I have for sale a Autronic SM4 ecu with version 1.09 chipset and loom to suit a LET, 4 Denso individual coil's, Twitchell motorsport trigger disk, crank sensor holder, cosworth crank sensor, and 4 Siemens 750cc/min low Impedance injectors. Its a full setup to fit onto a LET and get it up and running. It is one of the best ecu's available and as a whole package you will not find a better setup for a LET i dont believe.

The ecu spec can be found here:

The 4 Denso individual coils are capable of providing the strongest spark possible and were advised to be used by Mark Shead.

Twitchell Motorsport crank trigger disk and crank sensor holder is so the crank angle trigger is provided in the best possible form for the sm4 ecu.

Siemens 750cc injectors were cleaned and spray pattern checked 12 miles ago.

As a whole package £1500 which is a steal. All in all i dont think you could find a better ecu package to fit any engine
