Truly Mastered & Custom MS41 Calibrations

-Description-
We are proud of what we do here. There are many "tuners" out there that give good ones like us a bad rep. You can be assured that you are getting the best of the best here at Chaos Calibrations, a dyno will prove it. Not only do we target increased drivability and power, but much smoother power delivery as well. Here you can select a range of tuning packages to best suit your needs.

We are the ONLY tuning company in the world also offering tuning via mobile devices with all our in own in house built software and apps!
iOS support is currently planned!

Our Stage 0+ tunes will provide you with a sport oriented options for your vehicle at an affordable price, these don't offer any performance gains though, in that case.
Our Stage 1 tunes are our full performance packages for cars for stock vehicles/minor mods.
Our Stage 2 tunes are our full performance packages for cars with catless headers and/or M50 manifold swaps, etc.

If you are unsure if your MS41 ecu in your E36 3 series/Z Series or E39 5 series is flashable, you can remove it and confirm that the sticker on it has a "INDEX" following a number on the sticker. If does not indicate an INDEX number, your ECU is not flashable/tunable.

-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 Windows laptop and K+DCAN OBD2 Cable. You may also need a BMW 20 pin round connector to OB2 adapter.
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!

Remote Tuning Software Support:
• Windows 10/11 Laptop/PC Software
• Android Mobile App (CCFlash Mobile on Google Play Store)

FEATURES(explained):

• 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.

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.
