-What's the process?-
You are purchasing our remote tuning service. After purchasing your tune, you will receive an email with our software download and instructions to begin the tuning process. It is a very straight forward process. You will need a native Windows laptop and K+DCAN OBD2 Cable.
You'll essentially check for any codes the car may have and save them. Then pull a backup of the ECU as it currently sits and send it in to us. We'll then build your tune, and send it over to you for uploading. It's easy as that!
Go to our FAQ for more details on the tuning process.
Remote Tuning Software Support:
• Windows 10/11 Laptop/PC Software
• Android Mobile App (CCFlash Mobile on Google Play Store)

MSS60 ECU Tuning REQUIRES quality cables with updated firmware. Generic cables from ebay and amazon (and similar) with outdated firmware WILL cause issues when uploading tunes to your ECU. If you are unsure if your cable is right for tuning your MSS60 ECU, feel free to ask us and we can let you know. Our Chaos K+DCAN Cable can be found here: click here

Below is a dyno graph a of stock E90 M3 before and after our tune, on 93 octane. Some companies have stated that it is not possible to gain power below 4/5k rpm, and can only increase power beyond 4/5k, this is simply not true. With proper and efficient changes, we can safely increase power throughout the ENTIRE rev range! Just look at those gains through the power band! Red Line = stock tune. Blue Line = Our Performance Tune.

-Features-

FEATURES(explained):

THROTTLE ENHANCEMENT:

• Enhances the stock pedal feel be a bit more lively and responsive across the board. Not over the top, but just enough.

• Enhancing the servotronic system (electric assist for your steering), making you feel more connected to the road when you need it most.

COLD START OIL REV LIMIT PROTECTION & MAX TEMP PROTECTION :

• We all know how important the right oil and temperatures affect the health of our beloved S65s. From factory, your rev limiter and warmup indicator enable you to rev out your S65 even before your oil temp is fully up to temp. We revised breakpoints and RPM setpoints so you have a more linear and appropriate warmup sequence, only enabling the full rev range when your oil is in the correct temperature window.
  From factory, your ECU only begins limiting your engine speed when your oil temps exceed 150°C, that's over 300°F!!! We have revised this to begin limiting engine speeds right around at the temperature which most oils begin breaking down, so you can catch it and cool down before it's too late. We hope no one ever gets there but, just in case :).

REVISED MAX COOLANT TEMP PROTECTION:

• From factory, the ECU only begins limiting engine speed when your coolant temps exceed 115°C, or 240°F, which may just be too late. Just in case, we have made some adjustments to begin limiting engine speeds a bit sooner.

• Increasing idle rpm can be useful for those that have lightweight flywheels and/or stiffer engine/transmission mounts as it can remove the vibration caused by these modification.

QUIET COLD START:

• This features aims to quiet and almost totally remove the cold start sequence. This may be beneficial to those with catless headers and loud exhausts who want a little bit of a quieter start up in the mornings.

POPS AND BANGS/FLAMES/OVERRUN FUEL CUTOFF:

• This feature enables pops and bangs upon lift off of the throttle. While decelerating, pops and bangs will be omitted from the exhaust. You can select varying ways of enabling this function as well as varying aggressions, some of which can be tailored to a very mild OEM spec setting or, a crazy setting with flames and loud gunshot like bangs. We know it may seem a little complicated on how you would like to have your pops active, so, we'll explain. Check out this Pop and Bang Toggle Styles to read details on the options/styles.

LAUNCH CONTROL FOR 6MT

• 6-speed manual M3s never got launch control, so, we fix that with this feature. This feature sets a standstill rev limiter to your desired choice, as a launch control, to aid you in launching your car from a standstill. You can choose from a variety of RPM setpoints, or a custom one, to try and optimize for your level of grip as best as possible. With this option selected, you'll receive two tunes, one with launch control not active, and another with launch control active.

Datalogging can be conducted to promote the best calibration for your vehicle even without a dyno.
Dyno tuning is available, please contact us if you wish to have your car dyno tuned.

All tunes are allowed up to 3 customer requested revisions up to 14 days after receiving your first tune, at no extra cost.

If requested by the customer, Rear O2 and SAP "Bypasses" are intended to notify the ECU of no longer installed hardware which is already removed by the customer. This is NOT used to pass emissions testing, bypass emission equipment, manipulate emission equipment, etc. It is the customers responsibility to abide by your applicable local, state, and/or federal laws.
