Gas Up, The 2018 Dodge Demon Will Have A “Race Gas” Tune

If we just all send a letter to Dodge’s marketing group telling them this was an impressive campaign, can it finally be over? Actually, yes, because by the time our letters got to Detroit, it would be April 11, and that when we finally get to see the 2018 Dodge Demon in New York at the New York International Auto Show. So we’ll stop whining about teasers and just give you the facts from the latest (and blessedly last) Dodge Demon teaser.

We already knew the Demon came with some sort of golden ticket to get a fancy crate packed with tools and what we believe are skinny front wheels, but apparently that big box also includes a tune, in the form of a Direct Connection-branded powertrain control module (PCM) calibrated for high octane fuel. Dodge specifies 100+ and never actually calls it race gas, we’re guessing that’s an EPA walk-around. So, if we understand correctly, from the factory your Dodge Demon will sip 91-octane like a normal performance street car, but if you get your special crate, you can plug in the option to run higher octane, with a corresponding performance bump. Dodge says, “The switch to the Direct Connection controller enables the supercharged HEMI engine to extract the maximum power from the knock-resistant high-octane fuel by optimizing spark timing. Drag racers will see big changes in elapsed time (ET) with the high-octane fuel.”

Don’t worry if you muddy up your tank with both regular and high octane though, the Demon is smart enough to know if the octane is too low, and won’t let you activate the high-octane function. It does this based on feedback from the knock sensors. We do have one question though, due to this line, “A message in the gauge display tells the driver the car will use the premium fuel calibration until the engine is shut off and restarted.” Does that mean that if you’re racing this thing, and shutting off in the lanes that you’ll have to remember to press your high-octane tune button every time you start up? Maybe all the cooling they’ve been bragging about means you can sit idling in the staging lanes.


Oh, one more little jellybean of info in this release, the Demon will have two fuel pumps, as opposed to the single high-volume pump in the Hellcat, and larger, high pressure fuel injectors. So whatever fuel you’re running, you can move a lot of it.
