Hi,

There is no rolling road where I live,

would colourtune be enough to set my mixture right or should I really invest in a good wideband gauge ?

Witch one would be easier to read into so I can make my engine running safe by my own ?

Thanks

Definately a wideband gauge,

 

The AEM ones are about the cheapest at about 140-150GBP

+1 for the wideband. It's worth its weight in gold if you don't have RR access & want to tune the engine yourself.

Good find!

 

I dont know how it works in Mauritus, but in the UK we would be likely to get charges import duty on top of that.

you do realise there is a bung you have to weld into the exhaust for the sensor to screw into

 

the other thing is once you get the gauge working if your running a carb, you then need to know how to interpret the info so you can select the correct needle or profile the needle.

 

otherwise if its just for setting mixture at tickover which is all a colourtune really does then a gunsons gastester  would be more suited.

I know a little about taxes as I've ordered about 10 times at minispares this last months !!! but it's just 15%VAT here.

 

Yes I know I have to weld the included bung for the O2 sensor, just need to find the right place.

The goal is to find the right needle as mine seems to be too rich.

my manifold is a maniflow coopers not lcb co I think best place would be just after where the two last branches meet ?

Re: a bung. If not permanently installing it to the car, I've had luck making an extension that can slip over the exhaust tip, with the sensor screwed into it. You need to not be too close to the exit (10", iirc) or the numbers will read lean. This doesn't work with catalytic converter, though. But the other recommendations for how close or far from the engine are for permanent installations, and mostly come into play with thr sensor getting fouled by fuel condensation.
