What is Etuning and does it work?

Etune or Etuning: to create a custom ECU/EMS calibration/map for an engine/car through the internet (from a remote location). This process usually requires data logs to be sent through email to the tuner who will review the data and email an updated calibration/map back to the customer/car.

Etuning has opened up opportunities for people in remote places without any local “tuner” to build the car of their dreams and have it professionally tuned for $500-800 USD. Over the past 15 years Etuning has become increasingly popular with our customers both international and domestic. Brewed Motorsports offers Etune support for just about every ECU or EMS on the market including: Motec, AEM, Haltech, Vipec, Hondata, Cobb and many more. Now more than ever we are tuning cars for customers looking to get more performance than their local shop or tuner is able to provide. If you want the absolute most out of your build we are here to make that happen.

Here is a good example from one of our Brewedtuned RB26 customers that hit the dyno to compare the real world roller dyno reading with our Virtual Dyno results from Etuning. The results from Virtual Dyno and the roller dyno used were extremely consistent and the car has been making over 600 hp at the crank with only 19-20psi for the past 7+ years. Not only does this car see regular street time in Europe it also crushes super cars at the local circuit on the weekends! ***this is a stock block N1 RB26 with OEM nissan pistons/rods/bearings and crank.***
