Running rich... Help please

[PhilW]

How do you interpret those figures then bill?

My results are pretty much the same as Daz's.

Don't know if this is of anyhelp to you mate:

Thanks for that Tom. Will try and do some tests/logs later.

Thats not rich for under boost levels...
WOT is not using lambda control its load table related

Right now im confused.... Those A/F ratio's were calculated by inserting my MAF readings into the calculation spreadsheet on the ross-tech website. http://www.ross-tech.net/vag-com/examples/air_fuel_EXAMPLE.xls

Is this not an acurate calcualtion of A/F ratio then?

Am i not actually running rich afterall?

cos his numbers are in the 13's and 12 and below is what I would consider rish.
LBT if I remember rightly is 12.5:1

Depends on the level of uncertainty on the ross-tech calculation.
ibiza sadly lacks the wideband lambda to properly measure the actual.

If you are in fact 13:1 you are not running excessively rich for under boost conditions.

Like you said, be really interesting to see how they compare with wideband logger.

I think Jonzy is gonna do a comparison with his Zeitronix and this calc. Be good to know for future referance.

Thanks for you comments Bill. So its not running overly rich then going by those figures? Not likely to damage my cat the way its running am i?

As you said Phil, i'd be intersted to see how the wideband readings compare.

 

[PhilW]

Spoke to jonzy and aparently the logs show it to be slightly richer than it would be on the wideband.

Oh so my readings are not so bad afterall then?

Cheers Ollie.

nowt wrong with that under boost

 

[ibizacupra]

someone should log with LCR on the ross-tech calc against actual lambda as it has wideband... be an interesting comparison

 

[PhilW]

Yes, that would be a good idea. I'll see if i can get the logs from Jonzy a in the mean time.
