You arrive back at Letty's warehouse just as dusk paints the sky in deep oranges and purples. Inside, the vehicles stand in various states of modification—the Sprinter vans receiving reinforced suspension, the Escalade's engine exposed for its power upgrade, and the sleek Audi RS7 positioned center stage like a technological sculpture awaiting its transformation.
Letty stands hunched over the Audi's open trunk, examining the components you requisitioned. "You weren't kidding about the delivery time," she remarks without looking up. "Show me how these EMP emitters integrate."
You join her at the rear of the RS7, your interface activating automatically to highlight connection points within the vehicle's complex electronics. "The key is isolating the emitter systems from the car's primary functions. We don't want our countermeasures disabling our own vehicle during deployment."
With surgical precision, you guide Letty through the installation. Your hands move with unnatural certainty as you route cabling through existing conduit paths, splice into power sources without compromising vital systems, and program the deployment sequence through a tablet connected to the car's brain.
"These frequency modulators shouldn't work
Electronic Warfare: Perfecting The Countermeasures
Night falls over Los Angeles as you return to the warehouse, finding it transformed into a hive of focused activity. The Audi RS7 sits at the center, hood and panels removed, exposing its electronic nervous system. Letty kneels beside it, hands steady as she integrates complex circuitry beneath the dashboard.
"I was just about to call you," she says without looking up. "The jammers arrived, but the integration points aren't matching the schematics."
Your interface activates automatically as you approach, scanning the vehicle's systems and the components spread across the workbench:
[SIGNAL JAMMERS: MILITARY GRADE, MODIFIED CIVILIAN USE]
[COMPATIBILITY ISSUE: DETECTED]
[AUDI ELECTRONICS: LATEST GENERATION FIREWALL PROTECTION]
[SOLUTION PATHWAYS: CALCULATING]
"The Audi's security system is fighting the installation," you observe, kneeling beside Letty. "It's detecting the jammers as unauthorized hardware."
"Exactly." She wipes sweat from her forehead with the back of her hand, leaving a smudge of grease. "I could brute-force it, but that would trigger fault codes, reduced performance. We need these vehicles at one hundred percent."
Your interface provides the solution before you consciously formulate it:
[ADAPTIVE SPOOFING PROTOCOL: RECOMMENDED]
[APPLICATION: VEHICLE ECU MASKING]
[PROCESS: HARDWARE IDENTIFICATION REPROGRAMMING]
"We need to make the car think the jammers are factory equipment," you explain, reaching for the diagnostic tablet connected to the Audi's computer. "I can rewrite the vehicle's hardware recognition protocols."
Letty watches as your fingers fly across the screen, coding sequences that shouldn't be possible without specialized factory tools. The tablet's display flickers as you penetrate security layers designed to prevent exactly this type of modification.
"That's not standard hacking," Letty observes, professional appreciation in her voice.
"No," you acknowledge, continuing to work. "But it's necessary."
The interface guides your inputs, allowing you to see pathways through the vehicle's digital architecture invisible to normal technicians. Within minutes, the Audi's security system accepts the jammers as authorized components, green status lights confirming successful integration.
"Now for the real challenge," you say, moving to the rear compartment. "The EMP emitters need precise calibration. Too weak, they won't disable pursuit vehicles. Too strong, they could affect civilian infrastructure."
Letty brings over a specialized oscilloscope, positioning it beside the open trunk. "How do we test something like this without actually deploying it?"
Your interface accesses simulation capabilities:
[ELECTROMAGNETIC SIMULATION: INITIATING]
[PARAMETER: CONFINED FIELD TESTING]
[TARGET: PURSUIT VEHICLE ELECTRONICS ONLY]
[CIVILIAN INFRASTRUCTURE: PROTECTION PROTOCOLS]
"We create a contained testing environment," you explain, retrieving additional equipment from the supplies you requisitioned. "This field generator will simulate federal vehicle electronic signatures within a three-foot radius."
Together, you construct a testing apparatus that allows precise calibration of the EMP emitters. Each adjustment requires mathematical precision beyond normal human calculation, but your interface processes the variables instantly, guiding your hands to microscopic adjustments.
"These calculations," Letty says after watching you work for twenty minutes. "They're not something anyone could do. Not even Jesse with his savant abilities."
You pause, meeting her eyes. "Does that concern you?"
She considers the question seriously. "No. But it does make me curious about what else you can do."
Rather than answering directly, you complete the final calibration. "Test it," you suggest.
Letty places a standard police radio and a civilian smartphone within the testing field, then steps back. With a nod from you, she activates the emitter at minimum power.
The police radio immediately goes dead—screen blank, communications severed. The civilian phone continues functioning perfectly.
"Selective targeting," she whispers, genuine awe in her voice. "That's..."
"Exactly what we need," you finish. "Federal pursuit vehicles will lose communications, GPS, engine management systems—everything electronic—for approximately twenty seconds per burst. Enough time to create distance or change direction without being tracked."
Letty's expression shifts from professional appreciation to something more personal. "You know, in all my years working with Dom, I've never seen anything like what you can do." She gestures to the perfectly calibrated system. "This kind of edge—it changes everything."
"That's the point," you acknowledge. "The old methods aren't enough anymore. Federal response has evolved. We need to evolve faster."
You move to the Sprinter vans next, implementing similar but distinct countermeasure systems. The interface guides you through each installation, ensuring perfect integration while Letty handles the mechanical aspects—reinforcing mounting points, creating concealed deployment mechanisms, establishing driver controls.
Hours pass in focused collaboration, the warehouse silent except for the sounds of tools against metal and the occasional exchange of technical information. Your interface notes the passing time:
[CURRENT TIME: 02:34 AM]
[WORK COMPLETION: 76%]
[ESTIMATED COMPLETION: 3.2 HOURS]
"We should take a break," you suggest, noticing the fatigue in Letty's movements despite her determined focus.
She stretches, rolling her shoulders. "I'm good. I can push through."
"Precision drops approximately twelve percent after eighteen consecutive hours of technical work," you state. "We need these systems perfect."
The factual approach works—Letty nods reluctantly and moves to a small refrigerator in the corner, retrieving two beers. She offers one to you, then drops into a folding chair near the Escalade.
"You care about this crew," she observes after a moment of silence. "It's not just about the score for you."
Your interface analyzes response options, but you set aside its recommendations, allowing something more authentic to emerge. "Where I'm from, this crew—Dom, you, all of you—represented something important. Family built by choice, not blood. Loyalty without limits."
"And now you're part of it," Letty says, studying your reaction.
"Working on it," you correct her. "Trust is earned, not given."
She nods, taking another drink. "True. But you're earning it faster than anyone I've seen." A thoughtful pause. "Even Brian took longer, and he saved Dom's ass at Race Wars."
The comparative assessment registers as significant. Your interface flags the development:
[CREW INTEGRATION: ACCELERATING]
[LETTY ORTIZ: TRUST LEVEL - HIGH]
[PERSONAL CONNECTION: ESTABLISHED]
The brief respite ends as Letty stands decisively. "Let's finish these systems. Dawn's coming soon, and we need to be ghosts before the industrial district wakes up."
The final hours of work pass in a blur of focused activity. You integrate the helicopter countermeasures into the Escalade's roof panels—sophisticated frequency jammers that will temporarily disorient aerial tracking systems without endangering flight capabilities. The technology exceeds military specifications, made possible only through your interface's ability to optimize beyond normal parameters.
As dawn's first light filters through the warehouse windows, all four vehicles stand complete—lethal in their capability yet visually subdued. Nothing about their external appearance suggests the technological arsenal hidden within.
Letty circles them one final time, professional assessment in her eyes. "They're perfect," she concludes. "Better than anything we've ever run before."
Your interface confirms her assessment:
[VEHICLE MODIFICATIONS: COMPLETED TO SPECIFICATIONS]
[COUNTERMEASURE SYSTEMS: FULLY OPERATIONAL]
[PURSUIT EVASION PROBABILITY: 94.7%]
[MISSION READINESS: VEHICLES CONFIRMED]
"Dom needs to see this," you decide. "The whole crew does. It solidifies the reality of what we're planning."
Letty nods in agreement, already reaching for her phone. "I'll tell him to gather everyone at the garage. Noon."
As she makes the call, you conduct one final systems check on each vehicle, your interface mapping every connection, every circuit pathway, every potential point of failure. The precision engineering approaches perfection—a testament to Letty's mechanical genius combined with your technological capabilities.
"Dom's calling everyone in," Letty confirms, ending her call. "Says to bring the Audi and the Escalade. The vans stay hidden until the day of."
The strategic decision makes sense—showcasing the technical achievement while maintaining operational security for the primary transport vehicles. As you prepare to move the vehicles, Letty pauses, hand resting on the Audi's hood.
"Whatever happens with this job," she says quietly, "you've already changed how we operate. Raised the bar." Her eyes meet yours with uncharacteristic openness. "That doesn't go unnoticed."
The acknowledgment carries weight beyond professional respect—it represents acceptance into the core of Dom's family, the inner circle where trust is absolute and loyalty transcends the job itself.
"Let's show them what we've built," you respond, the dawn light reflecting off the vehicles you've transformed from mere transportation into precision instruments of an impossible heist.
