Is My Mixture Too Weak ?

[Fazza6868 0]

Hi new to forum and to 205's so please be gentle

 

 

Firstly I will give you the spec

205 alloy block mi16 on jenvey throttle bodies with ermerald management FSE power boost valve, stainless exhaust , tbular manifold (not sure if standard although has got re-angling plate). I bought the car in its current form therefore do not know much about how its all set up .

 

The car passed its MOT on friday with flying colours I have been driving it over the weekend and all is good.

 

When the emmissions test was done with for the mot the results were as follows

 

CO 0.64 Limit <3.50

HC 34 limit <1200

 

I was showing the results to a good friend of mine who suggested it was running very lean i have noticed although the car is very quick the power does seem a bit lathergic in its delivery . the exhaust is alos leaking a bit too i think between manifold and centre section but could possible be at the manifold what effect would this have?

one other thing to mention the car was peviously fitted with Nitrous which had the jets fitted to the itb trumpets i have removed the jets now but havent managed to replace the trumpets so they all have a 12mm hole in them will this have an effect on performace also.

 

all help is greatly appreciated.

As long as the 12mm holes are on the air filter side of throttle butterflys they should not effect your performance,but they should be blanked off as they are sucking in unfiltered air.

As for the mixture you really need it checking on a rolling road,or better still live as you drive it down the road with the correct equipment.

The Co at idle could have nothing to do with your performance,but I don't know how Emerald works soz

Thanks kev

 

The holes are within the filter housing, what should I expect to pay a mapper for this sought of work ? I live nr northampton are there any reputable companies local that may be able to help/give me some pointers

A quick scan of 'Emerald mapping' on Google will find you something I would think.
