ECMlink ECMLink... new injectors... AFRatioEst

[white92tsi]

I just installed my 650s... I changed the global fuel settings and dead time as instructed, but AFRatioEst is way off when datalogging. I used the fuel flow factor for afratioest to get it back to where it should be, but I would like to know if there is a better way to tune with larger injectors.

I have a 190 with no afpr if that matters.

Thanks.

Yes... Use a your wideband reading...

There's a video in one of these steps which will show you how to adjust your idle tune

Then do some searching around here and in the link wiki on how to cruise and WOT tune once you have everything in the above link dialed in.

Using my wideband is a given. I am switching to SD soon and using my maf to set up the base ve table. I need the airflow to be as accurate as possible. AFRatio off and wideband correct tells me that either I missed some setting or the airflow settings are way off.

As it turns out, the new injectors are spot on because after clearing out the mafcomp sliders, it is almost perfect with no fuel flow adjustment.

Thanks for the comments... and for the link.
