Title: Bosch Me 3.82 mapping for 440cc/min injectors Post by: petrolheadr on November 07, 2013, 08:47:30 AM Hello!
I have small project coming on with friends Audi A4 20v 1997 125hp ADR non turbo engine. Could someone please help towards right direction to get it run properly with bigger injectors (440cc)? I have wideband so fine tuning no problem. I need to get info on how to find correct maps how to locate primarly for fuel and spark. Idle enrichment? Part throttle fuel map? WOT enrichment? Maybe some guidelines from some similar ecu can be used? I know its different from Me7 so lack of info. No checksum plugin in winols for this ecu, so maybe there is some better options how to correct it? When car is on 440 injectors it starts only cold engine roughly on 3 cylinders. Hot engine no go to start. I can only write tuned file in with mpps. I don't have ori file yet because I need to desolder eprom with hot air to ge it. the software version is 357964 Bosch 0261204774 VAG 8D0907558B Similar ori file from exact ecu as an example is attached with just different SW 357973 Title: Re: Bosch Me 3.82 mapping for 440cc/min injectors Post by: ported2flow on November 07, 2013, 04:43:19 PM hi i can try to help

He wants to run it on both ethanol and gasoline with same injectors, because stock injectors no good for ethanol.
