Paul Johnson S58 - BMW F97 F98 X3M X4M CUSTOM TUNE

Custom tuning for S58 is available for pump gas, race gas, full E85 and E85 blends. Results will vary depending on the fuel used and the weigh/traction of your particular S58 model.

While full E85 tuning is possible on the S58’s stock fuel system, we have found that an E50 blend produces the best overall results because it allows for more boost while still retaining good ignition timing.

Some of the available map features  :

• Top speed limiter removal
• Exhaust flap adjustments
• Cold start (cat heating on startup) removal for quieter cold start
• Cat efficiency check (CEL) removal for de-cat downpipes (for off-road use)
• Maps for upgraded turbos
• E85, Ethanol blends, race gas and meth injection tuning
• Custom Pedal Mapping
• Linear torque curve maps
• Traction management by rpm/gear
• Road course, 1/4mi Drag, and 1/2mi specific tuning. 
• Backend Flash maps for use with piggybacks
• Custom burbles with greater aggression/adjustment range than OTS maps.  
• Gunshots/flames tuning (requires full decat)
• Customized i-Drive sport gauges

Our custom tunes require the remote tuning platform Bootmod3 by Pro Tuning Freaks.   BM3 licenses can be purchased here on our website. 

Once you have purchased a custom tune from us and have activated your BM3 license you will need to request a custom tune within the BM3 app.  Here's how:

Within the Bootmod3 app you would go to your "My Maps" screen and click the button at the top "Request Custom", then choose  "Paul Johnson Tunes".   In the description/comments list your mods, fuel(tested eth% etc), and goals for the tune.

Additional custom map variations for the same vehicle after initial tune (such as a matching pump gas map to accompany a race tune) can be purchased for $450

Once we receive your payment and your BM3 tune request Paul will prepare the base map for you to flash. 

Once the base map is flashed to the vehicle you will datalog the car.  Paul will review the logs and make the necessary revisions to the tune based on the logs.
