Hi Guys
Thanks for the comments.
Just to be clear, my engine is a LH not KE and therefore has much more control all round.
When previously posted, my referral to the 'diag signal' is the signal that is present in the X11. The R129 (from around '92 upto around '95) was fitted with both x11/4 (38pin diag conn) and the traditional x11 (9 pin) connector for fault diagnostics.
I'm specifically interested by the o2 emissions as these are good clues to whether the Cat is hot enough - thanks for letting me know.
