Tuning without an ecu swap or unlocking of the ecu is here!

68RFE trucks can receive 0hp file flashed via EZ Lynk, EFI Live, HP Tuners and Spartan Series Flash Tool 

68RFE trucks can get a 100HP file via Spartan series flash tool only. 

Aisin trucks can can get 0HP or 100HP files via Spartan Series Flash Tool only.

EZ Lynk requires permanent or temporary lynk option to be chosen.  Android/iOS smart phone is required

HP Tuners files requires 6 credits - Requires Windows Laptop PC

EFI Live Autocal V3 comes with 1 vin license right out of the box. Requires Windows Laptop PC. 

Spartan Series Flash tool requires no credits.    It does require a Windows Laptop PC. 

Security bypass cable is required for OBD port tuning.

*Spartan Series Flash Tool rental requires a Refundable deposit of $1000 which is sent as a sepearte payment link, shipping costs of the tool rental program are at the customers expense*

The Spartan series OBD flash tool allows for limited calibration file flashing of the ECU via the OBD port.  You can get a 0hp or 100hp file WITHOUT swapping the ecu or sending the ecu out to be unlocked.  All you need is a windows laptop with wifi connection and our techs will remote in and complete the flash for you. No risk of user error!

The spartan series tuning is designed for stock turbo, stock fuel system and stock intake trucks with off road race exhaust/egr upgrade kit.  In you plan on ANY modifications over and above EGR and DPF removal, then locked ecu tuning is not the choice to make.  We recommend ECU unlock service and HP Tuners for those vehicles. 

We have found that there are two map sensors that FCA utilized during production of the 22+ Ram 2500/3500 during covid.  One was produced by Bosch, the other was produced by Cummins.  The Bosch map sensor can struggle with voltage transfer when more boost than stock psi is commanded at lower rpm ranges. To resolve this potential risk that will be unknown until tuning is installer, a cummins map sensor may be required ($500 USD value) just in case the issue becomes present.

Calibrations

• 22+ Locked Ecu 0hp - best for those who work their rigs! This is a great heavy towing option. 
• 22+ Locked Ecu 100hp - good for those that do light towing but mostly daily drive *upgraded map sensor required*

Engine Calibration

• Increased throttle response (reduced or elimination of dead pedal)
• Increased torque in all power levels which allows earlier shifts when applicable for improved fuel economy 
• Increased fuel economy due to optimal commanded fuel quantity, injection events, timing, and trans calibration
• Quicker response to driver input due to transient fuel, timing, VGT and Transmission calibration
• All safe non aggressive OEM detune / back down strategies are left intact or calibrated for the higher power levels that prevent premature failures
• All limiters that are safe to be removed are
• Exhaust brake memory and maximized exhaust brake 
• Removal of auto start and stop as well as idle timers 
• Tire sized changed and if opted for transmission calibration it is optimized for specific tire size / gear ratios

Transmission Calibration - 68RFE or Aisin

• Extended transmission life, increased fuel economy, and better driving experience 
• Increased line pressure and shift parameters that would reduce shift times, slip etc follow actual torque models in ECM and TCM
• This strategy increases fuel milage, reduces duty cycle wear, eliminates harsh or random inconsistent shifts or characteristics that do not match the drivers request, input or desired feel
• This is why it is important the engine calibration be done correct or our transmission calibrations be paired with our engine calibrations as the models have to mimic each other
• All calibrations match the increased torque as well as earlier torque to apply it most efficiently
• Refined shift points to get rid of the low rpm lazy feel at low driver inputs cruising or towing waiting on the turbo to spool that usually results in a lot of pedal travel and down shift
• Tire size, gearing, and larger turbos this is a must to tailor to that specific mod
• Earlier converter lock up to use increased torque & increase fuel milage as well as reduce temps
• Earlier unlock & downshift eliminates lag from time of driver input to acceleration
• Torque converter OEM partial lock or locked shifts to remove flare feel during shifts
• TC feel can be stock or increased for less slip to lock time in 2-6 gears
• Full manual control over shifts in driver select mode
• Stock tuning 160 PSI 
• Stock valve body 170 PSI 
• Aftermarket valve body 225+ PSI recommend for calibrations above heavy tow
• Since hydraulic pressure is directly related to your clutch holding power we do not recommend tuning over heavy tow without a aftermarket valve body

Transmission Calibration

Our Transmission tuning is unrivaled, with extensive research and development that stems from a deep understanding of both the mechanical parts and TCM logic. Our transmission tuning for Ram Trucks (2003-Present) is based on real-world experience, having built over 1600HP transmissions in-house and applying that knowledge to our specialty tuning. Our calibrators aren't just theorists—they build transmissions.

Why Choose EOC for Your Transmission?

• Tuning for Tire Size and Gear Ratio: Say goodbye to struggling with oversized tires. We tailor our transmission tuning to match your specific tire size and gear ratio, ensuring smooth, controlled performance.

• OEM-like Feel or Firm Shifts: You can keep the torque converter (TC) behavior close to stock or upgrade to firmer shifts with early lockup. We offer options to lock the TC in 2nd, 3rd, or 4th gear, with our most popular option being the 3rd Gear TC Stock Feel.

If you're looking to maximize your 68RFE or Aisin’s power delivery and keep it reliable, we've got you covered with locked shifts.
