Four fuel types from 91 to 104 octane plus flex fuel are included for each stage. You can update from your phone or computer, or flash a custom map from one of our pro tuners, or even tune yourself.

Functionality

Real flex fuel with a sensor, displays of  ethanol content, full range boost, knock and fuel pressures on the virtual cockpit power and torque gauges, 10 way map switching with custom feature of rolling anti lag using ignition retard, the fastest datalogging of any OEM ECU with huge numbers of useful items you cannot even see on other loggers.

Adjustable launch control, knock display, gauges in the browser. Flashing in 30 seconds to change map, full flashes 3-4 minutes. All wirelessly and safely so that you can even turn off the phone, tablet or computer you started the flash with and it will still complete. 

You can even tune the entire ECU whilst the engine is running and even have your tuner do it remotely. So instead of taking minutes to make a single change you can finally properly fine tune things whilst seeing the results immediately on a fast live graphing datalogger. 

OTS maps/custom tuning

We’ve moved away from canned and closed tunes and our OTS maps are open as examples for tuners new or old to adapt to the platform, or they can merge their existing strategies with ours and enhance their work greatly without needing a standalone ECU.
