Another fuel problem
Ok got the clivo insured , taxed and MOT'd.
Ran it for a few days now and it eats the fuel!!
10er will do maybe 40-50 miles. Is that right?
Im also not running a lambda sensor, if i put one on will the fuel economy be better?? As with no lambda it will running rich yes?
Happy and sad at the same time

Hi Dave!
Not sure about Lambda but I think yes..
With the fuel consumption,I find that with MAF set to 650,I get 100 miles per tenner.
Hope yer good mate!

you want your multimeter set to measure resistance (ohms) and measure between pins 1 and 6, altho i've never actually dont it, so if they're not actually numbered on the car then maybe someone else would be kind enough to label up a pic?

As far as I know the Lamba measures your emmissions to check that you're not running too lean/rich, but I don't know (nor does anyone i've spoken to) what happens when it's removed..
..However like you, I'm about to find out as i've just de-catted mine, and removed the lambda sensor, fingers crossed! Only difference i've noticed is that the idle vibrations you feel through the car are much stronger than before, but that may just be because it's a free flow exhaust now
I just put £20 in today, so i'll measure how many miles I can clock up on it for you over the next few days

Is that good or bad??martinholmesuk wrote:Dave, You have what's called a B18FT(M) which is a b18ft without the sensor, the ecu goes into closed loop.
Its not running right and gets a missfire/hesitation at higher rpms

Well Dave, I think it's not a problem with having no sensor... Have you changed the coul and rotor/dizzy/leads or have we been down this path because someone else did I'm sure of that.Short term fuel correction uses the oxygen senor to make small changes to the injector duty cycle. Effectivley it's the closed loop control of the mixture done during 'cruse' conditions. This is an offset made to the injector duty (that is calculated from the MAF signal), and acts to get the lambda value as near to 1 as possible. It is calculated 'on the fly' constantly by the ecu.
Long term correction is triggered when the short term correction reaches a particular offset, and the offset value is in one direction. The ECU stores a value that is calculated to bring the lambda value to near 1 in place of the short term correction. Thevalue offsets the entire range of fueling (it's supposed to correct for wear in the injectors, and / or drift in the output of the MAF).

It has had new plugs but leads etc are older and the cap and arm are a bit older aswell.martinholmesuk wrote:Well Dave, I think it's not a problem with having no sensor...

Ill give them a change and see how it is. Its normally in higher gers 3rd and upwards at higher rpms that you feel/hear it.
