Bolt-ons + Tune Power?

I thought Visconti mentioned he would tune different NA parts.
Via Street logging for free if you purchased a NA STG1 tune.
Which would be great for real world fine tuning.

I could be misinformed.
Probably should let him speak for himself.

You might be right, but I still feel what Synack means is more like tuning sitting in the Dyno.

Or another way to see it, One gets Visconti's STG1, then buys all Nameless exhaust + intake antd they offer a ECUTek map. In that case you will be you will be paying for both.

But of course, you can just skip all this trouble and just get the cable, license and tune directly from Nameless.

[Synack]

Yes he tunes over the phone/internet but you have to pay the shop/guy/tuner you take it to for their dyno and personal tuning skills.

Like right now, I'm buying the Ecutek turbo tune which gives me the basic turbo tune for about 4psi I believe, but I am also paying my tuner/shop to use their dyno to fine tune for the other mods I have such as exhaust and other stuff, also higher levels of boost. People don't work for free lol.

Why is everyone so concerned about the tune of this thing with bolt on parts? Like VE tables aren't taken into consideration in the computer's calibration...?

This computer uses a MAF signal to determine airflow and deliver fuel and ignition advance based on load values AND the amount of air entering the engine. It's not a speed/density setup that requires a tune for bolt-on parts that change the engine's volumetric efficiency.

I've been running a mail-order rom tune on my 500whp sentra for 5 years. It was probably tuned for a smaller turbo, but that's the great thing about MAF setups.

I remember years ago on speed density setups having to retune after going to sea level or risk melting a piston. On my MAF cars, no worries. I can change cams, exhaust, intake manifold, without running into those issues.

Am I saying that a tune on bolt ons won't make more power than a vehicle specific tune? No. I'm just saying there is WAY too much importance placed on this issue. You could gain 2-4whp with a vehicle specific tune, only to lose those gains when changing elevation. Visconti's tunes are designed with a margin for safe operation. Changing exhaust, intake, or even cams isn't going to push the tune outside of its safe parameters. The MAF compensates for that.

Until these tunes push for speed density operation, I wouldn't be so concerned about specific parts altering the tune's ability to control the engine.

Someone wants to do before and after I'll get the dyno ... But you have to have my STG1 tune

I'm in for this when I get my SRT exhaust in. I spoke to Mo on Friday and he said it was going to ship on Friday or tomorrow at the latest. I thought I told him the resonator that I wanted but I didn't so he was waiting for me to contact him. (He posted in the thread to contact him if exhaust didn't ship yet, but I overlooked it.....ooops)

I could meet you at Nightshift, but it would have to be on my day off, usually Wednesdays. I'll contact you to figure out the logistics once I have the exhaust in hand. I'm having it shipped to my work address to avoid the issue of not being present for delivery so hopefully UPS delivers all the packages at once. Other members have received the packages on different days.

I also have a Perrin Pulley that we can test with and without to lay to rest any claims of added HP or no effect at all. It literally takes 10-15 minutes to swap.

Would we be able to use a lift to swap the exhaust or should I get my stands, jack and tools together to swap the exhaust on the ground?

Maybe i'm mistaken, but i thought i read somewhere in these forums that these cars come with ECMs that learn?

Reason i ask is i remember from my days of owning an MKV GTI that the days of having to tune every time you changes parts, fuel grade, etc, were over. If you had a tune, and you decided to change your down pipe for instance, then all you had to do was disconnect the battery to clear the ECMs memory so that the next time you fired it up, it would start slowing learning and adjusting parameters based on the MAF reading, o2 sensors, knock sensors, etc and you'd pick up a few ponies. Matter of fact, the only advantage to getting a stage 1.5 tune (for downpipes) was the increase in boost that you could take advantage of by freeing up the exhaust, but it wasn't a requirement.

The way i understood it from the tuners (APR, Revo, etc) was as long as you didn't make a modification that caused a significant increase in VE that went outside of the "expected" parameters in the computer, you were fine. Meaning that it could make small adjustments for intakes, exhaust, etc, but if you slapped a bigger turbo on there or swapped injectors then you needed a tune or the computer would freak out and go into limp mode. So if you have a stage 1 on this car, i don't see why you couldn't run an I/H/E and have the computer relearn and take advantage of the new setup. Unless your intake screws with the MAF readings that is. I'm I wrong here? Visconti or other tuners can you clarify?

Am I missing something here?

I have the stg1 tune, as well as the P&L catback, midpipe, and crank pulley (despite the agency power thread, no actual HP gain). I will be getting a dyno run in this week, as well as a new intake, tune, and dyno next week. There is also a dyno of my car in stock form floating around as well.

Within 10 days or so, we should have a few solid numbers for boltons and tune (sans overpipe, and header).

[JimmyMac]

How do you like the P&L catback? Your setup is close to what I will be running soon.

There is nothing to be gained by tweaking the tune after putting the exhaust on.

If you fit the car with a good exhaust system you'll make more power.

Some intakes might need a map tweak but we'll cross that bridge when we get there.

Currently I dont see any need or any gain by changing the intake.

I really like my setup. It's got a bit of pickup, and the exhaust sounds great. I've put over 500 miles on the exhaust since installation, and it's starting to break in nicely. The tone is a little richer now than when it was first put on.

I do have an extra part or 2 they've yet to release, but those should be out soon.

when will the BRZ get a reflash? almost the same car the ecu is that different?

Same ecu, I already sell a reflash for it.
