ive no idea martin, does it..?
wish i knew all the earlier, lol

You will need somebody more technical than me to answer that one, but i thought that was the lambda sensors job to control emmisions.Quote:

Got an old PC setup in the lockup today, played with injector mili-second values .. i think lol..
In order to get those CO's down.

I took 20% off the figures @ site 0 and 10% @ site 1, between 750rpm and 1500rpm.. :-s
Im booking it in at the same mot place for a quick emmsions check, if its any better (or lower) than last time but not quite enough then back to the pc and lower them a bit more. I doubt ill have got the car good enough 1st time but if i have: theyll carry out the mot retest. But most likely try again friday. If no difference, the sod it i give up lol.

Other than that looks good mate!!
lambda sensors are needed for setting up, but you dont have to run them full time i dont think..
Ill get some lambda sensors too lol
lol no wonder your fuelling is all over the shot. Stop messing around with it and put an o2 sensor in!
NO you will need the lambda sensor all the time! It controlls the day to day adjustment of air/fuel ratio!Quote:

there are ways of controlling air and fuel on the software anyway.. to a degree. but yes in an ideal world..
anyway; i went to test the emmisions today after our 'mot-map-modification' and its dropped to 5. So near, but not quite.
I managed to reduce the figures furthermore, but then the readings were higher again, nearer 9 so ive reverted back to what scored 5 and been a little more subtle with the reduction. Try again tommorow.
What are you doing to the map? I would be very very careful as to how much you cut the fueling as you really dont wanna be running it very lean!!! You will have worse problems than emmisions! Iv not been folowing this thread so dont know what managment you are using so the lambda might not be needed however i cant see why its not be included in the map. Why dont you get a lambda sensor and try it?
Tbh im not clued up enough to give u a reason why. Ive just never been advised to get a lambda, until now by u lot lol.
I am being safely looked after my bowyer throughout this so dont worry too much, i am aware of adjusting fuelling too much fore/aft.
The map is one of martins (bowyer) proper fully dyno'd, originally for Mike Turpin's yellow rallycross nova but just limitered more.
But yeah, now i just want the thing mot'd for the pv show ive got tickets for and planned for weeks..
Ill do-the-lambda until my hearts content after.
Plus not to mention: If i cant get it to pass and miss the show then no biggy; ill order a lambda (£75) book it in for manifold modification and fitting of boss etc (£100+) then go to a rolling road for a proper full on session. (£450)
