Title: mot woes
Post by: Adie Moore on April 02, 2007, 06:13:25 PM
what do you guys think to these figures for my emissions, i know i\'m way off but what can i do to get them down. gonna check the spark plugs when it cooled down but apart from that i\'m a bit stuck.

fast idle
CO 8.01%             Fail
HC 1128ppm          Fail
lambda 0.81           Fail    

natural idle
CO 7.81%             Fail


thanks adie

I have a 97 rsr with a decat, and the good thing for me is my mate does the mot s. All he does is puts my details on the car before , so i get that readout. Easy.

the only thing i know how to do is: settings, then igl/t,fl and lower the inj adj, this was as low as it would go, 500 or 50 or something like that.

yeah i also had a mate that could get me sorted, however, as is the way, he is now inside and has got more important things to worry about.

What year is your car - as the garage that mot\'s mine only do the test at idle? :3Confused

Change plugs, change oil - give it a bit of stick before hand - those should help but wont get you to pass.

I believe the cat should work without the airpump it\'s just that prolonged use will clog the cat up with no airpump.

Is the car using the Apexi base map or has it been mapped?

I\'m off work this Thursday, so all yours. mmmm from MK about 3/4 to 1 hr at a guess. I\'ll drop you a pm with my number. What sort of time would you be around on Thursday? if I need to go out I\'ll leave it outside for you.
