I'm in the 2nd group and can't wait to see how things go with the 1st batch.

[QUOTE=AVOturboworld;655423]Sorry we haven't been giving much updates, it's been a busy week for us, but that's because we are getting ready for the Tokyo Auto Salon from tomorrow (Friday, Japan time). We've got our car and the white DAMD Turbo A/T to prep, along with everything else going on.



@AVOturboworld
Holy crap that front bumper is sexy! What is it? Also in light of heat discussion... how's the A/T holding up? Any chance of some more footage of the damd car, maybe an interior from a dig?

This statement worries me slightly... So if I have a cat-less headerback exhaust then I run the chance of overboosting the stage 1 kit? If so then would you say that the stage 2 kit should fix this issue? What suggestions do you have to solve this potential issue?

for the guys who plan to remove our 2nd cat initially, what other boost spike management parts are there, either as part of the base system or as an upgrade if our driving style is heavy footed? I cover a region from SoCal to Seattle.

same as Previous post, what parts get added into stage II and what will it cost me?

also, I wanted to know, with either system what if any warranty there was as this kit is at the top of my turbo kit list.

thank you.

[FasterpromsFRS]

wasnt he just implying because of the extreme cold air?

I'm not 100% sure if you guys are aware but the original question that I asked about over boost was due to extremely cold climate where the air is far more dense, from what I can understand North Carolina doesn't seem to go below 10°C (50°F) very often, my question was specific to air that is exposed to tenperatures of -20°C to -30°C and below, (-4°F to -22°F) therefore I don't think this would be an issue for you if you removed your 2nd cat. As for Seattle and SoCal, I'm not very firmiliar with the weather conditions there..

Ah. Thanks haha just found the thread about it. Couldn't see NEAR that small on my phone. I like it

The original question was about extreme cold conditions on the stage 1 base map, the original tune that we ship with the kit.

But - it's worth saying that if you make any major changes from a stage 1 setup, get it re-tuned! Removing the secondary cat and going catless or with a high-flow cat, is going to add 1-3psi of boost at upper rpm's, and I would insist on a tune for that if you do so.

Once you've gone FI on the FR-S/BRZ, it falls under the same set of rules as, say, a Impreza turbo or an Evo turbo model. Any major changes in the system needs a tune to correspond to it. That's because any change can result in minor to major changes in PSI at the engine.

At the engine is the key phrase here. Turbochargers are simple air pumps, not really that complicated. But if you measured PSI at the turbo itself, and then at the intake, you'd find two different figures. Piping to the intake, the intercooler, and even the design of the intake will determine how efficiently the engine gets that air over the rpm range. So 5psi at the engine may be 6psi at the turbo, for instance. And that's a fairly efficient system.

Then backpressure in the exhaust determines how well the turbo is going to do in the upper rpm range. Our base tuning map is designed around 4-5 psi range in the upper range due to the backpressure of the secondary cat, but if you went with a full catless exhaust, suddenly you've removed that backpressure, and now the system wants to go to 6psi. Nothing actually wrong with that, it's going to feel great! But the tune was not designed for that.

It should be mentioned, though, that 5-8psi is the figures we are talking about. This isn't a 20psi build that's going to spike to 24psi, this is not a high pressure solution for an STI.

If you are planning to remove your secondary, get it tuned for a catless system. That's all you need to do to.

Stage II is still not set in stone at this time.

We do warranty the kit itself against defects.

I apologize if this question has been answered previously.

In the future, is there a possibility for AVO to provide base maps for cars using high flow cat (300 cell for example) and aftermarket exhaust?

My target purchase date is still another 10-12 months from now.

Yes, we'll be working on base maps for a full turbo back exhaust as well, that falls in line with the stage 2+ maps.

[Huehuecoyotl]

Can you be more specific when you say you do warranty against defects. what if it breaks?

Well say for example another setup proves x miles over y time. That makes it harder to buy this kit but shopping is easier then..

The conditions of use on avoturboworld.com say three months. Just wanting to know, not trying to stir anything up or be called a troll. Obviously it's a mod, I expect to pay to play.

Just when we talk of boost spikes etc, I drive often from Washington to California. When stuff happens, just good to know the terms. I know avo from back home. Big name. Still, terms are terms.

At this pricing it really doesn't matter. Can't get turbo for less
