GReddy's E-Manage is once again the weapon of choice.

When GReddy's E-Manage was first introduced to the Malaysian market, there were horror stories and unfounded rumors going around that the E-Manage was absolute crap. Some even went as far as calling it the E-Damage. These were the words of ignorant fools and misinformed ignoramuses, as the E-Manage is truly a very capable piggyback ECU. There were reports and stories of an Evo 7 blowing itself up on the dyno because of the E-Manage, but this was most probably due to an inexperienced tuner or an unhealthy engine.

Today, the E-Manage's capabilities as a piggyback ECU have been proven over and over again, with many tuners praising its ease of use and features.

The Proton Wira you see here started life as a run-of-the-mill 1.5, with the lethargic 4G15 powering it. The Wira now has a 4G93 GSR engine, with oversized pistons and a TD05 turbo, as well as upgraded injectors and an upgraded fuel pressure regulator. Built by Skyzone, this car now had all the hardware, and needed the proper software to get it running properly.

Skyzone, a workshop situated in SunwayMas, near the Hypertune office, is well versed with turbo Mitsubishi engines and was responsible for the Evo 7 cover car featured in Volume 68 with Hannah Tan.

Originally, the car was supposed to get a Microtech LT-4 to fine tune the fueling, but as we soon found out, the unit was faulty. One of the inputs on the LT-4 was not working, so we couldn't get the Microtech to detect anything.

This is where the E-Manage came into the picture. Brand new and out of the box, Avantgarde installed it and we were ready to get started on making horsepower.

The car was strapped on to the dyno and we started making a few runs to get the baseline power figure. But we noticed that the car was losing power right where it should be making the most power and it was sputtering. It turns out that one of the spark plugs was mismatched. After swapping in a new set of plugs, the car ran much more smoothly and we were ready to get down to business.

On its first run, the car pulled a decent 199bhp at the wheels. We were quite happy with this figure, but the car was running extremely rich with an a/fuel ratio of 10.12, so we knew we could make more power by tweaking the air/fuel ratio a little.

James of Avantgarde went to work, and the final result was a much more satisfactory 217.66bhp at the wheels. The air/fuel ratio was now a slightly leaner 11.76. Because of the leaner fuel mixture, the exhaust gas temperature increases and boost pressure was increased slightly, from 11psi to 11.53psi, or approximately 0.7 to 0.8 bar.

Satisfied with the increase of 18.66bhp at the wheels, the owner of the car went home boosting happily.

This month's Power Pages segment again emphasizes how important it is for your car to have a good tune, especially if it's turbocharged. Always remember never to skimp on engine management and always get the best that you can afford, because a good tune could mean the difference between making safe and reliable power, or sending a piston flying across three states.
