My beloved original head-gasket has finally given up after 95K! miles on my 2000 S1 non VVC. My Elise is now in lots of bits feeling sorry for itself. The original plan was to bung a MLS gasket in and stitch it back up but now heavily considering the MEMS 2 143BHP VVC conversion and as I appeciate it's probably been covered 1001 times (albeit I'm struggling to find all the info in one place) I've yet to find anywhere that covers one of my biggest concerns, that being my Cobra 6422 alarm system.
How I see things is at the minute my Cobra 6422 alarm module is seemingly coded to my Lucas 5AS module which in turn is paired to my current non VVC engine ECU. Everything works fine off the Cobra alarm fob so the plan is to use my existing Cobra alarm which seems to decode the 5AS immobiliser then I need it to run the replacement VVC ECU.
Does anyone know anything about this and how do other VVC conversion get round this? Ideally I don't want to forefit my Cobra unit as it's got a Thatcham 1 certificate and I can see my insurers asking questions if they car goes on it being stolen and I'd rather not have to have to use the two button Rover fob to start my car after having already used to the Cobra one to turn the alarm off and open the door.
