About
Pleiades Performance have a passion for all things Subaru, especially when it involves making more power!
We have been mapping and datalogging Subarus of various specifications in South Wales for 4+ years, for motorsport and fast road use, and are well acquainted with both the EJ20 and EJ25 engines, and know what works well and what the limits are for these engines.
We provide remapping, datalogging, parts sales, and engine builds for most makes and models of Subaru, so feel free to get in touch using the form below or via our social channels (search Pleiades performance on Facebook and Instagram), via email at pleiadesperformance@gmail.com, or by WhatsApp on 07878074666
Remapping
Remapping modifies the data within the car's Electronic Control Unit (ECU), which can enable the engine to develop more power by targeting higher boost levels and using an increased spark advance. Remapping can be undertaken on the road or on a dyno (rolling road).
We can remap standard Subaru ECUS and aftermarket ECUs. Pleiades Performance has most experience with the G4X ECU from Link.
We generally suggest using the standard Subaru ECU for minor alterations to the car (e.g. slightly bigger turbos and injectors), and then going over to an aftermarket ECUs when major modifications have been made (see the picture on the right of our development car, which is now making 470whp using a Link G4X) - Please let us know your requirements!
Datalogging allows the monitoring of various parameters, such as air/fuel ratio, boost pressure, ignition timing, knock count, injector duty cycle, wastegate duty cycle and many more! If you would like to undertake a health check of your Subaru, then datalogging provides a means to show the health of your engine.
