XRT offers professional Subaru Remote Tuning Services with over 16yrs of innovative tuning experience with all types of Subaru’s from different markets – USA to Russia to South Africa; USDM, EDM, SDM, JDM, ADM, Subaru’s such as the 2.0/2.5 Impreza WRX & STI, Legacy, Forester, Crosstek/XV and the Tribeca are all supported.

All Tuning is done remotely out of Barbados. Once you have a laptop/Notebook/Windows Tablet and the Tactrix OpenPort 2.0 Cable, you are ready to Go!

In Remote or E-Tuning, the customer purchase the Tactrix Openport 2.0 Cable and download the rom from the ECU and email it to XRT. During this process, you will log the car using the variables shown here and send me that log or logs with general driving and a few 2nd gear pulls if it is an Auto or 3rd Gear pulls if it is a Manual – all done from low in the rpm (1500+) till the rev limit. An example of a dyno pull is shown below: –


An example of data collected of the stock performance of the car is shown below:-

Once XRT received the rom and the logs, I prepare a tune and email it to you. You will upload this to the ecu and the process of driving and log starts all over again. During this period, you are encourage to give as much feedback as possible and tuning can take a few days to weeks, depending on your time. Usually, a rom per day, your car can be completed in about 3-4 days. Avg time…. 1wk.
