Powered by ESL, Tuned by FC Tuning. This lovely Subaru Classic, now Tuned on the factory ECU utilising the wonderful ESL daughterboard which enabled the ecu to have switchable maps and also run mafless for added reliability. Another classic given a boost and ready for some fast road action.

A stunning mint Subaru Impreza STi Prodrive in for a custom FMIC conversion and mild tune on the OEM ECU.

Plans for the future include be a 500hp build.

Great torque low down from the EJ25 engine and a good base platform now to work from as this owner looks to perform more engine upgrades in the future.

In for tuning this STI with its modified VF series turbo. Little was known as to what power n torque to expect. So it was a case of initial check, strap down and tune. She did well. Enough power for the London Streets

EJ20 is stock in this case

In for some TLC before FC Tuning, we had this wonderful example of a UK Spec STi. An owner new to the Subaru platform The customer was advised to upgrade the tired old pump before any tuning was to commence. I couldn’t have agreed more. So out with the 10 year old stock pump and in went a nice fresh upgraded in-tank fuel pump in its place. Once the all important Dyno Prechecks had been done and enhancing ignition with a fresh set of plugs it was time to get setup on the dyno. A new actuator is on the way and this STI should net even more horsepower top end. Still. The owner has a nice baseline to work from. A fantastic Subaru Impreza making nice hp and tq.

This beloved Subaru Owner had been previously led around the garden path by another engine tuner that attempted to set the engine and ecu up on the road without much success causing serious piston damage.
The car and its owner then looked to Redline Motorsport to perform the surgery. So a full engine strip down, assessment and rebuild within a couple of weeks sharp including all mating meant the owner wasn’t off the road for too long.
The car was then put back to factory form and then setup professionally using the dyno and checked on the road.
The aim wasn’t massive power with this tune but to give the owner the pleasure of driving his beloved Subaru Impreza which the previous company had failed to allow him to do
Still with all the Catalytic Converters fitted power and torque was expected.
In the future Redline Motorsport expect to see the car back Redline Motorsports 350hp upgrade package

TUNING THE SUBARU EJ20 WRX

fctuning — Sun, 24 Aug 2014 15:37:03 +0000

This beautiful Subaru Impreza WRX show car came to us from Kream Developments. It was presented in show condition and needed careful ECU tuning to match.

We worked with the OEM factory ECU to carry out the Subaru EJ20 WRX Tuning. The goal was smooth, reliable power while keeping the factory drivability intact.

The Subaru EJ20 engine is known for its boxer layout and strong low-end torque. In WRX form, it uses a turbocharger to produce impressive power from a relatively small displacement.

A show car needs to perform as well as it looks. We made sure the tune delivered strong power and a smooth power curve throughout the rev range. Another great result for a Subaru Impreza WRX.

TUNING THE SUBARU EJ20 (P1)

fctuning — Wed, 13 Nov 2013 01:36:15 +0000

This Subaru EJ20 P1 Haltech Tuning session was a UK first. We replaced the old OEM ECU with a brand new Haltech ECU — a first for a P1 in the UK.

There is a big story behind this P1. The new owner took on a project car that was in very poor condition. It needed serious work before it could be tuned.

Redline Motorsport rebuilt and prepped the engine. The entire chassis needed a full strip-down. They removed the old loom in favour of fresh wiring to suit the rebuilt engine and the new ECU.

The Subaru EJ20 engine was rebuilt from fresh OEM components. With the clean build in place, the Haltech ECU was the obvious choice. It offered the best flexibility and performance for this level of build. The result was a well-sorted, reliable P1 with strong power and excellent drivability.

TUNING THE SUBARU EJ20 (WRX)

This Subaru Impreza WRX EJ20 Tuning session was carried out on Redline Motorsport’s own Subaru Impreza WRX. The car was built to the RM_S1 package specification.

Redline Motorsport is a well-known preparation and performance outfit. The RM_S1 package is a carefully developed setup designed to get the most from the Subaru EJ20 engine in road and track use.

We carried out custom ECU mapping to suit the full specification of the build. The tune was tailored to the exact modifications fitted, ensuring the best possible power output and reliability.

The result was a well-sorted Subaru WRX with strong, linear power delivery. A great package from Redline Motorsport, backed by a professional custom tune from FC Tuning.

This fast road Subaru Impreza WRX came in for bolt-on modifications and OEM ECU tuning. It is a daily driver used on London streets and needed a reliable, smooth power increase.

The Subaru EJ20 WRX always responds well to a few key upgrades. We fitted the VF34 turbo from the later STI models. This was paired with an exhaust upgrade and a front-mount intercooler. These modifications are essential for high-boost longevity on track and to push past the factory 220hp figure.

The custom OEM ECU tune completed the package. Power delivery became smooth and predictable, perfect for a fast road car used every day. A nice, swift result for a London daily runner.

This is a UK first — a custom ECU and fresh loom fitment specifically for the Version 5 Subaru EJ20 Impreza P1. The project is a collaboration between Redline Motorsport and FC Tuning.

The Haltech Sprint 500 ECU was chosen for this build. It offers the flexibility and precision required for a fully rebuilt P1 at this level. The custom loom was designed and fitted to suit the specific requirements of the EJ20 engine and the Sprint 500’s wiring.

This video captures the first start with the new ECU and loom installed. The EJ20 fires up cleanly and sounds great. Before full dyno tuning and boost control can be set up, the engine needs some break-in mileage first. An independent boost controller will also be fitted prior to the full dyno session.

Stay tuned for the full dyno action in the coming weeks. This Subaru P1 project is shaping up to be one of the best builds we have worked on.
