all modern cars, their seals and lines can tolerate e85. Only reason why manufacturers “prohibit” is because they don’t want you tuning (accessing fueling and other tables in the ecu) your car and potentially get fraudulent warranty claims. Understandable, but some people don’t care about that.

check where the thread is at. Ecoboost. Next, show me where we are looking at mileage. I said power. Alcohol is better at making it.

that’s because Subaru engines can barely stay alive under stock power

This post is about making power. It absolutely does not suck if you're trying to make power. The octane rating alone, especially the intrinsic octane when directly injected, makes it a very viable option for power. At 50% levels, you just can't get it to knock even at high timing and boost...

I'm getting the hybrid for the wife, but I'm actually pretty interested in who want's to start modding and tuning out their ecoboost mavericks. I hope you guys get aftermarket support for tuning the ECU and we see people swapping turbos, bolt ons, and alternative fuels like ethanol Edit: And...

I would have hoped they would do multiple otherwise the data is moot. But if the author is biased, he did a poor job at convincing.

Turbo timers are a thing of the past IMO when turbos were only oil cooled and lubricated. Almost everything out there is oil and coolant fed.

Also while you are correct. Dyno conditions do generally...suck. Doing back to back pulls, there is a lot of heat buildup. And even with fans, it's no replacement for unlimited ambient air at 70+mph.

Pretty much. The modern ECU and the logic is amazing at keeping engines running well while being efficient. Still makes me wonder why some people like their carbs and rotary ignition.

Same logic applies. Towing increases stresses usually in the way of more heat through increased load. Hence why the towing package includes things to reject more heat to ambient. But really you'd want either a logging device or an ability to see real time if you're seeing knock-retard. Or...

Are go overall averaging a cheaper price when using ethanol free? There's no disputing you will get slightly more MPG on ethanol free since ethanol is less energy dense.

There are many tables that impact a timing table. Knock sensor is just one. Knock sensors have gotten better, but the logic is still pretty similar. The goal is to not heavily rely on just the knock sensor because it's riskier. My goal when tuning cars was to have no knock in regular...

Because when the created a base timing map they used premium. Anything less results in the knock sensor retarding timing.

I never said an engine would know what octane is being used. I said engineers use a designated fuel as a starting point for building timing maps. For the 2.0t we would expect premium, and for the hybrid, I would suspect and expect regular. And yes if you have extreme conditions where timing...

We talk a lot about compression ratios in this which is absolutely true, but you can't forget the timing curves based upon load, RPM, IAT, etc, since timing stresses the fuel a lot and impacts efficiency. All cars will have a base map of timing created using the intended fuel (I think we are...

I can't really get OE parts for my 27 year old Civic that I had from the dealer either. Most everything was aftermarket at that point. You could find new old stock on ebay sometimes. But OE parts will dry up after a certain amount of years. It's normal.

this.

Pressure on the headset isn't an issue. So many people transport their bikes this way. Easy.

Hard to know. Depends not only when you ordered it, but options, how many are in front of you at your particular dealership, etc. I ordered on 6/17, yet there's people who ordered in July who've been scheduled.

I generally take the height of the vehicle (68.7") subtract the headroom (40.3") and then subtract 1-2 inches for the headliner to get a baseline. If you do that you get about ~26". Obviously this isn't perfect since a car is not a perfect box, and maximum height may not be over the driver...
