Toyota Supra Mk4 2JZ-GTE

Iconic car for every fan of the tuning industry.This 2jz equipped Toyota supra mk4 is now equipped with an AEM EMS Series 2 Engine Management System tune By us on the dyno.

This is a JDM RHD Version originally producing 280Ps with 2 x ceramic turbochargers. As all 2jz owners know putting out a lot of power from this engine is not too hard but you need to make the right choices.As this model is not equipped with the eu-us  stainless steel turbochargers we decided to keep the boost at low levels until the big single turbo is ready.

After 4 to 5 hours of tuning on our awd Dyno using the road emulation feature we finally got some nice results from this car having perfect mixtures of 14.7 : 1 on idle and cruising adn 11.5 : 1 at wot for keeping the turbochargers cool and healthy at 1.25 bars of boost using the aem plug and play ecu.The car had installed the key elements you need in order to gain more power safely.Aftermarket exhaust system using a racing catalytic converter, an intake system to allow more flow as well as an fmic inter-cooler was previously installed to this car by the owner.

As a request from the client we will not publish the final numbers of the output but the diagram is showing how smooth the car runs retaining most of the horse power until the rev limiter.In this development the limits of the car were the catalytic converter which couldn`t produce any more flow after a certain amount of boost.Car was producing almost the same power at 1.25 and 1.4 bars of boost since the flow of the exhaust gases was not allowed from the catalyst.However the torque gains were great enough to satisfy our client and the filling of the car was totally different after the remapping procedure.

We are always happy to work with such great cars and have great results no matter the personal effort.Enjoy the video of the software development procedure on this Mk4 Supra…
