MultiMap Composer

The MultiMap composer tool adds mapswitching to various control units. The composer is a collaboration between VehiCAL and Tangent Motorsport.

Features:

Automatic multimap file creation by the composer. Simply upload different versions of the same file. No need to add custom maps or locations - work as normal in WinOLS.
Once you have paid for a VIN you can re-create the Multimap file as many times as you like free of charge, just upload your modified files again.
Human-machine interface via cruise control. The selected map is stored in EEPROM and remembered upon restart.
Quickslot support in the Advanced variant allows you instantly switch the map while holding the cruise control in "reduce speed" position and switch back upon release. Great for e.g. pops/flames/antilag on demand.
ECU bricking protection - by default code is not executed until the engine starts turning over. If there is an issue with the file or switched maps the ECU can be reflashed.

Requirements:

Full files must be uploaded, that have both the calibration and code.
You must be able to checksum the MultiMap file.
You must be able to write the full file to your ECU, not only the maps area.
No refunds will be given if you fail to observe these requirements!

The contract is considered concluded after the switched file is delivered to you. Checksumming and writing it to the ECU is your responsibility, not ours.
Do not contact us for flash tool support - this is handled by your flash tool provider.

Pricing (15-35 credits) (click to expand)

Basic - up to 8 slots, 15 credits.
Advanced - up to 8 slots plus Quickslot, 25 credits.

High end brands have a +10 credit surcharge, enter your VIN to see the exact price.

Limitations (click to expand)

Do not try to "switch the world". E.g. diagnostic code areas can not be switched. Make a base file, and then change what you need from it, rather than uploading completely different tunes or a fully stock file.
Function monitoring can not be switched. The tool will detect it and give an error, as that would result in a reset loop.
Logic that is only read one time at ECU startup can not be switched. This includes single value VMAX on some software variants.

Steps:

Enter your VIN.
Select Basic or Advanced mode.
Upload your files (up to 8 slots). In Advanced mode you can also add a Quickslot file.
Click Verify to check compatibility.
If verification passes, click Create to purchase a license and generate the multi-map file.

FAQ (click to expand)

Q: How to switch maps?

Option A - Press and hold cruise down, then press up/down to switch maps
Option B - Press and hold brake, then press and release accelerator pedal to switch maps while holding the brake.
Press and hold cruise cancel to switch to Quickslot map.

Q: How to activate the Quickslot?

A: Press and hold cruise cancel, the Quickslot is active as long as it is held down.

Q: The maps do not switch without the engine running!

A: This is by design for safety reasons to avoid the possibility of bricking the ECU. The switching logic engages the moment the engine turns over. If you would like to override this, look at mapsw_config_addresses.txt inside the .zip file you have received, and set the reset_prevention_switch from 1 to 0. Once done mapswitching will work with the engine off. Keep in mind that if you directly flash a such file before testing it then you can brick the ECU.

Q: Can I upload fewer than the maximum amount of files?

A: Yes, the minimum is two files, just leave the rest of the slots empty.

Q: Who can see my files?

A: Nobody. The individual files and the result are immediately automatically deleted after the request is handled. We can only see your files if you specifically open a support ticket and send them to us.

Q: I don't want to send my tuned files with you, can I still use the service?

A: Yes, instead of uploading maps with real tuned values, place a marker in the maps you want to switch.
For example in file 1, map 1, place 1111 in the map or fill the map with 1101, then in file 1, map 2 put a different marker, like 1102, and so on. For file 2 you can do 2201 and 2202 respectively, or whatever you like. This marks the map for the tool as needing to be switched.
You can place any kind of marker, just make sure every marker is unique.
Once you build the multimap file, open it and search for your markers in WinOLS to identify the locations of the switched maps, then edit the maps directly in the switched file.
We do not provide a mappack for this, you will have to find the markers yourself in the switched file.
