Title: Fuel Econemy betwen 032HS (wideband) and 032S(narrowband) Post by: Steven97i1 on June 17, 2021, 12:59:54 AM Hey guys, i have a little problem
i accidently drove a Wideband ECU on a narrowband car. the fuel econemy is Great on the Wideband ecu(down to 6-8l easylie) but the Fuel econmy is AWFULL with the "original" ECU with stock stage 1 tuning or even completly stock ecu.(min. 10l average 12-15) i only have Decated the car with 3" Downpipe. Both ecus are Rear o2 off. Why is that so?

I am confused :D i had like 10 ecus laying here, Took one put a Ebey stage 1 on it and threw it in my a3 8l 1.8t with 400.000km just that easy^^ Title: Re: Fuel Econemy betwen 032HS (wideband) and 032S(narrowband) Post by: Steven97i1 on June 17, 2021, 04:08:34 AM Limp mode fuel economy/driving/gauges all incorrect if injectors/kvb different etc. yeah but Car runs better with wideband ECU then with narrowband and with wideband it has better fuel econemy Title: Re: Fuel Econemy betwen 032HS (wideband) and 032S(narrowband) Post by: RBPE on June 17, 2021, 04:21:19 AM yeah but Car runs better with wideband ECU then with narrowband and with wideband it has better fuel econemy If it's converted properly to wide band, otherwise you're just looking at faux figures and the ecu's adaptations are making it feel safe when that would be questionable. Title: Re: Fuel Econemy betwen 032HS (wideband) and 032S(narrowband) Post by: Sandstorm3k on June 17, 2021, 08:55:09 AM Just pull the files and look at them, will most definitely answer your questions.

Its not conerted! Just thtew ecu it it Title: Re: Fuel Econemy betwen 032HS (wideband) and 032S(narrowband) Post by: nyet on June 17, 2021, 08:35:40 PM Its not conerted! Just thtew ecu it it Wait, you have the same O2 sensors? Title: Re: Fuel Econemy betwen 032HS (wideband) and 032S(narrowband) Post by: Blazius on June 18, 2021, 09:20:02 AM Wait, you have the same O2 sensors? Thats what I was saying lol. How do you put the a wideband ecu on a narrowband ecu/harness and run with lambda sensor ( you dont). if you make the switch to wideband harness(add wires) then you cant go back because connector difference. So why are you surprised by fuel "economy" Title: Re: Fuel Econemy betwen 032HS (wideband) and 032S(narrowband) Post by: Steven97i1 on June 18, 2021, 12:29:48 PM I didnt Change anything for the ECU. Just threw ECU in.
