I have for sale a Autronic SM4 ecu, loom (will not suit a cosworth though) and 4 Denso LS-1 individual coil packs. The chip version is version 1.09. Bought direct from Mark Shead £1300 all in.

 

what does it fit?

 

The loom isfor a corsa but mark shead can supply brand new uncut looms for around £100ish iirc.

 

Its about 400 for a fully built loom from MAD IIRC
Or 150+VAT for a bare loom that you then buy the connectors and braiding for etc and make your own, so about 250 all in if you do it that way.

 

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
