A great day today mapping with Clint with and Brock and his superb V4 Sti Type R using the ESL modification to the OEM ECU. Twin fuel, ignition and boost maps were tuned onto the car in addition to running MAFless (speed density) and blistering launch control and anti-lag triggered by a dash switch.

Mods were VF30, FMIC, parallel fuels rails, 680 cc injectors, fuel pump, FPR, Heat range 7  plugs, decat exhaust, factory boost solenoid, ESL ECU and Raijin Performance custom remap.

In 2011 I took owner ship of a standard semi abused V2 WRX. Obsessed with not having anything original, The project began with a E-mail to Andy at ESL to enquire if Self tuning was possible. A ESL Daughter board and a Wideband sensor was ordered. Through countless solutions and help from ESL the tuning began.  With a stock 16G turbo and 460cc injectors it was a fun car. After trying a day tuning with higher boost I managed to blow 3rd gear on the weak early TY752 Gear box.
A slightly stronger later model box was fitted and tuning carried on, This time with a 20G turbo 750cc injectors.
A forged engine was built for the next stage, STI V4 heads and a better fuel system. Suspension was also upgraded to BC coil overs. Tuning was continuously ongoing with trying to fine tune everything I could. (Many more emails and ideas from ESL).
While the engine was roughly where i wanted it the car was looking a little worse for wear. A wide body kit some bigger wheels and a fresh coat of paint changed its look for the better.
Tuning is still continuos with the addition of water methanol injection, ESL has been doing a great job of tuning all the variables that have been thrown at it.
Currently with a ESL Log in Virtual Dyno the car is making 390whp at 1.6 Bar.

Stock Subaru Impreza GT / 22B ECU

There is this wide spread myth, that Subaru manufactured form 1992-1998 can’t be reflashed.This myth, like many others, is not true. OK, honestly, it isn’t easy but it can be done with the ESL Daughterboard!

Chip-Racing Subaru Impreza GT Tuning: ESL Daughterboard

With the help of the daughterboard we’re able to program every single Subaru Impreza ever made. The daughterboard needs to be soldered into the OEM ECU, this isn’t that easy and cant’ be done with shaky hands!

Soldering the ESL Board

Soldering done, ready for the daughterboard

Once the sockets are soldered in, the daughterboard can just be plugged in!

ESL Daughterboard installed

After the installation is complete we can simply program the ECU via ISO or OBD.

The Subaru Impreza 22B which we had here a few days ago was done by the daughterboard as well. Only modification to the hardware is a aftermarket backbox, boost is set at 1.3bar peak and 1bar hold.

A huge well done to the RaceDynamix mapped Fast Japs Talivan en route to 3rd place in the European finals on Gymkhana GRiD. Running on an ESL daughterboard with the new ALS and launch control beta software.

Piloted by Jake Archer and taking on the likes of the mighty Ken Block he came 3rd against very stiff competition beating some of the best in europe along the way.

Well done Jake and Team Fast Japs and good luck for next year :)
