I just recieved Feb 2005 issue of performance Ford through the post and have read the feature that MSD have taken part in concerning Closed loop Lambda control systems. They used andys` ("RS GUS" on here) sapphire RS 4x4 to develop the setup, to get the most out of the older Marelli ECU so emission tests at MOT time can still be passed, better MPG can be gained and better drivability without going to after market engine management, aswell as decent power output I`m sure. I thought it a great feature that showed there is still life left in the old L8 yet, I think its something that many Cosworth owners should think about having done on their cars to save money and get the most out of their old YB`s, once again, another top feature that puts MSD` innovative work on a national bill board, keep up the good work guys
