Title: Can you calculate AFR on a narrowband ECU? Post by: denniss112 on October 26, 2021, 03:59:49 AM As the title says. Is it possible for a ME7.5 ECU that is narrowband, able to log some data so it can be calculated to a accurate AFR reading?
I will include a log I ran on my Audi TT MK1 180 FWD with a stage 1 tune + pop map on it. Title: Re: Can you calculate AFR on a narrowband ECU? Post by: Sandstorm3k on October 26, 2021, 02:04:52 PM No, logically thinking I don't think there is. Convert to wideband hardware :)

I thought perhaps there would be a excel sheet somewhere floating with some magic calculations, you never truely know until you ask :) Title: Re: Can you calculate AFR on a narrowband ECU?

It could be converted to afr but the range is .. narrow Title: Re: Can you calculate AFR on a narrowband ECU? Post by: nyet on October 27, 2021, 02:57:43 PM Or google It could be converted to afr but the range is .. narrow and completely inaccurate, to the point of being basically useless, depending on the particular narrowband setup. |
