33 miles to 15.33 litres ???

[sakib]

Poor mpg but i do mainly short drives like a mile or 2 and engine temp not reached 90 as am.aware car does overfuel when warming up but still carnt be this bad using 15.33 litres and i have only done 33 miles. I have done maf logging just to check it wasnt faulty amd i reads around 180 mg/s 2 gear up to red line so that carnt be causing bad mpg. Only mod i have done is n249 bypass ?? What can cause this???

That's about 9.8mpg so something is way off!

I know :-( i.have spent £1000 pound on service too inc plugs oil filter , fuel filter, engine oil, gearbox oil, haldex oil and filter , new rocker gasket, new sump. Drop link rear links and ball joints alone with new temp sensor and thermostat. And i use shell v power

You have had a fuel filter, do you have a fuel leak somewhere thats the only thing I can see that would cause that bad a fuel economy reading. Or possibly they forgot to put oil in the engine.

Looks like a butterfly to me ??

 

[sakib]

Hahah it does if you join the dots m does it look normal or not??

 

[jimmcgee]

at the top of the chart settings , click on line chart instead of scatter , that will give you a better chart

 

[jimmcgee]

and create 2 gauges , 1 for short term fuel trim and one for long term trims and go drive for 10 miles

Ok will do tommorow back of my head i did have long and short trim on display and long trim started of at 2.3 and stopped at +0.8 to -0.8 at steady driving at 30mph . Will try again tomorow so its more accurate
