Hi everybody

Is it a way to tune the mixture on a hot wire air flow?

I did'nt find anything in the workshop manual

Thanks by advance for your answers

Mixture should be preset. Are you having emissions problems? Have you got the correct tune resistor?
 
The Afm controls fuel metering but if you have lambdas then the system is closed loop and is pre set at the factory don't not adjust as the 14 cux is a fixed map ecu
 
Hi Vougese

There is no lambda, it's not a catalized one.

What about a kind of BTR screw inside the hole on the hot wire air flow?

I turn mad with that, (i drag this trouble since a while). The spark plug are turning black after few tens of kilometers in the best case. By luck, with LPG, it's working not too bad.

Any Idea ?

Thanks by advance

My spark plugs turn black also but it does run ok. Mine in non cat 3.5efi and it definitely runs very rich. However it recently made 112 miles motorway trip and used around £30 of petrol, which works out at approx 23 mpg which cannot be bad.

What makes you think the mixture is not correct?
 
Hi

No, it start well. Coolant temp, gas temp had been checked, and changed for the first one.

When i'm forced to run with gasoline, i can run 15/20 miles before the engine start to stroke itself. To climb on my mountain, i have to stay in first gear, sometime to pass in low gear.

INobody know what is hiden unden he BTR screw on the air flow meter ?

Thanks by advance
