Visconti Tuning STG1 Flash (EcuTek RaceRom)
 

Just finished tuning a 2009 370Z with EcuTek RaceRom on MR Performance's Mustang Dyno in Westbury NY.

Rememeber... these numbers will break your heart but gains are nice !

This car has a muffler delete and HKS Intakes

Enjoy!

can you tell me more about this flash? is it just plug flash and good to go?

Looks like 15-20 hp power gains. Impressive.

Nice Job Visconti :tup: looks like some good gains.

You already know I am waiting for the Ecutek Jon.

Good gains for sure. Nice work!

JV, is that the new dyno y'all installed? Looks like a nice set up!

BTW, good job on the results, as always!

So... What all was done in the tune, just fuel and timing changes? Any VVEL changes?

What supporting mods?

The supporting mods are actually in the first post !

HKS Intakes and muffler delete.

Changes to the tune:

1. Raised Rev Limiter
2. Speed Limiter Removed
3. Fuel Map Changes
4. Using EcuTek's RaceRom Ignition Timing Control

Thought it was important to show what kind of gains could be had with just the correct ignition control.

So No changes to the VVT or VVEL.

With the in house testing that was already done there are gains to be had with VVT changes and will be showing that on the next dyno session.

Sweet. Would be nice to see a datalog showing timing on stock pull vs timing on tuned pull, just for comparison's sake. I'd like to know how much timing advance was added.

show us a dynograft with only the timing change
because what I see is an untuned AFR which was probably the stock tune Vs the tuned AFR+ignition

I remember when I did my intake manifold swap testing that alone with AFR that wasnt as far off as yours in the dynograft your showed us, ive seen around 12whp of gain which would have been more with a baseline of 10.5afr at 7000rpm . and the guy that was running the dyno was impressed at the second pull saying WoW ! you must have adjusted the ign timing with the afr.. which I didnt...


but im glad there is finnaly another company comming in the 370z ECU market !!! good job ;)
Hope you guys do something with the HR engine !! hehe

I dont mind* posting up dyno sheets but I'm sorry I dont post up datalogs

The factory timing strategy on these cars are slightly influenced by AF changes but nothing that would show a huge gain or loss..

So changing the AF ratio will actually effect the amount of ignition timing the car will run.. we're talking .5 degrees of timing.

I played around with A/F mixture and didn't see a huge different in WHP.

On 93 octane this is the AF ratio I will be running, 91 octane will see something just a tad richer.

My car !

For anyone interested, visconti did an amazing job, i been driving the car today and throttle response was notticable... no more bog before revs. I reccomend going to him to get this tune !

this is also what I found out with Uprev ;)
btw, its not because I mention Uprev that I have to owe to them , If i could and be a possibility I would ditch it for a proper control over everything.

I totally understand..

UpRev is actually really good software.

EcuTek is just going to take the 370Z to the next level

-John

nice gains, just wondering why weren't the VVT and VVEL not tuned at the same time?

I think they just wanted to see what could be done with purely timing control. And then later, see if VVEL tuning provides gains.

+1

Agreed. I used UpRev a lot on my Pontiac Solstice. Loved it! Use to data log all the time till I had ever inch tuned exactly where I wanted it. :tup:

PM me for the tune $?

ok, good to know that. I meant if they can tune the VVEL now, why wait for another time when the car was sitting on the dyno. Unless they need to do more testing with it.
But either way more kudos to Visconti and EcuTek to provide another EMS option for the VQ community. :tup:

Very interesting. With uprev it seemed that there wasn't much gain to be had with additional ignition advance...

Really looking forward to seeing effects after VVEL tuning.

Was baseline with mods but no tune?

Yeah, UpRev, I believe, updates the ignition targets but still allows the factory nissan advance/retard algorithm to handle the pursuit of those targets.

I'm guessing ECUTek replaces that algorithm with a more conventional "I tell you to do THIS, you go and do THIS" style system.

With out giving too much away EcuTek has been very successful in the GTR and Juke market because they understand the ignition strategies in the nissian ecus... So although UpRev changes one of the ignition maps.. The one they change isn't always used.

Anyways EcuTeks Custom Ecu code called racerom can high jack any input and output in the Ecu .. So we have full timing control with a fully functional knock control system.

John

One simple question. UpRev or EcuTek? And why?

:hello:

Also, when will you guys have results after VVEL tuning?

sub'd!

John,

Do you have any logs to post in csv or raw? Particularly that show the timing curve?

Asking a tuner for datalogs is like asking a chef for his recipe. He won't share unless he's an amateur :)

He's got nothing to hide.

Not really. Asking a tuner for datalogs is like asking the chef for nutritional facts about his food.

May be insulting, but it's not going to "give away his secrets".

This is all I wanted when I asked for logs earlier in this thread.

I want to see a datalog supporting their claims that they have unimpeded control of timing and compare it against my own experiences with UpRev.

The nutritional facts are posted in the first post ;) You're requesting datalogs which will reveal his ignition timing tables aka recipe that got him to these results.

The analogy is getting worn out now, but now, those charts are like taking a bite and seeing how it tastes without tasting the alternative first.

Those results mean nothing if he didn't try with UpRev first.

Plenty of people get huge gains over un-tuned with UpRev and have for years.

Timing traces on UpRev all kind of look the same with this car.

Showing the timing traces during those pulls to be significantly different from what can be accomplished with UpRev will prove that this software has a leg up. Otherwise that's just another dyno graph showing that a tune helps make more power, which is a given.

There is no secret to timing. You add advance until you get knock and then back it off. We just want proof that he's actually able to add that timing. Words are wind.

Also, this is spoken like someone who really doesn't know much about how tuning these cars works in the software out there.

I'm not asking for screenshots or dumps of his tables. I just want to see what the car actually did with those tables.

Totally different.

I am not trying to give John Visconti any flack if the tool works or not. I just want to know if it really does have timing control. I am working on a few things for the shop car that this could be big part making some serious naturally aspirated power. If you don't have timing control you can completely forget it about it.

From someone who has probably seen more UPREV datalogs then anyone in the country, I can see from the dyno graph that the ECUTEK def has timing full timing control. As soon as we get one in here within the next few weeks I can elaborate more.

Vince

This is good to hear other people are having and seeing the same things I have been.

^^:tup:

maybe I've to visit you Vince for a Ecutek tune.
