise.

Here is the problem. When I go into the torque table and shut off the 100% load for timing adjust, my idle timing shoots up to 45 degrees and when ever I give it throttle it brings the timing down to 3.00 or less degrees of timing. I don't have any knock (1.5 max) to speak of. WTH?

Problem, when I give it WOT hit 100 load, the timing dumps to 1.5 degrees. I know how to adjust the timing map and I know how to make load changes but from the looks of it nothing I do makes the timing change when I hit 100 load. I cannot turn it off because it causes my idle timing to freak out and all the part throttle or WOT timing tanks.

If I could get the timing issues addressed the car would be making great power. Any input would be greatly appreciated.

Thanks!

[TooLFan46n2]

Thanks for the input guys. I totally did not even think about ALPHA-N. On my old file it was perfect. I changed the VVT settings across the board so I will look into what affects ALPHA N & VVT engagement/disengagment are having. Part throttle seems to swing quite a bit. I'll often see corrections jump/swing wildly up to 20% just holding a constant 5% throttle cruising. My fuel trims are OK but can get a better 3 & 7%. RAC337 thanks so much for posting your map. I was getting corrections in the 1.2x range and was getting concerned.

Buds, I made some formula programs and the KPA to load conversion does not hold out for me above 5000 RPM. However this may be due to running MAFLESS and maybe the ECM is fudging the equation up as my calculated torque seems to take a hit in this area as well.

THe car is damn fast though. WAY faster than the original files that came with Maestro. And the torque maps are much better tuned...I'm reaching desired timing pretty much everywhere where previously I couldn't hit anything in the midrange/spool area.

[ANT THE KNEE]

I'm on the fence with going Maestro due to rumors i've heard of probs with deletes. I have no cat,sai,maf,n249,etc and need to be able to pass inspection. Can anyone out there confirm or deny? NY inspections are a PIA. Also are the base file upgrades free(ex:going from 630's to 830's, upgrading throttlebody)?

It doesn't matter what software you run, you'll have the same issue when it comes to emissions testing.

What did you change to hit your correct timing levels. This is where I am having problems.

This is simply not true.

I live on Long Island with Maestor with none of the above mentioned emissions parts on my car. They plug me in the computer and all tests come up as passed instantly. My friend & I both have Maestro and all the deletes on LI and haven't had trouble passing either car. I don't even resistor things off or run a rear 02 sensor...

The whole idea behind maestro is you change it all yourself so to answer your question- you pay for changes with your time and learning.

I believe the issue has more to do with how the emissions tests are carried out. Some people have problems in some states whereas others in different states don't have issues. I'm not an expert, just going of what I've read regarding the experiences of others.

Seems we live in the same neck of the woods(i'm 5 mins from the coliseum) so the emissions are the same. I now feel at ease about converting from Uni(since i have there delete file). I was asking more about the base tune files they have. Do they charge for it each time? I understand the fine tuning is on me. Just trying to get a whole picture before i pull the trigger,and i'm unclear

nice to see a solid answer about guys passing smog with Maestro. not that my car will get smoged any time soon if ever again..... but now i know someone has passed w/out any issues. now if i could get a 2nd license to use with my cable so my DD could get tuned.... wish maestro 7 was like efi-live were all i needed was to pay for a license to tune other cars i own.

Another solid answer my friend: It is. $450 for additional licenses on the same cable IIRC.

All of the tuning is on you and the selection of base files is free straight through maestro. You can change base files as many times as you'd like.

[NJ1.8T]

I finally started to get the tuning down a little bit after getting help from a bunch of guys on here, Budsdubbin, Ruben, Rac 337, SGTphatboy in which I appreciated very much. I just spent over $10g on the turbo setup and was finally getting to enjoy driving my car again as the cool weather started to really make the car respond until yesterday. On our way to the 2nd Annual OctoberFest at Black Forrest Industries here in NC. I was with agroup of about 15 cars and while driving we merged into another two groups of about 30 cars. Enjoying the cruise and about 5 miles out from the event traffic came to a sudden slow down and then to a stop. The next thing I notice and feel is my body getting blasted forward and then jerked backwards. Well, not sure if the car will ever be the same, the rear is pretty bad on the passengers side all the way up to the roof. I only took two pictures before I was taken to the hospital. I am ok, just some whiplash and body pain / aches. Anyways, here are the two pictures of the damage. Bumper is pushed in especially under the trunk and the side is pushed in and crumpled.

From this:

[sabbySC]

That really sucks, the good thing is that you are okay.

[NJ1.8T]

I'm still in alot of pain today, two days after it happened. But I will say, the Jetta sure did save me. I have seen other cars bumpers and trunks get pushed right into the rear seats of cars. I just hope that it can be fixed thats all.

That really sucks, the good thing is that you are okay.

[TooLFan46n2]

Can anyone who actively traces logs answer a question.

When power enrichment is active (targeting A/F from power encrichment map) do the cells highlight in PE during log playback. Mine do not. My cells in the FLL map highlight even if they are not being used for target A/F. For some reason I used to think they PE highlighted or has it always been this way? Wondering if this is intentional or a bug. Thanks.

[TooLFan46n2]

Here is my current Injector Correction. This is the 10th revision with hours of logs. To me it looks horrible, the car doesnt seem to stop wanting fuel. Taking more logs with this map enabled praying it levels out but I'm not to confident. Anyone else have corrections this wild? This is on 630cc injectors running 22-24psi mafless. Block 032 -1% and -8% last I looked 2 days ago. This is smoothed out alot, it wanted many initial corrections like 1.35xx. Any thoughts?

[Budsdubbin]

You shouldn't see corrections of 35% corrections in this map should be + or - 10% tops. You are looking into the wrong map. As said before you will have to be looking at your alpha N. Also reset your fuel trims your bvc or IC may need attention. IDC good?

yeah you have a lot of highs and lows with that. too wavy. i'd agree with buds and say you need work to alpha n as well.
