Nah the video simply demonstrates that a flex fuel sensor can not distinguish between ethanol and water.
No big deal really, up to 8% water in the flex fuel mix makes more torque, higher octane, runs cooler, but that’s more than a gallon in a tank.

True. A lot of good info in that doc. particularly the factor of force in weight over the rear wheels to increase kinetic force vs static, and the different ways to look at diff gear choice to suit engine and driving need.
Good acceleration doesnt necessarily always follow an ill-timed torque dump.

This is a good article explaining torque and diff gears and dyno:

Guys the one thing a dyno does measure properly is torque, the one thing the ECU needs to do its job is accurate torque reporting.
Personally kW don’t matter, they are always an educated guess. Whereas you can rely on 1:1 non multiplied torque data from either source when plotted against RPM for realistic BMEP range given compression, fuel or…[Read more]

Torque curve:
Basically means it can launch from idle or haul up a hill at 100 mph in third gear, if needed

Let’s see the actual engine torque curve, please, so we can benchmark yoir setup.

Come on man, that’s all Max Torque at the wheels [uncorrected dyno rollers], don’t fall for that!
Check actual crank torque corrected 1:1 so we can see whatchu got
What’s the engine torque the ECU is reporting at which RPM…
Forget the wheel or crank HP we can work that out!

How’s your air con coping ? Are you running OEM pump?
It’s 38° here in Sydney metro avg off-idle speed 18kph in a 2100kg black wagon Waeco flat out to keep whites cool.
Before ethanol and VVT I used to feel pangs of guilt dealing with dead butterflies, bees and stuff off my windshield coz ma 700 CFM V8 CO2 generator, now…[Read more]

Same, with “really effective” cats in place there is some argument whether readings would have positive or negative effect post cats even (I believe there is less free O2 – richer than pre).
Threads in efilive, LS1, and turbo forums thrash out that theres less than 4/5th (approx) of bugger all in it.

pir4te replied to the topic Ideal O2 Sensor Mounting in the forum Tech Articles, Links & Calculators 8 years, 11 months ago
Yeah from efilive site worst case scenario is 1%-2% (0.01-0.02) and others swear nothing. Every tuner I’ve met uses contraption after the muffler in the tips.
