The DAZA (and now DNWA too!) DS1 product comes after the roaring success of their 4.0T product. They have incorporated all the same features, however they do not have OTS maps beyond stage 2.  VLMspec offers custom mapping for this product and any combination of hardware.


VLMspec Custom Tuning support available here 

Flex Fuel/ ECA Kit available in combo or separately here.


They have things like 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 or hours to make a single change you can finally properly fine tune things whilst seeing the results immediately on a fast live graphing datalogger. As a company, they have moved away from canned and closed tunes. Customers or tuners new or old can adapt to the platform, or they can merge their existing strategies with Dyno Spectrum's or VLMspec's and enhance their work greatly without needing a standalone ECU.
