Hello, I think this is the right place to post this.

I was wondering if anybody knows what sigma immobiliser system they fit to lti tx1's? I think it’s a sigma system since the key fob has sigma on it. I was wondering if the newer and the older sigma systems are the same way to add more key fobs to the system? Since I got the M30 Subaru manual off this site.

Thankyou

Yes, the instructions for operating and programming the Subaru system also apply to the standard system fitted to the LTI TX1 taxis. However, as the LTI vehicle had a diesel engine, a coded fuel shut-off valve was also fitted in an enclosure around the fuel pump and one of the immobilisation circuits was replaced by a coded digital link to operate this fuel valve, so the ECUs are not interchangeable and the standard fit LTI unit is designated "M30-LTI".
