Video summary
The video showcases a significant breakthrough in tuning the Frostbite engine for the FIC 2150s truck, which is now running exceptionally well on E85 fuel. The narrator expresses immense excitement as the vehicle performs flawlessly during various maneuvers, noting that the engine feels "spicy" and ready for track use. A major highlight of this update is the dramatic improvement in reverse gear operation; previously, the truck would stall immediately upon releasing the reverse button, but now it backs up smoothly without dying, a change the creator describes as the best part of the entire project so far.
Beyond the driving dynamics, the technical data confirms that the tuning job has been successfully dialed in. The lambda readings are hovering between 99 and 100 percent while idling, indicating a precise air-fuel mixture, and the duty cycles are sitting at a healthy 39 percent. Furthermore, the long-term fuel trims are balanced with mostly zeros and some negative twos, which suggests the engine management system is functioning optimally without needing constant corrections. These metrics demonstrate that the tuning process has reached a stable and efficient state.
The testing environment adds a layer of realism to the performance evaluation, as the road surface had recently been repaved, causing rocks to scatter everywhere under the tires. Despite these challenging conditions, the truck maintains its composure and power, proving its robustness in real-world scenarios rather than just on a clean track. The creator repeatedly emphasizes how phenomenal the driving experience has become, contrasting it with the previous struggles where backing up was a "pain in the butt."
In conclusion, the Frostbank tuning project has achieved a milestone where the FIC 2150s is not only running smoothly but also handling specific operational quirks like reversing with ease. The combination of stable fuel trims, correct lambda values, and improved drivability suggests that the engine is fully prepared for more demanding applications. With the mechanical issues resolved and the performance metrics looking solid, the truck appears ready to "bust some rear end" on a proper track, marking a successful transition from a struggling build to a high-performance machine.

Cross bike is running
freaking good.
Hail to the guy.
Oh my
god,
she's ripping.
Ripping.
Oh [ __ ]
Shoot.
Oh man, she's going freaking out.
Oh [ __ ]
Damn, that thing looked good.
Lambo
sitting about 78 Lambo.
She's giving a little bit of a stab
right here.
Driving here, disappear.
Oh my god, it was like a buck 30 and
like less than
Oh my god.
Holy [ __ ]
Calm down Frost bank. Calm down.
We ain't on the track yet, baby.
Oh my god.
I think we got the 2150s
dialed in, baby.
Check the duty cycles like a hot 39%.
Long-term fuel trims
we're sitting at a bunch of zeros
and some negative twos.
We're looking pretty damn good.
Oh, she's spicy, boys.
Ah, they just repaved this road the
other day and uh we're throwing rocks
everywhere.
I am freaking stoked.
The truck is running
freaking
awesome.
And the best thing
that I'm enjoying
is we're backing up.
It used to be such a pain in the butt
for me to back up, dude.
Like if I would back up and then let go
of my reverse button, the truck would
die like every single time.
We don't do it no more.
It actually backs up and it doesn't die.
Like
freaking drives phenomenal.
She is ready for a track set.
Like look at that. All the way up the
driveway, we didn't die one time.
Oh, let's back up again.
That's like the best part of the whole
deal so far is I can actually back up
without the truck wanting to die.
That is bad.
Two to four.
Hell yeah.
Let's go check her out.
She's freaking running, boys and girls.
She is ready to bust some rear end.
Bust some rear end.
Look at that. She's running good, baby.
She's running good. Running good.
>> 99 100 lambda sitting here idling
sipping on that E85
Oh, yeah.
