ZLET Tuning Packages

The Astra G/Mark 4 Turbo - Hatchback, Coupe and Cabriolet. Providing responsive engines and a competent chassis, this is an excellent all round performer that responds well to the 'Courtenay Touch.' Mind you..... what Vauxhall doesn't?

The Astra Turbo models GSi, SRi, Coupe and Cabrio (OPC in Europe) are fitted with a Z20LET 2.0 turbo charged engine. This power unit is equipped with Motronic M1.5.5 one of GM's more advanced engine management systems. This engine management system is equipped with flash roms, rather than the conventional eprom chips that for example were used in the Calibra and Cavalier Turbos before. The advantage of a flash rom is that the ECU can have the program changed/rewritten again and again with out ever having to break the ECU open.
