>I can't speak for the ZR1 guys, but us Lotus Carlton owners have a very strong owners club in the UK. Of the 380 odd cars sold in the UK, over 200 are known to the club. In the past 5 years I'm aware of about 5 ECU failures. These appear to all be ignition related - misfires that can only be cured by swapping ECU's. I've got about 3 ECU's which have been replaced all with the same reported fault. Some day I'll get round to trying to fix them. My worry is that the fault will be in one one of the Delco specific chips on the iocard. If that happens, then we're going to need 'common' ECU's to scavenge parts from.
