Ok, i have a E30 J plate 325i all stadard and have bought a Stage 2 Superchip ECU which i fitted yet it wouldn't start, it'll turn over and try and fire but won't actually kick into life. Re-plug in the original ECU and first turn of the key and she'll start fine.

Theres a label on the ECU that reads;

Batley Superchips and Turbo Systems

Stage 2 Super Chip: Inserted On 20/04/02
Chip Code 10237/989 BOSCH

Any ideas with what i can do? - Do i need other mods to make it start?

Anyone heard/use Batley Turbo Systems/have contact details?

Any help or advice would be appricated.
