Neil (Enright) has already done this successfully. There is some more information here.

Eerrr no. You want the closed loop 1499 (S2) chip - the 9929/9930 chips don't use the oxygen sensor which is necessary for your catalyst to work properly. The 9930 gets rich SEs (with a 9929 or equivalent PROM) under the UK 3% requirement - no oxygen sensor or catalyst required - it wouldn't get you under 0.4%. The S2 ECU would of course work too (since it has the 1499 chip in it).

Finally a phone line! :-D

On my MOT Exhast Emissions Test Reading (July 31 2007):

Reading CO = 0.16%
HC = 103 ppm

Hope this Helps!

Cheers,

Just to let you all know that this prolem is solved.
Duncan called after 2 days, we did the rebuild 3. day evening, and he passed the MOT day 4 without any problems.

It IS a piece of cake. :!:

especially when you have all the parts you need on the shelf. :wink:

Oh.. Master don't be mad at me, but as you know, I'm just a simpel and stupid dane from who you can not espect knowledge of all the fine details of the english language. So I'm sorry if I hereby offended you by letting the job i have done sound more impressive than it realy is. This will surely not happen again. :wink:

Wrong answer. What you should have said is "complete strip down and rebuild like jimbob - it took a whole day because I had to go to work in the middle of it" :wink:
