Cost  
$1800 fully installed with dyno plots pre and post installation. This also includes a water spray kit.  

Background 
Although the Microtech is made by a Sydney based company of the same name, BGT market it in Melbourne under their own name (the BGT ECU). Vin was adamant to point this out, but for the purposes of ease and to avoid confusion, I shall continue to refer to it here as the Microtech. 

The ECU is a full replacement unit for the WRX. BGT also offer a piggyback model to allow fitting to other cars (the MT8 version of the Microtech). The piggyback unit can be fitted to the MY99 if the customer really wants one.  

Vin has been in the industry for over 13 years and has worked with Motec, Autronics, Wolf and Haltec systems in that time. BGT own a highly modified WRX wagon, which Vin races and uses for development work. 

BGT tune all cars on their own in-house 4WD dyno. 

Features 
The Microtech offers a host of functionality, most of which are best summarised on the BGT web site. There are 16 load and 16rpm sites giving a total of 256 mappable points. The rpm sites are spaced at 500rpm intervals from 500 through 8000rpm and are not changeable. There are 16 boost levels spread over the same rpm increments.  

The Microtech offers data logging for the serious punter and BGT will sell you their tuning handset ($165) to allow this. The "enter" key is disabled to stop users altering the tune however.  

The ECU comes with two memory settings to allow switching between maps if the user prefers (for the track and highway say). More memory modules can be added if the user wants to switch between more than two maps. 

BGT were quick to point out that the Microtech has many safety features. One of these is the air temperature sensor (which is fitted with the ECU). This monitors the air intake temps and adjusts fuel if too high. 

BGT offer a 30 day money back guarantee and 12 month warranty.
