Visconti Tuning STG1 Flash (EcuTek RaceRom)

[visconti]

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?

[370Z JT]

Looks like 15-20 hp power gains. Impressive.

[Mr.Squeeze]

Nice Job Visconti looks like some good gains.

You already know I am waiting for the Ecutek Jon.

[MyKindaGuise]

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.

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.

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.

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.

[Megan370z]

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.

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.
