This is how we can safely run 87 in our cars. Sure if you want to race around or act like a fool premium would be better, but if you just want to drive normal like 95% of us do then 87 is fine! And NO premium fuel is not required...by law it would say so on the fuel door.

The knock sensor system enables the engine control module (ECM) to control the ignition timing for the best possible performance while protecting the engine from potentially damaging levels of detonation, also known as spark knock. The knock sensor system uses one or two flat response 2-wire sensors. The sensor uses piezo-electric crystal technology that produces an AC voltage signal of varying amplitude and frequency based on the engine vibration or noise level. The amplitude and frequency are dependant upon the level of knock that the knock sensor detects. The ECM receives the knock sensor signal through two isolated signal circuits for each knock sensor.

The control module learns a minimum noise level, or background noise, at idle from the knock sensor and uses calibrated values for the rest of the RPM range. The control module uses the minimum noise level to calculate a noise channel. A normal knock sensor signal will ride within the noise channel. As engine speed and load change, the noise channel upper and lower parameters will change to accommodate the normal knock sensor signal, keeping the signal within the channel. In order to determine which cylinders are knocking, the control module only uses knock sensor signal information when each cylinder is near top dead center (TDC) of the firing stroke. If knock is present, the signal will range outside of the noise channel.

If the control module has determined that knock is present, it will retard the ignition timing to attempt to eliminate the knock. The control module will always try to work back to a zero compensation level, or no spark retard. An abnormal knock sensor signal will stay outside of the noise channel or will not be present. knock sensor diagnostics are calibrated to detect faults with the knock sensor circuitry inside the control module, the knock sensor wiring, or the knock sensor voltage output. Some diagnostics are also calibrated to detect constant noise from an outside influence such as a loose/damaged component or excessive engine mechanical noise.

Most of these so called green technologys are not possable with out government subsities. Until we can advance green energys technology to the point where there can be a profit in it we are shooting ourselves in the foot. Let technology advance at it's own pace and we can all be happy.

Well put!

Just for giggles last night I did some cost/savings estimating. I figured a equally equipped ev truck will cost north of 60K. Figure in sales tax and I would be pushing 70k. And I feel I may be a little conservative on that price. For my particular situation, it would take almost 7 years to break even if fuel cost $20.00 a gallon. And that's not factoring in any charge rates or upgraded charging port...nothing. And since my wife works from home more now, it would take even longer for her to see any return going with a ev which she doesn't want either thank God. And on top of that, I have had discussions with insurance agents and they strongly believe that car and home insurance rates will go up as well due to how unstable these huge battery packs in the ev can become without any warning and next to impossible to extinguish.

The real issue is Electric cars are just as hard on the environment as fossil fueled cars. Hydrogen power is the way to go and is insanely easy and CHEAP. But you will never see it because they can't bend us over with it. The planet is covered in hydrogen.

What if you have tune for premium fuel and refuel regular 87...?
Is something going to happen?

Easy? Cheap? Someone is gonna make a profit on it! Safe? see Hindenburg 1937

First thing the tuner does is modify fuel and ignition timing maps.....I wouldn't use 87 in a car that's been tuned

I'm definitely not going to go to 87.
I was just wondering what would happen if it inadvertently got there.

[gtstorey]

A lot of tuners leave a low octane map that the computer will default to when enough knock is detected.

I had a 93 minimum tune for years. Now it’s flex and loves E.

Hydrogen in a usable fuel version is energy negative. Hydrogen makes sense if you have lots of cheap electricity, especially if combined with natural gas reserves. It makes little sense if you are in an oil rich nation with good refining capacity. For somewhere like Japan, it makes sense. For the US, it doesn't.

Electric cars may or may not be better for the environment, but they help in energy independence because you can make electricity from so many resources instead of being limited to just oil (and a smidgen of biomass). Coal, natural gas, "green", etc. Of course, then the question becomes can you be independent with all of the mineral requirements as well.

Never really complained about gas prices, especially since it just comes with the territory for these 6.2 monsters, but prices in HTX are close to $5 for 93, and it will only go up more. Makes me think twice if I want to drive the car or play around.

That is a excellent point! Batteries for these EV's as well as many other "Green" sources of energy such as wind turbines, and solar panels contain "rare earth minerals". Currently there is only 1 mine in the US extracting these metals (in California no less). Why? Because it's so environmentally destructive to access these elements! So what this green movement will result in is us being reliant on China (who could care less about the environment) and Russia (who is the world leader in nickel) So for us to become green, we will be at the mercy of our 2 biggest threats! The Liberal green movement wants to make you believe that energy independence will make us secure, but I disagree. Energy production will and did make us secure.

Absolutely!
