JC Cosmo Build-Up
January 1999

Modified ECU

One of the main reasons why I went to Japan in January 1999 was to get my factory computer modified to fix a few problems.

When I put the new exhaust system on, the boost level raised automatically and in some cases on a cold night, it started to over-boost and the computer cut the fuel to the engine. This was a real problem and the only real way of fixing it was to get the ECU modified.

I also still had the 200km/h speed limiter activated. The new APEXi guage fixed the 180km/h speed cut but couldn't do the 200.

I arranged to meet with RE-AMIMEYA while in Tokyo. They did an awesome job and modified my ECU to fix all the problems. The modified ECU also has a new fuel and ignition curve as well as a boost controller function that allows me to control boost from 0.9 to 1.1 bar.
