New design* is universal** for any ECU from 24-pin Motronic 1.0 (E24/E28/E30, early Porsche 944), to 28-pin Motronic 3.x (E34/E36/E38). Including BMW E30, E36, Honda Civic, CR-X, VW Golf, VR6, Porsch 944, Carrera… and more!
The SSSwitchBoard is a great piece of hardware for those of you looking to run two separate tunes in your Motronic 1.0 to 3.x ECUs, Honda, Nissan, and Toyota ECUs for situations like track days, smog testing, valet/shop security, fuel economy, octane switching, etc! What it does is allows you to install two chips within one single ECU and choose between which one you want to run. The best part? The SSSwitchBoard does not discriminate between tunes or brands! Use any chip from any company you wish.
Install a performance tune in one slot for track days with higher octane, and the stock chip in the other slot for lower octane and daily driving; or get a valet mode tune in one slot to limit RPM and speed, and your race car tune in the other, because race car. Quickly switch to a stock tune when putting your car through smog testing and never have to worry about anything looking out of place, then switch easily back to your performance tune as soon as you leave the shop with a crisp new “PASSED” sticker on your windshield. Never have to worry about a gas station having the correct octane on a road trip by easily switching back and forth between tunes with the flick of a button. Heading to the dyno and need to compare two different setups? Not a problem!
Hot-switching (Hot-swapping) is possible when running two compatible SSSquid tunes, or two tunes of the same base!****
Simply run the cable from your ECU to any mounting position of your choice, and hide the switch easily in your cabin with the included incognito black waterproof molded cover. Some ECUs require an optional offset adapter board, to clear the case or other components. Check the spreadsheet below to see if your ECU requires an adapter board.
- 36in cable + switch
- (optional) Adapter Board (please consult spreadsheet below)
By default the unit works in 28-pin mode. In order to select 24 pin operation, simply connect the top-side jumper! To select 28-pin mode, simply disconnect the jumper. It’s that easy!
*previously known as “SSSquidBoard”
**universal in operation, and should fit the form factor of most ECUs fine. Please check dimensions if unsure.
***to use one 24-pin and one 28-pin chip in the same board, leave the 24-pin jumper DISCONNECTED.
****while you can technically hot-switch any two tunes, doing so with tunes that do not share the same basic software and calibration may negatively affect your vehicle’s operation.
