We are excited to announce new features coming soon for the B-Spec Tune.
As always, updates and new feature requests are free to existing B-Spec Tune owners.
- MK20 Performance Traction Control (2001-2002 only): For those with the older MK20 units, we are testing out a performance calibration tune for the MK20 DSC unit. You may notice that the MK20 DSC kicks in a lot harder and more frequent than the later MK60 (2003-2006). The later MK60 has the option of M-Track Mode, however MK20 unit does not have this feature. This feature should help with Launch Control with MK20 Performance Traction Control and making the MK20 less sensitive with aggressive wheel/suspension setups for track days while still keeping DSC on.
- Ignition Tuning: We are testing out ignition based rev limiter cutoff to aid with no lift shifting. Stock is a 2 stage rev limiter cutoff with fuel and ignition based. Prevents the harsh fuel cutoff at redline.
- Full Idle Remap (catless Only): We are testing out a cold start remap program that in conjunction with the SAP program disable should make your neighbors a lot happier with those that are running catless. Idle rpm will now be based off of engine temperature sensor instead of catalytic converter sensor temperatures. In essence, idle will try to protect the motor instead of protecting the catalytic converters. We are also researching cold start remap scaling to solve the issue of the standard idle scaling being still too noisy.
- Lower and Raise Idle: We are testing out the capabilities to raise idle that could help with those who have solid motor mounts and experience NVH.
- Higher Redline Rev Limiter: We can now raise the rev limiter to 8,200 RPM while maintaining a flat power-band at that rpm. This will be considered aggressive.
- Flex Fuel Kit: We are testing out the compatibility of E85 flex fuel kits being used with our B-Spec Tune.
Released:
- Launch Control RPM Limiter (6MT only)
- Ability to raised standing Idle RPM for NVH or E85 (6MT+SMG)
- Raised Redline to 8,200 RPM
In Beta Testing:
- E85 Flex Fuel Kit compatibility with tune (Dyno Scheduled 3/17/18)
- Flat Foot Shifting (6MT+SMG)
- Ignition Based Cutoff (Allows for Flat Foot Shifting)
- Ignition/ 2 Stage Fuel Cutoff (Default)
- B-Spec Tune Performance Traction Control for MK20 Only – (2001-2002.5)
- DSC Applied Torque Reduction
- Revised Initial Torque Intervention Value
MK20 DSC Unit E46 M3
In Research & Development:
- Idle Remap (Cold Start Remap)
- Quieter Idle Scaling (based off Temperature).
Are you concerned about running into issues using the Walbro 255 fuel pump in combination with E85?
I’m running AEM 50-1200 fuel pump for E85 to be safe on track days. Andrew is running Walbro 255 on 91 octane. But stock fuel pump works as well, I ran it for a couple weeks. It does wear it out a bit faster, I would just run it with stock fuel pump until it gives out and then switch to an E85 compatible pump. https://thebuildjournal.com/wp-admin/#comments-form
very interested in a re-tune when its ready for the ff:

and E85 tune.
Hello-
I have an 03 with SMG. I recently saw the Twinline Garage review of the B-Spec Tune for M3. I’m wondering if you have a recommendation for intake and cat-back exhaust system? I’d like to go with the components you’ve found work best with your tune.
Thank you.
Travis
Hi. I recommend Eventuri CF intake, GruppeM or Dinan. For the cat back exhaust, you’re not going to find huge difference in gains. Not until you go catless. So I would say pick any catback exhaust that you like, sound-wise.
hello how about higher power and torque curves in the lower rpm range like you mentioned last year.
Hi Alex. We continually try to improve our tune by optimizing engine parameters for performance and reliability. New versions are released periodically. Is there a specific output you have in mind?
Will the E85 be beneficial in power wise? Interested in 8200 rpm but is it safe?
E85 will benefit with extra horsepower. Cool thing (literally) is that E85 doesn’t burn as hot so it cools the car down better. 8,200 RPM is set so users can hit 8,100 without hitting fuel cutoff. It’s not intended to actually reach 8,200.
