Not all tuners adjust the ECU calibrations the same, that likely doesn’t surprise you. However what might surprise you is how it’s actually done. Here at ARD we tune each ECU by hand according to the customers environment, vehicle mods and particular driving style. Each file is read out from the ECU then decoded and put into our editor. We then edit the necessary maps, save the file, and load it back to the ECU. By tuning ECU’s this way we can make sure that all the relevant maps and values are edited for optimal performance and efficiency.
